This plugin can sign the webhook events sent by the Gravity Forms WebHooks Add-On to your endpoints by including a signature in each event’s <code>X-Gform-Signature</code> header. This allows you to verify that the events were sent by the Gravity Forms add-on, not by a third party. As of right now, you must verify the signatures by manually using your own solution. However, an example of a Node.js (JavaScript) implementation is linked below.
Before you can verify signatures, you need to retrieve your endpoint’s public key (more information at <a href="#how%20can%20i%20verify%20the%20signature%3F" rel="nofollow ugc">this question</a>).
This plugin uses the same keys for every form and endpoint, meaning that the same keys will be used for every signature generated.
