# Step 6: Fill in your Twilio credentials in Postman!

Congratulations for successfully setting up your Twilio credentials! Now, input these credentials into your Postman account. This is a one-time set-up.

### How do I set up?

First, log into your [Postman](broken://spaces/qQYf99nZtDsAL7kqovkU) account using your official government email address.

*(If you prefer to watch a video on how to set up, scroll to the bottom of this page)*

Click on `Settings` on your Postman dashboard, and select `Add credentials +`
