Provision and manage user accounts and groups with the Slack SCIM API. SCIM is used by Single Sign-On (SSO) services and identity providers to manage people across a variety of tools, including Slack. It's also possible to write your own apps and scripts using the SCIM API to programatically manage the members of your workspace.
Please note that the SCIM API is only available to Slack workspaces on the Plus plan and Slack Enterprise Grid.
SCIM is an API for managing the people on your team and the groups they belong to.
SCIM is an open standard supported by myriad services. It behaves slightly differently than other Slack APIs. For example, most of Slack's APIs can be described as "REST-like" but are, more accurately, actually RPC-style methods that use HTTP GET and POST interchangeably but no other verbs (such as PATCH or DELETE). SCIM, being a more proper REST API, expects HTTP verbs to be used in a specific manner.
While other APIs are for interacting with a Slack workspace directly, the SCIM APIs allow teams on the Plus and Enterprise Grid plans to administer the users on a workspace (or in an organization, in the case of Grid). If you've found yourself wishing for a set of users.admin.* endpoints, SCIM might be right for you.
Our SCIM implementation targets version 1.1 of the protocol.
Slack supports member provisioning via helper apps with supported identity providers. This document covers custom SCIM operations.
Be aware that it's possible to de-provision an entire workspace or Enterprise Grid organization with SCIM. Please test your scripts thoroughly before executing them. Of course, our support team is ready to assist you should you run into any trouble.
Like other Slack API's, the SCIM methods are accessed over that old standby protocol, HTTP.
Being a REST API, the HTTP verb (e.g. GET or POST or PATCH or even DELETE) used for each API method is important. Typically you will use GET to retrieve information, POST to create new objects, PUT and PATCH to modify objects, and DELETE to remove. (Alas, we seem to have lost our HEAD.)
The base URL for all calls to the SCIM API is https://api.slack.com/scim/v1/. All SCIM methods are branches of this base URL.
An OAuth token with the admin scope is required to access the SCIM API. The simplest way to acquire this token is for an admin on a Workspace to create a new Slack app, add the admin OAuth scope, install the app, and use the generated token. If you intend to build a Slack app for other teams to install, your app will need to properly handle the OAuth flow to generate the proper token.
The API token must be included via an Authorization header with a type of Bearer when calling any of the SCIM methods.
Provide a JSON request body for POST, PUT, and PATCH write operations, and set your HTTP Content-type header to application/json.
An example SCIM call might look like this:
GET /scim/v1/Users?count=1000 HTTP/1.1
Host: api.slack.com
Accept: application/json
Authorization: Bearer xoxp-4956040672-4956040692-6476208902-xxxxxx
On Plus, Slack Owners and Admins can generate a token to use the SCIM API. On Enterprise Grid, only Org Owners and Admins can use SCIM to modify users.
The token-generating account must remain an Admin or Owner in order to make SCIM updates.
One more note: the token generator can only action on accounts with the same or fewer permissions. For example, if an Admin account generates a SCIM token, they can take action on other Admins or members. They cannot take action on Owners.
On Enterprise Grid, SCIM operations work across the entire organization, not individual workspaces. A SCIM app can provision, de-provision, and update team members in just one place rather than having to do so across every workspace in an organization.
For this reason, the OAuth token used for calling SCIM API methods must be obtained from installing the app on the organization, not just a workspace within the organization. To get a SCIM app working on a grid organization, do the following:
admin scope and click the green Save Changes button.When installing the SCIM app, be sure to install it on your Grid organization, not a workspace within the organization.
Usergroups on Enterprise Grid work a bit differently as well. Creating SCIM groups will create an IDP group, which may or may not be the correct behavior depending on what you hope to accomplish.
The SCIM API is RESTful and the endpoint URLs are different than other Slack API endpoints.
GET /ServiceProviderConfigs Returns Slack's configuration details for our SCIM API, including which operations are supported.
Slack currently supports schemas for users and groups. Querying the schemas will provide the most up-to-date rendering of the supported SCIM attributes.
GET /Schemas/Users Returns Slack's configuration details for how users are formatted.
GET /Schemas/Groups Returns Slack's configuration details for how groups are formatted.
As you might expect, users map to the individuals of your team across a workspace or Grid organization. Each user contains properties called attributes, like userName and title. You can list users, filter by attribute, add new users, update a user's profile information, or remove a user entirely.
Attributes are the details associated with a user's account. These are the details that someone would typically set in their profile (for example, by clicking the Edit Profile button in the Slack application).
The following tables map SCIM attributes to the profile fields that Slack uses. Most of these profile fields are exposed directly in a person's profile in the Slack UI. Sometimes, mulitple SCIM attributes map to a single Slack profile field --- for example, Slack's Display name field will populate from either the displayName or the userName SCIM attribute, depending on which is set. If both are set, it will use displayName.
Note: when you sync some user attributes to Slack via SCIM, these fields become locked in Slack and you can no longer delete them or edit them. However, you may choose to hide them from user profiles.
Attribute values will vary by identity provider. For example, some may use a single field for a user's full name, others may provide sub-attributes such as givenName and familyName, still others may provide both. Either is acceptable, but they should only describe the same name (i.e. sub-attributes should not contain additional or optional information, such as a nickname).
Not every attribute will be displayed in a user's profile --- for example, active does not appear as a field but can be used to determine if a user's account is active.
The password attribute is never returned but can be used to set the initial password for a user if the team is not using an identity manager.

For methods that return a list --- GET /Users and GET /Groups --- it's possible to filter the list by the username, email, restricted, and ultra_restricted attributes, and return only the values matching that filter. The following rules apply:
The following is a list of valid operators:
| Operator | Description |
|---|---|
| eq | equal |
| co | contains |
| sw | starts with |
| pr | present value |
| gt | greater than |
| ge | greater than or equal |
| lt | less than |
| le | less than or equal |
| and | logical And |
| or | logical Or |
Attribute name and attribute operator are case insensitive. For example, the following two expressions will evaluate to the same logical value:
filter=userName Eq "Carly"
filter=username eq "carly"
Filters may be applied to the username and email user attributes, with the addition of two membership filters:
| Attribute Name | SCIM Attribute | Attribute Type |
|---|---|---|
| Multi-Channel-Guest | restricted |
Singular |
| Single-Channel-Guest | ultra_restricted |
Singular |
The following would return a list of all multi-channel guests of a workspace:
GET /scim/v1/Users?filter=restricted eq '1' HTTP/1.1
Host: api.slack.com
Accept: application/json
Authorization: Bearer xoxp-4956040672-4956040692-6476208902-xxxxxx
Occasionally, interacting with our APIs will result in an error instead of the result you're expecting. Slack will make every attempt to respond with a descriptive error message that will help you figure out what went wrong and how to fix it.
