Callback URI Verification
Verify your newly-created webhook.
This page covers the verification step when first setting up a webhook on Dashboard. Please see our payload verification section for information on how to verify webhook payloads from vehicles.
When you first set up a webhook in the Smartcar Dashboard, Smartcar will post a challenge request to ensure we’re sending payloads to the correct place. This is a one time event and will be in the following format:
Upon receiving the request, your server will need respond to the challenge by hashing payload.challenge
with your application_management_token
to create a SHA-256
based HMAC
.
Our backend SDKs have helper methods to generate the HMAC
.
Return the hex-encoded hash as the value for challenge
in your response body with a 200
status code, and the Content-Type
header set to application/json
.
