Opening a technical ticket
The more complete the report, the faster the answer. Before opening the ticket, gather:
| Item | Where to find it |
|---|---|
requestId | The requestId field of the error response |
| Date and time of the call | With time zone, or as epoch |
| Method and route | e.g. POST /suppliers/v1/suppliers |
| Environment | Sandbox or Production |
| HTTP status and error body | Copy the whole response |
| Credential API key | The key only, never the secret |
If the error is 401 with details.reason set to INVALID_SIGNATURE
The response does not detail why the signature was refused. To find your call, we need:
- the fingerprint of the key used, 8 characters long, shown in the playground signing card
- the value of the
Signature-Inputheader you sent, which carriescreatedandnonceand is not a secret - the method and the route with its query, exactly as sent
- the exact body of the request
Before opening a ticket, verify the signature locally by following Request Signing. Most refusals come from a signed base that differs from the request that was sent, or from a clock more than 300 seconds off.
Never send the API secret, the access token, or the private key in a ticket, through any channel. They are not needed for diagnosis, and Conta Simples does not ask for them.
