With the CaptainForm – GetResponse integration you can import leads in the Contacts section of your GetResponse account through form submissions. You can enable the integration in Form Settings → 3rd Party Apps. Hover over the GetResponse logo from the apps list and click on the Add button.
Next, paste the API key from your GetResponse account in the application box that appears below the list.
To locate the API key, log into your GetResponse account and go to My Account → Integrations → GetResponse API. If you want to disable or remove the GetResponse integration, return to 3rd Party Apps and use either the remove button or the checkbox on the top right corner, depending on your needs.
