# Robinhood API

- Tool: FlutterFlow
- Difficulty: Advanced
- Time required: 2-3 hours
- Last updated: July 2026

## TL;DR

Connect FlutterFlow to Robinhood by routing all calls through a Firebase or Supabase proxy — Robinhood has no official public API. Any integration uses unofficial session-token endpoints that violate Robinhood's Terms of Service and can break without notice. For a real product, use Plaid instead. If you proceed for personal use only, the proxy holds the session token and the FlutterFlow app never communicates with Robinhood directly.

## Before You Build: There Is No Official Robinhood API

Let's be clear from line one: Robinhood does not offer a public API. Any 'Robinhood integration' you find described online uses the same unofficial REST endpoints that Robinhood's own iOS and Android apps call — specifically, a session/bearer token obtained from a POST to /oauth2/token/ on api.robinhood.com. Robinhood's Terms of Service explicitly prohibit third-party automated access to these endpoints. Accounts using them can be suspended or permanently banned, and the endpoints themselves can change or disappear overnight with no warning and no error contract. If you are building a product for other people's accounts, the correct path is Plaid, which officially aggregates Robinhood brokerage data with a documented, stable, ToS-compliant API.

If you are building a personal-use project and fully accept these risks, here is the FlutterFlow-specific architecture: the session token and any login credentials must never appear in your Flutter app bundle. A compiled Flutter APK or IPA can be decompiled, and anything stored in an API Call header or Dart constant ships with the binary. A leaked brokerage session token means someone can read — or potentially act on — a real brokerage account. Every call to Robinhood must route through a Firebase Cloud Function or Supabase Edge Function proxy that stores and refreshes the session token entirely on the server.

Because Robinhood has no webhooks and no documented push events, your app must poll for updates. To avoid triggering Robinhood's IP-based rate limiting on your proxy server's outbound IP range, throttle polling to no faster than approximately every five minutes. Keep all Robinhood field-mapping isolated in one API Group in FlutterFlow so that when an endpoint changes — and it will — the fix is one update in one place, not scattered across multiple screens.

## Before you start

- A Firebase project with Cloud Functions enabled (Blaze pay-as-you-go plan required) OR a Supabase project with Edge Functions
- A Robinhood account you own personally, with full understanding and acceptance of the ToS risk
- A FlutterFlow project on Starter plan or above (API Calls are available on paid plans)
- Basic familiarity with deploying serverless functions (Node.js for Firebase or Deno for Supabase)
- A Plaid developer account if you choose the recommended official path for brokerage aggregation

## Step-by-step guide

### 1. Step 1: Understand the risk and consider Plaid as the production-safe alternative

Before writing any code, make an informed architectural decision. Robinhood's Terms of Service, specifically the restrictions on automated platform access, prohibit third-party apps from calling their internal endpoints. The unofficial endpoint at https://api.robinhood.com/oauth2/token/ issues a session/bearer token that works today but has broken before when Robinhood updated their mobile apps. Accounts detected using automated access have been suspended — this is a real user account with real money, not a sandbox environment.

The recommended alternative for any user-facing product is Plaid (https://plaid.com). Plaid's Investments product officially aggregates brokerage data from Robinhood and dozens of other brokerages. Users authenticate through Plaid Link, a hosted UI widget that Robinhood officially supports. The API is documented, versioned, and stable — it will not silently break overnight. Plaid has a free Sandbox environment you can use today without a paid account.

If after reading all of this you are proceeding with the unofficial Robinhood endpoints for a personal project, proceed to Step 2. Keep your usage strictly personal, never ask other users to enter their Robinhood credentials into your app, and build the Plaid path in parallel so you have a fallback ready when the unofficial endpoints inevitably change. Consider whether the integration is worth the maintenance burden before investing significant build time.

**Expected result:** You have made an informed, documented decision about the approach. You understand the account-suspension risk, the endpoint-instability risk, and have evaluated Plaid as an alternative.

### 2. Step 2: Deploy a Firebase Cloud Function proxy that handles login and session storage

The session token from Robinhood's login endpoint grants full brokerage account access. It must never appear inside a FlutterFlow API Call header, an App Value, or Dart custom action code — all of these compile into the app bundle and can be extracted from a decompiled APK. Instead, deploy a Firebase Cloud Function that performs the Robinhood authentication and stores the session token in Firestore, accessible only to the function.

