# OAuth 2.0 identity provider API **(FREE)**
2015-01-12 23:30:34 +00:00
2021-09-23 22:34:10 +00:00
GitLab provides an API to allow third-party services to access GitLab resources on a user's behalf
with the [OAuth2 ](https://oauth.net/2/ ) protocol.
2015-01-12 23:30:34 +00:00
2021-09-23 22:34:10 +00:00
To configure GitLab for this, see
[Configure GitLab as an OAuth 2.0 authentication identity provider ](../integration/oauth_provider.md ).
This functionality is based on the [doorkeeper Ruby gem ](https://github.com/doorkeeper-gem/doorkeeper ).

## Supported OAuth 2.0 flows
2015-01-12 23:30:34 +00:00
2021-08-27 00:08:45 +00:00
GitLab supports the following authorization flows:
2015-01-12 23:30:34 +00:00
2021-01-07 21:10:18 +00:00
- **Authorization code with [Proof Key for Code Exchange (PKCE) ](https://tools.ietf.org/html/rfc7636 ):**
2020-12-22 21:10:06 +00:00
Most secure. Without PKCE, you'd have to include client secrets on mobile clients,
2021-01-23 00:08:46 +00:00
and is recommended for both client and server apps.
2021-01-07 21:10:18 +00:00
- **Authorization code:** Secure and common flow. Recommended option for secure
2020-12-22 21:10:06 +00:00
server-side apps.
2021-01-07 21:10:18 +00:00
- **Implicit grant:** Originally designed for user-agent only apps, such as
2021-09-23 22:34:10 +00:00
single page web apps running on GitLab Pages.
2021-08-27 00:08:45 +00:00
The [Internet Engineering Task Force (IETF) ](https://tools.ietf.org/html/draft-ietf-oauth-security-topics-09#section-2.1.2 )
2020-12-22 21:10:06 +00:00
recommends against Implicit grant flow.
- **Resource owner password credentials:** To be used **only** for securely
hosted, first-party services. GitLab recommends against use of this flow.
The draft specification for [OAuth 2.1 ](https://oauth.net/2.1/ ) specifically omits both the
2021-08-27 00:08:45 +00:00
Implicit grant and Resource Owner Password Credentials flows. It will be deprecated in the next OAuth specification version.
2015-01-12 23:30:34 +00:00
2019-01-14 03:46:01 +00:00
Refer to the [OAuth RFC ](https://tools.ietf.org/html/rfc6749 ) to find out
how all those flows work and pick the right one for your use case.
2016-08-04 13:25:37 +00:00
2020-12-22 21:10:06 +00:00
Both **authorization code** (with or without PKCE) and **implicit grant** flows require `application` to be
2019-01-14 03:46:01 +00:00
registered first via the `/profile/applications` page in your user's account.
During registration, by enabling proper scopes, you can limit the range of
2021-04-25 21:09:26 +00:00
resources which the `application` can access. Upon creation, you obtain the
2019-01-14 03:46:01 +00:00
`application` credentials: _Application ID_ and _Client Secret_ - **keep them secure** .
2015-01-12 23:30:34 +00:00
2020-10-23 15:08:42 +00:00
### Prevent CSRF attacks
To [protect redirect-based flows ](https://tools.ietf.org/id/draft-ietf-oauth-security-topics-13.html#rec_redirect ),
the OAuth specification recommends the use of "One-time use CSRF tokens carried in the state
parameter, which are securely bound to the user agent", with each request to the
2020-11-16 21:09:02 +00:00
`/oauth/authorize` endpoint. This can prevent
2020-10-23 15:08:42 +00:00
[CSRF attacks ](https://wiki.owasp.org/index.php/Cross-Site_Request_Forgery_(CSRF )).
### Use HTTPS in production
For production, please use HTTPS for your `redirect_uri` .
For development, GitLab allows insecure HTTP redirect URIs.
2021-08-27 00:08:45 +00:00
As OAuth 2.0 bases its security entirely on the transport layer, you should not use unprotected
2020-10-23 15:08:42 +00:00
URIs. For more information, see the [OAuth 2.0 RFC ](https://tools.ietf.org/html/rfc6749#section-3.1.2.1 )
2020-11-16 21:09:02 +00:00
and the [OAuth 2.0 Threat Model RFC ](https://tools.ietf.org/html/rfc6819#section-4.4.2.1 ).
2020-10-23 15:08:42 +00:00
These factors are particularly important when using the
[Implicit grant flow ](#implicit-grant-flow ), where actual credentials are included in the `redirect_uri` .
