How to integrate a QR code generator in Bubble

You can integrate a QR code generator in Bubble either by using a simple QR‑Code plugin from the Bubble plugin store or by calling an external QR API through the API Connector. The easiest reliable method is using a free external API because it gives you full control, works instantly, and does not require installing anything heavy.

Quick Working Method (API Connector)

You’ll create an API call that returns an image (the QR code) and then display that image in an Image element or save it to your database.

• Install Bubble’s API Connector.
• Add a GET request to a QR service such as api.qrserver.com.
• Send the text you want encoded, Bubble returns an image URL.
• Use that URL anywhere in your app (Image element, save to DB, send by email, etc.).

// Example GET endpoint for QR code generation
https://api.qrserver.com/v1/create-qr-code/?size=300x300&data=Hello%20World

Detailed Steps

Install API Connector: Go to Plugins → Add Plugins → search “API Connector” → Install.

• Create a new API and name it “QR Generator”.
• Add a call with method GET.
• Set the URL to:
  https://api.qrserver.com/v1/create-qr-code/?size=300x300&data=your\_text
• Replace your\_text with a Bubble dynamic parameter, for example data={{text}}.
• Check “This returns data”. For this API, set the response type to Image.
• Initialize the call. It will return an image URL.

Use the QR Code in Your App

• Add an Image element and set its source to “Get data from an external API → QR Generator → text = Input’s value”.
• Or run it inside a backend workflow and store the returned URL in a database field.

This method is fast, free, and works well for both public and backend workflows, including generating QR codes for tickets, user IDs, receipts, etc.
