I need to send private message from my page (i am the admin) to user who already contacted my page
My reference on that this link
https://developers.facebook.com/docs/messenger-platform/send-api-reference
I am testing this feature via Facebook Graph Explorer
https://developers.facebook.com/tools/explorer
Using version V2.9
Request:
curl -X POST -H "Content-Type: application/json" -d '{
"recipient": {
"id": "USER_ID"
},
"message": {
"text": "hello, world!"
}
}' "https://graph.facebook.com/v2.6/me/messages?access_token=PAGE_ACCESS_TOKEN"
i replace the USER_ID with my id and access token of page i am admin of
But my response is:
{
"error": {
"message": "(#100) No matching user found",
"type": "OAuthException",
"code": 100,
"error_subcode": 2018001,
"fbtrace_id": "AeMT8VK2SbX"
}
}
I know it is required special permission pages_messaging so i am testing this feature using Facebook application Graph API Explorer not my application because it is not approved yet to use this permission
Any idea why i got this error ?
