Business workflow APIs
APIs can power quote calculators, booking workflows, project status, inventory lookups, customer dashboards, form processing, or other defined business actions.
Custom API Development
Backend APIs that do useful work
without trusting the browser.
An API is not the same thing as a WordPress plugin. APIs expose controlled server-side operations or data to websites, apps, integrations, and other services. I can build defined REST endpoints, webhook receivers, integration layers, and backend workflows with security controls chosen for the actual business risk.
What I can build
Useful first.
Custom where it matters.
Third-party integrations
A custom backend can connect supported services while keeping API keys and privileged operations on the server instead of exposing secrets in browser code.
Webhook receivers
Payment, order, booking, shipping, or other event webhooks can be verified, validated, made replay-aware where appropriate, and processed through controlled server-side state changes.
Protected data APIs
Endpoints that expose customer or business data can use authentication, object-level authorization, role/function checks, response filtering, rate limits, and safe error behavior appropriate to the data.
Upload and processing APIs
File-handling endpoints can enforce file type, size, count, authentication, authorization, storage, and workflow restrictions rather than trusting the filename or client request.
API documentation and testing
Defined request/response contracts, failure cases, authorization rules, and abuse tests make the API easier to maintain and safer to integrate than undocumented endpoints.
How I approach it
API security starts with authorization and trust boundaries, not a hidden URL.
For API work, I use the OWASP API Security Top 10 and OWASP ASVS as references alongside platform-specific requirements. The exact controls depend on whether the API handles public data, customer records, payments, uploads, administrative actions, or third-party services.
Common controls can include server-side authentication and authorization, object-level access checks, allow-list validation, bounded request sizes, output shaping, rate limiting, idempotency/replay protections, signed webhook verification, least-privilege service credentials, secret isolation, safe logging, and dependency review.
An OWASP-informed build is not the same as promising that an API is impossible to exploit. The responsible goal is to reduce attack surface, verify sensitive controls, test abuse paths, and keep high-risk operations authoritative on the server.
Common questions
Before we
start building.
What kinds of APIs can you build?
Defined REST APIs, authenticated CRUD/business endpoints, quote/booking workflows, webhook receivers, inventory/order synchronization, customer-facing data APIs, server-side integrations, and other clearly scoped backend functions are good candidates.
Can an API power a website feature?
Yes. A website can call an API for data or actions while the API keeps privileged logic, credentials, validation, and authorization on the server.
Do you build payment APIs?
I can integrate supported payment-provider APIs and secure webhook/payment-state workflows. Raw card-number handling should normally stay with established payment processors rather than being collected by custom site code.
How do you secure an API?
The controls depend on the endpoint. Typical areas include authentication, object/function authorization, input schemas, request-size limits, rate limiting, safe errors, response filtering, CORS where relevant, signed webhooks, replay/idempotency handling, secret management, logging, and dependency review.
Is an API the same as a WordPress plugin?
No. An API is an interface for systems to exchange data or trigger operations. A WordPress plugin extends WordPress itself. A plugin can call or expose an API, but they are different pieces of software.
