Developer-First Documentation

Comprehensive API docs, SDKs, sandbox environment, and dedicated developer support

Built for Developer Workflows

SimplifyLabs is designed around developer experience. Our API documentation is comprehensive, our SDK implementations are clean and well-typed, our sandbox environment mirrors production, and our webhook system is reliable. You integrate once and it works—no mysterious failures, no undocumented edge cases.

Bypass App Store Payment Restrictions

Apple and Google take 30% on in-app purchases and restrict the payment methods apps can offer. Crypto payments via SimplifyLabs can be processed outside the in-app purchase system for eligible content types. For apps where this applies, the fee savings are transformational.

Global User Base, No Payment Friction

Mobile app users are global—and card payment declines from international users represent real revenue loss. SimplifyLabs crypto payments work from any country, for any user, without the geographic inconsistency of card networks. Your global DAU can all convert to paying users.

In-App Purchase Without Platform Dependency

Building on top of Apple or Google's in-app purchase system creates platform dependency and policy risk. SimplifyLabs gives you a payment layer you control entirely. Changes to platform policies don't affect your crypto payment flows.

Real-Time, Programmable Payment Events

SimplifyLabs webhooks fire on every payment event—initiated, confirmed, failed, refunded. Your app responds in real time: unlock content, credit wallets, activate subscriptions, or trigger any business logic. No polling, no delays, no manual reconciliation.

P2P and Social Payment Flows

Building an app with user-to-user payments, tipping, or social commerce? SimplifyLabs supports P2P crypto transfers through our API. Build Venmo-style crypto flows, content creator tipping, or marketplace escrow with the same infrastructure.

iOS & Android SDKs

Native SDKs for iOS (Swift/Objective-C) and Android (Kotlin/Java) with full API coverage. Pre-built UI components for payment flows that match your app's design system, plus low-level API access for fully custom implementations.

RESTful API

Comprehensive API covering payments, wallets, payouts, webhooks, and reporting. Full OpenAPI documentation with interactive playground. Versioned API ensures your integration doesn't break on updates.

Webhook System

Reliable webhook delivery for all payment events with retry logic, delivery logs, and endpoint verification. Configure webhooks per event type for surgical control over which events trigger which business logic.

Sandbox Environment

Full production-equivalent sandbox for development and testing. Test payment flows, webhook delivery, and error handling without real funds. Testnet crypto available for end-to-end testing.

In-App Wallet Management

API for custodial in-app wallet management. Users hold crypto balances within your app without needing external wallets. Deposit, withdraw, and transfer APIs available.
