I'm react-native developer, I'm new to Magento, REST and OAuth. I want to use the Magento 2.0 OAuth REST API to login into my app I am getting this token as shown in the image, how can I use this token to do login authentication in react native application?
The token is NOT encoded user-information. There is no way to extract information from it on the client side. The token is a key in a DB table (oauth_token) where you can look up the customer_id tied to the token.
Or you make a second request (/customer/me) with that token to get all user info.
