API Responses
The session API endpoints return responses in JSON format. Plivo sets anapi_id in each response to uniquely identify the request. Each API call returns one of these HTTP status codes depending on whether the call succeeds or fails:
| 200 | Request has been executed |
| 201 | Resource created |
| 202 | Resource changed |
| 204 | Resource deleted |
| 400 | A parameter is missing or is invalid |
| 401 | Authentication failed |
| 404 | Resource cannot be found |
| 405 | HTTP method not allowed |
| 429 | Too many requests, rate limited |
| 500 | Server error |
