Services Custom REST & GraphQL API Development
.
APIs that work cleanly and integrations that actually connect. REST and GraphQL APIs built properly, and third party tools wired into your system.
Modern applications run on connections. Your site talks to a payment provider, your CRM talks to your admin panel, your mobile app talks to your backend. I build the APIs that make these connections clean and reliable, and I integrate the third party services your business depends on. This covers custom REST and GraphQL APIs, payment gateways, webhooks, and connecting CRMs and other tools to Laravel, WordPress or Strapi. The focus is on APIs that are well documented, consistent and safe to build on.

- Custom REST APIs for web, mobile and external tools
- GraphQL APIs when a flexible query interface fits better
- Payment gateway and billing integrations
- Webhooks to push events to your systems in real time
- Connecting CRMs, email, analytics and other third party tools
- API authentication, rate limiting and versioning done properly
- Documentation so your team and other developers can actually use it
.
I start by defining what the API needs to do and who will use it. That shapes the endpoints, the data shape and how authentication works. Then I build it with versioning and error handling from the start, so later changes do not break existing consumers. For integrations, I map how data should flow between the tools before writing any code, so the connection is reliable rather than fragile.
.
A messy API is expensive. Every consumer built against it has to work around its problems, and every integration you add later becomes harder. A well designed API and clean integrations mean new features, new tools and new partners connect without rework, which saves real time and money as your product grows.

FAQ.
Do you build APIs for existing systems or only new ones?
Both. I can build an API layer on top of an existing Laravel, WordPress or Strapi system, or design one from scratch for a new product.
Which payment providers can you integrate?
I have experience with the common payment gateways used in web applications. Tell me the provider and region and I will confirm the details before quoting.
What does API documentation include?
Endpoints, request and response examples, authentication details and error handling. Clear enough that another developer can integrate without asking you questions.
Can you integrate multiple tools together?
Yes. Connecting several systems, like your site, CRM and analytics, is often where the real value is. I map the data flow so everything stays consistent.
