# Verify custom domain

> <Info>This API is in beta. Endpoints, fields, and behavior may still change, so avoid depending on it in production.</Info>

Asks the hosting provider to check the domain's DNS.

Verification normally starts on its own when you link a domain. Call this when you have just fixed the DNS records and don't want to wait for the next automatic check.

A successful call means the check was accepted, not that the domain is verified. Poll [Get custom domain status](/api-reference/get-custom-domain-status) for the result.

A domain whose DNS doesn't point to Base44 yet fails in a way this endpoint doesn't document. Treat any failure here as "the check didn't start", fix the DNS records, and call this again.
