apps.permissions.request

Allows an app to request additional scopes

Supported token types:

workspace

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

This method has the URL https://slack.com/api/apps.permissions.request and follows the Slack Web API calling conventions.

Present these parameters as part of an application/x-www-form-urlencoded querystring or POST body. application/json is not currently accepted.

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

The trigger_id parameter is required and can be found attached to certain Events API events and other avenues. See Permissions API

Response

{
    "ok": true
}

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_id`	Trigger id is not valid.
`invalid_scope`	Scopes are invalid.
`invalid_user`	There isn't a valid user to request permissions.
`not_authed`	No authentication token provided.
`invalid_auth`	Invalid authentication token.
`account_inactive`	Authentication token is for a deleted user or workspace.
`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.

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.
