If possible, pin some example data into the first node before copying the workflow, so we can see the JSON you are receiving.

How have you configured your header credentials?

According to Tavily documentation it must be like this:

It looks like you didn’t set up the name correctly.

To day after watch few you tube , I try to create credential for custom HTTP node again ,i also modify my workflow , instead of input from Elevenlabs , as i already
venlabs more then 100 times , i replace with On form submission node , so i can fill in all inform and able to pin the data to track the error massage (I learn a lot from Travel agent workflow ) , See my workflow : -

So there are some new development below : -

Below are the step i did for set up credential : -

URLhttps://serpapi.com/search

Method POST

URLhttps://api.tavily.com/search

AuthenticationGenertic Credential Type

Genertic Auth TypeHeader Auth

Header AuthHeader Auth Account Final ( Just a name)

When Create the credential i enter below : -

Nane Authorization

Value Bearer API_Code

When i run i get Error code : -

Authorization failed - please check your credentials

Invalid API key. Your API key should be here: Sign In - SerpApi

Assume my API key is 1234567890qwertyuiop

I replace below script :-
URLhttps://serpapi.com/search

with below script :-
https://serpapi.com/](https://serpapi.com/search)manage-1234567890qwertyuiop

I get new error code : -
