API Integration Services

Make your stack talk to itself.

Production integrations between the SaaS tools your business already pays for — Salesforce, HubSpot, NetSuite, Slack, Zendesk, Stripe — and the long tail of internal APIs. Reliable, observable, recoverable. Not duct tape.

Your systems1

Your systems

Your database, app, and the internal APIs only you have.

The integration layer2

The integration layer

Auth, retries, idempotency, mapping, and monitoring — built once, properly.

The tools you run on3

Salesforce, HubSpot, NetSuite, Slack, Zendesk, and the rest.

01The idea

An integration is easy to demo and hard to trust.

Anyone can wire two APIs together for a happy-path demo. The hard part is the day the upstream service is slow, the webhook arrives twice, a field gets renamed, or a record is deleted on one side and not the other. That's where most integrations quietly rot — and where ours are actually engineered. We build the boring, durable layer underneath: retries with backoff, idempotency, replay, and monitoring, so the connection keeps its promises long after the demo.

What we connect

If it has an API — or a halfway-decent export — it can join the system.

  • 01

    CRM ↔ your product

    Pipeline, accounts, and usage kept in step both ways.
  • 02

    Billing ↔ accounting

    Stripe and your ledger reconciled, not re-keyed.
  • 03

    Support ↔ customer data

    Zendesk and Intercom with the context already attached.
  • 04

    Ops ↔ internal APIs

    The bespoke systems no off-the-shelf connector covers.
  • 05

    Marketing ↔ product events

    HubSpot and your app firing on real behaviour.
  • 06

    Data ↔ the warehouse

    Fresh, modelled data instead of nightly CSV dumps.

Reliable, observable, recoverable.

The integration keeps running — and tells you the moment it doesn't.

02Why ours hold up
Rate-limit handling

Rate-limit handling

We respect every provider's limits and back off with jitter, so a burst never drops data.

Retries with backoff

Retries with backoff

Transient failures are expected; the system retries intelligently instead of giving up.

Idempotency

Idempotency

The same event can arrive twice and never double-creates an order or a charge.

Replay & monitoring

Replay & monitoring

Inspect any record, replay what was missed, and get alerted before customers notice.

The work behind a connection that just works.

03How we work
1

Map the flow

Which system owns which field, how often it changes, and where it breaks today.

2

Design the contract

Auth, mapping, and the failure modes — decided before a line is written.

3

Build the reliable layer

Retries, idempotency, replay, and monitoring around the integration.

4

Backfill & verify

Reconcile history, prove the edges, and watch it under real load.

5

Operate & alert

Hand over an operator view and alerts so it stays trustworthy.

Questions teams ask first.

We start by drawing the actual flow — which system owns which field, how often it changes, and where the current sync silently drops things. Most broken integrations aren't broken everywhere; they fail on a specific edge (a rate limit, a renamed field, a record that was deleted on one side). We find that edge first, then build the integration around handling it, rather than re-running a full sync and hoping.

Two systems that should be talking?

Tell us which tools are out of sync and where the data hurts. We'll map the flow and build the integration that keeps them honest — with the retries, idempotency, and monitoring that make it last.
