Need help With HTTP Post Pulling Information

Questions
1

Hey Community!

I am new to n8n and was playing around with setting up a voice AI agent with retell

I am using the http request and running POST in order to trigger a call with my ai agent

However, when I execute this step, it says “The resource you are requesting could not be found”

I have followed the retell AI documentation to the best of my ability and believe that I set it up properly

Here is what I have so far

URL: https://api.retellai.com/v2/create-phone-call

Header:

{
“headers”:{
“Authorization”: “Bearer [my API key here]”,
“Content-Type”:“application/json”
}
}

Please help!

there is nothing wrong with this code, perhaps you forget to set a permission in retell ai?

Hi All!

I was able to figure out the issue and get the call to trigger

Now I am having issues with the webhook lol

I input the webhook URL on the retell side but it never pulls the call summary.

Additionally, I would like for the call summary to be formatted as “Date of call - Quick call summary”, but I do not know how to set that up in N8N. I think the webhook would pull the call summary, feed it to my call summarization powered by OpenAI, and Open AI would have to summarize it based on my parameters?

I am not entirely sure so please help!

Here is the code for the whole tool

The webhook just says, “waiting for you to call test URL”

try to activate the workflow > do something with retell > see the executions tab, maybe it’ll help

have you set up a trigger for the web hook ? … this might help Webhook Overview - Retell AI

I’m having the same problems - how did you fix the http request node? I can’t figure out how to get the call to start
