About ArcIntegrate
I built ArcIntegrate because I kept running into the same problem: the documentation you actually need to connect two enterprise systems rarely lives in one place.
My name is Robin Calvert. I've spent over 25 years working at the deep end of enterprise IT — card processing systems, global SaaS delivery, payment infrastructure for institutions handling Visa BASE I & II, VocaLink LIS5, and ISO 8583 environments. Through RDC IT Solutions Ltd, I've provided technical consulting and systems engineering to mission-critical financial platforms across EMEA and APAC.
That background gave me an appreciation for what rigorous technical documentation looks like — and how rare it is in the modern SaaS integration space.
Why ArcIntegrate Exists
iPaaS tools like Zapier and Make handle the transport layer. What they don't give you is the blueprint underneath: which OAuth scopes to actually request, how to validate webhook signatures correctly, what HTTP error codes you'll hit and why, and how to architect your retry logic so you don't lose data under load.
Every guide in this directory is written to answer those questions specifically. No marketing copy, no vague overviews — just the implementation detail you need to build something reliable.
Editorial Standards
Every integration guide published here is held to the same standard I apply to enterprise systems work:
Authentication
Exact OAuth 2.0 scopes, token lifecycle management, and webhook signature verification — not just "connect your account."
Resilience
Specific HTTP error codes, exponential backoff strategies, and idempotency handling for real-world failure conditions.
Payload Architecture
Concrete JSON structures and field-level documentation, not placeholder examples.
If a guide doesn't meet that bar, it doesn't get published.
