How to change user agent in header

I can’t properly see your Zap for some reason, but you should just be able to hard-code the user agent in the next step? You can add custom headers.

Hi @lalitswain - Try setting it as User-Agent instead of user-agent and it should work.

Thanks , it worked but the issue here is, I wanted to keep user-agent as blank or don't want to send this header in the post. 

If I am putting blank, it is taking default value. ie Zapier

is there anyway, can I send it as blank?

Yes, I was adding user-agent and it was not working. I changed to User-Agent and it works now.  I am trying to find a solution where we should not send any User-Agent or as blank. I am not able to figure out how to do it.

Thank you

Out of curiosity, why does the User-Agent need to be completely blank?

for a very specific case. 

“As of September, 2017, We recently discovered that if NO User agent is sent, NetSuite will work. Some server side applications are sending a User-Agent (it may not be obvious) and this causes a problem. We also discovered that NetSuite only lets some specific User-Agents in; I don’t have a valid list but it does mean you may need trial and error techniques to get it dialed in. “

@lalitswain - That’s probably not possible with the Webhooks by Zapier app.

You might want to use a code block instead. Here’s an example:

const response = await fetch("https://webhook.site/...", {
  method: "POST",
  headers: {
    "User-Agent": "",
  },
}).then(response => response.json());

return response;
