How do I get a fiskaly certificate allocated when creating the Signer?

To have a fiskaly certificate automatically allocated to a Signer, follow these steps:

• Create the managed organization and taxpayer for your customer.

• Generate a UUID on your side for the Signer (this will be the signer_id).

• Call the createSigner endpoint with:

The UUID in the URL of the request.

• An empty JSON object {} as the request body (do not provide any external certificate).

Example:

PUT /api/v1//signers/d6625823-41a0-449a-b2e2-9e3ef5cf1c18 HTTP/1.1
Host: test.es.sign.fiskaly.com
Content-Type: application/json
Accept: application/json
Authorization: ••••••
Content-Length: 2

{}

In this case, SIGN ES will automatically allocate:

• a device certificate for TicketBAI territories, or

• a fiskaly-managed electronic certificate for Verifactu,

depending on the taxpayer’s territory.

You can then retrieve the Signer to see the certificate details (e.g. serial number), especially if you need it for TicketBAI certificate registration.
