Woohoo OAuth + Signature Tester
Configure the client ID, client secret, username and password at the
top of this PHP file. The page automatically calls /oauth2/verify,
then /oauth2/token, then adds Bearer token, dateAtClient and signature.
Use sandbox only until every request succeeds.
Woohoo V3 test-kit rules applied:
- The bearer token is reused for up to one week.
- It is regenerated only after a token_rejected response.
- Successful Catalog responses are cached for 30 days.
- The recommended first product test is SKU CNPIN (ID 324).
- Woohoo must enable test product IDs 324–338 for your account.
