I am facing this issue on WhatsApp Api integration how to fix this temporary token is created but from test number is not generating.

Trying to get my test number and continue to run into this error. Not sure if it's a permissions issue with a vague error message or if it's a genuine bug

I cannot move forward.

I'm following this tutorial https://developers.facebook.com/docs/whatsapp/cloud-api/get-started but on step 2 I can't create a test number, I keep getting a red message saying that test numbers is not working and I need to contact support. Is that a workaround besides killing my personal number to turn into a bussines number? I just wanna test some stuff.

Problem: I’m using the Meta WhatsApp Business API to send template messages. When I try to send the first message using Postman, I get a 200 OK response, but the message is not delivered to the recipient's phone. However, if the user sends me a message first, the API works as expected, and the message is delivered.

Here is the JSON request I'm using:

{   "messaging_product": "whatsapp",   "to": "91790******",   "type": "template",   "template": {     "name": "hello_world",     "language": {       "code": "en_US"     }   } } 

The response I receive is:

{   "messaging_product": "whatsapp",   "contacts": [     {       "input": "91790******",       "wa_id": "91790******"     }   ],   "messages": [     {       "id": "wamid.HBgMOTE3OTA0NjMwMzM3F***dfdffQkI1QzcwNTd**==",       "message_status": "accepted"     }   ] } 

I’ve confirmed that the template (hello_world) is approved and active. The API request returns a 200 OK response, but the message is still not delivered to the recipient unless they initiate the conversation by sending a message first.

Question: Why is the message not being delivered when sending it as the first message? How can I send the first template message without requiring the user to send a message first?

Additional Details: I’m using the Meta WhatsApp Business API. The template is approved, and the recipient's phone number is valid.
