Build on Capvant

Pull your deal flow, push referrals, and get notified the moment a status changes, all through one JSON API that mirrors what your team already sees in the Hub.

Three ways in

Pick your build path

Every integration into Capvant fits one of three shapes. Most teams end up using two.

Lender API, pull or push

List and retrieve the deals routed to your lane, report statuses, submit offers, and message clients: self-serve, with your own API key. Want deals pushed to your endpoint instead? Contact partnerships@capvant.com.

Lender API docs

Partner API, push referrals

Push-only by nature: submit funding referrals from your own CRM or platform and track each one through to commission, with an idempotency key so retries never duplicate a submission.

Partner API docs

Webhooks & embedded widgets

Register an HTTPS endpoint and receive signed events the moment a deal or referral changes, instead of polling. Partner widget embeds are provisioned from your dashboard.

Quickstart

Four steps to your first call

The whole loop, start to finish, in about five minutes.

01

Create a key

Lenders: capvant.com/lender under Team → API keys. Partners: capvant.com/partner under Settings → API keys. Shown once, store it server-side.

02

Ping the API

Send it in X-API-Key against GET /v1/ping and confirm your organisation name comes back.

03

List a page

GET /v1/deals or GET /partner/v1/referrals to see real records in your own shape.

04

Register a webhook

POST /v1/webhooks once you're ready to stop polling and get pushed events instead.

Status

Is the API up?

Live status for the API, docs, help center and marketplace is at status.capvant.com. For a per-key check, GET /v1/ping (and /partner/v1/ping) with your key confirms the API and your credentials are both good.