In your Firebase project (Blaze plan required for Cloud Functions), create a new function in Node.js 18. The login function accepts a trigger from your FlutterFlow app and POSTs the Robinhood credentials to https://api.robinhood.com/oauth2/token/ using the same client_id and grant_type=password payload that Robinhood's mobile apps use. Store the returned access_token and refresh_token in a Firestore document, encrypted at rest by Google. Keep your Robinhood username and password in Firebase Functions config environment variables (not hardcoded in the function file): firebase functions:config:set robinhood.username='...' robinhood.password='...'.

Create a second function, GetPositions, that reads the stored access_token from Firestore and forwards it as a Bearer Authorization header when calling https://api.robinhood.com/positions/?nonzero=true. If the call returns 401, attempt a token refresh using the stored refresh_token before surfacing an error to the app. This two-function pattern — Login and GetPositions — is the minimum viable proxy. Add additional proxy endpoints for /portfolios/ or /quotes/ as your app needs them, all following the same pattern: read token from Firestore, call Robinhood, return the data.

```
// Firebase Cloud Function proxy — index.js
// Run: firebase deploy --only functions
const functions = require('firebase-functions');
const admin = require('firebase-admin');
const axios = require('axios');
admin.initializeApp();

// Login function: stores session token in Firestore
exports.robinhoodLogin = functions.https.onCall(async (data, context) => {
  const cfg = functions.config().robinhood;
  const resp = await axios.post('https://api.robinhood.com/oauth2/token/', {
    username: cfg.username,
    password: cfg.password,
    grant_type: 'password',
    // Robinhood's well-known public client_id used by their mobile apps
    client_id: 'c82SH0WZOsabOXGP2sxqcj34FxkvfnWRZBKlBjFS',
    scope: 'internal',
    expires_in: 86400,
    device_token: data.deviceToken || 'flutter-proxy-device',
  });
  const { access_token, refresh_token } = resp.data;
  await admin.firestore().doc('robinhood/session').set({
    access_token,
    refresh_token,
    updated: Date.now(),
  });
  return { ok: true };
});

// GetPositions: reads token, calls Robinhood, returns positions
exports.robinhoodPositions = functions.https.onCall(async (data, context) => {
  const doc = await admin.firestore().doc('robinhood/session').get();
  if (!doc.exists) {
    throw new functions.https.HttpsError('unauthenticated', 'No session — call login first.');
  }
  const { access_token } = doc.data();
  try {
    const resp = await axios.get(
      'https://api.robinhood.com/positions/?nonzero=true',
      { headers: { Authorization: `Bearer ${access_token}` } }
    );
    return { results: resp.data.results };
  } catch (err) {
    if (err.response?.status === 401) {
      throw new functions.https.HttpsError('unauthenticated', 'Token expired. Re-login required.');
    }
    throw err;
  }
});
```

**Expected result:** Firebase Cloud Functions are deployed. A test call to robinhoodLogin stores a session token in Firestore. A test call to robinhoodPositions returns a list of positions. Both functions appear in the Firebase Console under Functions.

### 3. Step 3: Create a FlutterFlow API Group pointing to your proxy

With the proxy running, set up the FlutterFlow side. Open your project and click API Calls in the left navigation panel. Click the blue + Add button, then select Create API Group. Name the group RobinhoodProxy. For the Base URL, enter the base URL of your Firebase Functions project: https://us-central1-YOUR-PROJECT-ID.cloudfunctions.net. You are pointing FlutterFlow at your proxy, not at api.robinhood.com.

Inside the group, click + Add API Call. Name the call GetPositions. Set the method to POST (Firebase callable functions use POST) and the path to /robinhoodPositions. In the Body tab, set the content type to JSON and add the body: {}. If you are using Firebase Auth to protect your function, add an Authorization header in the Headers tab with value Bearer {{authToken}} and create the authToken variable in the Variables tab — this would be the Firebase Auth ID token from your logged-in FlutterFlow user.

