Build with Soledgic's platform payment infrastructure API for marketplaces, creator platforms, and closed-loop app economies.

What are you trying to do?

Start with a product job. The endpoint reference explains the exact call after that.

Full API reference →

Create platform accounts

Add creators, buyer wallets, creator wallets, and the IDs your app will use later.

Take a purchase

Create checkout sessions for products, sessions, memberships, or in-app purchases.

Show wallet activity

Read balances, receipts, and transaction history for buyers, creators, and support teams.

Handle refunds

Route refund requests through Soledgic and keep platform fees, creator earnings, and holds aligned.

Pay creators

Check payout eligibility before any payout request, then track payout status.

Receive updates

Configure webhooks so your app is notified when important money events change.

Create your first creator accountPOST

curl -X POST https://api.soledgic.com/v1/participants \
  -H "x-api-key: slk_test_your_api_key" \
  -H "Content-Type: application/json" \
  -d '{
    "participant_id": "creator_456",
    "display_name": "Jane Creator",
    "email": "jane@example.com",
    "default_split_percent": 80
  }'

Universal integration flow

platform
  -> user wallet
  -> creator wallet
  -> product / session / order
  -> purchase
  -> platform fee + creator earnings
  -> refund / hold / reversal
  -> payout eligibility
  -> receipt / activity feed

Your app owns the user experience and product catalog. Soledgic owns the wallet, ledger, fees, earnings, refunds, holds, payout readiness, receipts, and audit trail.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

API Examples

Copy-paste curl commands for every endpoint — test without an SDK

Error Reference

HTTP status codes, error codes, rate limiting, and idempotency behavior

Webhooks

Receive checkout, payout, and refund events from the platform

Bridge Operations

Run sandbox bridge smokes, trace deliveries, and clean test data

SDKs & Libraries

Use the TypeScript SDK or integrate directly over REST

Why Soledgic?

Resource-First Treasury API

Creator accounts, wallets, holds, checkouts, payouts, refunds, webhooks, receipts, and activity 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, wallet transfers, and payout schedules without bolting treasury logic onto a checkout API.

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