Developer Sandbox
A full-featured sandbox with test credentials, simulated integrations, and a pre-loaded demo dataset — build and test without touching production.
The Developer Sandbox is a complete, isolated copy of the production platform environment — pre-loaded with realistic demo data, connected to simulated mobile money and utility APIs, and provisioned with test API credentials. Developers can build integrations, test automation workflows, and validate their applications end-to-end before going live — with no risk of affecting real customers, real money, or real audit records.
Everything you need, nothing you don't
Full Platform Replica
The sandbox includes every module available in production — loan origination, payments, vouchers, GL, reporting — configured to mirror a typical production setup.
Simulated Mobile Money APIs
All mobile money integrations (EcoCash, OneMoney, InnBucks, bank APIs) are simulated in the sandbox — returning realistic success, failure, and timeout responses without triggering real transactions.
Test API Credentials
Each developer or integration project gets its own set of sandbox API credentials — scoped to specific modules and actions — separate from production credentials.
Pre-Loaded Demo Data
The sandbox is pre-populated with demo customers, loan records, transactions, and agent data — so developers can test against realistic data volumes without manual setup.
Interactive API Documentation
The sandbox includes the full OpenAPI documentation with live request execution — developers can make test API calls directly from the documentation browser.
Scenario Simulation
Trigger specific scenarios — payment failure, loan overdue, insufficient float — via configurable simulation controls, enabling thorough testing of error-handling and edge-case logic.
On-Demand Reset
Reset the sandbox to its default state at any time — clearing all test data and returning it to the pre-loaded demo dataset — with no impact on production.
Webhook Testing
Register webhook endpoints and trigger test events from the sandbox — verifying that your endpoint receives and processes YoApp event payloads correctly before production go-live.
Built for your team
Build and test integrations, mobile applications, and automation workflows against a realistic platform environment — with zero risk of affecting live data or real payments.
Run end-to-end test suites against the sandbox before each release — covering all integration points, error scenarios, and edge cases with reproducible test data.
Validate your YoApp integration in the sandbox and demonstrate it working before requesting production API access — speeding up the production onboarding process.
