API Integrations & Connectors

API integrations that keep every system in sync

We design custom APIs and build connectors between your CRM, ERP, eCommerce platform, property portals and internal tools — two-way, idempotent and monitored, so data arrives once, in the right shape, even when a provider has a bad day.

When integration becomes the bottleneck

  • 01

    The same customer or product lives in three systems — with three versions of the truth.

  • 02

    A nightly CSV export is the only thing holding two critical systems together.

  • 03

    A partner API changed and orders stopped syncing for days before anyone noticed.

  • 04

    Partners want access to your data, but you have no secure, documented API to give them.

Capabilities

Integration engineering, end to end

From API design to the 3 a.m. retry — we own the whole path your data travels.

Custom API design

REST and GraphQL APIs with OpenAPI specs, versioning, authentication and rate limits — documented for partners and developers.

Third-party connectors

Production connectors for CRMs, ERPs, eCommerce, payment and marketing platforms, and industry portals.

Two-way data sync

Bidirectional sync with field mapping, conflict resolution and a clear source of truth for every entity.

Webhooks & event streaming

Real-time updates through webhooks and queues instead of polling, with signature verification and replay.

Resilience at volume

Idempotency keys, retries with back-off, rate-limit handling and dead-letter queues for high-volume traffic.

Integration monitoring

Dashboards and alerts for sync lag, error rates and rejected payloads, with every message traceable end to end.

Use cases

Integrations we build

Real estate

Portal syndication

Listings published once and syndicated to property portals and your website, with portal leads flowing back into the CRM.

eCommerce

Orders, stock and invoicing

Orders, inventory and customers synced between store, warehouse and accounting, so stock and revenue always match.

SaaS

A public partner API

A secure, documented API with webhooks that lets customers and partners integrate with your product on their own.

Sales & marketing

One CRM, one source of truth

Contacts and activity from forms, ads, email and calls consolidated into one CRM — deduplicated and attributed.

Process

How we deliver an integration

  1. 01

    Systems & data audit

    We inventory systems, APIs, limits and data owners, and define the source of truth for each entity.

    Deliverable: Integration map

  2. 02

    Contract & mapping

    API contracts, field mappings and error semantics agreed before any code — including what happens on conflict.

    Deliverable: OpenAPI spec & mapping sheet

  3. 03

    Build & load-test

    Connectors built against sandbox accounts, replayed with real payloads and tested at peak volume.

    Deliverable: Tested connectors

  4. 04

    Operate

    Monitoring, alerting and handling of provider changes and API version upgrades over time.

    Deliverable: Dashboards & runbook

FAQ

API Integrations & Connectors: your questions, answered

Didn’t find yours? Ask us directly.

What if the system we use has no API?

We work with what's there — webhooks, database replication, file drops, email parsing or, as a last resort, controlled browser automation — and wrap it in a proper API so the rest of your stack doesn't have to care.

How do you prevent duplicated or lost data?

Every write is idempotent, every message carries a unique key, and failed messages go to a dead-letter queue for replay instead of disappearing. Reconciliation jobs compare both sides and flag drift.

Can you handle high volumes and API rate limits?

Yes. We batch, queue and throttle requests to each provider's limits, scale workers horizontally and backfill history without affecting live traffic.

Who maintains the integration when a provider changes its API?

We can. Monitoring catches breaking changes early, and under a managed plan we handle version upgrades, deprecations and credential rotation for you.

Are integrations secure and GDPR-compliant?

We transfer only the fields each system needs, encrypt data in transit and at rest, keep credentials in a secrets vault and host data in the EU when required.
