AFI
Advanced Custom Fields
Acf is a WordPress platform. Advanced Form Integration sends form submissions to Acf, so every form entry on your WordPress site can create or update records automatically without manual data entry.
What you’ll need
- An active Acf account.
- An API key from Acf (see below).
- The Advanced Form Integration plugin installed and activated.

Acf authenticates with an API key.

- Navigate to the API or integrations section in your account settings.
- Generate or copy your API Key.
- In WordPress, go to AFI → Settings → Acf, click Add New Account, and paste the key.

Conditional logic example
Only send data to Acf when the form’s email field is not empty, so test submissions or incomplete entries do not create records. Add a condition: Email is not empty.
Troubleshooting
Nothing arrives in Acf
Open AFI → Log and find the most recent entry for this integration. AFI stores the request it sent and the raw response it got back. If there is no log entry at all, the trigger never fired: re-check the form selection and submit a real test entry from the front end.
API key rejected
Copy the key directly from Acf with no leading or trailing spaces. If the key was revoked or regenerated, update it in AFI → Settings → Acf.
