I have created a WhatsApp Business Platform Test account. I am able to send and receive the hello-world template message but when I send a test message without template(as specified by the api) it doesn't push it to the mobile phone. Strangely I get success response in both cases.

Url: https://graph.facebook.com/v15.0/11ZZZZZZZZZZZZZ/messages

Here are the jsons and their responses

{    "messaging_product":"whatsapp",    "to":"91ZZZZZZZZZZ",    "type":"template",    "template":{       "name":"hello_world",       "language":{          "code":"en_US"       }    } } {    "messaging_product":"whatsapp",    "contacts":[       {          "input":"91ZZZZZZZZZZ",          "wa_id":"91ZZZZZZZZZZ"       }    ],    "messages":[       {          "id":"wamid.HBgMOTE3MjkwMDIxMzYwFQIAERgSMjZCRkQ3RDc0RjM0QkNEZZZZZZ=="       }    ] } 

In these case I successfully receive message on the mobile

{    "messaging_product":"whatsapp",    "to":"91ZZZZZZZZZZ",    "type":"text",    "text":{       "preview_url":false,       "body":"Hello World Testing"    } } {    "messaging_product":"whatsapp",    "contacts":[       {          "input":"91ZZZZZZZZZZ",          "wa_id":"91ZZZZZZZZZZ"       }    ],    "messages":[       {          "id":"wamid.HBgMOTE3MjkwMDIxMzYwFQIAERgSQUJERkM2RUE1RTEwQTExZZZZZZ=="       }    ] } 

However I don't receive message on the mobile. Is there anything I am missing in the second case?

Our app already have business_management, whatsapp_business_messaging, whatsapp_business_management approval from facebook. The issue is when we try to subscribe to any business whatsapp number outside our business manager it gives us error of "error_user_title": "App not linked to a Business", "error_user_msg": "Your App is not linked to a Business or the Business doesn't have access to the WhatsApp Business Account.",

I have created a WhatsApp business App on https://developers.facebook.com/apps/

I am able to send messages using the API & Access Token

curl -X POST \   'https://graph.facebook.com/v15.0/FROM_PHONE_NUMBER_ID/messages' \   -H "Authorization: ACCESS_TOKEN" \   -d '{     "messaging_product": "whatsapp",     "to": "1650XXXXXXX",     "text": {"body" : "hi"}    }' 

I want to send the message in a WhatsApp group, any ways to achieve this?

We are using the official whatsapp business cloud api (with Make).

We are wondering if there is any chance we can send messages to groups we are list in?

I could not found any documentation about it.

Thanks!

I develop a page with login for Whatsapp API Cloud following those steps:

But the problem is whatsapp shows in pop-up: You don't have any WhatsApp Business Accounts.

and tell me to create an WhatsApp Business Accounts, that i already have in my bussiness account linked with my whatsapp bussiness number.