2016-08-04 13:25:37 +00:00
2021-04-25 21:09:26 +00:00
In the following sections you can find detailed instructions on how to obtain
2019-01-14 03:46:01 +00:00
authorization with each flow.
2015-01-12 23:30:34 +00:00
2020-12-22 21:10:06 +00:00
### Authorization code with Proof Key for Code Exchange (PKCE)
The [PKCE RFC ](https://tools.ietf.org/html/rfc7636#section-1.1 ) includes a
detailed flow description, from authorization request through access token.
The following steps describe our implementation of the flow.
The Authorization code with PKCE flow, PKCE for short, makes it possible to securely perform
the OAuth exchange of client credentials for access tokens on public clients.
Before starting the flow, generate the `STATE` , the `CODE_VERIFIER` and the `CODE_CHALLENGE` .
- The `STATE` a value that can't be predicted used by the client to maintain
state between the request and callback. It should also be used as a CSRF token.
- The `CODE_VERIFIER` is a random string, between 43 and 128 characters in length,
which use the characters `A-Z` , `a-z` , `0-9` , `-` , `.` , `_` , and `~` .
- The `CODE_CHALLENGE` is an URL-safe base64-encoded string of the SHA256 hash of the
`CODE_VERIFIER`
2021-09-07 06:11:06 +00:00
- The SHA256 hash must be in binary format before encoding.
2021-07-29 00:09:04 +00:00
- In Ruby, you can set that up with `Base64.urlsafe_encode64(Digest::SHA256.digest(CODE_VERIFIER), padding: false)` .
2021-09-07 21:10:59 +00:00
- For reference, a `CODE_VERIFIER` string of `ks02i3jdikdo2k0dkfodf3m39rjfjsdk0wk349rj3jrhf` when hashed
and encoded using the Ruby snippet above produces a `CODE_CHALLENGE` string
2021-09-07 06:11:06 +00:00
of `2i0WFA-0AerkjQm4X4oDEhqA17QIAKNjXpagHBXmO_U` .
2020-12-22 21:10:06 +00:00
1. Request authorization code. To do that, you should redirect the user to the
`/oauth/authorize` page with the following query parameters:
```plaintext
2021-01-22 03:09:04 +00:00
https://gitlab.example.com/oauth/authorize?client_id=APP_ID& redirect_uri=REDIRECT_URI& response_type=code& state=STATE& scope=REQUESTED_SCOPES& code_challenge=CODE_CHALLENGE& code_challenge_method=S256
2020-12-22 21:10:06 +00:00
```
This page asks the user to approve the request from the app to access their
account based on the scopes specified in `REQUESTED_SCOPES` . The user is then
redirected back to the specified `REDIRECT_URI` . The [scope parameter ](https://github.com/doorkeeper-gem/doorkeeper/wiki/Using-Scopes#requesting-particular-scopes )
is a space separated list of scopes associated with the user.
For example,`scope=read_user+profile` requests the `read_user` and `profile` scopes.
The redirect includes the authorization `code` , for example:
```plaintext
2021-01-22 03:09:04 +00:00
https://example.com/oauth/redirect?code=1234567890& state=STATE
2020-12-22 21:10:06 +00:00
```
1. With the authorization `code` returned from the previous request (denoted as
`RETURNED_CODE` in the following example), you can request an `access_token` , with
any HTTP client. The following example uses Ruby's `rest-client` :
```ruby
parameters = 'client_id=APP_ID& client_secret=APP_SECRET& code=RETURNED_CODE& grant_type=authorization_code& redirect_uri=REDIRECT_URI& code_verifier=CODE_VERIFIER'
RestClient.post 'https://gitlab.example.com/oauth/token', parameters
```
Example response:
```json
{
"access_token": "de6780bc506a0446309bd9362820ba8aed28aa506c71eedbe1c5c4f9dd350e54",
"token_type": "bearer",
"expires_in": 7200,
"refresh_token": "8257e65c97202ed1726cf9571600918f3bffb2544b26e00a61df9897668c33a1",
"created_at": 1607635748
}
```
2021-08-27 00:08:45 +00:00
2021-08-13 06:10:15 +00:00
1. To retrieve a new `access_token` , use the `refresh_token` parameter. Refresh tokens may
be used even after the `access_token` itself expires. This request:
- Invalidates the existing `access_token` and `refresh_token` .
- Sends new tokens in the response.
