Payments and billing
Payment gateways, wallets, invoices and subscriptions connected to your store or app, with confirmations and refunds handled automatically.
When your website, store, booking system and accounting software do not talk to each other, your team becomes the bridge, retyping orders, chasing payments and fixing mistakes. We build secure API integrations that move data between your tools automatically, so work happens once and everything stays in sync.
An API is the doorway that lets software talk to other software. An integration uses those doorways so a new order can reach your accounting system, a booking can trigger a WhatsApp message, and a website form can drop a lead straight into your CRM.
The result is fewer mistakes, faster response times and hours of manual work returned to your team every week. We design every integration to be secure, reliable and easy for you to understand.
Payment gateways, wallets, invoices and subscriptions connected to your store or app, with confirmations and refunds handled automatically.
Courier rates, label printing and live tracking sent to customers, so orders leave your warehouse without manual entry.
Leads from your website, ads and forms created in your CRM instantly, with the right owner, tags and follow up reminders.
Orders, invoices and inventory flowing into your accounting and stock systems without double entry.
WhatsApp Business, SMS and email messages for bookings, orders and reminders, sent at the right moment.
Google services, ad platforms and email tools linked up so your reports and campaigns use the same trusted data.
The best approach depends on how much data you move and how critical it is. If a simple tool already does the job, we will tell you. When it does not, a custom integration is the safer long term choice.
| Manual copy and paste | No code automation tools | Webzelia custom integration | |
|---|---|---|---|
| Reliability | Depends on people being careful | Good for simple tasks | Built with error handling and monitoring |
| Complex rules | Handled by hand | Limited by the tool | Any logic your business needs |
| Cost over time | Staff hours every week | Fees grow with volume | One build, light maintenance |
| Security | Data in many inboxes and files | Data passes through a third party | Keys protected, access limited, activity logged |
| Ownership | None | Tied to the tool | You own the code and documentation |
These are examples of what we regularly connect. If your tool is not listed, send us its name and we will check how it can be integrated.
Connect orders, payments, stock and shipping so every sale flows from checkout to delivery.
Link bookings, reminders and invoices for clinics, gyms, salons and agencies.
Build the APIs and connections your product needs to work with customers and partners.
Bring leads, sales and reports together in one place instead of five.
A membership and booking web app for a gym chain across three cities, integrated with their point of sale system.
A custom React dashboard for a fintech startup that replaced three spreadsheets and cut reporting time from days to minutes.
We review your tools and your workflow, map where data should move, then send a written plan and fixed quote within three days.
We decide how each system will authenticate and exchange data, and agree the rules for what happens when something goes wrong.
We build the integration and test it in a safe environment with real scenarios before it touches your live data.
We go live, set up alerts, document everything and stay on hand for thirty days, with monitoring plans if you want ongoing care.
The dashboard they built replaced three spreadsheets our team used daily. It just works, and when we need a change they turn it around in a day or two.
They rebuilt our checkout and mobile orders went up almost immediately. I finally understand what my website is doing each month.
An API integration connects two or more software tools so they can share data automatically. For example, your online store can send new orders to your accounting software, your booking system can message customers on WhatsApp, and your website form can create a lead in your CRM without anyone retyping anything.
The price depends on how many systems are involved, how complex the data is and whether the services offer a well documented API. After a free call we scope the work and send a fixed written quote, so you know the cost before we begin.
A simple integration, such as connecting a form to a CRM or a payment gateway to a store, can take a few days to two weeks. Larger projects that connect several systems or need custom logic take longer, and we confirm the timeline in writing.
We can integrate any service that offers an API. Common examples include payment gateways, courier and shipping services, CRMs, accounting software, email and SMS platforms, the WhatsApp Business API, Google services, social media platforms and point of sale systems.
Often yes. If your software has an API, we use it. If it does not, we can build a secure bridge, a custom API layer or a scheduled data sync, and we tell you honestly if a different approach would be cheaper or safer.
We store keys and secrets outside the code, use encrypted connections, limit access to only the data each connection needs, and log activity so problems are easy to trace. We also follow the security rules of each service we connect to.
Services update their APIs from time to time, which can break an integration. We build in error handling and monitoring so problems are caught early, and our maintenance plans cover updating your integrations when providers make changes.
Yes. We design and build secure REST APIs with clear documentation, so your website, mobile app and partners can all use the same data safely.
No code tools are great for simple workflows and we are happy to recommend them when they fit. A custom integration is better when you need reliability at scale, complex rules, tighter security, lower long term fees or full control over your data.
Yes. Every project includes thirty days of free support after launch, and after that you can choose a monthly plan that covers monitoring, fixes and updates to your integrations.
