Hi Team,

i need to set an rest API which needs authentication. can anyone help me with sample code on how to give authentication of the API in yml file.
i refer the configuration document but did not get any idea on authentication.

Req Body:

{
"servicerequest": {
"priceandstockrequest": {
"showwarehouseavailability": "True",
"extravailabilityflag": "Y",
"item": [
{
"globalskuid": "A300-9702ZT",
"quantity": 0,
"referenceid": "f8e2b66e-2df2-46db-9626-65be4e559ad7"
}
],
"includeallsystems": false,
