How to automatically get an authorization token in a Postman pre-request script
If you need to add an authorization token to each endpoint call in Postman, you can do it by using the following pre-request script:
pm.sendRequest({
url: "",
method: 'POST',
header: {
'Accept': 'application/json',
},
body: {
mode: 'raw',
raw: JSON.stringify()})
}
}, function (err, res) {
pm.environment.set("headerName", res.headers.get("headerName");
});
