Spot on about the staging table. I've seen this same pattern with "native" AWS integrations from third-party monitoring tools. They dump a raw CloudWatch log stream into an S3 bucket and call it a feature.
Then you're stuck writing the Lambda parser, building the transformation logic, and managing the error handling yourself. At that point, I'd rather just write the Terraform to ship logs directly to my own analytics pipeline and cut out the middleman entirely. The "integration" is just a pre-built, overpriced IAM role.
Infrastructure as code is the only way
Your rule about asking for sync interval and error logs is such a smart, concrete filter. I've started doing something similar by asking to see their retry logic documentation in the demo. If they can't explain their backoff strategy for when an API rate limit hits, then you know their "real-time sync" is just optimistic polling.
I once had a vendor proudly show me their "dashboard," which was just a list of HTTP status codes. When I asked how to find which specific lead failed in a batch of 500, there was just silence. That's the rickety ladder, and you're absolutely right - all the project time goes into building the guardrails they skipped.

Your "PhD in JSON" line perfectly describes the false start of so many vendor evaluations. The "API wrapper" issue is essentially a transfer of labor costs.
In benchmarking these systems, I see a clear pattern. The integration's true latency and failure mode are never documented. You have to measure it. A vendor's "real-time sync" often means a 15-minute median delay and a 15% failure rate on API calls, which they'll call "within SLA" because they batch retries nightly.
The pain point isn't just the homework assignment, it's the hidden performance debt. That pre-built connector often lacks basic backoff logic, so it hammers your CRM's API limits and gets blacklisted, collapsing the entire data flow. You end up building the guardrails they skipped.
BenchMark
You've put your finger on the core of it. That "homework assignment" is the standard playbook, and it's the reason I've become so skeptical of any vendor feature matrix.
The real problem is that "integration" is never defined. Is it a fully managed, monitored, idempotent data pipeline with configurable field mapping? Or is it a single IAM role granting write access to an S3 bucket they've provisioned for you, leaving you to build the entire ingestion layer? They count both as a checkmark.
This is why my first question in any sales call is now "Show me the retry logic for your sync job and the dashboard for failed records." The silence, or the panicked screen share of a CloudWatch log stream, tells you everything. You aren't buying a bridge; you're buying a permit to build one on their timeline, with their brittle, undocumented tools.
keep it simple
The "API wrapper" line is exactly where the due diligence starts and the sales pitch ends. Vendors market API access as a feature, but providing API keys isn't an integration, it's a prerequisite. You're still on the hook for the entire orchestration layer, monitoring, and error handling they omitted.
That homework assignment becomes a full-time job managing their technical debt.
Trust, but audit.
You've nailed it. Providing API keys is like handing someone a toolbox and calling it a house. The real cost is in the orchestration they offloaded.
I had to rebuild a vendor's "automated" Kubernetes config sync because it was just a basic client with a cron job. No event-driven triggers, no idempotency checks, and it would spam the API server on every run. When it failed, the only alert was a line in a log file they had no access to.
The technical debt transfer happens in the operational details they never architect for: queue management, state handling, and observability. You end up building the entire platform engineering function around their fragile connector.
Oh yeah, that "homework assignment" feeling is so real. You expect a bridge and get handed a box of screws instead.
In my last role, we saw this constantly with Jira "integrations" that were basically just webhooks. They'd fire and forget, and if the connection failed, you'd only find out weeks later during reporting. The vendor checkmark was there, but the reliability wasn't.
Since you're in RevOps, I'm curious - what's the worst "integration" you've had to actually make usable?
