Automate PDF Form Filling
Upload a fillable PDF and DocuPotion maps every input field for you. Then generate populated versions of the form from your own data, one at a time or thousands at once, using one of our integrations or our REST API.

From fillable PDF to automated template
Upload the fillable PDF you already use and DocuPotion reads its input fields and assigns each one a sensible label. Review the mapping, then send your data and get back a finished, populated PDF.
Pass plain values, check or uncheck boxes with booleans, and let long entries wrap neatly across multiple lines. Every request returns a link to the filled PDF, ready to send.
Upload your fillable PDF
Create a new template and upload the fillable PDF you already use. DocuPotion analyses the document and detects every input field, checkbox, and text area inside it.
Review the field mapping
DocuPotion maps each field to a clear label automatically. Rename anything you like, or split grouped fields such as a multi-line address into separate inputs.
Generate filled PDFs
Send your data through one of our integrations or the REST API. DocuPotion returns a populated PDF for every record, so you can fill one form or thousands without touching them by hand.
More than a PDF form filler
Filling fillable PDFs is one of the ways DocuPotion automates your documents. Here are some other features to help with your document generation.

Frequently asked questions
What does it mean to automate PDF form filling?
Automating PDF form filling means populating a fillable PDF from your data instead of typing into each field by hand. You upload the form once, map its fields, and then generate completed copies on demand. With DocuPotion you send the values for each field and get back a finished PDF, so the same form can be filled for one person or for thousands of records without any manual work.
How do I automatically fill out a PDF form?
Upload your fillable PDF to DocuPotion and it detects and labels every input field for you. Check that the mapping looks right, then send your data through one of our integrations or the REST API. DocuPotion merges your values into the form and returns a populated PDF for each record, so the whole process runs without anyone filling the form manually.
Can I fill a PDF form using an API?
Yes. DocuPotion gives every template a REST endpoint. Make a POST request with your API key, the template ID, and a data object containing the value for each mapped field. The response includes a link to the filled PDF. You can fill text fields, set checkboxes with booleans, and pass long values that wrap across multiple lines, which makes it straightforward to generate completed forms from any application you build.
Do I need to be a developer to fill PDF forms automatically?
No. Native integrations with Airtable, Bubble.io, n8n, and Zapier let you fill forms directly from the tools you already use, triggered by a new row, a form submission, or any event in your workflow. The REST API is there too if you would rather build form filling into your own application.
What kinds of fields can DocuPotion fill?
DocuPotion handles the field types found in most fillable PDFs, including text inputs, checkboxes, and grouped fields such as a multi-line address. Checkboxes accept boolean values so you can tick or clear them per record, and long text wraps neatly onto multiple lines instead of overflowing. When several inputs belong to one label, you can keep them grouped or split them into separate fields, whichever suits your data.
