Beware of Impersonation Scams

Government officials will NEVER do these things over a phone call:

1. Ask you to transfer money;
2. Ask you to disclose bank log-in details;
3. Ask you to install mobile apps from unofficial app stores;
4. Transfer your call to Police.

Call the 24/7 ScamShield Helpline at 1799 if you are unsure whether something is a scam.

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!
