PHP API development that other systems can rely on
We design, build and document PHP API development projects: REST and JSON interfaces that let mobile apps, partner platforms and your own systems exchange data safely. It suits businesses that have data locked inside one application and need it available elsewhere.

- Interactive documentation your partners can read without calling us
- Versioned endpoints so a change never breaks a live integration
An API is a contract, and contracts need care
The moment a mobile app, a courier system or a partner's software depends on your endpoints, you have made promises. Field names, response shapes, error messages and behaviour under load all become things other people have built on.
Change them carelessly and someone else's checkout stops working at midnight.
Our approach is to treat the interface as a product. We agree the resources and actions first, write the specification, then build and test against it. PHP is a practical language for this: modern versions are fast and typed, frameworks such as Laravel and Symfony handle routing, validation and authentication cleanly, and your existing PHP application can often expose its data without a rewrite.
Typical requests include an API for a new mobile app, a bridge between your website and an accounting or ERP system, a public API for resellers, and a clean layer on top of an old application so a new front end can replace the old one gradually.
Situations that call for an API
Situations we see most often.
Mobile apps
iOS and Android apps need one dependable back end for logins, data and push notifications.
Partner and reseller access
Give distributors controlled access to stock, prices or orders without sharing database credentials.
System-to-system sync
Orders, customers and stock moving between your shop, ERP, courier and accounting software.
Headless front ends
A React or Vue front end, or a headless WordPress setup, reading content and data over HTTP.
Webhooks and automation
Events from payments or messaging services trigger actions in your own system.
Legacy modernisation
Wrapping an old application in an API so new parts can be built beside it.
Why trust this team with your build
For PHP API Development, projects live or die on maintainability. Here is what stands behind the delivery.
Hands-on experience
500+ websites and web applications delivered over 18+ years for clients in 48 countries, the experience behind your PHP API Development project.
Certified expertise
For PHP API Development, engineering is planned together with SEO, speed and reporting, so what ships is findable, fast and measurable rather than just finished.
Recognised work
Led by Junaid Tariq, a National Level Award Winner in Digital Marketing who also builds WordPress plugins, CRMs and web applications. See the about page.
Transparent by default
A written scope and milestones before build, code and documentation handed over at the end and hosting or domain accounts kept in your name.
Deliverables in a typical API project
Everything a developer on the other end needs, and everything you need to maintain it.
- Endpoint specificationResources, methods, parameters, responses and error codes written in OpenAPI so tools can read it.
- Authentication layerToken-based access with Sanctum, Passport, OAuth2 or JWT, chosen to match who calls the API.
- Validation and error handlingConsistent, readable error responses and strict checks on every input.
- Rate limiting and throttlingProtection against abuse and accidental loops from clients.
- Pagination, filtering and sortingPredictable ways to retrieve large collections without slow queries.
- Versioning strategyA URL or header scheme that lets old clients keep working while new ones move on.
- Automated testsFeature tests for each endpoint, including failure and permission cases.
- Documentation and sandboxReadable docs, example requests and a test environment partners can try safely.

