Im using restfb api for connecting facebook client and im trying to send message to facebook user(recipient) from facebook Page.

But it is throwing error: Received Facebook error response of type OAuthException: (#100) No matching user found (code 100, subcode 2018001)

and using this error code and subcode i found that recipient id i passed is wrong. recipient id i passed is generated by Graph API Explorer which returns as shown below and i used that id for recipient id { "id": "XXXXXXXXXXXXXXXXXXXX", "name": "YYYYYYYYYYYYYYYYYYY" }

so can anyone tell me how to generate recipient id of user.

You can not send messages to arbitrary users, you can only _respond_ to the messages they send your page in the first place. (And when you read those messages, you _get_ the user id from there.) – CBroe Aug 22 '17 at 14:05
