Chaining GraphQL requests based on answer-body or variable

Hello everyone,

I am currently trying to chain multiple GraphQL requests based on the answer-body of the first request. With my first request I request an authenticationToken. Then I want to check if I recived a token or not. Based on if I recived a token or not I want to either execute skript A or skript B.

My token looks like this if the request was succesful. If not instead of a token it will simply return “null”

“data”: {
“createAuthenticationToken”: {
“authenticationToken”: “XXXXXXXX-XXXX-XXXX-XXXXXXXXXX”

I am already successfully saving my token into a variable using this after response skript

How can I check my answer-body or my Current_Token variable and execute a skript based on the value?

Thank you
