API Development

An API is the contract between your system and everything else that needs to talk to it: your mobile app, a partner's platform, an internal service, or a future product you have not built yet. A good API is predictable, documented, secured, and versioned, so the people building against it can rely on it without asking. A poor one leaks data, breaks every client when it changes, and becomes the part of the system nobody wants to touch.

We build REST APIs on Laravel, using Sanctum or Passport for authentication depending on what the API needs to support. Sanctum suits first-party mobile apps and single-page applications, while Passport fits cases where third parties need OAuth access on behalf of your users. The OpenAPI documentation is generated straight from the code, so the docs describe exactly what is deployed rather than what someone remembered to update.

The most common reasons UAE and GCC businesses come to us for API work are powering a mobile app, sharing data with a partner such as a logistics provider, marketplace, or bank, connecting internal systems that currently exchange spreadsheets, and opening up an existing platform so customers or resellers can integrate with it. We also build the API layer for every mobile app we develop, so the same team is responsible for both ends of the connection.

Our process starts with the consumers of the API rather than the database. On calls with your team and, where possible, the partner or app developers who will use it, we identify who is calling the API, what they need to do, how often, and with what level of access. Your strategist writes this up as a set of resources and operations, along with the authentication model and any rate limits. We agree naming conventions, error formats, and pagination rules at this stage, because changing them later breaks clients. The scope is quoted at a fixed price before development begins.

The build follows a consistent pattern. Every endpoint validates its input, checks authorisation against the specific record being requested rather than just the user's login, returns data through a defined resource format so internal fields are never exposed by accident, and returns errors in the same structure everywhere. Endpoints are covered by automated tests that run on every change, so a fix in one place does not silently break another. Versioning is designed in from the first release, which means a future change can be introduced as a new version while existing apps keep working.

For partner integrations we pay particular attention to webhooks, idempotency, and logging. If a partner sends the same request twice because of a network timeout, the second request should not create a duplicate order. If an outgoing webhook fails, it should retry and be visible in a log. These details are what separate an API that works in a demo from one that works on a busy Friday.

What you receive is a deployed, documented API, generated OpenAPI documentation your developers and partners can read or import into their own tools, an automated test suite, a versioning and deprecation approach written down, sample requests for the main workflows, and the source code in your own repository. If a mobile app or partner is building against the API at the same time, the delivery lead coordinates with them directly.

The pitfalls are well known and still common. Returning entire database records instead of shaped responses, which exposes fields that were never meant to leave the server. Checking that a user is logged in but not that they are allowed to see the specific record. Shipping without versioning and then being unable to change anything. Writing documentation once by hand and letting it drift. And treating rate limiting and logging as optional until a partner integration floods the system.

Timelines depend on the number of resources and the complexity of the rules behind them. An API supporting a focused mobile app or a single partner integration is usually a matter of weeks. A broader public or partner API with OAuth, webhooks, and multiple versions is planned in phases. We share the phase plan and what each one includes during scoping.

If you need an API for an app, a partner, or your own systems, book a call and bring the list of who needs to connect. We will turn it into a contract that holds.
