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?

Hello,
I am facing an issue with creating test users in Meta for Developers/Facebook for Developers. The system displays the following message: "Test account creation is temporarily disabled. Please try again later." This problem occurs across all my accounts.
Could you please provide recommendations or alternative methods for creating test users in this situation?
Thank you for your assistance!

Hello, I'm implementing Facebook Core sdk to be able to run app facebook campaigns. I have a question about what should be added to an iOS and Android project so that campaigns are not limited in any way. I can see that for i need to add to project manifest/info.plist the fb appid, fb client id and fb appname and in iOS on app delegate I need to call: ApplicationDelegate.shared.application
Is there anything else that I need to call/configure for both iOS and Android since I can see some things mentioned in the documentation below: https://developers.facebook.com/docs/app-events/getting-started-app-events-ios/ like: advertiser id collectable, auto log app events etc.

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.

We are applying for the instagram_business_basic scope and have provided a test IG account to the reviewers. However, the feedback we received states: "While reviewing we are unable to process as provided Instagram credentials are leading to a 2FA." Unfortunately, we are unable to disable 2FA from the Instagram app, nor can we provide access to the reviewers through backup codes.
What are the possible ways to ensure that the reviewers can successfully log in to our IG account?
