Then, set up a script or use a cron job to send your JSON data to the API endpoint whenever you need a report generated. The API will return the PDF, which you can save to your server or cloud storage. For more advanced automation, you can use webhooks to trigger actions after generation, like sending the PDF via email or uploading it to a CRM. This approach saves you hours of manual work and ensures consistency across all your reports.
