Hi everyone,

We’ve been using Zoom ZVA’s built-in transfer_to_live_agent tool to route customers into our ZCC flow. Overall it works well (around 90–95% success rate), but we’re running into an unavoidable issue where the transfer fails because the required variables aren’t being set by the agent properly before execution.

These variables are critical on our end since they determine which queue the customer gets routed to.

Has anyone else experienced something similar with variable handling during transfer? If so, how did you resolve it or work around it?

Any insights would be amazing!

Thanks,

Yup, I’ve seen it @Arpit V. And your 90-95% success rate makes me think the bot's deciding on its own when to fire the transfer, and sometimes it jumps the gun. Easiest/most consistent fix - Give it more direction. Put the transfer inside a small flow that checks the variables first, so the bot can't call it prematurely.

In the flow editor, replace the direct tool call with:
Variable Set — assign your routing variables.
Condition — check all required variables are non-null. If not, loop back to ask the customer.
Transfer to Live Agent — it only runs after the check passes.
