}
]
}
]
}
}
the response error is "error": {

Answer 1

Make sure and correct the below things in send message endpoint request,
Don't need to pass body component if there are no parameters in the body text, if there are parameters then you need to pass only that parameters text in the separate object of parameters in index order
Don't need to pass the footer component because it is static when you create a template
the quick_reply button type, use type as "payload" instead of "text" in parameters
{
"type": "button",
"sub_type": "quick_reply",
"index": "1",
"parameters": [
{
"type": "payload",
"payload": "btntwo"
}
]
}

Answer 2

Below object worked for me
{
"messaging_product": "whatsapp",
"recipient_type": "individual",
"to": "{{message_to}}",
"type": "template",
"template": {
"name": "trns_btn_img_header_XXX",
"language": {
"code": "en_US"
},
"components": [
{
"type": "header",
"parameters": [
{
"type": "image",
"image": {
"link": "https://www.w3schools.com/html/pic_trulli.jpg"
}
}
]
},
{
"type": "button",
"sub_type": "quick_reply",
"index": "0",
"parameters": [
{
"type": "payload",
"payload": "btntwo"
}
]
},
{
"type": "button",
"sub_type": "quick_reply",
"index": "1",
"parameters": [
{
"type": "payload",
"payload": "btnto"
}
]
}
]
}
}
