Fieldproof Collection Network — Developer Documentation

Fieldproof (a Fluxus Forge product) runs a field-collection network operated by Quikkred Financial Services: verified collection partners who visit your overdue borrowers, collect payment on your own payment rails, and feed every update back into your system as signed, sequenced events.

Integrating means two data flows:

1. Cases in — you POST your overdue loans to our API (push), or we fetch them from an endpoint you expose every 30 minutes (pull), or Fieldproof ops imports a CSV you send (CSV).
2. Our field partners run the entire visit / collection workflow — nothing for you to build there.
3. Money goes directly to you — either into your static UPI QR / bank account, or through payment links minted by your own gateway. Fieldproof never holds your borrowers' funds, and cash is never accepted on your cases.
4. Updates out — every meaningful change (case.received, payment.collected, case.closed by default; case.assigned and visit.completed on request) is delivered to your HTTPS webhook as a signed, per-case-sequenced event, with at-least-once delivery, a self-serve delivery log and replay, and a cursor-based poll API as fallback.

All money values everywhere in this API are whole INR rupees — never paise.

What integration takes

Path	You build
Push API (recommended)	One outbound HTTPS client that signs requests + one webhook receiver (or a poller)
Pull API	One cursor-paged GET endpoint on your side + one webhook receiver (or a poller)
CSV	Nothing to build — you send a file in our column format; updates still arrive by webhook or poll

Payments add at most one more piece: nothing if borrowers pay into your static QR / bank account (Fieldproof ops verifies the proof), or a small mint-link endpoint plus one confirm call if you want links from your own gateway.

Start with the integration paths chooser, register via onboarding, then follow the quickstart — it takes you from a signed health check to your first case.received webhook against the sandbox.
