Enterprise Integration / API Development

API Development Services Services

Custom REST and GraphQL endpoints on top of your own systems, with authentication, rate limiting and documentation, so internal tools and partners can call in reliably.

  • 100%Endpoints documented before handover
  • 2-4 wksTypical time to a first working endpoint
  • Built-inAuthentication and rate limiting
  • VersionedEvery endpoint ships with a versioning

Why It Matters

Other systems can't call into your platform if nothing was built for them to call

Endpoints scoped to what each caller actually needs

Each endpoint is designed around a specific job, whether that's letting a mobile app read order status or letting a partner create customer records, instead of exposing raw tables that break the moment your schema changes.

  • REST or GraphQL, chosen by the use case
  • Versioned so existing callers keep working
  • Scoped to the data a caller actually needs

Authentication and rate limiting from the first endpoint

Every endpoint ships with an authentication scheme appropriate to its caller and rate limits that keep usage within agreed bounds, so a single misbehaving caller can't take the platform down for everyone else.

  • API keys, OAuth2 or JWT, matched to the caller
  • Rate limits enforced at the endpoint level
  • Usage visible before it becomes a problem

From a mapped use case to a documented, secured endpoint

  1. Map the use case

    We identify who needs to call in and what they need to read or write.

  2. Design the contract

    Endpoints, request and response shapes and error codes are defined before code starts.

  3. Build and protect

    Endpoints are built with authentication and rate limiting in place from the start.

  4. Document and test

    Every endpoint ships with documentation and is tested against real call patterns.

  5. Release and monitor

    Endpoints go live behind a version, with usage monitored after handover.

Everything you need to ship endpoints other systems can rely on

  • REST and GraphQL endpoints

    Endpoints designed around the use case, not a generic wrapper around your database.

  • Authentication

    API keys, OAuth2 or JWT, matched to who is calling in.

  • Rate limiting

    Limits enforced per endpoint so usage stays within agreed bounds.

  • Versioning

    New versions ship without breaking callers already integrated.

  • Written documentation

    Request and response formats, error codes and auth, documented for every endpoint.

  • Monitoring and handover

    Usage monitored after launch, with access and docs handed to your team.

Why teams choose TCB Infotech to build their APIs

  • We build endpoints the way we'd want to call them

    Every endpoint we ship gets the same scrutiny we'd want from an API we were integrating against ourselves.

  • Security is not an afterthought

    Authentication and rate limiting are part of the initial design, not something added after a review.

  • Documentation ships with the endpoint

    We don't hand over undocumented endpoints and call it done.

  • Versioning discipline

    Existing callers keep working when new endpoints or fields are added.

  • Direct access to the team that built it

    You reach the people who built the endpoints, not a support queue.

API Development, answered

What does API Development actually involve?

We design and build new REST or GraphQL endpoints on top of your existing systems, covering authentication, rate limiting and documentation, so other applications can call into your platform in a controlled way.

How is this different from API Integration?

API Development builds new endpoints on top of your own systems, so other applications can call in. API Integration goes the other way: it connects your systems out to third-party APIs that already exist, such as a shipping carrier or a payment provider.

Do you build REST or GraphQL?

Either, chosen by the use case. REST fits most resource-based endpoints, and GraphQL fits cases where callers need to combine several resources in one request.

How is authentication handled?

Every endpoint set ships with an authentication scheme appropriate to the caller, whether that is API keys, OAuth2 or JWT, plus rate limiting to keep usage within agreed limits.

Will the endpoints be documented?

Yes. Every endpoint ships with written documentation covering request and response formats, authentication, error codes and rate limits, so callers can integrate without back and forth.

What happens after the endpoints go live?

We monitor early usage, fix issues that surface under real traffic, and hand over documentation and access so your team can maintain the endpoints going forward.
