Enterprise Integration / API Integration

API Integration Services Services

We connect your systems to the third-party APIs you depend on, such as shipping carriers, tax calculators and payment providers, with authentication, retries and error handling.

  • Retry-safeEvery outbound call backed by retry
  • 1-3 wksTypical time to connect a first
  • LoggedEvery call and failure tracked
  • ProtectedCredentials stored and rotated, never

Why It Matters

Your systems don't get to control someone else's API

Retries and fallbacks for calls that fail outside you

When a third-party API times out or returns an error, the call retries with backoff instead of failing the whole workflow, and a fallback path keeps your process moving while the issue is resolved.

  • Retry and backoff logic per external call
  • Fallback paths for failed or slow responses
  • Failures logged with enough detail to diagnose

Authentication with every third party, stored securely

Each external API gets the authentication scheme it actually requires, whether that's API keys, OAuth2 or signed requests, with credentials stored and rotated instead of hardcoded into the integration.

  • Auth matched to what each third party requires
  • Credentials stored and rotated securely
  • Usage kept within each API's rate limits

From reviewing the third party's API to a monitored connection

  1. Review the third-party API

    We check documentation, rate limits and authentication requirements before work starts.

  2. Design the integration

    Mapping which of your workflows depend on the external call, and what happens if it fails.

  3. Build the connection

    Authentication, retries and error handling are built around the third party's actual behavior.

  4. Test against real responses

    The integration is tested against real API responses, not just the happy path.

  5. Release and monitor

    The connection goes live with call volume and error rates monitored after handover.

Everything you need to connect to APIs you don't control

  • Third-party authentication

    API keys, OAuth2 or signed requests, implemented to match what the third party requires.

  • Retry and backoff logic

    Failed calls retry automatically instead of failing the whole workflow.

  • Error handling

    Failures are caught, logged and routed to a fallback instead of crashing silently.

  • Rate limit handling

    Calls stay within the third party's limits instead of getting throttled or blocked.

  • Credential management

    Keys and tokens stored securely and rotated, not hardcoded into the integration.

  • Monitoring and handover

    Call volume and error rates monitored after launch, with documentation handed to your team.

Proof

A partner API for a services company

A services company replaced email and spreadsheet requests with an OAuth-protected partner API, and went live in six weeks.

  • The challenge

    Partners asked for data by email and support keyed their records in by hand. Each new integration was a manual build.

  • The solution

    Partners read allowed data and submit records over the API with scoped OAuth credentials. Rate limits protect the systems.

  • The delivery

    Endpoints were designed around what partners request, then tested with one partner before opening to the rest.

Why teams choose TCB Infotech to connect their APIs

  • We read the third party's documentation closely

    Rate limits, auth quirks and failure modes are checked before we write a line of integration code.

  • Retries are designed, not default

    Backoff and retry behavior is matched to what actually makes sense for that specific API.

  • Credentials handled properly

    Keys and tokens are stored and rotated securely, never hardcoded into the integration.

  • We flag unreliable APIs early

    If a third party's API can't support your reliability needs, we say so before work starts, not after.

  • Direct access to the team that built it

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

API Integration, answered

What does API Integration actually involve?

We connect your existing systems to third-party APIs that already exist, such as a shipping carrier, a tax calculation service or a payment provider, handling authentication, retries and error handling for every call going out.

How is this different from API Development?

API Integration connects your systems out to APIs that already exist elsewhere. API Development goes the other way: it builds new endpoints on top of your own systems so other applications can call in. Integration wires up what already exists, development builds what doesn't.

What happens if the third-party API is down or slow?

Calls are retried with backoff, failures are logged with enough detail to diagnose, and your system keeps working on a fallback path instead of stalling on a single failed call.

How is authentication with the third party handled?

We implement whatever the third-party API requires, whether that is API keys, OAuth2 or signed requests, and keep credentials stored and rotated securely rather than hardcoded.

Can you integrate with any third-party API?

Most well-documented REST or SOAP APIs, yes. We review the third party's documentation and rate limits upfront and flag anything that would limit reliability before work starts.

What happens after the integration goes live?

We monitor call volume and error rates, fix issues that surface under real traffic, and hand over documentation covering every external service now connected.
