# How to Integrate Lovable with Reddit Ads

- Tool: Lovable
- Difficulty: Intermediate
- Time required: 50 minutes
- Last updated: March 2026

## TL;DR

To integrate Lovable with Reddit Ads, create a Supabase Edge Function that calls Reddit's Ads API using OAuth2 credentials stored in Cloud → Secrets. The Edge Function handles campaign management, ad group configuration, and performance reporting. Use Lovable's chat to build Reddit campaign dashboards that surface community-based targeting metrics and subreddit-level performance data.

## Build Reddit community advertising dashboards in Lovable with the Reddit Ads API

Reddit's advertising platform is built around its community structure: rather than targeting by age, income, or demographic profiles, Reddit Ads targets by subreddit communities and interest categories that map to those communities. An ad targeted to r/personalfinance reaches people actively discussing personal finance topics, which can produce stronger engagement than demographic targeting for products that align with specific interests.

The Reddit Ads API provides programmatic access to campaign creation, ad group configuration (including subreddit targeting and interest targeting), creative management, and performance reporting. The API follows Reddit's standard REST architecture and uses the same OAuth2 infrastructure as Reddit's platform APIs, but with advertising-specific scopes.

Reddit Ads differs from Meta advertising in a fundamental way: Reddit users are actively engaged in topic discussions and resist hard-sell creative. Ads that add value to the conversation (informational, community-relevant, authentic voice) outperform traditional ad formats. Dashboards built on the Reddit Ads API should surface engagement metrics — upvotes, comment sentiment, subreddit performance — alongside traditional click and conversion data.

## Before you start

- A Lovable account with a project that has Lovable Cloud enabled
- A Reddit account with an active Reddit Ads account — create one at ads.reddit.com
- A Reddit developer application registered at www.reddit.com/prefs/apps — you need the client ID and client secret
- OAuth2 access credentials with the ads:edit and ads:read scopes
- Your Reddit Ads account ID — visible in the ads.reddit.com dashboard URL

## Step-by-step guide

### 1. Register a Reddit developer application and obtain credentials

Go to www.reddit.com/prefs/apps while logged into your Reddit account. Click 'Create app' or 'Create another app'. Fill in the name (e.g., 'My Lovable Ads Dashboard') and select the application type. For a server-side app that uses client credentials, select 'script'. For an app where end users log in with their own Reddit accounts, select 'web app'.

For the redirect URI, enter your deployed Lovable app URL if you will implement user-facing OAuth, or use http://localhost:3000/callback for a script-type app. Click 'Create app'.

Reddit displays your application with a client ID (shown below the application name as a short string) and a client secret. Copy both values. For script-type apps, you also need your Reddit account's username and password for the resource owner password credentials flow — but for advertising API access, the standard OAuth2 client credentials or authorization code flow is more appropriate.

To access the Reddit Ads API specifically, your developer application needs the ads:edit and ads:read scopes. These are not standard user API scopes — they require that your Reddit account is connected to an active Reddit Ads account. Go to ads.reddit.com and confirm your advertising account is active and funded before attempting API calls.

Reddit's Ads API documentation is available at ads-api.reddit.com/docs. The API is versioned with a v3 prefix for most endpoints.

**Expected result:** You have a Reddit developer application with a client ID and client secret, and your Reddit Ads account is active with API access enabled.

### 2. Obtain an OAuth2 access token for the Reddit Ads API

Reddit's Ads API uses OAuth2 with the authorization code flow for user-level access. To generate an access token, direct your browser to Reddit's OAuth authorization URL:

https://www.reddit.com/api/v1/authorize?client_id={CLIENT_ID}&response_type=code&state=random_string&redirect_uri={YOUR_REDIRECT_URI}&duration=permanent&scope=ads:read+ads:edit

Replace {CLIENT_ID} with your application's client ID and {YOUR_REDIRECT_URI} with the redirect URI you registered. After authorizing, Reddit redirects to your callback URL with a code parameter. Exchange this code for a token by making a POST request to https://www.reddit.com/api/v1/access_token.

