API Documentation > Webhooks

For select API methods, we’ll send JSON encoded data via an HTTP POST request to a remote url of your choice. You can then capture that data and act on it. If an API method supports it simply provide your webhook endpoint URL along with your request.

Supported Methods
Webhook Signing
All webhook responses will be signed using your API Secret Key.
Signature Verification
  • Concatenate your API Secret Key and the signature_salt from response
  • Generate an md5 hash using the concatenated string as input
  • Compare the resultant hash to the signature from the response.
  • If your hash matches the signature from the response the signature is valid.
