Zapier POST request returns unauthorized when Postman does not

Hi all - 

I am trying to use Code and Webhooks in Zapier to apply mod tags to a batch of questions once per day, depending on certain criteria. I used the method outlined by @mstone in this post to generate an API key. The key works great for GET requests, but when I try to POST, I see this:

 

 

The thing is, if I take the exact same token used for this request and use it in Postman, the POST request works fine. It seems to me that it isn’t a problem with the token, but maybe a problem with how I’ve set up the webhook. Does anyone have experience with this?

For reference, here is my request. I plan to incorporate it into a code block down the line once I ensure I have the correct inputs. I’ve tried Yes and No for “Wrap Request in Array”:

 

 

Also: I’m not a web developer! So if this is totally incorrect...that’s why ^^;

Any insight would be greatly appreciated! Thanks!

Ok I actually got it to work with Custom Request with these inputs:

 

 

So now I’m almost positive the problem in my original request was the structure of the data I was trying to send. What is the payload we send for a Zapier POST webhook?

@alexandra.culler thanks for sharing your steps and solution. What caught my eye is that in your first example “CS_Review” is a string, where is your second example m“CS_Review_Test_Zapier”] is a string within an array.

However ‘Unauthorized’ is a strange error to receive for that.
