apps.permissions.request

Allows an app to request additional scopes

Facts

Method URL: https://slack.com/api/apps.permissions.request

Preferred HTTP method: GET

Accepted content types: application/x-www-form-urlencoded

Rate limiting: Tier 2

Works with:

Token type	Required scope(s)
workspace	No scope required

Developer preview

This feature only applies to the workspace token-based Slack app developer preview, currently under active development.

This method is used to request additional permissions with a team. It's a part of the Permissions API made available to workspace token-based applications.

Arguments

Argument	Example	Required	Description
`token`	`xxxx-xxxxxxxxx-xxxx`	Required	Authentication token bearing required scopes.
`scopes`		Required	A comma separated list of scopes to request for
`trigger_id`		Required	Token used to trigger the permissions API

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 certain Events API events and other avenues. See Permissions API

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. Finally, if you don't use the Events API you can use apps.permissions.info to determine your app's current permission state.

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.

Error	Description
`invalid_trigger`	The provided `trigger_id` is invalid.
`trigger_exchanged`	The provided `trigger_id` has already been exchanged.
`invalid_scope`	Scopes are invalid.
`invalid_user`	There isn't a valid user to request permissions.
`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.
`org_login_required`	The workspace is undergoing an enterprise migration and will not be available until migration is complete.
`user_is_bot`	This method cannot be called by a bot user.
`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_array_arg`	The method was passed a PHP-style array argument (e.g. with a name like `foo[7]`). These are never valid with the Slack API.
`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/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.

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.
