I'm trying to send test message on WhatsApp Business API it took a day until I was shown a test number on "from" option now I need to register the test phone but don't know how.

the register link take me to the configuration page, but there is no option to register

Here is my WhatsApp account:

Is there a way to send a message to multiple recipients in one post request? The same way I send emails separated with a semicolon.

I have deployed my webhook and connected my WABA. Once I send an image to this business account. It did not return the media id from the response. Actually, the JSON returned to me like this:

{     "entry": [         {             "changes": [                 {                     "field": "messages",                     "value": {                         "contacts": [                             {                                 "profile": {                                     "name": "XXXXXXX"                                 }                             }                         ],                         "messages": [                             {                                 "from": "XXXXXXXXXX",                                 "id": "wamid.aisjdoiajsodiajsodasd\u003d",                                 "timestamp": "1657527108",                                 "type": "image"                             }                         ],                         "metadata": {}                     }                 }             ],             "id": "124071984791824"         }     ],     "object": "whatsapp_business_account" } 

Or should I try the Whatsapp On-premises API? https://developers.facebook.com/docs/whatsapp/on-premises/reference/media/media-id

As I mentioned above, are there any API's available for uploading status (text, images and videos etc.) in the WhatsApp Businesses platform? For businesses messaging we can use Cloud API https://developers.facebook.com/docs/whatsapp/cloud-api or On-Premises API https://developers.facebook.com/docs/whatsapp/on-premises . Like messages API's, I am searching for status uploading API's. If anyone knows about this please guide me.

I've installed WhatsApp business client on my linux docker containers, I have managed to hit the /v1/health route perfectly and have also changed the default password through an endpoint.

But, I'm getting an error when I try to access POST request /v1/contacts . The error is:

{     "meta": {         "version": "v2.41.2",         "api_status": "stable"     },     "errors": [         {             "code": 1014,             "title": "Internal error",             "details": "Connection refused. Please check if wacore is running: wacore:6251"         }     ] } 

However, my wacore container is indeed running:

P.S: Some questions already posted here with similar titles don't solve my issue.
