# 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 re-check the domain's DNS now.

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

<Note>A 200 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.</Note>

A domain whose DNS does not resolve to Base44 yet does not come back as a documented error code. Treat any non-200 here as "the check did not start", fix the DNS records, and call this again.

<Note>This endpoint accepts a personal API key. Workspace API keys are not authorized for it and are rejected with a 403.</Note>
