PEC Communication to the Chamber of Commerce

PEC Communication to the Chamber of Commerce is Openapi's exclusive service that automates the process of communicating the Certified Email (PEC) address to the Chamber of Commerce.

The service supports any type of PEC mailbox, even those not activated through Openapi, ensuring maximum flexibility.

To proceed with the PEC communication, the following API requests must be made.

PEC Communication Request

The first useful endpoint for PEC communication is

POST  /comunica_pec. This endpoint initializes the request.

REQUEST EXAMPLE

POST /comunica_pec/

This is an example request to communicate the PEC address [email protected]

https://pec.openapi.it/comunica_pec

The following values must be included in the request body:

This is an example Payload:

{
    "casella_pec": "[email protected]",
    "cf": "RSSXXXXXXXX56E",
    "nome": "mario",
    "cognome": "rossi",

    "cf_piva": "12345678910",
