# HTTP status codes

The table below restores the general status reference from the original documentation. Each endpoint lists its documented responses.

## Allowed request types

- POST - Creates or updates a resource

- PUT - Updates a resource

- GET - Retrieves a resource or list of resources

- DELETE - Delete a resource

## Response status codes

| Status | Meaning | What to check |
| --- | --- | --- |
| `200` | OK | Check response body for errors |
| `201` | Created | Check response body for errors |
| `204` | No Content | Response for delete request |
| `400` | Bad Request | The request could not be processed because it contains missing or invalid information (such as validation error on an filter field, a missing required value) |
| `401` | Unauthorized | Disabled API feature or invalid connection credentials. |
| `402` | Payment Required | Check [web interface](https://app.datamolino.com/en/auth/users/sign_in) for billing info, billing action may be required |
| `403` | Forbidden | You have no access to resource |
| `404` | Not Found | Check request URL and HTTP method or agenda/document is not available, check response body for errors |
| `406` | Not Acceptable | Most probably malformed content type header or json body |
| `422` | Unprocessable Entity | The request was well-formed but was unable to be followed due to semantic or validation errors. |
| `429` | Too Many Requests | The request rate exceeded the applicable limit. Slow down and retry with backoff. Confirm your integration’s limit with Datamolino before sizing a bulk import. |
| `500` | Internal Server Error | The server encountered an unexpected condition which prevented it from fulfilling the request |
| `501` | Not Implemented | The server does not (currently) support the functionality required to fulfill the request |
| `502` | Bad Gateway | The server was acting as a gateway or proxy and received an invalid response from the upstream server. Check request parameters. |
| `503` | Service Unavailable | Overloaded API or scheduled maintenance in progress. Try again later. |
| `504` | Gateway Timeout | API request timeout |

## Handling errors

Inspect the response body as well as the HTTP status. A `204 No Content` response has no body. Use the endpoint’s request and response examples alongside this general reference.