The permanent duration=permanent parameter generates a refresh token alongside the access token. Store both — the access token is valid for one hour, and the refresh token lets you obtain new access tokens indefinitely.

Once you have the access and refresh tokens, store them in Cloud → Secrets in the next step. The Edge Function will handle token refresh automatically using the refresh token when the access token expires.

**Expected result:** You have a Reddit OAuth2 access token, refresh token, client ID, and client secret. The access token is valid for one hour and the refresh token is permanent (until revoked).

### 3. Store Reddit Ads credentials in Cloud → Secrets

Open your Lovable project and navigate to Cloud → Secrets via the '+' icon next to the Preview label. Add the following secrets:

- Name: REDDIT_ADS_ACCESS_TOKEN — Value: your OAuth2 access token
- Name: REDDIT_ADS_REFRESH_TOKEN — Value: your OAuth2 refresh token
- Name: REDDIT_ADS_CLIENT_ID — Value: your Reddit application client ID
- Name: REDDIT_ADS_CLIENT_SECRET — Value: your Reddit application client secret
- Name: REDDIT_ADS_ACCOUNT_ID — Value: your Reddit Ads account ID

All five secrets are needed. The access token is used for immediate API calls. The refresh token enables automatic renewal when the access token expires after one hour. The client credentials are used in the refresh flow. The account ID scopes all advertising API calls to your specific ad account.

Find your Reddit Ads account ID in the ads.reddit.com dashboard — it appears in the URL as a numeric or alphanumeric string after /accounts/.

**Expected result:** All five Reddit Ads secrets appear in Cloud → Secrets with masked values.

### 4. Create the Reddit Ads API proxy Edge Function

Create the Edge Function that proxies Reddit Ads API calls with automatic token refresh. Reddit's Ads API base URL is https://ads-api.reddit.com/api/v3/ and all requests use the Bearer token in the Authorization header.

The function includes a token refresh mechanism: if an API call returns 401, the function uses the refresh token to obtain a new access token from https://www.reddit.com/api/v1/access_token and retries the request. For production use, the refreshed token should be stored back to Supabase (since Deno.env secrets cannot be updated at runtime).

