I'm trying to decipher if by "failed to connect" they mean that there was some auth issue / issue when trying to use one of the endpoints on that server or if it just failed to even connect at all altogether. my server is running on port 3005 and has an endpoint for shttp at 3005/mcp, but I tried both and still got the error. No logs in my ec2 where it's hosted either which make me wonder if it even connected at all. Anybody encounter this and know the correct setup or fix?

Do I just need to copy the workflow id and use in env variables or anything else

I created a squad in the dashboard and connected three assistants, but inside the squad they don’t behave as expected. They say the wrong things, don’t execute the tool functions, often misunderstand what I say, and sometimes the main assistant doesn’t transfer the call to the other assistant. I double-checked everything in the squad setup assistants, configurations, models, voice, and even the pre-transfer message everything is filled in correctly.

hi someone please I need help for inbound calls with n8n it wont recognize any assistant override commands i give it only on outbound calls has anyone had this issue?

Problem: Private API Key secret not shown at creation; only Key ID appears. This blocks API auth (Authorization: Bearer ) and returns 401 Unauthorized. Repro steps: Dashboard → API Keys → Add Key → Private Allowed Origins: empty | Allowed Assistants: empty | Transient Assistant: OFF Click Create Private Token → redirected to keys list → no modal / no secret shown List shows: top row with asterisks (hidden), bottom row with Key ID (UUID). Eye/copy on the top row doesn’t reveal/copy the secret; copying the lower row gives only the Key ID. What I tried: Delete & recreate multiple times Browsers: Chrome / Edge; Incognito; cleared cache; disabled extensions; hard reload Plan: Starter Expected: One-time reveal of the private key secret (long token) right after creation. Actual: Only Key ID visible; cannot obtain the secret. Request: Confirm if this is a dashboard/UI issue. Help me obtain the secret (or generate a private key for my workspace) so I can use: Authorization: Bearer GET https://api.vapi.ai/assistant?limit=1 Any workaround to retrieve the secret on creation.

When I call in to assistants, they are not hearing or at last not responding to caller. The aaistant just says the opeing mesaeg and then neve responds after that. I have ttried on mutiple phones and still the same issue.

Using ghl_contact_get and the incoming call arrives as 083407**** instead of +2783407***** so GHL contact isn't found... I can't seem to get E.164 out of VitalPBX in the incoming call string?

ghl_contact_get with incoming calls checks for email first, fails so assistant says - Just a sec - then checks phone and sys Hi Paul - really you're a voice company so default phone before email please!

The verification doesn't complete, doesn't say there was a problem of anykind. Doesn't ask me to resubmit. Told Vapi support about the issue but heard nothing other than their automated email 60 hrs + ago!

I’ve been working on a customer support workflow in VAPI that includes emergency handling, appointment booking, rescheduling, FAQs, and follow-up flows. I’m running into some issues specifically with the appointment booking path: The availability check often stalls or fails to properly confirm dates that are already booked, seemingly bypassing the tool altogether. The event creation step doesn’t register at all, no matter what I try. I explicitly desrcibed the tools functionality (when to be launched and basic tasks) , connected my google calendar to vapi aswell as mapped startdatetime and enddatetime within the workflow 👉 What’s the correct way to structure the appointment booking path (availability + event creation) so it doesn’t stall or fail? 👉 Could there be something wrong with how I’m using the Google Calendar tool that’s preventing events from being created? workflow ID: 3cdb6458-a1f3-4365-8566-eb997628396d

Hi, After importing a JSON configuration file containing a custom transcriber setup, the entire VAPI dashboard UI became unusable. I now get a persistent React error #130 when trying to access any workflow or even create a new one. This affects all workflows on the account, not just the one I imported. I've tried: Using my colleagues account, imported same file, sma thing happened Hard refreshing the browser Clearing cache and cookies Using incognito mode Disabling browser extensions Trying different browsers (Chrome, Firefox) Testing from a completely different device/network None of these steps resolved the issue. This is a critical blocker preventing any further work on the platform. Here are the ss of the error and the ss of interface not working and json file that was uploaded… https://cdn.discordapp.com/attachments/1408781503277699124/1408781503667900498/43097C74-A1F0-41A1-8D25-B03352440B41.jpg?ex=68aafd84&is=68a9ac04&hm=cb930e496954d112a0e48754ddca0faa8284aa541f8efdaa526f01c77f625ace& https://cdn.discordapp.com/attachments/1408781503277699124/1408781504015765544/IMG_3337.png?ex=68aafd84&is=68a9ac04&hm=9fe3a90c7d8b7b75b97146070606236f85ab4b0a3cb21c8e9d231e061f105464&