Design choices we make with you
There is rarely one correct answer. Here is how we think about the main options.
Decision | Options | Our usual advice |
|---|---|---|
Style | REST or GraphQL | REST for most business integrations; GraphQL when many client screens need flexible queries |
Auth | API keys, OAuth2, token auth | Tokens for apps, OAuth2 for third parties, keys only for simple server-to-server cases |
Format | JSON or XML | JSON, unless a partner system demands XML |
Sync model | Polling or webhooks | Webhooks for events, polling as a fallback |
Versioning | URL path or header | Path versions are easiest for partners to understand |
Long jobs | Wait or queue | Queue and return a status, never hold a request open |
Mistakes we are paid to fix
Endpoints named after database tables rather than business actions, responses that change shape depending on the data, and errors that all return the same status code with a vague message.
An app team ships a change to a field name, the partner's integration silently fails, and nobody can say which release caused it. Versioning and a changelog are cheap at the start and painful to retrofit.
It works with a hundred rows in testing and crawls with real data. We test with realistic volumes before consumers connect.
None of this is exotic, which is why a checklist-driven review catches most of it.
If your current interface shows any of these, our PHP code audit and optimization service is a sensible first step.
Build sequence
We work contract first, code second.
- Consumer interviewsWe speak with whoever will call the API: your app team, a partner developer, an internal analyst.
- SpecificationEndpoints and payloads are drafted in OpenAPI and reviewed with you and consumers before coding.
- Core buildModels, controllers, resources and authentication are developed with tests alongside.
- Security passWe check permissions per endpoint, mass assignment, injection risks and token handling.
- Sandbox and documentationA test environment and published docs let consumers integrate in parallel.
- Release and monitoringLogging, error alerts and usage tracking go live with the first consumer.
Security you can explain to an auditor
Most API breaches come from ordinary mistakes: an endpoint that returns another user's record when the ID is changed, a token that never expires, verbose errors that reveal the database.
Rate limits and clear error responses protect both sides.
For a fuller treatment of the approach, read our guide on how to build a secure PHP API.
Check the current rules for your sector and country before storing anything sensitive, and tell us early if you operate under a specific regulation so we can design for it.
Factors behind API quotes
We quote from the specification. These are the factors that matter.
Number of endpoints
Count of resources and the actions allowed on each.
Business rules behind them
An endpoint that only reads data is cheap. One that triggers pricing or stock logic is not.
Consumers
Public APIs need stricter versioning, docs and support than a private one for your own app.
Third-party dependencies
Each outside service called from your API adds failure handling.
Existing code
Wrapping a tidy application is quicker than untangling a messy one first.
Support expectations
Partner-facing APIs usually need monitoring and a response process.
Cases that need no custom API
WooCommerce, Shopify and most accounting tools ship usable interfaces, and building another layer over them rarely adds value.
We also advise against an API when only one internal screen needs the data, because a plain database query inside the application is simpler.
If you are still weighing Laravel against other stacks for the work, see Laravel API development and the broader API development and integration service.
Building for Pakistani and overseas integrations
Courier services, bank and wallet gateways and WhatsApp business providers each publish documentation of different quality, and some change without much notice.
We build an adapter layer around each, so that a provider change touches one file instead of the whole application, and we log every outbound call to make failures easy to diagnose.
For clients abroad we work with the usual ecosystem: Stripe, PayPal, Twilio, SendGrid or Mailgun, Google and Microsoft sign-in, and cloud storage.
Time zones are handled explicitly in the data model, because an order created at night in Karachi and read in New York should show the same moment to both.
Quality you can inspect
Instead each API ships with an automated test suite you can run, a published specification you can compare against actual behaviour, and logs that show response times and errors in your own environment.
If we need to ask a question that the docs should have answered, the docs are rewritten.
For Pakistani businesses connecting to couriers, payment providers or WhatsApp business tools, we read the provider's current documentation at build time, because these interfaces change and we do not rely on memory.

Frequently asked questions
Straight answers before you get in touch.
What is the difference between a REST API and GraphQL?
REST exposes fixed resources at set URLs and suits most integrations. GraphQL lets a client ask for exactly the fields it needs, which helps complex front ends. We recommend REST unless you have a clear reason for GraphQL.
Can you build an API on top of our existing PHP application?
Usually yes. We add a controlled layer that reuses existing models and rules, then test that it exposes only what it should. A review through PHP code audit and optimization may come first if the code is fragile.
How do you handle authentication?
It depends on who calls the API. Mobile apps typically use token auth, third parties often use OAuth2, and simple server calls may use scoped keys. We explain the trade-offs and pick the lightest option that is still safe.
Will you document the API?
Yes. Documentation is a deliverable, not an optional extra. You receive an OpenAPI specification and readable examples, and we can host an interactive reference.
Can the API support a mobile app you are not building?
Yes. We work with your app team directly, agree the contract first and provide a sandbox so they can build in parallel. Our PHP web application development team can add the admin side.