The function handles three main actions: campaigns (list all campaigns), ad_groups (list ad groups with targeting details), and analytics (fetch performance metrics with optional subreddit breakdowns).

```
// supabase/functions/reddit-ads/index.ts
const REDDIT_ADS_BASE = 'https://ads-api.reddit.com/api/v3';
const TOKEN_URL = 'https://www.reddit.com/api/v1/access_token';

async function refreshToken(): Promise<string> {
  const clientId = Deno.env.get('REDDIT_ADS_CLIENT_ID')!;
  const clientSecret = Deno.env.get('REDDIT_ADS_CLIENT_SECRET')!;
  const refreshToken = Deno.env.get('REDDIT_ADS_REFRESH_TOKEN')!;

  const credentials = btoa(`${clientId}:${clientSecret}`);
  const response = await fetch(TOKEN_URL, {
    method: 'POST',
    headers: {
      'Authorization': `Basic ${credentials}`,
      'Content-Type': 'application/x-www-form-urlencoded',
      'User-Agent': 'MyLovableApp/1.0',
    },
    body: new URLSearchParams({ grant_type: 'refresh_token', refresh_token: refreshToken }),
  });
  const data = await response.json();
  if (!data.access_token) throw new Error('Token refresh failed');
  return data.access_token;
}

Deno.serve(async (req) => {
  if (req.method === 'OPTIONS') {
    return new Response(null, {
      headers: {
        'Access-Control-Allow-Origin': '*',
        'Access-Control-Allow-Methods': 'POST, OPTIONS',
        'Access-Control-Allow-Headers': 'Content-Type, Authorization',
      },
    });
  }

  let accessToken = Deno.env.get('REDDIT_ADS_ACCESS_TOKEN')!;
  const accountId = Deno.env.get('REDDIT_ADS_ACCOUNT_ID')!;
  const { action, params } = await req.json();

  let url: string;
  if (action === 'campaigns') {
    url = `${REDDIT_ADS_BASE}/accounts/${accountId}/campaigns`;
  } else if (action === 'ad_groups') {
    url = `${REDDIT_ADS_BASE}/accounts/${accountId}/ad_groups?campaign_id=${params.campaign_id}`;
  } else if (action === 'analytics') {
    const q = new URLSearchParams({
      date_start: params.date_start,
      date_end: params.date_end,
      breakdown: params.breakdown || 'none',
    });
    url = `${REDDIT_ADS_BASE}/accounts/${accountId}/campaigns/${params.campaign_id}/report?${q}`;
  } else {
    return new Response(JSON.stringify({ error: 'Invalid action' }), {
      status: 400,
      headers: { 'Content-Type': 'application/json', 'Access-Control-Allow-Origin': '*' },
    });
  }

  let response = await fetch(url, {
    headers: { 'Authorization': `Bearer ${accessToken}`, 'User-Agent': 'MyLovableApp/1.0' },
  });

  if (response.status === 401) {
    accessToken = await refreshToken();
    response = await fetch(url, {
      headers: { 'Authorization': `Bearer ${accessToken}`, 'User-Agent': 'MyLovableApp/1.0' },
    });
  }

  const data = await response.json();
  return new Response(JSON.stringify(data), {
    status: response.ok ? 200 : response.status,
    headers: { 'Content-Type': 'application/json', 'Access-Control-Allow-Origin': '*' },
  });
});
```

**Expected result:** The reddit-ads Edge Function is deployed. Calling it with { action: 'campaigns' } returns your Reddit Ads campaigns with their status, budget, and objective.

## Best practices

- Always include a descriptive User-Agent header on every Reddit API request — generic or missing User-Agents trigger immediate rate limiting
- Store the refresh token in Cloud → Secrets and implement automatic token refresh since Reddit access tokens expire after one hour
- Cache analytics reports in Supabase — Reddit's reporting has a 24-48 hour lag, so live API calls add latency without providing more current data
- Surface subreddit-level performance breakdowns in your dashboard — this is Reddit's unique value versus other ad platforms and the most actionable insight for Reddit advertising
- Handle Reddit's community-based targeting in your campaign creation UI by accepting r/subreddit names and converting them to the community targeting format the API expects
- Display engagement metrics (upvotes, shares, comments) alongside standard click metrics — Reddit users' community engagement signals are often more predictive of campaign success than CTR alone
- Test with small budgets in a sandbox campaign before building full campaign management features — Reddit does not have a separate sandbox environment and all API calls affect live campaigns

## Use cases

### Subreddit performance analytics dashboard

Build a dashboard showing which subreddits and interest communities drive the best performance for your Reddit campaigns. The dashboard surfaces impression share, CTR, CPC, and conversion rates by subreddit, letting marketers identify high-value communities to expand targeting or exclude underperforming ones.

Prompt example:

```
Create a Reddit Ads analytics dashboard that calls the reddit-ads Edge Function to fetch campaign performance broken down by subreddit. Show a table ranking subreddits by CTR descending with columns for impressions, clicks, CTR, CPC, spend, and conversions. Add a filter for date range and campaign. Highlight the top 5 performing subreddits in green.
```

### Multi-campaign Reddit ad manager

Build a campaign management tool for Reddit Ads that lets marketers create campaigns, configure ad groups with subreddit targeting, set budgets, and manage creative copy — all from a unified Lovable interface without needing direct Ads Manager access.

