Messenger: attachment type 'video' not working correctly? - facebook

Question

According to https://developers.facebook.com/docs/messenger-platform/send-api-reference/video-attachment I should be able to send video's via messenger. I ideally want to send youtube videos with a start and end time, but that does not seem to work.
I am currently trying to get it work in any such way, so i have the video on FB currently and even that isn't working.
python code
data = OrderedDict()
data['sender'] = {"id": APP_ID}
data['recipient'] = {"id": recipient}
data['message'] = {
"attachment": {
"type": "video",
"payload": {"url": "https://www.facebook.com/587721184763189/videos/596530243882283/"}
}
}
data = json.dumps(data)
print("data: ", data)
r = requests.post("https://graph.facebook.com/v2.6/me/messages",
params={"access_token": token},
data=data,
headers={'Content-type': 'application/json'},
timeout=60)
if r.status_code != requests.codes.ok:
print(r.text)

Answer 1

You need to supply the URL to the video file (for example MP4), not the URL of page containing the video (for example a YouTube URL).
This can be seen in the example code in Facebook's documentation
curl -X POST -H "Content-Type: application/json" -d '{
"recipient":{
"id":"USER_ID"
},
"message":{
"attachment":{
"type":"video",
"payload":{
"url":"https://petersapparel.com/bin/clip.mp4"
}
}
}
}' "https://graph.facebook.com/v2.6/me/messages?access_token=PAGE_ACCESS_TOKEN"

Answer 2

Sending Youtube videos in your Facebook Messenger bot is now possible if you use the open graph template.
A message object would then look like this:
"message": {
"attachment": {
"type": "template",
"payload": {
"template_type": "open_graph",
"elements": [
{
"url": "https://www.youtube.com/watch?v=whatever"
}
]
}
}
}

As of today, this works (you need to add the image url of the screenshot):
message: {
text,
attachment: {
type: "template",
payload: {
template_type: "generic",
elements: [
{
title: "El espía",
image_url: "https://i.ytimg.com/vi/yj2r6KPKV1w/hqdefault.jpg?sqp=-oaymwEcCOADEI4CSFXyq4qpAw4IARUAAIhCGAFwAcABBg==&rs=AOn4CLAGKGjilp1gvYUv6c5dL_oveZ8LYg",
default_action: {
type: "web_url",
url: "https://www.youtube.com/watch?v=yj2r6KPKV1w",
},
}
],
},
},
},
