start_domain_verification

It requires a paid plan, the Manage domains permission, room on the site for another custom domain, up to 10, and a domain that does not already belong to this site or another one. A domain another site is only waiting to verify does not block it.

Pass a bare hostname. A value with http:// or https://, a path, or fewer than 4 or more than 253 characters is refused with the same messages as the Custom Domain field. A leading www. is dropped, so www.example.com verifies example.com.

A site has one pending verification at a time, so starting a new one replaces any earlier one. The answer carries the record to add as verificationTxtName, which is _modulify-verification. followed by the domain, and verificationTxtValue. Once it is in place, verify_domain is the step that actually adds the domain, and cancel_domain_verification abandons the attempt. See A domain waiting on verification.
