Massive REM

The Massive REM API is available in the standard version, allowing the sending of up to 3,500 messages per day at a cost of €0.05 per individual message. The service requires the activation of a PEC mailbox with the domain @pecmassiva.com.

Additionally, two annual subscription options are available:

1. 365,000 messages per year at just €0.004 per message
2. 1,200,000 messages per year at just €0.002 per message

Please note that the subscription activation does not include the activation of the @pecmassiva.com mailbox, which must be completed separately.

To check the availability of the desired Certified Email address, a request must be made to the GET /pec.openapi.it/verifica_pec/{pec} endpoint.

The request must specify the Certified Email address whose availability is to be checked.

The response indicates whether the address is available (if positive, the message is 'true', if negative, it is 'false').

Once you have ascertained the availability of the REM address, you can proceed with its registration via the POST endpoint https://pec.openapi.it/pec.

The data to be passed in the body of the request are:

• certified email box
• box type
• customer type and sub-type
• information on the applicant (name and surname, email and telephone, tax code, date of birth, gender, country and province of birth)
• name and tax/VAT code of the holder of the email
• holder's full address (street, municipality, postal code, country, province)
• any callback url set

You may also activate auto-renewal by adding the optional 'auto-renewal' parameter with the value 'true' to the body (currently the default is 'false').

The response will contain a series of information including a summary of the characteristics of the REM. The activation status of the REM and the id are also specified.

The id will be crucial for the next activation steps, for checking the status and for renewal.

You can complete the PEC activation via the PATCH /pec/{id}/attivazione endpoint.

To complete this operation you must download the required form (GET /pec/{id}/modulo_attivazione) and proceed to send the form, correctly filled in and signed together with the applicant's ID. It must be a single document and in PDF format.

The id is the one obtained in the previous endpoint (POST /pec.openapi.it/pec).

Yes, you can check the status of your Certified Email Messages at any time via the GET /pec/{id} endpoint and from the REM's id value.

The response provides a lot of information. First the status of the Certified Email (e.g. registrata=registered) and then other information such as:

• owner of the CEM
• domain
• registration date
• available storage space
• any callback url set

PLEASE NOTE: Currently verification is only possible for customers who have activated via API and not via www.pecmassiva.com. This endpoint is not valid for verifying the status of the FLAT Massive CEM.
