This page contains the setup guide and reference information for the 123FormBuilder connector.

Prerequisites

Before connecting your 123FormBuilder account, ensure that:

  • You have an active 123FormBuilder account.

  • You know whether your account is hosted on the US (api) or EU (api-eu) environment, as this determines the correct subdomain.

Setup Guide

Follow these steps to connect your 123FormBuilder account:

  1. Log in to your Keragon account and navigate to the Authentications tab and select to create a new authentication.

  2. Select the 123FormBuilder connector.

  3. Enter the email address and password associated with your 123FormBuilder account.

  4. In the Subdomain field, select either:

    • api for accounts hosted in the US, or

    • api-eu for accounts hosted in the EU.

  5. Click Connect to complete the integration.

Note: Ensure that your account credentials are correct and the subdomain selection matches your account region. Incorrect subdomain selection will cause authentication failures.

  • Authentication requires basic credentials (email and password); OAuth is not supported.

  • Users must select the correct subdomain (api or api-eu) based on account region—this is critical for successful authentication.

  • Only one webhook can be configured per form at a time in 123FormBuilder.
