We have carried out a review regarding our blocked account And explains what we use in sending WhatsApp messages using the API from meta.
But our review was rejected. Honestly we don't know why this happened.

The API has started returning an error message, "Unsupported Audio mime type audio/opus. Please use one of audio/ogg; codecs=opus, audio/mpeg, audio/amr, audio/mp4, audio/aac," when attempting to upload audio files.
Similar files were successfully uploaded just days ago without any issues. This error began appearing on May 1, starting at 9 AM UTC. I’ve attached a sample screenshot of the file we are trying to upload.

Hi, can you guys help us to solve this issue?
We are currently setting up our development meta app to webhook. But we had issue when we want to verify our webhook url callback with verify token with it, it said that:
Callback verification failed with the following errors: curl_errno = 35; curl_error = OpenSSL SSL_connect: SSL_ERROR_SYSCALL in connection to (our dns webhook:443); HTTP Status Code = 200; HTTP Message = Connection established
We already prepare our url webhook with logic to return hub challenge as documented in https://developers.facebook.com/docs/graph-api/webhooks/getting-started/#create-endpoint. We also had our WAF, Load Balancer, and our app server injected with cert SSL properly.
For additional information, we can access our webhook url on postman or web browser and it can return the hub challenge that we set on url query params.
Is there any SSL Certificate from META that we have to inject to our environment? or the steps that we do to inject SSL Certificate are incorrect? Do you guys have same issue like us? please let me know how to solve this issue.
Thank you

I'm currently exploring the capabilities of the WhatsApp Business API for a project I'm working on. I'm wondering if the WhatsApp Business API supports sending messages to WhatsApp groups. I've read through the documentation, but I couldn't find a clear answer on this specific feature.

Could someone who has experience with the WhatsApp Business API clarify whether it supports sending messages to WhatsApp groups? If it does, are there any specific limitations or requirements that I should be aware of?

POST = https://graph.facebook.com/{{Version}}/{{Phone-Number-ID}}/messages Body = {     "messaging_product": "whatsapp",     "recipient_type": "individual",     "to": "{{Recipient-Phone-Number}}",     "type": "document",     "document": {         "link": "https://test.pdf",         "filename": "Test"     } }
