One payment API for
all your websites & apps
Connect any number of sites and mobile apps to PayChangu through a single secure backbone. Each project gets its own unique API key.
Unique API Keys
Every website or mobile app gets its own secret key. Identify and secure traffic per project.
Minimal Integration
Just one POST request with an X-API-Key header. 10 lines of code is enough.
Automatic Webhooks
PayChangu notifies the backbone → we verify → we push the result to your site’s webhook.
Central Dashboard
See all registered sites, transactions, and revenue in one place. Toggle sites on/off instantly.
How it works
Three simple steps from zero to accepting payments
Register your site or app
Go to the Admin Dashboard → Register Site. Give it a name and optional webhook URL. You receive a unique api_key.
Call /api/initiate from your backend
Send amount, customer email, return_url and the X-API-Key header. You get a checkout_url back.
Redirect the user & receive the result
Send the customer to PayChangu. When they finish, we verify the payment and optionally notify your webhook so you can unlock the product.
