How to test if a software integration actually works
Most software integrations only look seamless during a pre-built demo of the happy path. When real data flows between systems, hidden failures like unhandled API downtime, silent sync errors, and duplicate records break the workflow. This leaves teams manually fixing data instead of trusting automated processes.

“Six specialized tools might each be slightly better but maintaining six subscriptions, integrations and sources of truth is its own problem.”source ↗
“i'd ask to see the CRM and contact center integration live. Have a call come in identify the customer and pull up their history without their history without switching screens. Id also test duplicate and outdated records because thats usually where these integration fall apart..”source ↗
“spending time maintaining integrations can become ridiculous pretty quickly”source ↗
“If I can't see the thing actually pull real-time billing data without someone behind the curtain massaging a CSV, I'm already halfway out the door.”source ↗
“tbh id want to see what happens when the integration breaks mid-sync. every vendor can demo the happy path, the real test is how failures surface and whether the user even gets notified something went wrong”source ↗
“I’d insist on seeing the CRM connected to billing/ERP and support systems live—not just a pre-built demo. The real test is what happens when data fails to sync, duplicates appear, or an API goes down. That’s usually where “seamless integration” gets tested.”source ↗
“I’d probably ask to see the CRM + ERP integration live. Not just whether the data syncs, but what happens in a real flow from lead to quotation to order and invoice. I’d also check duplicate records, failed syncs and delays. That’s usually where you find out if the integration actually works as promised.”source ↗
“It seems that none of our integrations are currently working. Salesloft, hubspot, LI Navigator, etc have all stopped connecting and giving users a 422 code.”source ↗
