Developer preview has ended

This feature was exclusive to our workspace apps developer preview. The preview has now ended, but fan-favorite features such as token rotation and the Conversations API will become available to classic Slack apps over the coming months.

This method is used to request additional permissions from a user on a workspace.

It's part of the Permissions API that is available only to workspace apps.

To list currently awarded user-centric permissions, use apps.permissions.users.list.

Arguments

Argument Example Required Description
tokenxxxx-xxxxxxxxx-xxxxRequired

Authentication token bearing required scopes.

scopes Required

A comma separated list of user scopes to request for

trigger_id Required

Token used to trigger the request

user Required

The user this scope is being requested for

Present arguments as parameters in application/x-www-form-urlencoded querystring or POST body. This method does not currently accept application/json.

The trigger_id parameter is required and can be found attached to some Events API events, interactive framework action URL invocations, dialog submissions, and other ways we send your app timely, user-initiated data. See these docs about the Permissions API and triggers to learn more.

Response

Standard success response when used with a user token

{
    "ok": true
}

Standard failure response when trigger_id is invalid

{
    "ok": false,
    "error": "invalid_trigger_id"
}

A response other than "ok": true indicates the permission request was not presented to the user, perhaps due to an invalid or expired trigger_id.

You'll receive related app events if the user approves or rejects your permissions request. If the user does nothing, no event will emit.

Errors

This table lists the expected errors that this method could return. However, other errors can be returned in the case where the service is down or other unexpected factors affect processing. Callers should always check the value of the ok params in the response.

ErrorDescription
trigger_exchanged

The provided trigger_id has already been exchanged.

invalid_user

There isn't a valid user to request permissions.

invalid_scope

Scopes are invalid.

invalid_trigger

The provided trigger_id is invalid.

not_authed

No authentication token provided.

invalid_auth

Some aspect of authentication cannot be validated. Either the provided token is invalid or the request originates from an IP address disallowed from making the request.

account_inactive

Authentication token is for a deleted user or workspace.

token_revoked

Authentication token is for a deleted user or workspace or the app has been removed.

no_permission

The workspace token used in this request does not have the permissions necessary to complete the request. Make sure your app is a member of the conversation it's attempting to post a message to.

org_login_required

The workspace is undergoing an enterprise migration and will not be available until migration is complete.

ekm_access_denied

Administrators have suspended the ability to post a message.

missing_scope

The token used is not granted the specific scope permissions required to complete this request.

is_bot

This method cannot be called by a bot user.

invalid_arguments

The method was called with invalid arguments.

invalid_arg_name

The method was passed an argument whose name falls outside the bounds of accepted or expected values. This includes very long names and names with non-alphanumeric characters other than _. If you get this error, it is typically an indication that you have made a very malformed API call.

invalid_charset

The method was called via a POST request, but the charset specified in the Content-Type header was invalid. Valid charset names are: utf-8 iso-8859-1.

invalid_form_data

The method was called via a POST request with Content-Type application/x-www-form-urlencoded or multipart/form-data, but the form data was either missing or syntactically invalid.

invalid_post_type

The method was called via a POST request, but the specified Content-Type was invalid. Valid types are: application/json application/x-www-form-urlencoded multipart/form-data text/plain.

missing_post_type

The method was called via a POST request and included a data payload, but the request did not include a Content-Type header.

team_added_to_org

The workspace associated with your request is currently undergoing migration to an Enterprise Organization. Web API and other platform operations will be intermittently unavailable until the transition is complete.

request_timeout

The method was called via a POST request, but the POST data was either missing or truncated.

fatal_error

The server could not complete your operation(s) without encountering a catastrophic error. It's possible some aspect of the operation succeeded before the error was raised.

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.

WarningDescription
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.
