I want to send image message but when i will send image message from postman it shows it sent but i don't received and when i reply test message than image will send and i got that image message.
Because i am working on automatic bulk message sender so it is not reliable to tell every customer to first reply message than i can send you image message. Please help me to figure it out and how can i send images without any reply.
