An API (application programming interface) lets two systems exchange data. A custom API integration connects your website to another system, such as a CRM, courier or accounting tool, so information moves automatically without manual copying. Can you integrate WooCommerce with my ERP or accounting software? Usually, yes. If your ERP or accounting software has an API or import feature, we can sync orders, customers, invoices and stock with WooCommerce through the WooCommerce REST API and webhooks. Can you connect Shopify to Indian payment gateways and couriers? Yes. Shopify supports Razorpay and other Indian gateways, and couriers such as Shiprocket integrate through apps or their APIs. We set these up and add custom connections where an app does not do what you need. Do you integrate WhatsApp with websites? Yes. We add WhatsApp chat buttons, and use the WhatsApp Business Platform through approved providers to send order confirmations, shipping updates and enquiry alerts. What happens if an integration fails? We build in error handling and logging, so failed syncs are retried or flagged rather than silently lost, and we can monitor integrations as part of a support plan. How much does a custom API integration cost? It depends on the systems involved, the amount of data and whether ready-made connectors exist.
