The API Connector for Gravity Forms makes it easy to link your forms with external APIs. You can send GET or POST requests, pass form values as parameters, and map API responses back into your form fields in real time. This allows you to create dynamic, data-driven forms that respond instantly to user input. Because requests run server-side, your API keys and sensitive data stay secure throughout the process.

If you’re new to Gravity Forms, check out our Advanced Merge Tags add-on to see how merge tags and modifiers can work alongside API responses for even more powerful integrations.

FAQ – API Connector for Gravity Forms

Here are some of the most common questions users have about the API Connector add-on, along with clear, practical answers.

What does the API Connector do?

It connects a Gravity Form to external APIs, sends requests (GET or POST) using form values, and maps the API response back into one or more form fields

Where do I add API connections and credentials?

Go to Forms → Settings → API Connector. There, you can add multiple API connections. Once saved, they’re selectable in each form’s API Connector feed.

How do I configure a feed for my form?

Open Form Settings → API Connector → Add New. Choose the saved API connection, pick the request method, set the endpoint URL, and select the input type (Regular Fields or List Columns).

Can I use form values in headers or query parameters?

Yes. In the feed settings, you can map headers and query string parameters from form fields, or use custom values with merge tags. This makes it easy to pass dynamic data into your requests.

How do I map the API response to fields?

Use the Target Fields setting and provide a response path. JSON properties are addressed with / (e.g., 0/weight/imperial). If you’re unsure of the structure, you can capture the response and use the built-in JSON path parser to identify available properties.
