Seamless Connections for Limitless Possibilities
Custom API Integrations That Connect Your Website to Your Business
Our custom API integrations connect your website or online store to the other systems your business runs on, so orders, customers, stock and leads move between them automatically instead of being copied by hand. We build integrations for WordPress, WooCommerce and Shopify websites, from payment gateways and couriers to CRMs, accounting software and WhatsApp.
Every integration starts with the job it needs to do: which data moves, in which direction, how often and what should happen when something fails. Then we connect the systems through their official APIs, such as the WooCommerce REST API, or webhooks, test with real scenarios, and log errors so problems are caught early.

I started Thirumoolar Organics because I believe in our traditional health mixes. I wanted a website that shows what we do and our products clearly. Click Worthy helped us with that. They finished the work on time, and I didn’t have any problems. I’m thankful to Click Worthy for their good work and support.

I started Nithilam Sarees in Chinnalapatti to keep our saree traditions alive. We needed a website to reach more people. Click Worthy made one for us. It’s easy for people to see our sarees and buy them. They added filters to help people find what they want. The website also works well on phones. I’m happy with the work Click Worthy did.

Custom API Integration FAQs
What is a custom API integration?
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. We review your requirements and give you a clear quote before starting.
