@jpvgc45 you need to add attachment key to the carousel and json_message in the dispatcher
test_carousel = {
"attachment": { "type": "template", "payload": { "template_type": "generic", "elements": [ { "title": "Title", "subtitle": "subtitle", "image_url": "url of the image", "buttons": [ { "title": "visit", "url": "webpage url to open", "type": "web_url" } ] }, { "title": "Title", "subtitle": "subtitle", "image_url": "url of the image", "buttons": [ { "title": "Title", "url": "webpage url to open", "type": "web_url" } ] }, { "title": "Title", "subtitle": "subtitle", "image_url": "url of the image", "buttons": [ { "title": "Title", "url": "webpage url to open", "type": "web_url" } ] }, { "title": "Title", "subtitle": "subtitle", "image_url": "url of the image", "buttons": [ { "title": "Title", "url": "webpage url to open", "type": "web_url" } ] }, { "title": "Title", "subtitle": "subtitle", "image_url": "url of the image", "buttons": [ { "title": "Title", "url": "webpage url to open", "type": "web_url" } ] } ] } } } dispatcher.utter_message(json_message=test_carousel)
