Slow every send by (ms)

Affects messages the agent sends. Watch how it recovers or tells the agent.

Message tests From phone Burst — one message per line, sent quickly

A burst should reach the agent as one message. Replaying simulates the provider re-sending a webhook; it should be ignored.

Setting up

In Vexa, create a WhatsApp Simulator channel with a made-up phone number ID, pick an agent, activate it.
Type that same number as Business number on a phone here.
Say hello. To message a customer first, use the channel's "start conversation" call.
