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

### How do I set up?

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

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

Add in your Twilio credentials.

For more information on how to map your Twilio credentials to Postman, refer to [4. Configure your Twilio account](/campaign-guide-sms/onboarding-overview/step-4-configure-your-twilio-account.md) when filling up the following details

1. [Account SID](https://postman-v1.guides.gov.sg/campaign-guide-sms/onboarding-overview/pages/J89FopQzDZgJb9qSC8yv#id-1a.-account-sid-postman-v1-campaign-settings)
2. [API Key SID](https://postman-v1.guides.gov.sg/campaign-guide-sms/onboarding-overview/pages/J89FopQzDZgJb9qSC8yv#id-2a.-api-key-sid-postman-v1-campaign-settings)
3. [API Secret](https://postman-v1.guides.gov.sg/campaign-guide-sms/onboarding-overview/pages/J89FopQzDZgJb9qSC8yv#id-3a.-api-secret-postman-v1-campaign-settings)

Then, key in your phone number to validate your credentials.

Receive a success message once your credentials have been validated.

#### Congratulations! At this step, you have completed the set-up.

You can now start sending campaigns with your own credentials. You will be billed by Twilio for the SMSes that you send.
