30106: Domain has not been set up for this account

This error means you tried to use Link Shortening click tracking before the domain was set up for the account. Complete the Link Shortening onboarding steps, including adding and verifying the domain in a Twilio Organization, before you use it with Messaging Services.

• You have not completed Link Shortening onboarding for the account, so the domain is not set up yet.
• You have not added and verified the domain in the Twilio Organization that owns the Link Shortening domain.
• The Twilio account you are using has not been added to the Organization, or the Messaging Service is not associated with the Link Shortening domain.

• Complete Link Shortening onboarding: use a domain or subdomain you own, create or use a Twilio Organization, add and verify the domain, add the Twilio account to the Organization, and make sure the account has a Messaging Service with at least one sender.
• Associate the Messaging Service with your Link Shortening domain from Messaging > Messaging Services, or use the Link Shortening domain's Messaging Services subresource in the API.
• If you are still setting up the domain, update the DNS records for the domain and allow time for propagation before retrying.
