Adding Social Login Provider

This guide discusses how to add a social login provider to frappe via pull request.

Add your provider in `SocialLoginKey.get_social_login_provider`

providers["Frappe"] = {
 "provider_name": "Frappe",
 "enable_social_login": 1,
 "custom_base_url": 1,
 "icon":"/assets/frappe/images/favicon.png",
 "redirect_url": "/api/method/frappe.www.login.login_via_frappe",
 "api_endpoint": "/api/method/frappe.integrations.oauth2.openid_profile",
 "api_endpoint_args":None,
 "authorize_url": "/api/method/frappe.integrations.oauth2.authorize",
 "access_token_url": "/api/method/frappe.integrations.oauth2.get_token",
 "auth_url_data": json.dumps({
 "response_type": "code",
 "scope": "openid"
 })
}

Add provider key in exact same type case in options of `social_login_provider` select field on `Social Login Key` DocType. e.g. `Frappe`

Once the user adds a social login provider and enables it the Authorization Code is sent back by the provider api server on to the redirect_url mentioned on the same server. You will have to add a whitelisted method allowing guest access in frappe.integrations.oauth2_logins. e.g. login_via_office365

There many implementations of OAuth 2.0 + OpenID Connect. Here we'll discuss two ways of accessing openid information.

User Creation via OpenID Profile Endpoint

example:

@frappe.whitelist(allow_guest=True)
def login_via_frappe(code, state):
 login_via_oauth2("frappe", code, state, decoder=json.loads)

User Creation via id_token