Switch to the Response & Test tab. Paste a sample response JSON in the body field (see the code block below), then click Generate JSON Paths. FlutterFlow will automatically create paths like $.results[0].quantity and $.results[0].average_buy_price. Create a FlutterFlow Data Type called StockPosition with fields: quantity (String), averageBuyPrice (String), instrumentUrl (String). Map the generated JSON paths to this Data Type. Click Test API Call to verify a live 200 response from your proxy before moving to the UI.

```
// Paste this sample in the FlutterFlow Response & Test tab
{
  "results": [
    {
      "instrument": "https://api.robinhood.com/instruments/450dfc6d-5510-4d40-abfb-f633b7d9be3e/",
      "quantity": "5.00000",
      "average_buy_price": "145.23",
      "intraday_quantity": "0.00000",
      "updated_at": "2025-01-15T10:30:00Z"
    }
  ]
}
```

**Expected result:** The RobinhoodProxy API Group is visible in the left nav. Clicking Test API Call returns a 200 response with positions data from your proxy. JSON paths for quantity and averageBuyPrice are generated and visible.

### 4. Step 4: Build a portfolio list screen and bind data

Add a new Screen and name it Portfolio. In the widget tree, add a ListView widget. Select it, open the Backend Query panel, choose API Call as the data source, select RobinhoodProxy → GetPositions, and set the List Type to StockPosition. FlutterFlow will automatically call your proxy when this screen loads and populate the list.

Inside the ListView item template, add a Container for card styling with rounded corners (border radius 12, shadow enabled). Inside the Container, add a Column with two Rows. The first Row contains a Text widget for the ticker (bound to your position's instrumentUrl — note that Robinhood returns instrument URLs rather than ticker symbols directly; for a quick build, store a small static mapping in App State to resolve common tickers). The second Row contains a Text widget for quantity (bound to $.results[].quantity) and a Text widget for average buy price (bound to $.results[].averageBuyPrice).

For the header of the screen, add a Text widget showing 'My Portfolio' and a subtitle showing the total number of positions. Bind the subtitle to the length of your StockPosition list (available via the List Count property in FlutterFlow's binding panel). Add a CircularProgressIndicator widget that shows while the backend query is loading — set its Visibility to only show when the API Call status is Loading.

To display current market value rather than just average buy price, you need a second proxy endpoint that calls Robinhood's /quotes/?instruments=... with the instrument URLs. Add a second API Call in your group called GetQuotes with the instruments list as a query variable, call it from a Periodic Action, and store the current prices in a second App State list that you combine with positions for display.

**Expected result:** The Portfolio screen renders a scrollable list of position cards. Each card shows the instrument reference, quantity, and average buy price bound from the StockPosition Data Type. A loading spinner appears while data is fetched.

### 5. Step 5: Add a throttled Periodic Action to poll for updates

With no Robinhood webhooks available, your app must poll the proxy to get fresh data. FlutterFlow supports this via a Periodic Action on a screen. Select the Portfolio screen in the widget tree, open the Actions panel in the right sidebar, and look for the Periodic Action trigger. Set it to fire every 300,000 milliseconds (5 minutes). Inside the Periodic Action, add a Backend/API Call action pointing to GetPositions and update the App State variable holding your positions list with the refreshed data.

Also add an On Page Load action that calls GetPositions immediately when the screen opens — this ensures the user sees data right away without waiting up to 5 minutes for the first poll. The On Page Load and the Periodic Action both trigger the same GetPositions call.

Five minutes is the minimum recommended polling interval for calls originating from a single Cloud Function IP. More frequent polling risks triggering Robinhood's IP-based rate limiting, which can block your entire Cloud Function outbound IP range — blocking all app sessions simultaneously. If your app might have multiple simultaneous users triggering the proxy, increase the interval to 10 minutes.

Add error handling to the Periodic Action: chain a Conditional Action after GetPositions that checks if the API response status code is not 200 or 201. If an error is returned, update an App State Boolean called hasRefreshError to true. Add a small error banner widget to the Portfolio screen that is only visible when hasRefreshError is true, showing 'Portfolio data may be stale — pull down to retry.' This gives users clear feedback without breaking the entire screen.

**Expected result:** The Portfolio screen refreshes automatically every 5 minutes. Data loads immediately on screen open. If the proxy returns an error, an error banner appears. The user can pull to refresh at any time.

