Custom URL in GET request Action



I am trying to make a GET request with some data in the URL which I intend to populate dynamically from a variable.




The post part is what I am planning to set as a dynamic, so that it can be populated from a variable.



When I try to select the option "Add dynamic content" I do not know which "Expression" or "Dynamic expression" it is expecting.

Which ever I choose I get an error as "The expression is invalid."



Please can someone assist with this?


Thank you

Hi @Saikumar,


Could you please share a full screenshot of the configuration of your flow?

Could you provide more details about the Custom URL?

It would be helpful if you could post more details  and we would provide a proper workaround for you.


Best Regards,
