Questions
Template FAQ
Does the template copy someone else's credentials?
No. FastHook creates a disconnected Draft. Connect your own PostHog accounts before activation.
Can I change the Steps and mappings?
Yes. The copied Workflow is an editable Draft. Review every Step, input, mapping, and route before you activate it.
What is copied into my workspace?
FastHook recreates the Trigger configuration, Action Steps, routes, and mappings with new IDs. Provider accounts, credentials, and secrets are never copied.
When does the Workflow start running?
Only after you connect the required accounts, finish the configuration, and explicitly activate the Draft.
