Method

Backendless.UserService.getAuthorizationUrlLink(providerCode, fieldsMapping, scope, redirect, redirectAfterLoginUrl, callbackUrlDomain): Promise<string>;

where:

Argument	Description
providerCode	Name of the login provider as displayed in Backendless Console - see the specific provider screen at Users > Login Providers. String value.
fieldsMappings	Optional parameter. A mapping of user properties between OAuth provider and Backendless. If the map object is not null, it should contain a mapping between the provider specific property names and the column names in the Users table. Consider the following mappings: "my_email" >> "email" "my_name" >> "name" The key identifies the provider's property name and the value is the name of the mapped property (column name) in Backendless. In the example above, "my_email" and "my_name" are the properties returned by the OAuth2 provider and the corresponding values will be respectively stored in the "email" and "name" columns in Backendless. Must be an object.
scope	Optional parameter. A collection of security scopes the client application is requesting the permissions for. String value.
redirect	Optional parameter. Indicates if the server should return authorization URL or redirect to it. If the parameter is omitted, the server performs an HTTP redirect. Boolean value.
redirectAfterLoginUrl	Optional parameter. Represents a URL which is used to redirect a user to a specific page after the login operation. String value.
callbackUrlDomain	Optional Parameter. Allows customizing the callback URL which is used during the authorization process. By default, if the value for this parameter is not provided or set to null, the server will return the provider's authorization URL. However, when you provide a valid value for this parameter, the server will generate the URL with a callback that utilizes the specified domain. This feature allows you to tailor the callback URL according to your specific needs and enhance the authorization process for your application. String value.
