In the page setup on Meta For Developers it says that the account (test number) does not exist in the Cloud API. I was previously able to run tests normally with the provided test number (receiving messages on my personal phone), but since yesterday afternoon, I've been getting some message like:

"Failed to send message. The account does not exist in the Cloud API. Use the /register API to create an account first."

Making the request in Postman, I have the following response:

"error": {     "message": "The account is not registered",     "type": "OAuthException",     "code": 133010,     "error_subcode": 2593006,     "is_transient": false,     "error_user_title": "The account does not exist",     "error_user_msg": "The account does not exist in the Cloud API. Use /register API to create an account first.",     "fbtrace_id": "A6fN7xoCSrj2t1dW_Qvv5d0" } 

In my Flutter project (VSCode), the Debug Console also shows:

"flutter: {error: {message: The account is not registered, type: OAuthException, code: 133010, error_subcode: 2593006, is_transient: false,..."

Despite my best efforts, I've reached a dead end... help me please.

I've tried everything I can think of: checking all the API settings, sending messages to different numbers, reviewing the documentation, and searching the internet for similar issues. But nothing seems to work. I just need to get the tests running again.

I am integrating WhatsApp Cloud API into my chat application. During the process, I've already integrated it, but I want to restrict people to add WhatsApp Business phone number into Group Chats.

It is possible to update the settings through WhatsApp itself, in order to use WhatsApp Cloud API, that number must not be registered as WhatsApp account. Therefore I can't edit through WhatsApp.

I know, I have to edit this via Business Portfolio, but I couldn't find it. I did multiple research, didn't find anything useful.

If somebody know, how to achieve this, please let me know. Thanks in advance.

i have created a facebook app. the purpose is to get the details when someone make a comment on a post or interact with the page. I have set up the webhook url, got the challenge and the process is complete. After that in order to get the feeds i have subscribed the feeds under page and some other page related(i have set up the permissions which are requested in facebook documents and even tried all the permission available there) permissions under the permissions dropdown. But i am not getting any hit on my api when i make a comment. I and tried commenting using the user which created the page, page as user, and even with the graph api. but its not sending any response to api. So i thought maybe something to do with the API. But when i tried the messaging option and set up the webhook for that, i am getting the message through the webhook and its working fine. So that means the API is not the issue, and something to do with facebook permission or some other things. So i subscribed to every permission in that page and i am still ot getting any response for the feeds.
So an i missing something? For the facebook page webhook? If anyone went through this kind of an issue please provide your insight. I am stuck with this for a while and seems to going in circle.

I am building a e-commerce platform in WhatsApp using WhatsApp Business API. I created and connected the catalog using Facebook commerce manager. But I was not able to display the categorized collection of my products. It is displaying in WhatsApp catalog like a whole list. I need to categorize it.

I tried creating sets/collections in commerce manager but couldn't find a way to reflect them in WhatsApp catalog.

I am trying to implement Embed the Signup Flow for WhatsApp. I followed the documentation exactly and used the code provided:
Login with Facebook
However when I click the button, I just get {authResponse: null, status: 'unknown'}
The login window pops up and I can go through it until the end and authorise the app, but I do not get any authResponse object returned. I can still see that the apps granted the permission - when I call the /client_whatsapp_business_accounts endpoint, but I have no way of connecting the business accounts to the specific user on my application who granted the permission, I need to see the response on the page so I can immediately assign the correct profile to the correct person.
What am I missing?
