I have been trying to register my facebook whatsapp business account but it is not working. Am I using the correct api? Or what am I doing wrong? Note: I have passed the correct phone number id and a valid bearer token. This is the response i get. How can I resolve this issue? Has the endpoint changed?

Hello Meta Support Team,
I am currently working with multi-product lists in WhatsApp's interactive messages and have a question regarding localization. Specifically:
Does the platform support sending a language code along with the interactive message payload? For example, if I have a localized catalog (using the catalog ID), can I specify the language code so that the correct localized version of the catalog is displayed to the user? This feature would be incredibly useful for providing a seamless experience to users in different regions. I would appreciate any guidance, documentation, or examples regarding this functionality.
I appreciate your support!

Hello,
I am encountering an issue with the WhatsApp Business API when attempting to send a message template or query the list of templates. The API returns the following error:
{ "error": { "message": "(#135000) Generic user error", "type": "OAuthException", "code": 135000, "error_data": { "messaging_product": "whatsapp", "details": "Generic user error" }, "fbtrace_id": "Acl4jwcxw9wDcwCcNs-_4jW" } }
Relevant Information:
The template used is approved in the Business Manager. The recipient's number has been tested and is in E.164 format (e.g.: +5511999999999). The access token used has the correct permissions (whatsapp_business_messaging and whatsapp_business_management). The phone number is active and linked to the WhatsApp Business account. Sending individual messages continues to work The problem occurred without any changes, sending templates simply stopped working.
Attempts to resolve:
I checked the template parameters and they are correct. I confirmed that the access token is valid. I tested with other templates and other phone numbers, but the error persists.
Has anyone faced this issue or know how to solve it? Is there anything I can check or adjust in the template configuration, or in the WhatsApp Business account to solve this? Is there a support channel by phone or email with Meta?

i have two distinct apps, each with its own phone number and webhook URL, are both receiving webhook notifications intended for one of them. This could lead to confusion, incorrect data processing, and potential security risks.

Messages were being delivered just fine, I created a new template that was approved and I sent with it a 5 messages, then the messages stopped sending. Then whenever I send I get a response that It's sent but it never reaches the phone.
