Simplified OAuth Config for Oracle Integration Cloud REST API using Postman !!!

This blog will be discussing very specific use case requirement which is more developer oriented and providing a quicker and efficient solution to invoke Oracle Integration REST API using OAuth access_token for testing purpose.

As an integration developer time to time you need to invoke Oracle Integration REST API to test API functionality. All the REST API in OIC needs a header parameter called “Authorization” which must needs to hold a valid access_token value in this format “Bearer access_token“.

In above format, “Bearer” is static world, However, access_token is the token value which we get after successfully OAuth Authentication from Oracle Identity Cloud Service.  Getting access_token from IDCS using code credentials flow is multi steps and cumbersome process.

However, developer can leverage Postman environment and variable features to simplify the process of getting access_token. That’s what, I will be covering in this blog.

Before I proceed further, I must redirect you to read my colleague blog which has greater in-depth explanation about what is IDCS, how IDCS govern security aspect of all Oracle PaaS products such as Oracle Integration Cloud, Analytics Cloud, Digital Assistant and so on and OAuth client and token generation process etc. I am recommending you to read his blog because I will be using few artefacts e.g. IDCS URL, Client ID, Client Secret etc which we need to get from IDCS OAuth Client Application as per the process given in his blog.
