Hi everyone,
I’m working through a Klaviyo issue and wanted to see how other teams handle it.
For example, a flow relies on checkout_url or expects cart_total to be a number. Later, an integration starts sending checkout_URL, renames the field, or sends cart_total as a string. The flow is still there, but the template or filter may no longer behave as expected.
I built a small read-only check for this and tested it against a live flow. Now I’m trying to understand whether agencies actually see this across client accounts, or whether it’s mostly an edge case.
How do you catch changes like this today—manual QA, periodic audits, support tickets, or something else?
And if you do run into it, would an alert showing the exact property and where the flow uses it be useful?
I’d really appreciate any real-world examples.
