Using gin framework, You can use binding function.

type Payload struct {
    Phone string   `json:"phone"`
}

func Send(c *gin.Context) {
...
   var payload Payload
   if err := c.ShouldBindJSON(&payload); err != nil {
       // handling error binding
   }
   data := Payload{
      MessagingProduct: "sms",
      To:  paylod.Phone,
   }
...
}
