No. I am using HTTP Post method.

@Dark Kei 

so when you use POST method from ServiceNow how does the request body look like?

If my response helped please mark it correct and close the thread so that it benefits future readers.

As said, this was run on Test Runs in ServiceNow Platform.

Shorter texts are translating properly while longer texts do not. 
Please refer to the screenshots on my post.

Thank you

@Dark Kei 

not very sure then, will have to check at my side

hi @Dark Kei 

Try once by trigger the message via script (e.g., Script Include or background script) and see if it works with longer input.

Also check timeout settings.

I hope my answer helps you to resolve your issue, if yes please mark my answer helpful and correct.

thank you
