OAuth
OAuth lets you create applications that can access Open Collective's API to read information and trigger changes on the platform.

  1. 1.
    Go to https://opencollective.com/{account}/admin/for-developers (replace {account} by the slug of the account you want to use as the owner of the app)
  2. 2.
    Click on + Create OAuth app and fill in the required information
  3. 3.
    On the success page, copy the client ID and secret for later use

Open Collective's OAuth implementation supports the standard authorization code grant type.
The web application flow to authorize users for your app is:
  1. 1.
    Users are redirected to request their Open Collective identity
  2. 2.
    Users are redirected back to your site by Open Collective with special code shared in the URL
  3. 3.
    You exchange the received code for an OAuth token

Name
Type
Description
client_id
string
Required. The client ID you copied after creating your app.
response_type
string
Required. Only supported value for now is code
redirect_uri
string
The URL in your application where users will be sent after authorization. If left out, Open Collective will redirect users to the callback URL configured in the OAuth Application settings. If provided, the redirect URL's host and port must exactly match the callback URL.
scope
string
A comma-separated list of scopes. If not provided, scope defaults to an empty list.
state
string
Use it to pass some state back to your application after redirecting and to protect against cross-site request forgery attacks (CSRF) by including an unguessable random string. See scopes below.

After users accept your request, they're redirected back to your site with a temporary code passed as an URL query parameter as well as the state you provided in the previous step. The temporary code will expire after 5 minutes. If the states don't match, then a third party created the request, and you should abort the process.
Otherwise, you can exchange the code you received as a parameter for an access token:

Parameter
Type
Description
grant_type
string
Required. The only supported value for now is authorization_code
client_id
string
Required. The client ID of your OAuth application (from Creating an OAuth App)
client_secret
string
Required. The client secret of you OAuth application (from Creating an OAuth App)
code
string
Required. The code you received as a response to Step 1, after the redirect)
redirect_uri
string
Required. The URL in your application where users are sent after authorization.

If the request succeeds, you'll receive an HTTP 200 response code with a JSON payload like:
{
"access_token": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
}
This access_token is what you want to use to access the API.

The access token allows you to make requests to the API on a behalf of a user on our public GraphQL API.
Authorization: Bearer {ACCESS_TOKEN}
GET https://opencollective.com/oauth/token
For example, in curl you can set the Authorization header like this:
curl 'https://opencollective.com/api/graphql/v2' \
-H 'authorization: Bearer {ACCESS_TOKEN}' \
-H 'content-type: application/json' \
-d '{"query": "{ me { id name email } }"}'

Scopes let you specify exactly what type of access you need. Scopes limit access for OAuth tokens. They do not grant any additional permission beyond that which the user already has.
When setting up an OAuth App on Open Collective, requested scopes are displayed to the user on the authorization form.
