# Payment Error Codes

Zotlo standardizes all payment provider responses into a unified set of status and error codes.\
This ensures consistent behavior across different PSPs, easier debugging, and reliable handling of edge cases.

Each payment attempt returns one of the codes below.

## Success Code

<table><thead><tr><th width="174.828125">Code</th><th>Meaning</th></tr></thead><tbody><tr><td>S0000001</td><td>Payment completed successfully.</td></tr></tbody></table>

## Error Codes

Below is the full list of error codes returned by Zotlo.

{% hint style="info" %}
**Note:**

All error codes starting with E indicate a *recoverable* payment failure.

Codes starting with F indicate *fatal* failures where the user must contact support or retry later.
