SHAKEN/STIR Onboarding with the Trust Hub REST API (Direct Customers, no Subaccounts)

(information)

Info

For general information on the Trust Hub API, go to the Trust Hub API Docs.

This page walks Direct Customers with no subaccounts through creating a SHAKEN/STIR Trust Product with the Trust Hub REST API.

Not a Direct Customer with no subaccounts? Find the appropriate onboarding instructions below:

Direct Customers (No Subaccounts)

1. Create a Primary Business Profile in your Parent Account in the Console's Trust Hub and submit for vetting

In your Console, navigate to Trust Hub -> Customer Profiles to create your profile.
You will only need to do this one time.
For more information on Business Profiles and vetting, go to the Trust Hub Docs.

2. Add Phone Number(s) to your Primary Business Profile

This is required before you can add a phone number to your SHAKEN/STIR Trust Product.
You'll need your Business Profile's SID,
- To find your Business Profile SID in the Console, navigate to Trust Hub -> Customer Profiles -> View Profile Details.
- If you'd prefer to look up your Business Profile SID via API, see the Additional API Calls section.
- Business Profile SIDs begin with "BU".
You'll also need your Phone Number SID(s)
- To find your Phone Number SIDs in the Console, go to your Dashboard. In the Project Info section, click on See all phone numbers, then click on a phone number to find the SID.
- To find your Phone Number SIDs via API, see the Additional API Calls Section.
- Phone Number SIDs begin with "PN".
- In the API Call below, don't change the ChannelEndpointType. It needs to be phone-number to add a phone number to your Business Profile.
