## Details

### GoaOAuth2Based

    typedef struct _GoaOAuth2Based GoaOAuth2Based;

Abstract interface type for the D-Bus interface org.gnome.OnlineAccounts.OAuth2Based.

### struct GoaOAuth2BasedIface

    struct GoaOAuth2BasedIface {
      GTypeInterface parent_iface;

      gboolean (*handle_get_access_token) (
        GoaOAuth2Based *object,
        GDBusMethodInvocation *invocation);

      const gchar * (*get_client_id) (GoaOAuth2Based *object);

      const gchar * (*get_client_secret) (GoaOAuth2Based *object);
    };

Virtual table for the D-Bus interface org.gnome.OnlineAccounts.OAuth2Based.

GTypeInterface `parent_iface`; | The parent interface.
`handle_get_access_token` () | Handler for the "handle-get-access-token" signal.
`get_client_id` () | Getter for the "client-id" property.
`get_client_secret` () | Getter for the "client-secret" property.

### goa_oauth2_based_interface_info ()

    GDBusInterfaceInfo * goa_oauth2_based_interface_info    (void);

Gets a machine-readable description of the org.gnome.OnlineAccounts.OAuth2Based D-Bus interface.

Returns : | A GDBusInterfaceInfo. Do not free. [transfer none]

### goa_oauth2_based_override_properties ()

    guint               goa_oauth2_based_override_properties
                                                            (GObjectClass *klass,
                                                             guint property_id_begin);

Overrides all GObject properties in the GoaOAuth2Based interface for a concrete class. The properties are overridden in the order they are defined.

`klass` : | The class structure for a GObject-derived class.
`property_id_begin` : | The property id to assign to the first overridden property.
Returns : | The last property id.

### goa_oauth2_based_get_client_id ()

    const gchar *       goa_oauth2_based_get_client_id      (GoaOAuth2Based *object);

Gets the value of the "ClientId" D-Bus property.

Since this D-Bus property is readable, it is meaningful to use this function on both the client- and service-side.

### Warning

The returned value is only valid until the property changes so on the client-side it is only safe to use this function on the thread where `object` was constructed. Use `goa_oauth2_based_dup_client_id()` if on another thread.

`object` : | A GoaOAuth2Based.
Returns : | The property value or `NULL` if the property is not set. Do not free the returned value, it belongs to `object`. [transfer none]

Sets the "ClientId" D-Bus property to `value`.

Since this D-Bus property is not writable, it is only meaningful to use this function on the service-side.

`object` : | A GoaOAuth2Based.
`value` : | The value to set.

### goa_oauth2_based_dup_client_id ()

    gchar *             goa_oauth2_based_dup_client_id      (GoaOAuth2Based *object);

Gets a copy of the "ClientId" D-Bus property.

Since this D-Bus property is readable, it is meaningful to use this function on both the client- and service-side.

`object` : | A GoaOAuth2Based.
Returns : | The property value or `NULL` if the property is not set. The returned value should be freed with `g_free()`. [transfer full]

### goa_oauth2_based_get_client_secret ()

    const gchar *       goa_oauth2_based_get_client_secret  (GoaOAuth2Based *object);

Gets the value of the "ClientSecret" D-Bus property.

Since this D-Bus property is readable, it is meaningful to use this function on both the client- and service-side.

### Warning

The returned value is only valid until the property changes so on the client-side it is only safe to use this function on the thread where `object` was constructed. Use `goa_oauth2_based_dup_client_secret()` if on another thread.

`object` : | A GoaOAuth2Based.
Returns : | The property value or `NULL` if the property is not set. Do not free the returned value, it belongs to `object`. [transfer none]

### goa_oauth2_based_set_client_secret ()

    void                goa_oauth2_based_set_client_secret  (GoaOAuth2Based *object,
                                                             const gchar *value);

Sets the "ClientSecret" D-Bus property to `value`.

Since this D-Bus property is not writable, it is only meaningful to use this function on the service-side.

`object` : | A GoaOAuth2Based.
`value` : | The value to set.

### goa_oauth2_based_dup_client_secret ()

    gchar *             goa_oauth2_based_dup_client_secret  (GoaOAuth2Based *object);

Gets a copy of the "ClientSecret" D-Bus property.

Since this D-Bus property is readable, it is meaningful to use this function on both the client- and service-side.

`object` : | A GoaOAuth2Based.
Returns : | The property value or `NULL` if the property is not set. The returned value should be freed with `g_free()`. [transfer full]

### goa_oauth2_based_call_get_access_token ()

    void                goa_oauth2_based_call_get_access_token
                                                            (GoaOAuth2Based *proxy,

Asynchronously invokes the `GetAccessToken()` D-Bus method on `proxy`. When the operation is finished, `callback` will be invoked in the thread-default main loop of the thread you are calling this method from. You can then call `goa_oauth2_based_call_get_access_token_finish()` to get the result of the operation.

See `goa_oauth2_based_call_get_access_token_sync()` for the synchronous, blocking version of this method.

`proxy` : | A GoaOAuth2BasedProxy.
`cancellable` : | A GCancellable or `NULL`. [allow-none]
`callback` : | A GAsyncReadyCallback to call when the request is satisfied or `NULL`.
`user_data` : | User data to pass to `callback`.

Finishes an operation started with `goa_oauth2_based_call_get_access_token()`.

`proxy` : | A GoaOAuth2BasedProxy.
`out_access_token` : | Return location for return parameter or `NULL` to ignore. [out]
`out_expires_in` : | Return location for return parameter or `NULL` to ignore. [out]

Helper function used in service implementations to finish handling invocations of the `GetAccessToken()` D-Bus method. If you instead want to finish handling an invocation by returning an error, use `g_dbus_method_invocation_return_error()` or similar.

This method will free `invocation`, you cannot use it afterwards.

## Property Details

### The `"client-id"` property

      "client-id"                gchar*                : Read / Write

Represents the D-Bus property "ClientId".

Since the D-Bus property for this GObject property is readable but not writable, it is meaningful to read from it on both the client- and service-side. It is only meaningful, however, to write to it on the service-side.

Default value: NULL

### The `"client-secret"` property

      "client-secret"            gchar*                : Read / Write

Represents the D-Bus property "ClientSecret".

Since the D-Bus property for this GObject property is readable but not writable, it is meaningful to read from it on both the client- and service-side. It is only meaningful, however, to write to it on the service-side.

Default value: NULL

## Signal Details

### The `"handle-get-access-token"` signal

    gboolean            user_function                      (GoaOAuth2Based        *object,
                                                            GDBusMethodInvocation *invocation,

Signal emitted when a remote caller is invoking the `GetAccessToken()` D-Bus method.

If a signal handler returns `TRUE`, it means the signal handler will handle the invocation (e.g. take a reference to `invocation` and eventually call `goa_oauth2_based_complete_get_access_token()` or e.g. `g_dbus_method_invocation_return_error()` on it) and no order signal handlers will run. If no signal handler handles the invocation, the `G_DBUS_ERROR_UNKNOWN_METHOD` error is returned.

`object` : | A GoaOAuth2Based.
`invocation` : | A GDBusMethodInvocation.
`user_data` : | user data set when the signal handler was connected.
Returns : | `TRUE` if the invocation was handled, `FALSE` to let other signal handlers run.
