SOAPUI - SoapUI to OIC Service Call using OAuth 2.0

Overview

This setup allows SoapUI to invoke an Oracle Integration Cloud (OIC) REST integration securely using OAuth 2.0 ( example, Client Credentials) authentication.

Supported Version

OAuth 2.0 support is available in SoapUI Open Source 5.x and later versions. SoapUI provides built-in OAuth 2.0 authorization profiles and supports standard grant types such as:

Authorization Code

Client Credentials

Password Credentials

Implicit Grant

Setup Steps

Configure OIC Integration Security:

Open OIC: Integrations → Open Integration → Trigger → Security

Select: OAuth 2.0

Configure:

Activate the integration.

Generate Access Token in SoapUI

1. Open SoapUI: Request → Auth → Add Authorization → OAuth 2.0
2. Enter: Value
1. Grant Type
2. Client Credentials
3. Access Token URL
4. OAuth Token URL
5. Client ID
6. Client Secret
3. Click: Get Access Token

Note: In the Scope, there should not be any double quotes.

Conclusion

Using SoapUI (5.x and later) with OAuth 2.0 support makes it easy to securely test and invoke OIC REST/SOA services without custom token handling. By configuring the OAuth 2.0 authorization profile, generating the access token, and attaching it to the request, service testing becomes faster, reusable, and aligned with modern authentication standards. For better compatibility and stability, using SoapUI 5.7.0 or later is recommended.
