PDF Form Fields API

Start building for free today – no credit card required.

List every form field of a PDF with a single API call: its name, type, current value and the options it accepts, together with what the field means – the description stored in the PDF and the text printed around it on the page. Prefill forms from your data, read what a customer entered, or let an AI agent understand a form before it fills it.

Also available as an MCP tool

Claude, ChatGPT, Cursor or your own agent can call read-pdf-form directly.

Benefits of our PDF Form Fields API

Field names in real-world forms are often cryptic, like Text12 or f1_05[0]. Next to every text field, checkbox, radio button, dropdown and list box, the API returns its position on the page and the labels printed left, right, above and below it, as well as the row and column it belongs to in a table. So you and your agents know what each field asks for, and the field names returned are exactly what our PDF Form Filling API takes.

Read our API documentation to learn how to read PDF form fields.

Multi-language Code Example

curl -X POST https://apdf.io/api/pdf/form/read \
  -H "Authorization: Bearer TOKEN" \
  -d file="FILE_URL"

No-Code PDF Form Reading

Integrate our PDF Form Fields API with Zapier Webhooks to automate your form processing. Read the answers of filled PDF forms that arrive by email or upload and pass them on to your CRM, spreadsheet or database – from hundreds of apps supported by Zapier, without typing anything over by hand.

After the API call

Your code made the PDF.
Then it went dark.

Opened, read, re-read, dropped on page 4 — you never see any of it. Share the PDFs you generate through Apdf recipient links, and every signal becomes something you can act on: ping Slack, update the CRM, let an agent follow up. Same account, same API token, one more call.
