Persistent menu not showing in Facebook Messenger chat bot - facebook

Question

As I don't know why suggested, using Postman.
Per docs, have succesfully POSTed the configuration to facebook APIs:
which is not supposed to be anyways locale specific. Even I don't see here
Localization: Developers can now provide text in multiple languages (or entirely different menus) for each local your bot's users may come from.
Like my brother, I have tried almost everything so far
This looks like some crazy bug. Is there some work around to add a simplest persistent menu?

Answer 1

Wasted 2 hours on this issue. Until I realised you have to delete the conversation then refresh facebook with ignore cache (ctrl+shift+r in chrome) and then it will show.

Answer 2

The FB API document states that the API link to hit for applying persistent menu to the page specific bot is:
https://graph.facebook.com/v2.6/me/messenger_profile?access_token=<PAGE_ACCESS_TOKEN>
Notice the me after version number i.e v2.6 in this specific case. However, this did not worked for a lot of people
There is small change in the API link to hit:
graph.facebook.com/v2.6/Page ID/messenger_profile?access_token=PAGE ACCESS TOKEN
Notice that me is replaced with the fb Page Id.
And the sample payload can still be the same:
{
"get_started": {
"payload": "Get started"
},
"persistent_menu": [
{
"locale": "default",
"composer_input_disabled": false,
"call_to_actions": [
{
"title": "Stop notifications",
"type": "nested",
"call_to_actions": [
{
"title": "For 1 week",
"type": "postback",
"payload": "For_1_week"
},
{
"title": "For 1 month",
"type": "postback",
"payload": "For_1_month"
},
{
"title": "For 1 year",
"type": "postback",
"payload": "For_1_year"
}
]
},
{
"title": "fresh jobs",
"type": "postback",
"payload": "fresh jobs"
},
{
"title": "More",
"type": "nested",
"call_to_actions": [
{
"title": "like us",
"type": "web_url",
"url": "https://www.facebook.com/nordible/"
},
{
"title": "blog",
"type": "web_url",
"url": "http://xameeramir.github.io/"
}
]
}
]
}
]
}
Notice that it is mandatory to configure get_started button before setting up the persistent_menu.
