Verifying JWT Tokens from Webhooks
Webhooks often carry a JWT so the receiver can confirm the request really came from the provider. Verifying that token is what keeps the endpoint secure.
Why verify inbound tokens
A webhook endpoint is public, so anyone can POST to it. Verifying the JWT signature with the provider secret proves the payload is genuine and not a forgery from a third party.
Debugging failures
When verification fails, decode the token to inspect the claims, confirm you are using the correct secret, and check the algorithm matches what the provider documents. Subtle secret mismatches (extra whitespace, wrong environment) are common culprits.
