Due to great variations of input sources, this tutorial will assume you have already set up the trigger phase before the “Do this” part, where PDF.co comes into play.

IRS Form F1040

3. Set Up Values to Enter in Fillable Fields

First of all, we need to find which exact field names are used inside this PDF form. To get field names we should

  1. upload the PDF file form into PDF Information and Fields online tool on PDF.co
  2. it will display the following list and you will see all fields under FieldsInfo section:

fieldName indicates a name of control we can fill out. It can be a text edit box, checkbox, or another control. For the text edit box field, we just need to set its text. For checkbox controls, we can use true or false to enable or disable a check inside this checkbox.

Do not see any form field names inside your PDF form? This tutorial applies only to PDF forms with fillable input fields. But you can always just add text, images, and links to any PDF using PDF.co and its PDFFiller by following this tutorial: https://pdf.co/add-text-and-images-with-links-to-a-pdf-using-zapier

3. Use the Strings Provided Below to Fill Fields

Important: pages indexes start at 0 (zero). So, page 0 (zero) is the very first page, page 1 (one) is the second page, and so on.

In Zapier we should add the following strings which are telling PDF.co to fill the field by its name on a given page on a page with a given value.

The format is pageIndex;fieldName;value.

  • For example, to fill the edit field on the 2nd page (page index is 1 ) with John A. Doe:
    1;topmostSubform[0].Page1[0].f1_02[0];John A. Doe
  • And to select and check the checkbox named Married / Filling jointly on the 2nd page (page index 1):
    1;topmostSubform[0].Page1[0].FilingStatus[0].c1_01[1];true
  • And also to put the value 123456789 into the SSN form field on the same 2nd page (page index 1):
    1;topmostSubform[0].Page1[0].YourSocial_ReadOrderControl[0].f1_04[0];123456789
