I am working on a messenger platform that uses a messenger webhook to receive messages, and the Graph API to send messages. I currently need to go into my app settings and choose to subscribe pages that I already own.
I am wondering how I can subscribe pages that I don't own to my webhook. Is this possible if I have the Page Access Token? I can build an OAuth2 flow to get the Page Access Token, but I don't see what to do with it once I have it.
Any help is appreciated.
This can be achieved by making a POST call to /{page-id}/subscribed_apps endpoint with your Page Access Token.
API reference docs are at https://developers.facebook.com/docs/graph-api/reference/page/subscribed_apps/

I am creating an application using which users will manage their Facebook messenger and post comments on a page. I have implemented the Facebook Login which asks the user for page_messaging permission. I have also configured the webhook and it is working fine.
Now, Facebook documentation states the following
Generate a Page access token to start using the platform APIs. You
will be able to generate an access token for a Page if:
You are one of the Page admins, and
The app has been granted the Page's permission to manage and access Page conversations in Messenger.
So, how can I make my webhook listen to the messages of the page that have granted me permission to manage and access the page? I have looked for hours trying to find this in the documentation. No Luck!
I went through the documentation for creating a chatbot for messenger platform.
All I find there, I need a server, which in the case used as a service for the Facebook platform.
The server also validates the webhook from facebook app.
Now I see, for a chatbot, I need a facebook app, webhook server and definitely a facebook page.
Then I find an application Flow XO, where I only put the page name and the bot is ready.
My question is, how they(flow.xo) can communicate facebook page without a Facebook app(appId, appSecret) and webHook.
My question is, how they can communicate facebook page without a Facebook app(appId, appSecret) and webHook.
They can’t.
They use their server and their app to communicate with the API, on behalf of the users that grant them access to their pages, by providing the necessary permissions when they log in to that app.
Facebook allows to create a Facebook App which integrates multiple chatbots. At Amio, we ask you for permission using Facebook OAuth. When you give us these permissions we send and receive message on your behalf. This allows you to create a chatbot using Amio API without need of creating a Facebook App.
Facebook Page is always needed as this is the entry point of users interacting with your bot. You can check Amio documentation for more detail.
I have an application that uses the Facebook messenger api to send and receive messages through a Facebook page. This works great. Now I need to be able to have a user in my application link their page so that messages sent to their page will send webhooks to our endpoint, and also give us the ability to send messages through that page using an auth_token.
Is there any way to do this via api, or will each user have to manually create a Facebook app, generate an auth_token for their page, and set the webhooks url to our endpoint? I've read about messenger account linking but I don't think it's quite what I need, as I'm not just looking to request additional profile information.
After looking a bit deeper, I found that in order to do this you must perform an OAuth flow to get an auth_token for the user, then use the graph api to get an auth_token for the desired user's page. Then with the page auth_token you can make a POST request to the subscribed_apps endpoint, which will then add the page to the app's webhook events.
I am creating an application where I need a user to be able to grant us access to their facebook page so that all incoming messages can flow through our application (as well as outgoing).
I have this all working correctly, but facebook will not approve my app due to the facebook permission pages_messaging and them "not receiving a response from my bot" (I have been denied three straight times). What am I doing wrong here? We are not using bots, do I even need the pages_messaging permission (I am using their webhook to get incoming page messages, and graph api to send outgoing)?
When submitting app, pages_messaging permission says:
Please provide the page that can be used to test this bot. Make sure the bot is properly connected and functional, otherwise your submission may be rejected.
Here is facebook's feedback from my submission (denied multiple times):
Thank you for your submission. We tested the messenger experience on your associated page and received no response from your messenger bot. Please resubmit with the new, improved version of your bot.
You got to create a bot to use the messaging API: https://developers.facebook.com/docs/messenger-platform/implementation
To just read/send messages:
https://developers.facebook.com/docs/graph-api/reference/v2.6/conversation/messages
You can use the /pageID/conversations endpoint to retrieve all conversations your page has had with FB profiles.
Next you can read/post to the /conversationID/messages endpoint to read/respond to a person.
And you can even subscribe to the conversations field for pages with webhooks.
You will need a page admin's page access token that has the read_page_mailboxes permission scope to set up the subscription, and to read/reply to messages.
I want to pull events from any facebook page(given a page id) using REST Api. I am writing a server application and there is not facebook user login that we are using.
You could do this with an eternal Page Access Token via the /{page_id}/events edge.
