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

Why is this step needed? You can think of credentials as a passcode that you need to enter into a keypad in order to get into a door. We need your credentials to contact Twilio's API.

{% hint style="info" %}
If you want to be able to reuse your credentials, you need to save them under settings.

Otherwise, the credentials will not be saved, and you will need to key them in each time you send a campaign. We recommend you do the one-step set-up in `settings` to save you the time in the future.
{% endhint %}

#### How do I set up?

First, log into your [Postman](https://postman-v1.guides.gov.sg/~/changes/YeLkNyuQOW0qmXU37t7T/campaign-guide-sms/onboarding-overview/broken-reference) 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.

Add in your Twilio credentials - you should have saved the 4 components needed, as advised to you in [step 4](https://postman-v1.guides.gov.sg/~/changes/YeLkNyuQOW0qmXU37t7T/campaign-guide-sms/onboarding-overview/step-4-configure-your-twilio-account).

Note that the *credential label* is just a friendly name for your to keep a record of these credentials.

Find your account SID [here](https://guide.postman.gov.sg/campaign-guide-sms/onboarding-overview/step-4-configure-your-twilio-account#1.-your-account-sid).

Find your API key SID [here](https://guide.postman.gov.sg/campaign-guide-sms/onboarding-overview/step-4-configure-your-twilio-account#2.-your-api-key-sid).

Find your API Secret key where you [stored](https://guide.postman.gov.sg/campaign-guide-sms/onboarding-overview/step-4-configure-your-twilio-account#3.-your-secret-key) it. Do note that this is no longer available on your Twilio console once you have completed the Twilio account set-up. As reminded earlier, you should have saved the secret key somewhere safe, where you can access for this set up in Postman.

Find your messaging service ID [here](https://guide.postman.gov.sg/campaign-guide-sms/onboarding-overview/step-4-configure-your-twilio-account#4.-your-messaging-service-sid-without-buying-a-phone-number).

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

![Key in your mobile number](https://4126954886-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-MAQH3DF49Lq0AJudrbF%2Fuploads%2Fgit-blob-b07b814700c422124dd4215f572676c1282b10fb%2Faccounts-test-cred.jpg?alt=media)

Receive a success message once your credentials have been validated.

![Success message if your credentials are correctly set up](https://4126954886-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-MAQH3DF49Lq0AJudrbF%2Fuploads%2Fgit-blob-4200526448d13a67fe0ad61a988423798e5494a6%2Faccounts-cred-valid.jpg?alt=media)

An SMS will also be sent to your mobile number.

![Test SMS - check that your Sender ID is correctly reflected.](https://4126954886-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-MAQH3DF49Lq0AJudrbF%2Fuploads%2Fgit-blob-9820b7796b5ba8037a5670761589544a0cb4d9f9%2Fphone-cred-valid.jpg?alt=media)

#### 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.
