# Capture a Lead

> Records a donor who submitted a page without making a payment, such as a newsletter or interest signup.

Send the `donor` details, the `emailLists` to subscribe them to, and any `customFields` or `customCollections` the page collected.

<Note>Send `isTestMode=true` to try the call without recording a live donor.</Note>

<Note>The spec does not document error responses for this endpoint beyond `401`, so the causes aren't listed with the responses here. Errors still arrive in the [ProblemDetails envelope](/raise/error-handling#the-problemdetails-envelope) the rest of the Raise API uses — handle a rejected request (`400`), and a path ID that doesn't resolve (`404`), as you would on any other endpoint.</Note>
