Supabase PDF Automation

Connect Postgres records, Storage files, Edge Functions, and PrefillPDF into complete document workflows.

Supabase can store application records, extracted document fields, workflow status, and PDF files. PrefillPDF handles document generation and extraction.
Use a server route or Edge Function to read Postgres data, call PrefillPDF, then save the returned document or structured JSON back into Supabase.

Common Supabase workflows

Database record to generated PDF

Read a record, map fields into a template, and save the resulting PDF path or URL.

Storage upload to extraction

Process an uploaded PDF, extract JSON, and write normalized fields into Postgres.

Status-driven document workflow

Generate documents when a record reaches an approved, completed, or ready state.

How the integration works

1

Create the record or upload

Store structured data in Postgres or receive a PDF in Supabase Storage.

2

Call PrefillPDF securely

Use a server environment or Edge Function so API credentials remain private.

3

Save the result

Write extraction fields to Postgres or save the generated PDF to Storage.

4

Update workflow status

Track processing, completed, and failed states for reliable operations.

Can extraction results be stored in JSONB?

Yes. You can store the complete response in JSONB and also map important fields into dedicated columns.

Where should I keep the PrefillPDF API key?

Keep it in secure server environment variables or Supabase secrets, never in browser-exposed code.
