REST API Layer
70+ modules accessible via clean, versioned REST APIs — JSON format, token auth, rate limiting, and interactive documentation included.
Every capability in the YoApp platform is accessible via a well-designed, versioned REST API. Whether you are building a custom mobile app, integrating with your core banking system, or automating an internal workflow, the API gives you programmatic access to every module — with the same security controls, audit logging, and rate limiting that govern the user interface. The interactive documentation makes integration fast and self-service for any developer.
Everything you need, nothing you don't
Versioned Endpoints
All endpoints are versioned (e.g. /api/v1/, /api/v2/) — allowing new functionality to be released without breaking existing integrations. Deprecated versions are supported for a published sunset period.
Bearer Token Authentication
API clients authenticate with bearer tokens scoped to specific modules and actions. Tokens have configurable expiry and can be rotated or revoked instantly from the admin panel.
JSON Request & Response
All requests and responses use clean, consistently structured JSON. Error responses include a machine-readable error code, a human-readable message, and a reference ID for support queries.
Per-Client Rate Limiting
Each API client has configurable rate limits — requests per second, per minute, and per day. Limits can be adjusted per client tier without a code change.
Interactive API Documentation
Built-in interactive API documentation (OpenAPI / Swagger) — browse every endpoint, see request and response schemas, and make test calls directly from the documentation UI.
Webhook Support
API clients can register webhook endpoints to receive real-time event notifications — eliminating the need for polling and reducing integration complexity.
Idempotency Keys
Clients can include an idempotency key on write requests — preventing duplicate operations if a request is retried after a network failure.
API Access Logs
Every API call is logged — client identity, endpoint, request payload hash, response code, and latency — accessible for debugging and security review.
Built for your team
Build integrations, mobile applications, and automation workflows using a well-documented, consistent API — with a sandbox environment for testing before going to production.
Design integration architecture that connects YoApp to your core banking system, ERP, or data warehouse — using documented, versioned REST endpoints that won't break without notice.
Integrate YoApp's financial services capabilities into your own product — payments, lending, vouchers, and notifications — via a single, comprehensive API layer.
