Usage info

This Conversations API method invites 1-1000 users to a public or private channel. The calling user must be a member of the channel.

Partially failed calls

Users who can be successfully invited and who were not members of the workspace previously will not be invited if any of the user invites fail. Instead, an error response will be returned.

Inviting users who are in a "removed" state (that is, they were once a member of the workspace but have since been removed) will fail “silently”: an error response will be returned via the API, but all other users will be invited except for those in the "removed" state.

Common error response

Error response when users cannot be invited for differing reasons: one for not being associated with a valid user ID, and one for being the user sending the invite.

{
    "ok": false,
    "error": "user_not_found",
    "errors": [
        {
            "user": "U111111",
            "ok": false,
            "error": "user_not_found"
        },
        {
            "user": "U222222",
            "ok": false,
            "error": "cant_invite_self"
        }
    ]
}

Warnings

This table lists the expected warnings that this method will return. However, other warnings can be returned in the case where the service is experiencing unexpected trouble.

Warning	Description
`missing_charset`	The method was called via a `POST` request, and recommended practice for the specified `Content-Type` is to include a `charset` parameter. However, no `charset` was present. Specifically, non-form-data content types (e.g. `text/plain`) are the ones for which `charset` is recommended.
`superfluous_charset`	The method was called via a `POST` request, and the specified `Content-Type` is not defined to understand the `charset` parameter. However, `charset` was in fact present. Specifically, form-data content types (e.g. `multipart/form-data`) are the ones for which `charset` is superfluous.