Prompt example:

```
Build a Reddit campaign manager with a list view of all campaigns showing status, budget, spend, impressions, and CTR. Add a 'New Campaign' form that calls the reddit-ads Edge Function to create a campaign with objective (traffic, awareness, conversions), daily budget, and start/end date. Include an ad group step with subreddit targeting input — accept a list of r/subreddit names and convert them to Reddit community targeting IDs.
```

### Community engagement report for Reddit advertising

Create a reporting tool that tracks not just clicks and conversions but Reddit-specific engagement signals: upvotes, shares, comments, and video completion rates across different communities. This community engagement report helps brands assess organic amplification of their paid content.

Prompt example:

```
Build a community engagement report that fetches Reddit ad performance from the reddit-ads Edge Function with engagement metrics (upvotes, shares, comments, video completions) alongside standard metrics. Display a comparison chart of engagement rate vs. CTR for each subreddit targeted. Export the full report as CSV.
```

## Troubleshooting

### All API calls return 429 Too Many Requests without making many requests

Cause: Reddit's API requires a User-Agent header. Missing or generic User-Agent strings (like 'python-requests' or an empty string) trigger rate limiting immediately.

Solution: Add a descriptive User-Agent header to every fetch call in the Edge Function: 'YourAppName/1.0 by YourRedditUsername'. This is a Reddit API requirement, not just good practice — requests without a proper User-Agent are treated as abusive and throttled.

### OAuth token exchange returns 'invalid_grant' error

Cause: The authorization code used in the token exchange was already used (codes are single-use), the code has expired (Reddit codes expire in 10 minutes), or the redirect URI in the token request does not match the one used in the authorization request.

Solution: Generate a new authorization code by going through the authorization URL flow again. Make sure to use the code immediately after receiving it — Reddit authorization codes expire in 10 minutes and can only be used once. Ensure the redirect_uri parameter in your token exchange POST exactly matches what you used in the authorization URL.

### Analytics endpoint returns empty data for active campaigns

Cause: Reddit Ads reporting has a 24-48 hour lag. Requesting data for today or yesterday may return empty or incomplete results.

Solution: Set the date_end parameter to two days ago when fetching analytics. Reddit's reporting pipeline has a standard lag and real-time data is not available. For dashboards, display data through the day before yesterday and note the lag in the UI so users understand why today's data is not shown.

## Frequently asked questions

### Does Reddit Ads API require special approval beyond a developer account?

Basic Reddit API access (developer app registration) is self-serve and does not require special approval. However, the Ads API specifically requires an active Reddit Ads account with billing information and spending history. Some API features, like Custom Audiences and Conversion Pixel access, may require you to contact Reddit's advertising support team to enable. If you see 403 errors on specific endpoints despite having valid credentials, check whether those endpoints require additional enablement for your account.

### How does Reddit's subreddit targeting work in the API?

Reddit Ads allows you to target by specific subreddit communities, interest categories that aggregate related subreddits, or both. When creating ad groups via the API, subreddit targeting is specified as a list of subreddit names (without the r/ prefix) in the targeting facets. Reddit validates that the subreddits exist and are eligible for advertising — some subreddits opt out of advertising or are ineligible due to content policies. Interest targeting uses Reddit's predefined interest taxonomy which maps to clusters of related subreddits.

### What metrics does Reddit Ads API provide that other platforms do not?

Reddit provides unique engagement metrics reflecting the platform's community dynamics: upvotes on promoted posts, organic post upvotes amplified by paid reach, comment counts on promoted posts, and video completion rates by community. These metrics help assess whether your ad resonates with the community it targets, which is more relevant for Reddit's culture than pure CTR. Building dashboards that surface upvote rate alongside CTR provides a more complete picture of Reddit campaign effectiveness.

### Can I automate Reddit Ads budget management through the Lovable integration?

Yes — the Reddit Ads API supports updating campaign budgets and status through the PATCH campaigns endpoint. You can build a Lovable dashboard with budget management controls: increase daily budget when performance is strong, pause campaigns that exceed cost-per-result targets, and reallocate budget between campaigns. All these operations go through the Edge Function and require the ads:edit scope on your OAuth token.
