Steps
Authenticate with a bearer access token.
Create a webhook configuration specifying the destination URL and the topics array (currently PRINT_JOB_STATUS_CHANGED is the only supported topic).
Verify each incoming webhook by computing an HMAC-SHA256 of the raw request body using your API secret and comparing it to the Lulu-HMAC-SHA256 header — hash the raw bytes, not a re-serialized JSON object.
Parse the payload's topic and data fields; for PRINT_JOB_STATUS_CHANGED, data matches the same shape as the Print-Job details endpoint response.
Use the test-webhook-submission endpoint to send dummy data to your configured URL and confirm your receiver handles it correctly before going live.
Known gotchas
After 5 consecutive failed delivery attempts, Lulu automatically deactivates the webhook (is_active becomes false) — you must explicitly update it to reactivate.
HMAC validation fails silently if you parse the body to JSON and re-serialize before hashing; hash the exact raw response bytes instead.
