Switching accounts

Vapi Team, I originally set up my Vapi account using my personal Gmail and created a phone number through that account. I now have a customer actively using this number, and since then I’ve established my company and a company email. Is there a way to transition my Vapi account from my personal Gmail to my company email while preserving my existing bot and phone number, so there’s no disruption for my customer?...

Regarding server URL

Hi Team, I have a use case where I need an end of call report for a call when the workflow is done. Since agent node does't support server url in it i set it up on org level. which led to spamming of events on my n8n workflow. Is there a way to limit it to send only the end of the call report or any way to set it up on workflow itself for the report?...

Flush syntax

I want to check if the LLM is actually generating responses with flush syntax, so I’m trying to extract the raw LLM response. I tested with voice.chunkPlan and voice.chunkPlan.formatPlan.enabled = false, but I didn’t see any <flush> tags in the assistant’s output. https://docs.vapi.ai/assistants/voice-formatting-plan#customizing-the-formatting-plan I’ve enabled the required configurations for flush syntax, but the results are inconsistent across calls. https://docs.vapi.ai/assistants/flush-syntax...

UI changes are totally inconvenient

The new UI makes it totally inconvenient for the agency owners with more than 5 organizations. There is no option to scroll down through organizations. Please revert it back.

Urgent: Unable to Verify Identity and Access Vapi Account

I am stuck on the KYC, a long-time user of your service for over a year, but I’m currently locked out of my account due to an issue with identity verification.

Can I port my Vapi free number to my Twilio account?

Structured Outputs 404 Error, Vapi Support then removed Structured Outputs

https://discord.com/channels/1211482211119796234/1405654269549609030 I reached out last week because my structured outputs tab was returning with a 404 error. Then some vapi support agent named King said he fixed the issue when all he did was REMOVE structured outputs from my dashboard. When I told the agent that wasn't my problem he stopped replying. WHAT IS GOING ON WITH THIS VERY SIMPLE ISSUE?...
