What is the Merchant Integration API?
The Merchant Integration API lets your systems — an ecommerce site, ERP, POS, or custom backend — create and manage Wasal delivery orders programmatically. Everything you can do from the merchant dashboard, you can do over the API:
- Create and look up customers and their addresses
- Get live delivery-fee pricing per area
- Create delivery orders and track them in real time
- Cancel orders and read their full status history
- Generate printable shipping labels
All endpoints live under the /integration/merchant/ prefix and authenticate with a single API key.
