I'm trying to get a refresh token for Google through Oauth.io but I'm having trouble finding the endpoint to send the code to. I'm using C# so I can't use the server-side SDK. I've also looked at Getting refresh tokens from Google with OAuth.io but that answer doesn't help me get the actual refresh token. I've looked at their server-side flow documentation which tells me I can get my refresh token at /auth/access_token but when looking at the web API documentation I don't see that endpoint listed.
I've also looked at their example here and I don't see the endpoint they use listed on the API documentation either. It also doesn't say which key/secret to use with that request - is it the one listed for my OAuth.io app, or is it the one for my provider (in this case Google)?
Any help going forward would be greatly appreciated.
I've just updated the documentation on docs.oauth.io, it was effectively /auth/access_token.
Take a look at the node.js SDK implementation: https://github.com/oauth-io/sdk-node/blob/master/coffee/lib/authentication.coffee#L99
The request is a
POSTonhttps://oauth.io/auth/access_tokenand require 3 parameters:code: the code to be exchange against the access token / refresh tokenkey: the OAuth.io public keysecret: the OAuth.io secret key
