Send a fax
Send a fax to a US or Canada fax number with Faxwell (as low as 6¢ a page, no subscription, no account needed first). Give the document as base64 (PDF, PNG or JPEG), as a public https link to one, or as the plain text of a letter you wrote. This prepares the fax and returns a link for the user: they check it and pay (Apple Pay, Google Pay or card) or use page credits they already have, and it sends automatically. Nothing is sent or charged before that. If you can’t pass the file, call this with just the number: the user can add the document at the link.
