Overview
You are working on setting up an endpoint, e.g. you are trying to set up an endpoint to send critical tickets to. However. you may have issues when a trigger sends a request, some of the placeholder does not contain the corresponding data, instead you see the placeholder variable instead {{case.Subject}} or {{case.ID}} and you want to know how to format placeholders correctly.
Solution
Please make sure to use all lowercase characters when entering placeholder variables, as they are case sensitive.
For example, {{case.ID}} will not work, however, {{case.id}} will return the desired conversation ID.
