Using Previous Node Data in Generic Credentials

Questions
1

Describe the problem/error/question

I’m creating a cookie using an endpoint and want to use that value in a Header Auth - Generic Credential Type.

I need to keep using this custom Generic Credential, which has a cookie generated dynamically from the previous step, for a complete execution and task as I invalidate this cookie at the end of the workflow.

How can I put a value from a previous step into a generic credential?

Please share your workflow

Nevermind, I realised I could call previous node using {{ $json.data }} as the expression in the credential’s Value field
