Partner API

Build on CRISP

Managed Polymarket trading for your application, through your backend.

CRISP provides the trading layer; you own your product and its users' experience. Your backend provisions managed trading accounts, submits orders, retrieves portfolio and confirmed fills, and presents funding and referral rewards. Users do not need a CRISP login or leave your app for CRISP authentication.

For approved, assisted partner integrations. This documentation reflects the implemented Polymarket API reviewed on 13 September 2026. Capability flags and credential scopes determine availability. Ask CRISP for your approved endpoint, test environment and limits; do not assume a public sandbox or unrestricted access.

How it fits

Your frontend → Your authenticated backend → CRISP Partner API → Managed execution

HMAC credentials stay on your server. The credential determines the partner; there is no partner slug to put into every account or order request. Your stable externalUserId selects a user within that partner. Your backend must check the signed-in user's authority before choosing that ID. A partner key itself does not authenticate the end user.

Included capabilities

  • Headless managed accounts and optional contact/display identity.
  • Markets, books, requirements, order placement/cancel, positions and redemption.

The integration API does not provide KYC, a hosted end-user CRISP login, automatic linking to an existing CRISP account, exported signing keys, or non-Polymarket execution. CRISP's internal/admin APIs are not part of this contract.
