Sampled — shipped under file-level sampling, not individually fact-checkedcommunity attestations: 0✓ / 0✗
Steps
Stand up an HTTPS endpoint capable of receiving POST requests from WHCC
POST callbackUri (your endpoint URL) to /api/callback/create with your bearer access token
Capture the verifier code WHCC immediately POSTs to your callbackUri
POST that verifier value to /api/callback/verify with your bearer token to prove endpoint ownership
Validate the HMAC signature WHCC attaches to each subsequent webhook delivery before trusting its payload
Known gotchas
Each set of API credentials supports only a single active webhook address at a time — registering a new one replaces the old
You must complete the verify step before WHCC will actually deliver order-status events to the endpoint
WHCC signs webhook payloads with an HMAC signature specifically so you can confirm authenticity — skipping signature verification lets anyone spoof order-status callbacks to your endpoint
