Third-Party API Integration
Modern applications rely on dozens of external services — shipping providers, email platforms, analytics tools, mapping services, identity verification, and more. Anubiz Labs integrates third-party APIs into your application with proper authentication, error handling, rate limit management, and monitoring so these external dependencies enhance your product instead of becoming liabilities.

Integration That Handles Real-World Conditions
Third-party APIs are unpredictable. They go down without warning, return unexpected error codes, change response schemas between versions, and impose rate limits that vary by plan tier. A naive integration that assumes the happy path will eventually break in production and take your application's functionality with it.
We build integrations that handle every realistic failure scenario. Circuit breakers prevent cascade failures when an external service is down. Retry logic with exponential backoff recovers from transient errors without overwhelming the remote API. Response validation catches schema changes before they corrupt your data. Fallback strategies maintain basic functionality even when a third-party dependency is completely unavailable.
Every external API call is logged with request details, response data, latency measurements, and error information — giving you complete visibility into how third-party services perform within your application.
Authentication and Credential Management
Third-party APIs use a bewildering variety of authentication schemes — API keys, OAuth 2.0 with various grant types, HMAC signatures, mutual TLS, custom headers, and proprietary token systems. We implement each authentication flow correctly and securely, with automatic token refresh, credential rotation support, and encrypted secret storage.
For OAuth integrations, we handle the full lifecycle: initial authorization, token exchange, refresh token management, scope changes, and re-authorization when tokens are revoked. Your users connect their accounts once and the integration maintains the connection indefinitely without manual intervention.
Rate Limiting and Cost Optimization
Many third-party APIs charge per request or impose strict rate limits. We implement intelligent request management that minimizes API calls through caching, batching, and deduplication. Frequently requested data is cached with appropriate TTLs so your application stays responsive without burning through API quotas.
For rate-limited APIs, our implementations track consumption in real time and throttle requests to stay within limits. When limits are reached, requests queue and execute as capacity becomes available rather than failing with rate limit errors. Priority queues ensure that critical operations execute first when capacity is constrained.
Usage dashboards show exactly how many API calls each feature consumes, making it easy to identify optimization opportunities and forecast third-party costs as your application scales.
Abstraction Layers for Vendor Flexibility
Tight coupling to a specific third-party API makes it expensive and risky to switch providers later. We build abstraction layers that isolate your application logic from specific vendor implementations. If you decide to switch email providers, mapping services, or payment processors, only the adapter layer changes — your application code stays untouched.
These abstraction layers also make testing straightforward. Mock implementations replace real API calls in test environments, so your test suite runs fast, deterministically, and without consuming API quotas or requiring network access.
