Obtaining and Using an OAuth Token for Platform Services

The OAuth 2.0 token service provided by Oracle Identity Cloud Service is a mechanism that enables you to use a secured token to access the REST endpoints of Oracle Cloud Platform Services (PaaS).

An OAuth access token has an expiration value of 86,400 seconds (24 hours). If you want to make REST API requests 24 hours after getting an access token, you need to obtain a new token.

Note:

  • The following procedure is only applicable to Oracle Cloud accounts that were created after 18.1.4.

  • To access a cloud platform service that is integrated with Oracle Identity Cloud Service, the identity domain ID is the Oracle Identity Cloud Service tenant name. This tenant name begins with the characters idcs- followed by a string of numbers and letters (for example, idcs-9a888b7e6ebb44b4b65). See Find Your Oracle Identity Cloud Service Tenant Name.

  • cURL examples are used in the procedure to obtain an access token from Oracle Identity Cloud Service, and then access a cloud platform service REST endpoint with the token.

What You Need

Get the following information from the Oracle Identity Cloud Service web console.

  • Oracle Identity Cloud Service instance URL
  • Client ID
  • Client secret
  • Primary audience URL
  • Allowed scope

  1. Sign in to the My Services dashboard for your Oracle Identity Cloud Service tenant name.

    Note:

    You need to have either the Identity Domain Administrator role or PaaS Administrator role to follow the steps in this procedure.

  2. In the list of services, locate the entry for Oracle Identity Cloud Service, and then click Identity Cloud.

  3. On the Overview tab, locate the Service Instances section, and then copy the value shown in the Service Instance URL field.

    For example: https://idcs-9a888b7e6ebb44b4b65.identity.oraclecloud.com/ui/v1/adminconsole

    Where idcs-9a888b7e6ebb44b4b65.identity.oraclecloud.com is the REST server portion of the Oracle Identity Cloud Service Instance URL (which forms part of the endpoint URL for requesting an access token).

  4. Click Open Service Console, expand the Navigation Drawer, and then click Applications.

  5. In the search field, enter PSM and then click the search icon. In the results, locate the entry titled PSM App for API OAuth support.

    Note:

    The Platform Service Manager App (PSMApp) is not available for Oracle Cloud accounts that were created before 18.1.4.

  6. Click the name of the application titled PSM App for API OAuth support. The name has the form PSMApp-cacct-string-of-letters-and-numbers.

    For example:

    PSMApp-cacct-9z8x7c6v5b4n3m

    This is the Oracle Identity Cloud Service trusted PSM client application, which is automatically created for Oracle Cloud accounts (after 18.1.4) and associated with the Oracle Cloud Platform Service.

  7. Click Configuration. Under General Information, copy the value shown in the Client ID field.

    This is the PSMApp client ID. For example:

    PSMApp-cacct-9z8x7c6v5b4n3m_APPID

  8. Click Show Secret, and then copy the value.

    This is the PSMApp client secret. For example:

    c53b437-1768-4cb6-911e-1e6eg2g3543

  9. Expand Resources. Copy the value shown in the Primary Audience field.

    This is the PSMApp primary audience URL. For example:

    https://psm-cacct-9z8x7c6v5b4n3m.console.oraclecloud.com

  10. In the Allowed Scopes section, copy the Scope value for 1PaaS Permission.

    urn:opc:resource:consumer::all

Get an OAuth Access Token

With the information that you gathered, use the Oracle Identity Cloud Service REST endpoint /oauth2/v1/token to obtain a token. 

curl -k -X POST -u "client-id:client-secret" -d "grant_type=password&username=yourusername&password=yourpassword&scope=https://primary-audience-and-scope" "https://identity-cloud-service-instance-url/oauth2/v1/token"

Where:

  • client-id is the PSMApp client ID

  • client-secret is the PSMApp client secret

  • yourusername is the cloud platform service user name with an administrator role

  • yourpassword is the password for the user name

  • primary-audience-and-scope is a concatenation of the PSMApp primary audience URL and the 1PaaS permission scope

  • identity-cloud-service-instance-url is the REST server portion of the Oracle Identity Cloud Service Instance URL

For example:

curl -k -X POST -u "PSMApp-cacct-9z8x7c6v5b4n3m_APPID:c53b437-1768-4cb6-911e-1e6eg2g3543" -d "grant_type=password&username=yourusername&password=yourpassword&scope=https://psm-cacct-9z8x7c6v5b4n3m.console.oraclecloud.comurn:opc:resource:consumer::all" "https://idcs-9a888b7e6ebb44b4b65.identity.oraclecloud.com/oauth2/v1/token"

The following shows an example of the response returned.

{
   "access_token":"eyJ7NXQ...fMf46Q0yKopDxQ",
   "token_type":"Bearer",
   "expires_in":86400
}

Note:

The token string is truncated in the example response. You should copy the entire token string (within the quotation marks) as shown in your response.

Use the OAuth Access Token in Cloud Platform Service REST API Requests

After you obtain an OAuth 2.0 access token, you provide the token in a bearer token header of the cloud platform service REST request.

curl -i -X GET -H "Authorization: Bearer token-string" "https://primary-audience/rest-endpoint-path"

Where:

  • token-string is the OAuth access token that you obtained

  • primary-audience is the PSMApp primary audience URL

  • rest-endpoint-path is the relative path that defines the cloud platform service REST resource. Note that the identity domain ID of Oracle Identity Cloud Service might be used in the path.

For example, the following cURL command retrieves all Oracle Java Cloud Service instances. 
curl -i -X GET -H "Authorization: Bearer eyJ7NXQ...fMf46Q0yKopDxQ" "https://psm-cacct-9z8x7c6v5b4n3m.console.oraclecloud.com/paas/api/v1.1/instancemgmt/idcs-9a888b7e6ebb44b4b65/services/jaas/instances"
