API Integration Services in Kenya
Connect your websites, mobile apps and business systems to the services they need — from M-Pesa and SMS to ERP, CRM, WhatsApp and custom APIs.
Make Your Business Systems Work Together
Modern businesses rely on multiple platforms — a website, a mobile app, an accounting package, a payment provider, a communication tool, and often an ERP or CRM system. When these systems are disconnected, staff spend time manually moving data between them, mistakes happen, and customers experience delays.
API integration connects your applications so they can exchange data automatically. A payment confirmed on M-Pesa updates your order system. A new lead from your website appears instantly in your CRM. An invoice created in your POS flows directly to your accounting package. These connections reduce manual work and improve the accuracy of your business data.
At Beatsy Solutions, we implement API integrations for businesses across Kenya — connecting existing systems to payment providers, communication platforms, government systems, accounting tools, and custom-built APIs. Each integration is scoped to your specific requirements and the capabilities supported by the relevant service provider.

How We Approach API Integration
A structured approach that reduces implementation risk and avoids surprises.
Requirements Analysis
We discuss your business goal, the systems involved, and what data or actions need to be exchanged.
API & System Review
We review API documentation, authentication methods, endpoints and any provider requirements or access restrictions.
Integration Planning
We define data mappings, flow diagrams, error scenarios and a testing approach before any code is written.
Development & Config
We build connection logic, data transformations, authentication handling, webhook listeners and error management.
Testing
We test against sandbox environments, validate edge cases and confirm correct behaviour under different conditions.
Deployment
We deploy to production, configure live credentials, confirm callback URLs and verify end-to-end functionality.
Monitoring & Support
Post-deployment monitoring, log review and ongoing support are available depending on project requirements.
API Integration Packages
Fixed-scope engineering tiers covering development, testing and deployment. Pricing may vary depending on API complexity, number of endpoints, authentication method, provider requirements and your existing application architecture. Third-party provider fees, API charges and transaction costs are separate from Beatsy development fees.
