I'm trying to implement a template with a carousel to send and render a variable number of cards (from 2 to 10) depending on the available information. According to Meta’s documentation (link): "It is only necessary to define two product cards upon template creation. An approved template with two product cards can be used to send up to 10 cards in a template message."
However, when defining the template with 2 cards and sending more than 2 in the message, only the initially defined 2 cards are rendered, and the additional ones are not displayed.
Steps followed to test this:
Step 1 - Defined Template
I created a basic carousel template with two cards.
{
"name": "carousel_test_v3",
"language": "es_AR",
"category": "MARKETING",
"components": [
{
"type": "BODY",
"text": "Template para probar cantidad dinámica de cards"
},
{
"type": "CAROUSEL",
"cards": [
{
"components": [
{
"type": "HEADER",
"format": "IMAGE",
"example": {
"header_handle": [
";
]
}
},
{
"type": "BODY",
"text": "{{1}} Este es el body del template",
"example": {
"body_text": [
[
"$1.905.062"
]
]
}
},
{
"type": "BUTTONS",
"buttons": [
{
"type": "QUICK_REPLY",
"text": "Ver más"
}
]
}
]
},
{
"components": [
{
"type": "HEADER",
"format": "IMAGE",
"example": {
"header_handle": [
";
]
}
},
{
"type": "BODY",
"text": "{{1}} Este es el body del template",
"example": {
"body_text": [
[
"$2.305.012"
]
]
}
},
{
"type": "BUTTONS",
"buttons": [
{
"type": "QUICK_REPLY",
"text": "Ver más"
}
]
}
]
}
]
}
]
}
Step 2 - Approved Template
Verified that the template is approved in business.facebook.
Step 3 - Sending a Message with 3 Cards
Sent a template message defining 3 cards in the carousel using facebook Graph API .0//messages
{
"messaging_product": "whatsapp",
"to": "+*************",
"type": "template",
"template": {
"name": "carousel_test_v3",
"language": {
"code": "es_AR"
},
"components": [
{
"type": "BODY",
"parameters": []
},
{
"type": "CAROUSEL",
"index": 1,
"cards": [
{
"card_index": 0,
"components": [
...
]
},
{
"card_index": 1,
"components": [
...
]
},
{
"card_index": 2,
"components": [
...
]
}
]
}
]
}
}
Step 4 - Result
Verified that we are only receiving 2 cards, even though the message we sent contained 3. Result image

according to the documentation, you can send up to 10 product carousel cards not media carousel cards
