AlmondPay uses conventional HTTP response codes to indicate the success or failure of an API request. In general: Codes in the 2xx range indicate success. Codes in the 4xx range indicate an error that failed given the information provided (e.g., a required parameter was omitted, a charge failed, etc.). Codes in the 5xx range indicate an error with AlmondPay's servers (these are rare).
| Code | Description |
|---|---|
| 200 - OK | Everything worked as expected |
| 400 - Bad Request | The request was unacceptable, often due to missing a required parameter. |
| 401 - Unauthorized | No valid API key (access token) was provided. |
| 403 - Forbidden | The API key doesn't have permission to perform the request. |
| 404 - Not Found | The requested resource doesn't exist. |
| 429 - Too Many Request | Too many requests hit the API too quickly. |
| 500, 502, 503, 504 - Server Errors | Something went wrong on AlmondPay's end. These are rare and if they happen, please contact us immediately. |
