Template Editor Demo

(Demo is available for desktop browsers.)

Schema Validation

We automatically generate a JSON Schema for your API, and validate your API requests against this schema. This means that PDFs will always be rendered with valid data.

Example Schema

Online Forms

We automatically generate an online form for your templates. Quickly test a template by filling out the form with random data. All plans includes unlimited free test PDFs.

HTML Editor Demo


FormAPI can send webhooks or post a message to Slack when a PDF is generated. More integrations are coming soon, such as Dropbox, Google Drive, Zapier, and IFTTT.

Template Logic

Display a check mark when a value matches a condition. Split a single date value into month, day, year. Combine multiple values into a single string. Turn a complex form into a simple API.

Bitcoin Blockchain Verification

FormAPI can verify the integrity and existence of your PDF by embedding the file hash in a Bitcoin transaction. This proves that your PDF existed at a certain point in time.
