# Update Connection



## OpenAPI

````yaml /26.3/en/rest-api/openapi-v2.json put /v2/connections/{connection_id}
openapi: 3.0.3
info:
  title: CData Sync API
  description: >-
    REST API (v2) for CData Sync. The API lets you manage workspaces,
    connections, jobs, transformations, pipelines, and users, and to run and
    monitor data replication and transformation work.


    ## Base path

    All endpoints are served under the `/api.rsc` application path, e.g.
    `https://your-sync-host/api.rsc/v2/workspaces`.


    ## Authentication

    Requests are authenticated with an auth token passed in the
    `x-cdata-authtoken` header, or with HTTP Basic authentication using a Sync
    user's credentials. A token can be generated via `POST
    /v2/users/generate-token`.


    ## Response envelope

    Successful read/write responses return a JSON **array** of objects, even
    when a single resource is requested (the array then contains one element).
    `count` endpoints return an array containing a single `{ "count": <n> }`
    object. `DELETE` operations return `204 No Content`.


    ## Date/time format

    Date/time values are formatted as `yyyy-MM-dd'T'HH:mm:ssZZZ` (ISO-8601 with
    timezone offset). The format is also echoed in the `X-DateTime-Format`
    response header.


    ## Roles

    Most endpoints require the `cdata_user` role; workspace and user management
    endpoints require the `cdata_admin` role.
