Hi all

I’m trying to create a Zap where an order is changed to a specific hold date based on a google sheet cell. 

The actions leading up to Shipstation are all working well, but we are getting an error 404 when we try it. Shipstation suggested updating the header, but I don’t think we have the power to do that in Zapier. Which leave me a bit stuck. 

I can’t (or don’t know how to) change the header to what they’ve requested. I’m also assuming the URL is ok with the API settings in it as that’s setup via the Zapier connection. 

These are the errors I am getting:

From what I can work out it is the text/plain that is causing the issue but I’m at a loss as to how to amend, or override, that within the Zap.

Here’s a copy of the 404 I get if I update the header:
