Hi @VIktor1515 

Have you tried to create a custom action for Shopify with the help of AI?

 

I tried the whole thing in Custom Actions. Still get the Error Code 400. 
I also inserted the JSON code in the JSON validator and it shows me errors.

@Troy Tessalone 

Even with API Request (Shopify) does not try any change Error Code 400 remains. 
Also tried "Order ID", "Order Line Items ID", "Order Line Items Variant ID", Order Linbe Items Product ID".

@VIktor1515

This is not valid Body JSON, and looks like JavaScript.

 

From the Shopify API endpoint docs:

 

Thanks @Troy Tessalone, nevertheless I get an error code 404 in all 3 versions "Custom Request by Webhook", "API Request in Shopify" and in "Custom Actions in Shopify"
Below I have attached the API Response from the Zap Custom Actions in Shopify.

@VIktor1515 

Have you tried asking ChatGPT for help checking/configuring the JSON and other elements of your HTTP request?

Got it. Thank you again for the comments @Troy Tessalone :). It was the wrong ID...

@VIktor1515  can you share the final code you used and also which ID you pulled?
