Authentication

Authentication in the cloud

To access the API endpoint, you need an access token.

Your client must send a header in each request:

Authorization: Bearer <Token>

For example, send a request using curl:

curl -X POST -H -H :accept: application/json" -H "Authorization: Bearer <TOKEN>" -d '' http://localhost:8080/v1/tasks/search

How to obtain the access token

You must obtain a token to use the Tasklist API. When you create a Tasklist client, you get all the information needed to connect to Tasklist.

See our guide on building your own client.

The following settings are needed:

Name	Description	Default value
client id	Name of your registered client	-
client secret	Password for your registered client	-
audience	Permission name; if not given use default value	tasklist.camunda.io
authorization server url	Token issuer server	-

Send a token issue POST request to the authorization server with the following content:

{
  "client_id": "<client-id>",
  "client_secret": "<client-secret>",
  "audience": "<audience>",
  "grant_type": "client_credentials"
}

See the following example with curl:

curl -X POST --header 'content-type: application/json' --data '{"client_id": "<client-id>", "client_secret":"<client-secret>","audience":"<audience>","grant_type":"client_credentials"}' https://<authorization server url>

If the authorization is successful, the authorization server sends back the access token, when it expires, scope, and type:

{
  "access_token": "ey...",
  "scope": "...",
  "expires_in": 86400,
  "token_type": "Bearer"
}

Authentication for Self-Managed cluster

The authentication is described in Tasklist Configuration - Authentication.