### 6. Step 6: Handle token expiry and endpoint failures gracefully

Unofficial Robinhood endpoints fail in two distinct ways: token expiry (returns 401) and silent endpoint changes (returns 404 or an unexpected response shape). Your proxy should handle each differently.

For 401 token expiry, add refresh logic in your Cloud Function: when GetPositions receives a 401 from Robinhood, the function automatically POSTs to /oauth2/token/ with grant_type=refresh_token and the stored refresh_token. If the refresh succeeds, the function updates Firestore with the new tokens and retries the original request transparently. If the refresh also fails (the token has been fully revoked), the function returns a JSON body like {"error": "session_expired"} to FlutterFlow.

In FlutterFlow, add a Conditional Action on the GetPositions error path: check if the error response contains 'session_expired' and, if so, navigate to a Reconnect screen that explains the session has ended and prompts re-authentication (which calls your Login proxy endpoint again).

For endpoint changes — the more insidious failure — add a Conditional Action that checks whether the returned results array is null or empty when you expected data. Show a 'Service temporarily unavailable' message. In your proxy, log all unexpected response shapes to a Firestore errors collection with timestamp and full response body so you can diagnose changes quickly. Consider a Cloud Scheduler job that pings the positions endpoint every hour and sends an alert if the response shape changes — you want to know about endpoint breakage before your users do. If building and maintaining all of this proxy and monitoring infrastructure sounds like a lot, RapidDev's team handles FlutterFlow integrations like this every week — free scoping call at rapidevelopers.com/contact.

**Expected result:** The proxy handles 401 by refreshing the token transparently. If the session is fully expired, FlutterFlow shows a Reconnect screen. Endpoint changes show a user-friendly fallback message, and errors are logged to Firestore for debugging.

## Best practices

- Never put Robinhood session tokens, credentials, or any brokerage auth data in FlutterFlow API Call headers, App Values, or Dart code — the proxy is the only place they exist.
- Frame any unofficial Robinhood integration as strictly personal-use only; never ask other users to enter their Robinhood credentials into your app.
- Keep all Robinhood endpoint paths in a Firestore runtime config document so you can update them without redeploying your Cloud Function when endpoints change.
- Poll no faster than every 5 minutes from your proxy; 10 minutes is safer when multiple devices or users may share the same function IP.
- Handle both 401 (token expiry with refresh) and 404/unexpected-shape (endpoint change) as separate error paths with different recovery flows.
- Add a monitoring job (Cloud Scheduler) that pings the positions endpoint hourly and alerts you if the response shape changes — know about breakage before users do.
- Build the Plaid integration path in parallel as a production-safe fallback; Plaid officially supports Robinhood brokerage data aggregation and will not break silently.
- Log all proxy errors with full response bodies to Firestore so you have a debugging trail when unofficial endpoints change without notice.

## Use cases

### Personal portfolio tracker showing your own Robinhood positions

A developer builds a Flutter app to display their own Robinhood stock positions and balances on a clean mobile dashboard. The app polls their Firebase proxy every five minutes and surfaces current holdings. Because this is strictly personal-use and the developer accepts the ToS risk, no other user's credentials are involved and the risk profile is contained.

Prompt example:

```
Build a portfolio screen that shows my stock positions, quantities, and average buy prices from my proxy backend, refreshing every 5 minutes automatically.
```

### Brokerage aggregation app using Plaid as the safe alternative

A fintech founder wants to display users' brokerage holdings in a FlutterFlow app. After reviewing the ToS risks, they connect to Plaid's official Investment Holdings API, which supports Robinhood accounts through Plaid's brokerage link. Users authenticate through Plaid Link and the app shows holdings and balances without violating Robinhood's ToS.

Prompt example:

```
Show a user's connected brokerage holdings using Plaid, with a scrollable list of positions and a total portfolio value, refreshing when the user pulls down.
```

### Single-account demo display for financial education content

An educator builds a demo app that shows positions from a controlled Robinhood demo account to illustrate what a portfolio screen looks like. Because it uses one fixed developer account routed through a proxy and no end-user data is involved, the risk surface is narrower than a multi-user scenario.

