Earnipay

Earnipay is a Nigerian fintech that operates an NRS/FIRS-compliant e-invoicing platform for businesses. As an accredited Nigeria Revenue Service (NRS) and NITDA systems integrator, Earnipay lets developers programmatically create businesses, manage customers and products, generate FIRS-compliant invoices with IRN (Invoice Reference Number) and QR codes, and submit them to the tax authority through an Access Point Provider (APP) connection. The public Earnipay Invoicing API is an OpenAPI 3.0.0 REST service covering authentication, businesses, customers, products, payment details, invoices, IRN and QR generation, bank lookup/verification, and team management. It authenticates with JWT bearer tokens for user-facing flows and an X-API-Key header for third-party integrations. Added to the API Evangelist network as a portfolio company of Canaan Partners.
