This page is your map. It lays out the partner integration end to end so you can see how the pieces fit before you start building, then points you to the right guide for each step.

​
The journey at a glance

Funding is in beta. Your funding entity pre-positions pooled funds at Polymarket US and funds each participant’s trading account with instant deposit transfers that mirror their wallet allocation, via Partner Funding, enabled per partner. There is no per-participant bank-deposit step in the journey.

​
What you’ll build

A complete partner integration has a handful of components. You can build them incrementally in the order below.
Polymarket US is a streaming-first platform. REST endpoints are intended for one-off queries and are rate-limited; continuous data should come from streams. Keep this in mind as you design every component above.
1

Understand the platform and your role

Start with Your Role and the Platform Model. Keep the Glossary open in a tab.
2

Understand funding

Your funding entity pre-positions pooled funds and funds participant accounts with instant deposit transfers, with vendor fees declared per order and collected periodically — read the Partner Funding (Beta) model before designing your deposit, order, and fee flows. Contact your Polymarket US integration lead to enable funding for your integration.
3

Get connected

Complete partner onboarding, then set up authentication. Confirm you can call GET /v1/whoami successfully.
4

Onboard your participants

Implement the KYC flow. You collect each participant’s required information and submit it; Polymarket US performs the verification and decision. On approval, the Retail Participant and their account are provisioned automatically. See Onboard Participants.
5

Place your first order

Walk through the Quickstart to authenticate, list instruments, and place and cancel an order end to end.
6

Monitor and reconcile

Subscribe to the order, position, and balance streams and maintain a local mirror. Add a webhook receiver for KYC and account lifecycle events.
