OAuth Token Generation

You can generate an OAuth token for Primavera Administration REST API using the Resource Owner Password Credentials (ROPC) grant type. ROPC uses the resource owner's password credentials (user name and password) as an authorization grant to obtain an OAuth access token. This grant type is suitable for users who authenticate against IDCS directly.

After an OAuth token is generated, it can be passed to Primavera Administration REST API. See Authentication and Authorization (OAuth)
