Trying to trigger multiple outbound calls with csv upload in Vapi UI. Getting the attached error message. Header 1 in csv is "customer" and header 2 is "number" https://cdn.discordapp.com/attachments/1371747549144154144/1371747550750576650/Screenshot_2025-05-13_at_5.13.33_pm.png?ex=682442f5&is=6822f175&hm=58d6ef2602df65c5a14accf66eb80ea7126cad71dc26843199434c0bcd68fd92&

It looks like the error you're seeing is related to the "assistantOverrides" section in your CSV upload. The message "property customer should not exist" suggests that the "customer" property is being included where it shouldn't be. You might want to review your CSV file and remove the "customer" property from the "assistantOverrides" object for each customer entry. This should help resolve the issue with triggering outbound calls.

Hey! To help track down this issue, could you share: - The call ID - When exactly this happened (the timestamp) - What response you expected to get This would really help us figure out what went wrong!

@Shubham Bajaj what you're asking here is not relevant to this issue as the calls were not triggered at all. I am getting the above error on the Phone Numbers page when trying to trigger outbound calls via a CSV upload.

Please use this csv template file for triggering outbound calls https://cdn.discordapp.com/attachments/1371747549144154144/1373097064766111786/outbound4.csv?ex=68292bcb&is=6827da4b&hm=0fcdc86216e71467e5e05dc679a9b53d1c2c349bbf408d394a69bb0a3d0a351d&

Hi Kyle, we've been able to trigger an outbound call with this csv structure - tested with 3 numbers. Unfortunately, only one call gets through though. The other two go to Voicemail, even though the lines a clear. Any idea on why this is happening? Separately, how do we get the AI to input the first name, and other details from the csv as spoken messages? e.g. Hi {{name}} isn't working. Call IDs: Successful call that got through - 748cf312-c130-417c-be5f-7bc5ada8cc63 Did not get through - c3c5d0e2-1722-4af3-b925-d0327403e4a8 Did not get through - a92a9b22-b185-4298-9f85-b5316970b9b3

use {{customer.name}} and that should fix it. also, I am not sure I am understanding your question correctly. could you please elaborate or rephrase the question? or possibly answer these questions: - what result do you want - what was the actual result

@kyle this code {{customer.name}} solved the personalisation. Regarding the bulk/batch outbound calls... What we need to happen: - When we upload a CSV file with multiple numbers, we need all calls to be made. What currently happens (the issue): - Only one of the calls is successfully being made. - The rest of the calls are not actually going through. The Ended Reason is Voicemail, when the lines are available to take a call.

Hey Liv, you can go through this documentation and it will solve your issue related to CSV issue.

@Sahil thanks for sharing. Although the issue is now with the calls being made (see comment above).

I understand you're looking for an automation flow to call again when the line is free. Unfortunately, we don't have that feature at the moment. In the meantime, you can check out this video for more information: .

Thanks @Sahil trying to access the outbound calls template and getting a "Page Not Found" - https://docs.vapi.ai/assets/batch-sample.csv How would we set up the CSV to also include the dynamic variables for email, address, date of birth and member card number?

@kyle can you fix it?

@kyle Hey Kyle, any ideas on this one? Could this be something to do with order of columns or heading names in the CSV?

We are working on fixing that documentation page which should be completed by Friday. For the CSV error, we are currently working on a fix and should have an update to you later today.

any updates on this?

Page is still being worked on but the CSV has been fixed. I will attach it here https://cdn.discordapp.com/attachments/1371747549144154144/1379661608523010069/batch-sample2.csv?ex=68410d80&is=683fbc00&hm=ae0f6426cc6b5d53e7ff481e7386f3048414ae4aedb51ec02b41e41830fbd4c1&

Hi Kyle, do you have a version with the dynamic variables I listed above (email, address, date of birth and member card number)? Have tried different ways e.g. underscores, dots etc. but nothing is working. I'm getting the attached errors. The calls are only successfully triggered when the CSV only has number and name columns, but we need the rest to work. https://cdn.discordapp.com/attachments/1371747549144154144/1387265218467332096/Screenshot_2025-06-25_at_12.55.33_pm.png?ex=685cb6ea&is=685b656a&hm=09cee0f5021fe981bf395500b9504ca4b197346a14c16ced1c487b7dda93bbca& https://cdn.discordapp.com/attachments/1371747549144154144/1387265218891087882/Screenshot_2025-06-25_at_12.55.05_pm.png?ex=685cb6ea&is=685b656a&hm=d126ed294fc6dddf6abcff809200a47c0eb1aa6e1d7044e8785510b44c5e644c& https://cdn.discordapp.com/attachments/1371747549144154144/1387265219318779995/Screenshot_2025-06-25_at_12.54.48_pm.png?ex=685cb6ea&is=685b656a&hm=9b95a6ce05ec82656489c2404bc9f5b4fba1da3baa928f3b3740754c823f73e8& https://cdn.discordapp.com/attachments/1371747549144154144/1387265219713306684/Screenshot_2025-06-25_at_12.49.11_pm.png?ex=685cb6ea&is=685b656a&hm=0595f2229df0817cfff7298c1282f5b66687a5a24c9a8f6f9d7b9b14ca5d4174&

When creating an assistant via API endpoint, define the assistantOverride values you want to add ( {{customer.email}}, {{customer.DOB}}, etc. ) then upload the CSV. If you need assistance with the API request, let me know.

@kyle have been testing out the new Campaigns feature today and this is working! Great feature. Will mark this as Solved. Thank you for your help.

Glad the issue was resolved. Please reach out to us if you have any other questions regarding this issue
