How it runs

The automated pipeline, trigger to output.

  • TriggerPartner POSTs CSV to webhookHTTP webhook
  • LogicParse and validate rows against schema contract
  • LogicBranch accepted rows from rejected rows
  • ActionInsert accepted rows into PostgresPostgreSQLPostgres
  • ActionArchive rejected rows + defect report to S3AWS S3
  • OutputReturn JSON verdict in webhook responseHTTP webhook

What it does

This workflow exposes a webhook that partners POST their CSV to. It validates the payload against your contract schema on the spot and returns a structured verdict in the HTTP response: how many rows were accepted, how many were rejected, and the exact reason for each rejection. Clean rows are committed to Postgres and the quarantined rows are archived to S3 for audit.

When to use it

Use it when partners integrate programmatically and need immediate feedback rather than an out-of-band email hours later. The synchronous response lets their system retry or correct the feed in the same call.

How it works

  1. 1A partner POSTs a CSV to the webhook endpoint, firing the trigger.
  2. 2Rows are parsed and validated against the schema contract.
  3. 3The flow branches accepted rows from rejected rows.
  4. 4Accepted rows are inserted into the Postgres staging table.
  5. 5Rejected rows and a defect report are archived to an S3 quarantine prefix.
  6. 6The webhook responds with a JSON verdict listing counts and per-row failure reasons.
