PDF invoice API

GET https://invoicetxt.com/v1/invoices/{id}/pdf with the same Bearer key that owns the invoice. The response is application/pdf, not JSON. Save the bytes as a file.

The customer can also open /download/{id}.pdf from the invoice link. Use the API download when your own system needs to store the file, attach it to a job record, or hand it to an accountant.

What is on the PDF

The PDF shows the invoice number, the client, the issue date, the due terms, each line, the tax and the total. Currency other than USD is stored on the invoice and shown in the on-screen invoice. The PDF amounts use the same numbers you sent.

If the invoice has been acknowledged, the on-screen invoice shows the signer’s name and time. Download the PDF after that event if you want the file that matches the latest total.

Errors

404 means the id is unknown or it belongs to another account. 401 means the key is missing or revoked. Do not retry a 401 in a loop. Create a new key in the workspace and replace the old one.
