I am trying to build a scheduled lambda function that automatically uploads the catalog every day by using the Alexa Skill Management API (https://api.amazonalexa.com), but according to the documentation (https://developer.amazon.com/docs/smapi/catalog-content-upload.html) I can only use the API with the Authorization header whose value should be the access token retrieved from Login with Amazon.
Will there any way to use the rest API without having to manually log in with Amazon every time? Will there be any solution that allows this by using the AWS access key and secret? Or is there any other recommended way to achieve the goal?
