Hi Guys,
We recently built an add-on for Gravity Forms that lets you connect to external APIs using form field values — and fill other fields with the response.
It works by:
-
Sending a GET or POST request when a field is filled
-
Using form values as request parameters
-
Populating other fields with returned data from the API
You can also configure custom headers and use different types of authentication, including API Key, Basic Auth, and Bearer Token. Everything runs server-side, and credentials are stored securely.
It’s helpful in many situations — like looking up customer info, displaying details based on a code, or pulling real-time data into forms. It also works with List Fields if needed.
We’ve been using this in a few internal projects and thought it might be useful to others. Curious to hear if anyone else has tackled similar API-based workflows with Gravity Forms.
