FillPDF Service is the official companion API service for the FillPDF Drupal module.
This is how it works:
- You install FillPDF on your Drupal site and choose FillPDF Service as your PDF-filling method.
- You upload and configure an editable PDF form (see documentation).
- You set up a link to trigger the form to be filled, and Drupal asks FillPDF Service to do the work when this happens.
- FillPDF Service sends the completed form back to Drupal, and Drupal does the rest. Usually, that consists of prompting the user to download the completed PDF or saving it to a configured file path.
