API & Integration Automation

Make the software you already pay for actually talk to each other, reliably, with failures that alert instead of silently dropping data.

What this is

We build and maintain the integration layer between your systems — CRM, billing, support, ecommerce, internal tools — so data moves automatically and correctly, with monitoring and error handling that surfaces problems instead of losing them quietly.

Who it's for

  • Companies running 5+ SaaS tools that should share data but don't
  • Teams that have tried native integrations or Zapier and hit a wall on complexity or reliability
  • Businesses that need a custom API build against a vendor with no off-the-shelf connector

The problem

Most SaaS tools have an API, but 'has an API' and 'reliably integrated with your other systems' are very different things. Native integrations are often shallow, and no-code tools hit limits fast on anything with real logic or volume.

What it automates

  • Bi-directional data sync between CRM, billing, support, and ecommerce platforms
  • Custom integrations against vendors with no off-the-shelf connector
  • Webhook-driven real-time updates instead of slow polling
  • Data transformation/mapping between systems with different schemas

How it works

1

System audit

Map what data needs to move where, how often, and what happens today when it doesn't.

2

Integration design

Choose the right approach per connection — direct API, webhook, or an orchestration layer — rather than forcing one tool to do everything, following established resource-oriented API design practices like Google's API design guide where it applies (see: https://docs.cloud.google.com/apis/design).

3

Build with error handling

Every integration point gets retry logic, timeout handling, and alerting on failure, not a silent drop — mirroring the reliability practices vendors document for production webhook handling, such as Stripe's guidance on retries and signature verification (see: https://docs.stripe.com/webhooks).

4

Monitor

Ongoing visibility into integration health, so a broken sync gets caught in hours, not discovered a month later in bad data.

What it integrates with

Any system with a documented APIMake.com, n8n as orchestration layersWebhooks and event-driven architecturesCustom API builds for undocumented/legacy systems

What implementation involves

Audit (3-5 days)

Map data flows and failure points across current systems.

Build (1-4 weeks per integration)

Integration build with retry/error handling.

Testing

Load and failure-mode testing before production traffic.

Monitoring setup

Alerting on sync failures, dashboard for integration health.

Limitations — honestly

  • Bound by what the third-party API actually exposes — some vendors have limited or rate-capped APIs
  • Real-time sync isn't always possible depending on the vendor; we're explicit about latency where it applies
  • Requires ongoing monitoring, since vendor APIs change without warning

Realistic outcomes

  • Eliminates manual data re-entry between systems
  • Failures get caught and alerted instead of silently corrupting data
  • New tools can be added to the stack without a fresh integration project each time

Frequently asked questions

We evaluate alternatives case by case — some vendors support integration via partner programs, others require different approaches; we're upfront if something isn't feasible.
