# Update a Contact

> Update fields on an existing contact. Only send the fields you want to change. **Permission:** `contacts:update`



## OpenAPI

````yaml PUT /api/contacts/{clientId}
openapi: 3.0.0
info:
  title: Recepta Public API
  version: 1.0.0
  description: >-
    The Recepta API lets you programmatically manage calls, contacts, and SMS
    messages.


    Use this API to integrate Recepta with your own applications, CRMs, AI
    agents, or automation workflows.


    ## Authentication


    All endpoints require an API key passed in the `x-api-key` header.


    ```

    x-api-key: rcp_your_api_key_here

    ```


    Create and manage API keys in **Settings > API Keys** in the Recepta
    dashboard.


    ## Rate Limits


    Rate limits depend on your subscription plan:


    | Plan | Requests / Minute |

    |------|-------------------|

    | Free | 30 |

    | Starter | 60 |

    | Growth | 300 |

    | Enterprise | 1,000 |


    Every response includes rate limit headers:

    - `X-RateLimit-Limit` — maximum requests per window

    - `X-RateLimit-Remaining` — requests remaining

    - `X-RateLimit-Reset` — seconds until window resets


    When exceeded, you receive a `429 Too Many Requests` response with a
    `Retry-After` header.


    ## Pagination


    List endpoints support pagination via `page` and `limit` query parameters.
    Responses include a `pagination` object:


    ```json

    {
      "pagination": {
        "total": 142,
        "page": 1,
        "limit": 20,
        "totalPages": 8
      }
    }

    ```


    ## Errors


    All errors follow the same format:


    ```json

    {
      "success": false,
      "message": "Human-readable error description"
    }

    ```


    | Code | Meaning |

    |------|--------|

    | 400 | Bad Request — invalid or missing parameters |

    | 401 | Unauthorized — invalid or missing API key |

    | 403 | Forbidden — API key lacks required permission |

    | 404 | Not Found — resource does not exist |

    | 409 | Conflict — duplicate resource |

    | 429 | Rate Limited — too many requests |

    | 500 | Server Error — try again later |
