I want to migrate our current application to hybrid application.
I try to use seller id and mwsAuthToken to get the LWA code in order to exchange for the LWA refresh_token where I found on the amazon migration guide. LINK
This is my request
https://sellingpartnerapi-fe.amazon.com/authorization/v1/authorizationCode?sellingPartnerId=[sellerId]&developerId=[developerId]&mwsAuthToken=[mwsAuthToken]
what I got from response is
{
“errors”: [
{
“message”: “Access to requested resource is denied.”,
“code”: “MissingAuthenticationToken”
}
]
}
Not sure what I really missing? Can anyone help about this?
