Using Webhooks, you can connect services with eachother. For instance: You can install the Webhooks Add-on to Gravity Forms on your WordPress website. You can then define 0 to many Webhooks. Each Webhook delivers the form data in the required form (JSON/ Form fields) to any desired URL.
To test the data that is generated, there is this great Webhook Site service. On visiting, you get an URL target for your Webhook. This target URL is then used in the Webhook with the Gravity Form. Upon submitting the form, you can see the data generated on the Webhook.Site webpage.
