Powerful Template Editor

Create an API with nested objects and arrays. Field types include text, number, boolean, date, country, email, URL, and image. Fields can be displayed as text, check marks, shapes, images, and QR codes.

(Demo is available for desktop browsers.)

Schema Validation

We automatically generate a JSON Schema for your API, including validations. Configure required and optional fields, or set minimum and maximum values for numbers. We return an error if you submit invalid data.

Example Schema

Automatic Online Forms

Every template has an automatically generated online form. Quickly test your templates by clicking a button to fill the form with random data. All plans includes unlimited free test PDFs.

date / time, country, email, URL, check, shape, image, and QR code.

Fillable pdfs

Fillable PDF Forms

FormAPI supports both fillable and scanned PDFs. When you upload a PDF with a fillable form, we will automatically import all of the existing fields.


Formats and Conditions

Split a date into month, day, and year. Display a check or a shape whenever a value matches a condition. Combine multiple values into a single string. Turn complex forms into simple APIs.



We 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.
