Hi @ak-0283 Make sure you add correct scripts in your add a book request
add this in your scripts:

// save the "id" value from the response to a variable named "id"
const id = pm.response.json().id
// save the id as a collection variable named "id"
pm.collectionVariables.set("id", id)

secondly add authorization:
