The codes shown correspond to the ReturnCode field returned during card validation. When the feature is not enabled for the merchant, the API returns technical errors in the Code and Message fields.
See the possible values and their descriptions in the table below.
ReturnCode or Code | ReturnMessage or Message | Description |
|---|---|---|
| 00 | Transaction authorized | Card valid for transactions. |
| 57 | Authorization denied | Card invalid for transactions. |
| 322 | Zero Dollar Auth is not enabled | Zero Auth is not enabled. To enable it, contact Cielo support. |
| 389 | Registration restriction | Card validation failed. Check with your commercial representative if the service is enabled for the merchant. If the configuration is correct, try validating with another card. |
Codes and behaviors in the Sandbox may differ from those in production environments. See the Zero Auth in Sandbox page for more information.
