Overview

Fill PDF form fields from JSON values — and optionally flatten the result so it can't be edited. Auto-generate filled contracts, applications, tax forms and government paperwork at scale, straight from your data.

PDF Form Filler input — configure the options in the Apify Console

What it does

Fills text fields, checkboxes, radio buttons and dropdowns from a { field: value } map.
Optionally flattens the form so the values become permanent.
Lists the form's available fields so you know exactly what to fill.

Use cases

Document automation — generate filled contracts/applications from a database or CRM.
Government & tax forms — batch-fill standard PDF forms.
HR & onboarding — pre-fill offer letters and forms per employee.

Input

{ "pdfUrl": "https://example.com/form.pdf", "fields": { "Name": "Ada Lovelace", "Email": "[email protected]", "Subscribe": true }, "flatten": false }

Field	Type	Description
`pdfUrl`	string	A fillable PDF (with AcroForm fields).
`fields`	object	`{ fieldName: value }` — strings, booleans (checkboxes), option values (dropdowns/radios).
`flatten`	boolean	Lock the filled values so they can't be edited.
`outputName`	string	Output filename.

Tip: run once with any values to see availableFields in the output, then map your data to those names.

Can I automate it? Yes — via integrations on the Apify platform and the Apify API.

Notes

Original clean-room implementation.

Input

Field	Type	Description
`pdfUrl` required PDF form URL	string	Direct link to a fillable PDF (with AcroForm fields).
`fields` required Field values	object	A { "fieldName": value } map. Text fields take strings, checkboxes take true/false, dropdowns/radios take the option value. Run once with any values to see availableFields in the output.

`outputName` Output filename	string	Name for the filled PDF file. Default: `"filled.pdf"`
