Here’s what normally has to happen for a “Stop on Action ✓” Custom Action to pause the flow and wait for your website to respond with the success event:
1. In the Voiceflow project
• Custom Action block has “Stop on action” enabled.
• You added an outgoing path called success (exact-case match). 2. From the client (your extension / website)
• The first
Otherwise the Dialog-Manager keeps executing and will hit the End step, even though “Stop on action” is checked in Creator. • The Dialog-Manager response you get back will end with a trace: As soon as you receive that trace you should send a second
• Path name mismatch (e.g. “Success” in the block but you send
• No outgoing path on index 0, so DM falls through to the default path that ends the chat. Quick checklist ---------------

✅ In every request that should pause at that block, pass

DM will then follow the success path and continue the conversation.
Most “flow suddenly ends” issues come from one of these:
• stopTypes not supplied in the initial interact call – DM never pauses.• Path name mismatch (e.g. “Success” in the block but you send
"success" or vice-versa; path names are case-sensitive).• No outgoing path on index 0, so DM falls through to the default path that ends the chat. Quick checklist ---------------
✅ Add the success path to the Custom Action block.
✅ Use exactly the same string in the second interact request’s
action.type.✅ In every request that should pause at that block, pass
config.stopTypes: ["<Custom Action Name>"].