```ruby
parameters = 'client_id=APP_ID& client_secret=APP_SECRET& refresh_token=REFRESH_TOKEN& grant_type=refresh_token& redirect_uri=REDIRECT_URI& code_verifier=CODE_VERIFIER'
RestClient.post 'https://gitlab.example.com/oauth/token', parameters
```
Example response:
2021-09-07 21:10:59 +00:00
2021-08-13 06:10:15 +00:00
```json
{
"access_token": "c97d1fe52119f38c7f67f0a14db68d60caa35ddc86fd12401718b649dcfa9c68",
"token_type": "bearer",
"expires_in": 7200,
"refresh_token": "803c1fd487fec35562c205dac93e9d8e08f9d3652a24079d704df3039df1158f",
"created_at": 1628711391
}
```
2020-12-22 21:10:06 +00:00
NOTE:
The `redirect_uri` must match the `redirect_uri` used in the original
authorization request.
You can now make requests to the API with the access token.
### Authorization code flow
2015-01-12 23:30:34 +00:00
2020-12-04 21:09:29 +00:00
NOTE:
2019-01-14 03:46:01 +00:00
Check the [RFC spec ](https://tools.ietf.org/html/rfc6749#section-4.1 ) for a
detailed flow description.
2016-08-04 13:25:37 +00:00
2020-12-22 21:10:06 +00:00
The authorization code flow is essentially the same as
[authorization code flow with PKCE ](#authorization-code-with-proof-key-for-code-exchange-pkce ),
2015-01-12 23:30:34 +00:00
2021-01-22 03:09:04 +00:00
Before starting the flow, generate the `STATE` . It is a value that can't be predicted
used by the client to maintain state between the request and callback. It should also
be used as a CSRF token.
2019-01-14 03:46:01 +00:00
1. Request authorization code. To do that, you should redirect the user to the
2021-01-22 03:09:04 +00:00
`/oauth/authorize` page with the following query parameters:
2015-01-12 23:30:34 +00:00
2020-03-06 03:08:08 +00:00
```plaintext
2020-12-22 21:10:06 +00:00
https://gitlab.example.com/oauth/authorize?client_id=APP_ID& redirect_uri=REDIRECT_URI& response_type=code& state=STATE& scope=REQUESTED_SCOPES
2019-01-14 03:46:01 +00:00
```
2016-08-04 13:25:37 +00:00

2015-01-12 23:30:34 +00:00
You can now make requests to the API with the access token returned.
2019-01-14 03:46:01 +00:00
### Implicit grant flow
2015-01-12 23:30:34 +00:00
2020-12-04 21:09:29 +00:00
NOTE:
2021-01-07 21:10:18 +00:00
For a detailed flow diagram, see the [RFC specification ](https://tools.ietf.org/html/rfc6749#section-4.2 ).
2018-11-13 06:07:16 +00:00
2020-12-04 21:09:29 +00:00
WARNING:
2021-05-19 15:10:40 +00:00
Implicit grant flow is inherently insecure and the IETF has removed it in [OAuth 2.1 ](https://oauth.net/2.1/ ).
For this reason, [support for it is deprecated ](https://gitlab.com/gitlab-org/gitlab/-/issues/288516 ).
In GitLab 14.0, new applications can't be created using it. In GitLab 14.4, support for it is
scheduled to be removed for existing applications.
2020-12-22 21:10:06 +00:00
We recommend that you use [Authorization code with PKCE ](#authorization-code-with-proof-key-for-code-exchange-pkce ) instead. If you choose to use Implicit flow, be sure to verify the
`application id` (or `client_id` ) associated with the access token before granting
2021-08-27 00:08:45 +00:00
access to the data. To learn more, read
[Retrieving the token information ](#retrieve-the-token-information )).
2020-12-22 21:10:06 +00:00
Unlike the authorization code flow, the client receives an `access token`
2021-08-27 00:08:45 +00:00
immediately as a result of the authorization request. The flow does not use the
client secret or the authorization code, as the application
code and storage is accessible on client browsers and mobile devices.
