Resource Flow

participant
  -> checkout_session
  -> wallet balance / hold
  -> payout
  -> refund

reconciliations
  -> fraud evaluation
  -> compliance monitoring
  -> tax documents / summaries

The public API is resource-first. Edge functions validate and route requests into shared treasury services, and those services commit balanced ledger writes through PostgreSQL RPCs.See the architecture details

Shared identity, participant linking, ecosystems, and fixture cleanup are operator control-plane features. They require authenticated dashboard sessions and are intentionally excluded from the public `/v1` API reference and the TypeScript SDK.

Quickstart

Create a participant, launch checkout, inspect balances, and send payouts

Authentication

Authenticate resource requests with API keys and environment isolation

Core Concepts

Understand the resource layer, ledger guarantees, holds, and replay safety

API Reference

Generated reference for treasury resources and supporting accounting APIs

Webhooks

Receive checkout, payout, and refund events from the platform

SDKs & Libraries

Use the TypeScript SDK or integrate directly over REST

Why Soledgic?

Resource-First Treasury API

Participants, wallets, holds, checkouts, payouts, refunds, reconciliations, fraud evaluation, compliance monitoring, and tax resources are the canonical public surface for new integrations.

Ledger Guarantees

Money movement maps to balanced entries and atomic database writes. The ledger either commits the full state change or nothing.

Built for Platform Economies

Model delayed release policies, creator balances, internal transfers, and payout schedules without bolting treasury logic onto a checkout API.

Need help?

Start with the quickstart, then move into the API reference once your participant and checkout model is clear.
