Form data extraction API
Extract structured form data from free-text submissions
Sift Forms gives developers an API for turning messy user submissions into structured JSON. Send text plus a schema, receive extracted fields, confidence scores, warnings, and follow-up requirements.
REST

Webhooks

A practical API for unstructured form answers
Instead of forcing a custom parser into every intake workflow, define a schema once and let Sift Forms extract names, emails, amounts, categories, urgency, and custom fields from the raw submission.
Built for product teams
Use the API behind your own UI, combine it with the hosted widget, or route completed submissions into internal tools through webhooks.
Safer automation with confidence signals
Every extraction includes confidence and warnings, making it easier to decide whether to auto-route, ask for missing details, or send a record for review.
How it works
Create a schema
Define the fields and required values your workflow needs in the Sift Forms dashboard.
POST the text
Call the extraction endpoint with the raw message and schema ID from your application.
Use the JSON
Store the submission, trigger webhooks, create tickets, update records, or ask for missing required fields.
