Prerequisites

To install and authenticate the app, you need to provide the following input: 

  1. Config Name - The config name is the unique identifier which one needs to provide for the configuration added to the app

  2. Private Key

  3. Private Key Id

  4. Client Email


Step 1: Create a Service Account

Set up a Service Account project in the Google API Console.

  1. Create a new project (or select an existing one)


  1. Click on Create service account.

  1. Under Service account details, type a name, ID, and description for the service account, then click Create.

  1. Under Service account permissions, select the IAM roles as 'Project Owner' to grant to the service account, then click Continue.

  1. Optional: Under Grant users access to this service account, add the users or groups that are allowed to use and manage the service account.

  1. Make sure the key type is set to JSON and click Create.

  1. Click Close > Save.

  1. Save the downloaded JSON key.

Your new public/private key pair is generated and downloaded to your machine; it serves as the only copy of the private key. You are responsible for storing it securely. If you lose this key pair, you will need to generate a new one.

Note: The Client Email, Private Key and Private Key Id used as app installation input are obtained from the Service account JSON file downloaded. So one needs to copy these parameters from the downloaded JSON file and give the app input as shown below.

  1. Under Domain-wide delegation, click Manage Domain Wide Delegation.



  1. On the Manage domain-wide delegation page, click Add new.



  1. Enter the client ID of the service account or OAuth2 client ID of the app.
