Connect Your Systems to the APIs You Already Need
We connect your systems to the third-party APIs you already depend on, shipping carriers, tax calculators, payment providers, with authentication, retries and error handling built in so external calls stay reliable.
50+ ERP and software projects. Zero failed projects since 2021.
Your systems don't get to control someone else's API
A shipping carrier, a tax engine or a payment processor runs its own API on its own terms: its own uptime, its own rate limits, its own error format. API Integration is the work of wiring your systems into those external APIs so a slow or failed call out there doesn't turn into an outage in here.
Retries and fallbacks for calls that fail outside your system
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 and rotated 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.

Every third-party service tracked in one place
Illustrative example. Your actual connections depend on the third-party services you rely on.
From reviewing the third party's API to a monitored connection
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.

Start Connecting Your APIs
A workflow that depends on a third-party API is only as reliable as the integration handling its failures. Book a free consultation and tell us which external services you need connected.

How We Connect Your APIs
From reviewing the third party's documentation to a monitored, resilient connection. Here is the process behind every integration we build.
Review, build and monitor, in that order
The third party's real behavior, understood before we build
We read the third party's documentation, check its rate limits and test its actual responses before writing any integration code, so surprises show up early instead of after launch.
- Documentation and rate limits reviewed upfront.
- Authentication requirements confirmed early.
- Failure modes flagged before work starts.

Retries, error handling and authentication matched to that API
Retry and backoff behavior, error handling and authentication are all built to match how that specific third-party API actually behaves, not a generic template applied to every integration.
- Retry and backoff logic per external call.
- Errors caught and routed to a fallback.
- Credentials stored and rotated securely.

Call volume and errors tracked after the connection goes live
Once the integration is live, we track call volume and error rates, fix issues that surface under real traffic, and hand over documentation covering every connected service.
- Call volume and error rates tracked post-launch.
- Issues fixed as they surface under real traffic.
- Documentation handed to your team.
