Manage API clients

To interact with Zeebe in the cloud from the outside, every client application must authenticate itself. An OAuth Flow is therefore used for authentication:

auth-flow

The client configuration is shown at the bottom of the cluster detail view. Create a new client and all necessary information is displayed.

For the Client Id and Client Secret, a client application can request an access token at the authentication URL (steps 1 and 2). The access token is necessary to interact with Zeebe in the cloud (step 3).

note

Access tokens have a validity period that can be found in the access token. After this time, a new access token must be requested.

note

The auth service has a built-in rate limit. If too many token requests are executed in a short time, the client is blocked for a certain time. Since the access tokens have a certain validity period, they must be cached on the client side.

The officially offered client libraries (as well as the Node.js client) have already integrated with the auth routine, handle obtaining and refreshing an access token, and make use of a local cache.

Create a client​

To create a client, take the following steps:

  1. Navigate into the API tab.

cluster-details

  1. Click Create New Client to create a new client and name your client accordingly.

create-client

  1. Ensure you keep the generated client credentials in a safe place. The client secret will not be shown again. For your convenience, you can also download the client information to your computer.

created-client

The downloaded file contains all necessary information to communicate with your Zeebe instance in the future:

  • ZEEBE_ADDRESS: Address where your cluster can be reached.
  • ZEEBE_CLIENT_ID and ZEEBE_CLIENT_SECRET: Credentials to request a new access token.
  • ZEEBE_AUTHORIZATION_SERVER_URL: A new token can be requested at this address.