Hello VAPI Support, I’m experiencing an issue where call logs are visible via the API but do not appear in the dashboard. Here are the details: - Call ID: 6a96b8e7-8fb3-44bd-aabc-5259f0f080be - Organization ID: 6c7396ee-497c-4075-8348-946295ca878a Symptoms observed in the browser: 1. Network request to Cloudflare PAT endpoint fails with 401 Unauthorized: GET https://challenges.cloudflare.com/cdn-cgi/challenge-platform/.../pat/... → 401 Unauthorized 2. Sentry logging is rate-limited: POST https://o4506313494298624.ingest.us.sentry.io/... → 429 Too Many Requests 3. Console warnings indicate failed fingerprint integrations: Dodgeball SDK: No URL provided for integration: DODGEBALL_FINGERPRINT_SERVICE_V2 What I’ve confirmed: - The API calls to /call/list and /call/{id}/logs succeed and return the expected call data. - This indicates the backend and recording settings are functioning correctly. - The issue appears to be frontend-related, likely related to the Cloudflare PAT mechanism or dashboard JS failing to load required resources. Request: Please advise on: 1. How to ensure the dashboard frontend properly retrieves the private access token for my account. 2. Any additional steps needed to fix the call log rendering issue for this Call ID. Thank you for your assistance. Best regards, Felix

I’m seeking individuals who would be willing to rent me their Upwork account. Here’s how it works: - Income Sharing: I will pay you 25% of the income I generate through your account. - Growth Potential: While the first month’s income might be less than $1,000, as we build a reputation and grow the account, the earnings can increase significantly. If you don’t have an Upwork account, no worries! You can create one now, and I’ll assist you through the process. If you want, agree or not disagree, It's your mind.

Is it possible to turn of voice recordings in Workflows?

Has anyone here had any problems using query_tool? I have already configured everything correctly as stated in the documentation and on YouTube. But the answer is always the same, the wizard calls the tool, it says {"KnowledgeBaseNames": ["the name of my base"] And the answer is only success, Since it should return the document information.

I signed up Vapi.Ai last night as part the AI Army program. After signing up, I cannot get to the dashboard. I have Microsoft Edge and Chrome and Opera on a Microsoft Windows 11 laptop. I have tried accessing VAPI from an Android tablet and I have tried accessing my account from my Android phone. I do not know what is going on but on everything except the phone I cannot get to the dashboard. It gets stuck on the "Where did you hear about US" screen On my phone I was able to get to the dashboard but then when I went to go create a VAPI phone number the screen just freezes up and becomes unusable. I kind of think that your software might be way too buggy and that I should request a return from AI Army because if it's this buggy from the start it makes me rethink this endeavor . I don't know what to do so if you have any tips let me know.

I would like a specific tool to be used by many assistants, but to do this I need to pass a specific parameter (different for each assistant). However, I don’t see any function available that would allow me to assign a variable to an assistant and have it remain always available. Does this functionality not exist for a specific reason? Would you recommend a different approach?

Hi Vapi Team, Thanks for your message. Here are some of the Call IDs where we encountered unexpected behavior: eaea366d-af4f-44ac-94e4-4dabd8caa786 b8deeb98-6194-4303-bbc8-ddf4313089f9 d3f9bc79-da5e-4a97-b117-8d2936ca20bd c8b7e144-4953-4862-962c-1a0bb0cf4601 64181ff0-1606-4328-ba2b-b597ce568f7c You already have our email (masdouk@techma.ca), and based on that, we believe you also have backend Access Given that, we expect the issue can and should be debugged on your end. Please investigate using these call IDs and let us know what you find. Looking forward to your update. Best regards, Jass

Webchat MCP calls don't actually contact the server: When asking the bot a question that trigger a tool call the bot stops for more then 10 seconds, then if prompted again act like everything is fine. Checking chat logs I see that the tool call get executed but from my server logs no connection went through. The webcall from the same identical Assistant with the same MCP settings work just fine. The following are some ids for troubleshooting: Organization ID: 8193fb1e-c62c-42fa-bfe5-6590e5a705f6 Webcall ID (successful MCP): a788e6d0-9bb9-4875-a2ca-e7011a3f45a1 Webchat IDs (not working MCP): 29b88a43-322d-401d-bc4b-a13fe0948803 ab223e29-43bf-4ddf-a3ad-c7747dc0a0f9

If we add any kind of message to the query tool, the assistant stays silent after a successful call. It also ignores the start message. Trying to add this kind of messages trough prompting is not as reliable, so this is necesary.

We have identified a recurring issue where calls are prematurely terminated by the assistant. Instead of proceeding with the expected conversation prompt, the assistant abruptly says the "good bye" phrase, and ends the call. This behavior has been consistently observed across multiple calls and appears to originate on VAPI's side. To support your investigation, I have: Reviewed the VAPI dashboard to identify that the calls with this error have unusually short duration (around 2-3 seconds). They are specifically focused on calls marked with "Assistant Ended Calls" as the termination reason. Here are some of the ID calls with this issue: 770df206-5508-4a5b-9181-02331793e100 c3d3d5db-0710-457c-b40d-32b66d14c9f6 15024303-2f30-4b62-9be7-79044b3a3384 d7b9225a-1553-4f3e-9da4-32b0dfd76fbf 55b01e9a-b4d5-45a5-87cd-df8ac826fadd f9d6f53f-54f5-4932-900f-25f8027aa0fd 87ea15c7-755d-4c7c-bdb9-56887ae2f42d f90d8d66-bee5-4824-b5c2-e4fafa5b52ae fe69584d-1cb2-4fb2-9f86-25429b3878fa 8b047445-2f2f-4b60-b517-7e1a0b1b0ce0
