Service

APIs and integrations built to fail safely, not silently

Most integration problems don't show up on day one — they show up months later, when a third-party API changes its response format or rate limits a burst of requests during your busiest period. We build APIs and integrations with explicit error handling, retries, and monitoring from the start, so failures are visible and recoverable instead of silent.

Business problems this solves

  • Two or more systems need to share data but don't currently talk to each other
  • An existing integration fails silently and problems are only noticed when a customer complains
  • A public or partner-facing API needs to be built and documented
  • Rate limits or authentication requirements from a third-party service are causing reliability issues

Core deliverables

  • A documented API with clear versioning and authentication
  • Integration with the specific third-party systems your business depends on
  • Retry logic and error handling for calls to unreliable or rate-limited services
  • Monitoring and alerting so integration failures are caught immediately

Key features

RESTful or GraphQL APIs, chosen based on how the data is consumed
Webhook handling for real-time updates from third-party platforms
Rate limit and quota management for outbound API calls
API documentation generated and kept in sync with the implementation

Our process for this service

Step 1

Map the systems and data flow

We document what data needs to move where, and how often, before designing the integration.

Step 2

Design for failure, not just the happy path

Retry logic, timeouts, and fallback behavior are designed alongside the core integration, not added afterward.

Step 3

Build and test against real third-party behavior

Testing includes rate limits, malformed responses, and downtime scenarios, not just a clean sandbox environment.

Step 4

Monitor after launch

Integration health is monitored so failures are caught immediately rather than discovered through a customer complaint.

Benefits

  • Integration failures surfaced through monitoring instead of customer complaints
  • Systems that stay in sync without manual data re-entry
  • A documented API partners and internal teams can build against confidently
  • Reliability that holds up under rate limits and third-party outages

Frequently asked questions

In most cases, yes — we evaluate the target system's API during discovery and flag any real limitations before committing to a scope.
