I am trying to send a message using the "Text Message" message type by executing the "/PHONE_NUMBER_ID/messages" endpoint in postman. There is no error in the response but the message is not delivered to the target phone number.
But if I use the "template" message type, the message is successfully sent.

After reading the documentation, I think I found why the message is not delivered. I think it's related to the user-initiated or business-initiated message behavior.

Hello Tibyan,
Can you refer to the following docs: https://learning.postman.com/docs/sending-requests/troubleshooting-api-requests/
