Third-Party API Integration

We connect websites and applications to third-party APIs — payment processors, shipping carriers, CRMs, mapping services, and other external platforms your business already relies on.

Every API is different, so the work starts with reading the provider's documentation carefully and understanding authentication, rate limits, and data formats before writing any integration code. We build integrations with proper error handling so a slow or failed API response doesn't break your site, and we test against the provider's sandbox environment before connecting to live data.

API Research & Planning

Reviewing the target API's documentation, authentication method, and rate limits before building anything.

Secure Authentication Handling

Implementing API keys, OAuth, or tokens correctly, with credentials kept out of your codebase.

Error Handling & Fallbacks

Building integrations that fail gracefully — a slow or down third-party API shouldn't take your whole site down with it.

Sandbox Testing Before Go-Live

Testing thoroughly against the provider's sandbox or staging environment before connecting to live, production data.

How it Works

Requirements & API Review

We identify which API or APIs you need connected and review their documentation, limits, and data structure.

01

02

Build & Sandbox Test

We build the integration and test it thoroughly in the provider's sandbox environment before touching live data.

Go-Live & Monitoring

We switch to production credentials, verify real data flows correctly, and confirm error handling works as expected.

Frequently Asked Questions

Most well-documented REST or GraphQL APIs — including CRMs, shipping carriers, payment processors, mapping services, and internal business tools. Tell us which platform you need and we'll confirm feasibility.
We build integrations with error handling so a failed API call degrades gracefully rather than breaking your site — the specific fallback behavior depends on what the integration does.
It depends on the complexity of the API and how much data needs to flow through it. Simple integrations can move quickly; ones involving multiple endpoints or complex data mapping take longer.
It depends on the API's complexity and how much custom logic is needed around it. Contact us for a quote once we know which integration you need.
Access credentials or a sandbox account for the API in question, and a clear idea of what data or action needs to flow between the two systems. We'll flag anything else once we've reviewed the provider's documentation.
Initial testing and go-live support is included. Since providers do change their APIs over time, ongoing monitoring or maintenance can be arranged separately if you want us to keep watching it long-term.

Before Writing Code

Mapping The Integration Before Building It

Every third-party API has its own quirks around pagination, rate limits, and webhook versus polling behavior, and we document these specifics for your exact integration before writing a line of connection code. This upfront mapping also covers what happens to your existing workflows if a field or endpoint changes on the provider's side, so the integration doesn't quietly break later.

  • Pagination, rate limits, and webhook behavior documented up front
  • Provider-side change scenarios planned for before build starts

Monitoring And Maintaining Live Integrations

APIs change — providers deprecate endpoints, rotate authentication methods, and adjust rate limits over time, so a live integration needs periodic checking rather than a set-and-forget approach. We can set up basic logging and alerts so a failed API call gets noticed quickly instead of silently dropping data, and revisit the integration if the provider announces breaking changes.

  • Integrations revisited when providers announce breaking changes