2017-07-07 14:52:45 +00:00
2019-01-14 03:46:01 +00:00
To request the access token, you should redirect the user to the
`/oauth/authorize` endpoint using `token` response type:
2015-01-12 23:30:34 +00:00
2020-02-28 00:09:08 +00:00
```plaintext
2019-07-27 00:28:19 +00:00
https://gitlab.example.com/oauth/authorize?client_id=APP_ID& redirect_uri=REDIRECT_URI& response_type=token& state=YOUR_UNIQUE_STATE_HASH& scope=REQUESTED_SCOPES
2015-01-12 23:30:34 +00:00
```
2021-04-25 21:09:26 +00:00
This prompts the user to approve the applications access to their account
2019-07-27 00:28:19 +00:00
based on the scopes specified in `REQUESTED_SCOPES` and then redirect back to
the `REDIRECT_URI` you provided. The [scope parameter ](https://github.com/doorkeeper-gem/doorkeeper/wiki/Using-Scopes#requesting-particular-scopes )
2021-07-16 21:09:41 +00:00
is a space separated list of scopes you want to have access to (for example, `scope=read_user+profile`
2019-07-27 00:28:19 +00:00
would request `read_user` and `profile` scopes). The redirect
2021-04-25 21:09:26 +00:00
includes a fragment with `access_token` as well as token details in GET
2019-01-14 03:46:01 +00:00
parameters, for example:
2015-01-12 23:30:34 +00:00
2020-02-28 00:09:08 +00:00
```plaintext
2020-08-21 18:10:24 +00:00
https://example.com/oauth/redirect#access_token=ABCDExyz123& state=YOUR_UNIQUE_STATE_HASH& token_type=bearer& expires_in=3600
2015-01-12 23:30:34 +00:00
```
2019-01-14 03:46:01 +00:00
### Resource owner password credentials flow
2015-01-12 23:30:34 +00:00
2020-12-04 21:09:29 +00:00
NOTE:
2019-01-14 03:46:01 +00:00
Check the [RFC spec ](https://tools.ietf.org/html/rfc6749#section-4.3 ) for a
detailed flow description.
2016-06-21 05:33:50 +00:00
2020-12-04 21:09:29 +00:00
NOTE:
2019-01-14 03:46:01 +00:00
The Resource Owner Password Credentials is disabled for users with [two-factor
authentication](../user/profile/account/two_factor_authentication.md) turned on.
These users can access the API using [personal access tokens ](../user/profile/personal_access_tokens.md )
instead.
2016-06-21 05:33:50 +00:00
2019-01-14 03:46:01 +00:00
In this flow, a token is requested in exchange for the resource owner credentials
(username and password).
2015-01-12 23:30:34 +00:00
2019-01-14 03:46:01 +00:00
The credentials should only be used when:
2016-08-04 13:25:37 +00:00
2019-01-14 03:46:01 +00:00
- There is a high degree of trust between the resource owner and the client. For
example, the client is part of the device operating system or a highly
privileged application.
- Other authorization grant types are not available (such as an authorization code).

2019-01-14 03:46:01 +00:00
Never store the user's credentials and only use this grant type when your client
is deployed to a trusted environment, in 99% of cases
[personal access tokens ](../user/profile/personal_access_tokens.md ) are a better
choice.
2017-07-07 14:52:45 +00:00
2019-01-14 03:46:01 +00:00
Even though this grant type requires direct client access to the resource owner
credentials, the resource owner credentials are used for a single request and
are exchanged for an access token. This grant type can eliminate the need for
the client to store the resource owner credentials for future use, by exchanging
the credentials with a long-lived access token or refresh token.
2015-01-12 23:30:34 +00:00
2019-01-14 03:46:01 +00:00
To request an access token, you must make a POST request to `/oauth/token` with
the following parameters:
```json
2015-01-12 23:30:34 +00:00
{
"grant_type" : "password",
"username" : "user@example.com",
2016-09-28 08:41:39 +00:00
"password" : "secret"
2015-01-12 23:30:34 +00:00
}
```
2019-01-14 03:46:01 +00:00
Example cURL request:
2021-03-10 12:09:14 +00:00
```shell
echo 'grant_type=password& username=< your_username > & password=< your_password > ' > auth.txt
curl --data "@auth.txt" --request POST "https://gitlab.example.com/oauth/token"
```
You can also use this grant flow with registered OAuth applications, by using
HTTP Basic Authentication with the application's `client_id` and `client_secret` :
2020-01-30 15:09:15 +00:00
```shell
2019-01-14 03:46:01 +00:00
echo 'grant_type=password& username=< your_username > & password=< your_password > ' > auth.txt
2021-06-02 15:09:59 +00:00
curl --data "@auth.txt" --user client_id:client_secret \
--request POST "https://gitlab.example.com/oauth/token"
2019-01-14 03:46:01 +00:00
```
2021-04-25 21:09:26 +00:00
Then, you receive a response containing the access token:
2015-01-12 23:30:34 +00:00
2020-02-28 00:09:08 +00:00
```json
2015-01-12 23:30:34 +00:00
{
"access_token": "1f0af717251950dbd4d73154fdf0a474a5c5119adad999683f5b450c460726aa",
"token_type": "bearer",
"expires_in": 7200
}
```
2020-05-28 21:08:22 +00:00
By default, the scope of the access token is `api` , which provides complete read/write access.
