FAQs

Quick answers to common integration questions.

Where export is possible, yes. Otherwise we replicate logic and content (flows, audiences, templates) 1:1.
Every project ships with a versioned configuration, API keys inventory, data mappings, and rollback notes.
We wire your CMP to tag firing rules, pass consent signals, and limit PII where tools allow.
