How to generate an e-invoice using an API?

Prepare the Invoice Data: Your ERP or billing system generates an invoice in your internal format.

API Call: Your system sends this invoice data to the e-invoicing API (like Complyance's) in a structured JSON format.

Validation & Translation: The API provider(complyance) validates the data against business rules and translates it into the exact format required by the UAE FTA (PINT-AE schema).

Submission to IRP: The validated invoice is digitally signed and submitted to the government's Invoice Registration Portal (IRP).

Receive IRN: The IRP processes the invoice, generates a unique IRN and QR code, and sends this back to your system via the API.

Update Your System: Your ERP system automatically receives the IRN and updates the invoice record, often then proceeding to print the compliant invoice or email it to the customer.
