The easybill integration is used by 500+ users. The synchronization of invoices is possible with HubSpot without any problems. What is missing is a receipt image, i.e. a link to the PDF or an attached file to the invoice data record. The integration is from HubSpot, not from a third-party provider. I would therefore like to see this integration extended to include the PDF document image.
Here is the information from Easybill:
It is definitely possible to download documents in PDF format.
You need the “Get /documents{id}/pdf” command from Easybill REST-API documentation.
You must first retrieve the IDs of the corresponding documents and then pass them with the previous command so that the PDF of the corresponding document is retrieved.
