Now, I have created a connected app, selected some oauth scopes, set a callbackUrl(https://login.salesforce.com/services/oauth2/success).
Then add it to the package, bulid a release package. When install the package in the Professional/Group Edition, I invoke the rest API, obviously, it failed , then the authorize starts work
(The url is https :// ap2.salesforce.com /services /oauth2 /authorize?response_type = code&scope = full + refresh_token & client_id = {0}&redirect_uri = https :// login.salesforce.com /services/oauth2/success).
But it looks not work, and dispaly a message
'Remote Access Application Authorization'.
click allow authorize, deny not.