Prompt example:

```
Display a watchlist of positions with ticker symbols, quantities, and average buy prices fetched from a backend proxy, rendered as cards with color-coded gain or loss indicators.
```

## Troubleshooting

### Proxy returns 401 Unauthorized immediately after a successful login

Cause: Robinhood issued an MFA challenge during login (look for mfa_required or challenge fields in the login response). Without completing the challenge, no access_token is issued and the stored token is empty or invalid.

Solution: Add MFA handling to your proxy: check the login response for an mfa_required field. If present, return the challenge to FlutterFlow so the user can enter their MFA code, then POST the code to Robinhood's challenge endpoint before receiving the final access_token and refresh_token.

### Positions endpoint returns 404 Not Found or an HTML page instead of JSON

Cause: Robinhood has changed or removed the unofficial endpoint path. This is the most common failure mode — unofficial endpoints can change without notice when Robinhood updates their mobile apps.

Solution: Search community resources (GitHub repositories tracking the unofficial Robinhood API, relevant subreddits) for the current correct endpoint path. Update your proxy's endpoint URL in the Firestore config document and test again. This is the core risk of building on an unofficial API.

### API calls from FlutterFlow web preview fail with XMLHttpRequest error

Cause: The Firebase Cloud Function does not include CORS headers, and the browser's same-origin policy blocks the request from FlutterFlow's preview origin.

Solution: Firebase callable functions (onCall) handle CORS automatically and are the recommended approach. If you used onRequest instead, add the cors npm package: wrap your handler with cors({ origin: true })(req, res, () => { yourHandler }).

```
const cors = require('cors')({ origin: true });
exports.robinhoodPositions = functions.https.onRequest((req, res) => {
  cors(req, res, async () => {
    // your handler logic
  });
});
```

### All proxy calls return 429 Too Many Requests or connection times out

Cause: Robinhood's rate limiter has blocked the Cloud Function's outbound IP range due to too-frequent polling, possibly from multiple simultaneous app sessions.

Solution: Increase the Periodic Action interval to 10 minutes. Add exponential backoff in the proxy: on a 429, wait 60 seconds before retrying. Consider decoupling app polling from Robinhood calls entirely: have a Cloud Scheduler job write Robinhood data to Firestore on its own schedule, and have the app read from Firestore rather than triggering a proxy call on every poll.

## Frequently asked questions

### Is it against the law to use Robinhood's unofficial endpoints?

Using Robinhood's unofficial endpoints violates their Terms of Service, which is a contract violation rather than a criminal matter in most jurisdictions. However, Robinhood can suspend or permanently ban accounts detected using automated access, and they have done so. It also means you are building on an endpoint that can disappear without notice. For any product serving other users, use Plaid instead.

### Can I put the Robinhood session token in a FlutterFlow App Value or environment constant?

No. App Values and Dart constants are compiled into the app bundle. A FlutterFlow app distributed to users can be decompiled, and any hardcoded string — including a session token granting brokerage account access — can be extracted. The token must live exclusively in your Firebase Cloud Function or Supabase Edge Function and must never appear in client-side code.

### Why do I need to limit polling to every 5 minutes? Can't I refresh every 30 seconds?

Robinhood applies IP-based rate limiting on these unofficial endpoints. Frequent polling from a Cloud Function's shared outbound IP range risks getting that IP blocked — which would break the integration for all simultaneous app sessions using the same function. A 5-minute minimum reduces that risk; 10 minutes is recommended if multiple devices may poll concurrently. A blocked IP affects all users at once, making this a single point of failure.

### The integration worked last week but now everything returns 404. What happened?

Robinhood has no obligation to maintain or document these unofficial endpoints. Paths, authentication parameters, and response shapes can change anytime when Robinhood updates their mobile apps. Check third-party community resources tracking the unofficial API for the current correct paths, update your proxy config document, and redeploy. This is the core operational risk of building on an unofficial API.

### Does this work in FlutterFlow's web preview mode?

It will work in web preview if your Firebase Cloud Function includes proper CORS headers allowing the FlutterFlow preview origin. Firebase callable functions (onCall) handle CORS automatically, which is why they are recommended over onRequest. Native iOS and Android builds do not have CORS restrictions and work regardless of function type.
