Set Up PAC Web Services

Before you can send invoices and credit memos electronically, you must specify one or more providers of the electronic stamp that must be included in invoices in Mexico.

When you send an electronic document, it must receive a digital stamp by an authorized service provider, PAC, before it can be sent to your customer. The communication between Business Central and the PAC is managed through web services, and therefore, you must specify technical information about the web services of the PAC that you intend to use.

To use web services, you must identify the name of the method on the web service that processes requests for digital stamps. Your PAC can give you this information.

If your PAC offers the service of canceling signed documents, you must specify two web methods: one web method for requesting the digital stamp, and the other for canceling an already signed document.

1. Choose the icon, enter PAC Web Services, and then choose the related link.
