I'm trying with the Facebook iOS SDK to subscribe to a page so that I can utilize a web hook and receive updates when a person comments on the page. However, It does not work.
I request these login permissions:
FBSDKLoginManager *login = [[FBSDKLoginManager alloc] init];
[login logInWithPublishPermissions:@[@"manage_pages", @"publish_pages"]
And grant permission.
But then, when I make this graph API call
FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc] initWithGraphPath:[NSString stringWithFormat:@"/%@/subscribed_apps", page_id] parameters:nil tokenString:token version:nil HTTPMethod:@"POST"];
I get this error:
permission pages_messaging is required to register webhook for messages or deliveries
So, when I attempt to request that permission at login it gives me yet another error:
Request:
[login logInWithReadPermissions:@[@"pages_messaging"] fromViewController:self handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
}];
Error Screen:
I've looked all over Facebook's Doc's and can't find an explanation as to what I'm doing incorrectly. Is there some other way to request this permission?
The page I am trying to subscribe to is owned by the user and it's a business page - not a personal page.
Permission pages_messaging
was introduced with API v2.6.
Your app seems to be using an older API version - and using that, you can not ask for that permission.
So you have to upgrade your app to use API version 2.6 first, before you can ask for it.
