Check out our CorpPass and Callback URL Guide!

Do you know that many of our APIs are used with CorpPass? IRAS CorpPass API leverages on OAuth 2.0 which can be a challenge to integrate and test with your software. Therefore, we have prepared a guide to help you get started. We have also included a video walkthrough to help you test the CorpPass API with Postman. Look out for it in the guide!