2019-01-14 03:46:01 +00:00
For testing, you can use the `oauth2` Ruby gem:
2015-01-12 23:30:34 +00:00
2020-02-28 00:09:08 +00:00
```ruby
2020-08-21 18:10:24 +00:00
client = OAuth2::Client.new('the_client_id', 'the_client_secret', :site => "https://example.com")
2016-09-28 08:41:39 +00:00
access_token = client.password.get_token('user@example.com', 'secret')
2015-01-12 23:30:34 +00:00
puts access_token.token
2015-02-03 23:18:40 +00:00
```

## Access GitLab API with `access token`
2017-07-07 14:52:45 +00:00
2019-01-14 03:46:01 +00:00
The `access token` allows you to make requests to the API on behalf of a user.
You can pass the token either as GET parameter:
2020-02-28 00:09:08 +00:00
```plaintext
2017-07-07 14:52:45 +00:00
GET https://gitlab.example.com/api/v4/user?access_token=OAUTH-TOKEN
```
or you can put the token to the Authorization header:
2020-02-28 00:09:08 +00:00
```shell
2020-05-28 00:08:37 +00:00
curl --header "Authorization: Bearer OAUTH-TOKEN" "https://gitlab.example.com/api/v4/user"
2017-07-07 14:52:45 +00:00
```
2020-02-18 03:08:54 +00:00
2021-08-27 00:08:45 +00:00
## Retrieve the token information
2020-02-18 03:08:54 +00:00
2021-08-27 00:08:45 +00:00
To verify the details of a token, use the `token/info` endpoint provided by the
Doorkeeper gem. For more information, see
[`/oauth/token/info` ](https://github.com/doorkeeper-gem/doorkeeper/wiki/API-endpoint-descriptions-and-examples#get----oauthtokeninfo ).
2020-02-18 03:08:54 +00:00
2020-02-19 03:08:47 +00:00
You must supply the access token, either:
2020-02-18 03:08:54 +00:00
2020-02-19 03:08:47 +00:00
- As a parameter:
2020-02-18 03:08:54 +00:00
2020-02-28 00:09:08 +00:00
```plaintext
2020-02-19 03:08:47 +00:00
GET https://gitlab.example.com/oauth/token/info?access_token=< OAUTH-TOKEN >
```
2020-02-18 03:08:54 +00:00
2020-02-19 03:08:47 +00:00
- In the Authorization header:
2020-02-18 03:08:54 +00:00
2020-02-19 03:08:47 +00:00
```shell
2020-05-28 00:08:37 +00:00
curl --header "Authorization: Bearer < OAUTH-TOKEN > " "https://gitlab.example.com/oauth/token/info"
2020-02-19 03:08:47 +00:00
```
The following is an example response:
2020-02-18 03:08:54 +00:00
```json
{
"resource_owner_id": 1,
"scope": ["api"],
"expires_in": null,
"application": {"uid": "1cb242f495280beb4291e64bee2a17f330902e499882fe8e1e2aa875519cab33"},
"created_at": 1575890427
}
```
2020-02-19 03:08:47 +00:00
### Deprecated fields
The fields `scopes` and `expires_in_seconds` are included in the response.
These are aliases for `scope` and `expires_in` respectively, and have been included to
prevent breaking changes introduced in [doorkeeper 5.0.2 ](https://github.com/doorkeeper-gem/doorkeeper/wiki/Migration-from-old-versions#from-4x-to-5x ).
2021-04-25 21:09:26 +00:00
Don't rely on these fields as they are slated for removal in a later release.
2021-03-09 21:09:15 +00:00
2021-09-22 00:09:28 +00:00
## Revoke a token
To revoke a token, use the `revoke` endpoint. The API returns a 200 response code and an empty
JSON hash to indicate success.
```ruby
parameters = 'client_id=APP_ID& client_secret=APP_SECRET& token=TOKEN'
RestClient.post 'https://gitlab.example.com/oauth/revoke', parameters
```

## OAuth 2.0 tokens and GitLab registries
2021-03-09 21:09:15 +00:00
2021-08-27 00:08:45 +00:00
Standard OAuth 2.0 tokens support different degrees of access to GitLab
registries, as they:
2021-03-09 21:09:15 +00:00
- Do not allow users to authenticate to:
- The GitLab [Container registry ](../user/packages/container_registry/index.md#authenticate-with-the-container-registry ).
- Packages listed in the GitLab [Package registry ](../user/packages/package_registry/index.md ).
- Allow users to get, list, and delete registries through
the [Container registry API ](container_registry.md ).
