Your business runs on API integrations that fail silently and break at the worst possible time.
An API integration built quickly is fragile: no retry logic, no error handling, no monitoring, no alerting. When it fails, operations stop and someone discovers the problem manually, hours after the fact. We build integration infrastructure that's observable, resilient, and documented.
One of your API integrations failed overnight and orders didn't process, payments didn't reconcile, or customer data didn't sync. Your team discovered it this morning. The last time this happened, it took 4 hours to identify the problem and 6 hours to remediate it.
API integrations are treated as solved problems the moment data flows correctly in the test environment. In production, the integration surface is much more complex: upstream APIs have rate limits, outages, deprecations, and breaking changes; the data they return doesn't always match the schema documented; authentication tokens expire and need renewal; webhooks are delivered out of order or duplicated; and retry storms from eager retry logic can trigger rate limiting from the upstream service.
A fragile integration is one that was built to the happy path — it works when everything goes right, and fails silently when anything goes wrong. Silent failures are the worst outcome: the payment didn't process, the order didn't route, the customer data didn't sync, and nobody knows until someone discovers the consequence hours or days later.
The businesses most exposed to this problem are those whose core operations depend on API-mediated data flows: e-commerce brands whose inventory syncs from a supplier API, logistics companies whose routing depends on carrier API data, financial services companies whose reconciliation depends on payment API webhooks, and marketplaces whose data integrity depends on consistent cross-system sync. In these businesses, an API integration failure is a business operations failure.
Robust integration infrastructure with error handling, retry logic, monitoring, and alerting — so when an upstream API has a problem, you know about it immediately, and the system recovers automatically wherever possible.
Dead letter queues
Failed API calls don't disappear silently — they're captured in a dead letter queue with the full request payload, the error response, and the timestamp. Failed records can be inspected, corrected, and reprocessed.
Exponential backoff retry logic
Rate limiting and transient errors trigger automatic retry with exponential backoff and jitter. The retry logic follows documented upstream API guidelines for each specific integration (Stripe, Twilio, and Plaid each have different retry recommendations).
Webhook signature verification
Every incoming webhook is signature-verified before processing. Stripe webhook signatures via `stripe.webhooks.constructEvent`, Plaid webhook verification via the Plaid-Verification-Id header. Unsigned webhooks are rejected.
Idempotency handling
Webhook events are idempotent — duplicate delivery of the same event doesn't produce duplicate processing. Idempotency keys are stored and checked before processing.
Monitoring and alerting
Every integration endpoint has health monitoring. Error rate spikes, latency increases, and upstream status changes trigger alerts to your on-call channel. You know about upstream problems before your customers do. Built on Next.js API routes or Node.js queue workers, Postgres, TypeScript.
One honest number to start.
Fixed-scope, fixed-price. The number below is the starting point — final scope is built from your brief.

Three steps, every time.
The same repeatable engagement on every project. No surprises, no mystery, no billable ambiguity.
Brief & discovery.
We send you questions, then get on a call. Output: a written scope with every step, feature, and integration listed.
Build & ship.
Fixed schedule, weekly reviews. No scope creep unless you change the scope — and if you do, we reprice it transparently.
Warranty & retainer.
30-day warranty on every launch. Most clients stay on a monthly retainer for ongoing features and maintenance.
Why Fixed-Price Matters Here
Integration reliability work has a defined scope: the specific integrations that need to be hardened, the specific failure modes that need to be addressed, and the specific monitoring that needs to be in place. Fixed scope, fixed price.

Harden integrations in order of operational impact if they fail. A payment integration failure is higher impact than an analytics integration failure. The audit that precedes the remediation work produces a risk-ranked list of all integrations and their current resilience posture.
Some upstream APIs are poorly designed (inconsistent error codes, insufficient documentation, unreliable behaviour under load). The integration architecture can compensate for most upstream API quality issues through defensive design — validation of all response payloads, defensive schema handling, and fallback logic for undocumented error states.
Integration code that's tied to specific API versions needs to be updated when upstream APIs change. The best mitigation is an abstraction layer between the business logic and the specific API version — when the API changes, only the adapter layer changes, not the business logic. We implement this abstraction as a standard practice.
An API integration audit and hardening project (retry logic, dead letter queues, monitoring, idempotency) across 4–8 integrations typically runs $25k–$45k. Fixed-price.
