how to resolve
"Facebook Platform" "invalid_request" "(#100) Parameter error: You cannot send messages to this id"
Do you have any idea ??
I try send a POST using NET and the parameters is
https://graph.facebook.com/v2.6/{my_page}/messages?access_token={my acces token} and body request I set a message text and recipient id in Json form
the id I get for app in the web, is id of a friend but An interaction was already made
What is missing ?
Same issue here, "Facebook Platform" "invalid_request" "(#100) Parameter error: You cannot send messages to this id"
I guess if the ID is the number in the url: https://www.facebook.com/profile.php?id=100010603771535 <--- thos one, or I need another that is not just here...
You should use the PSID and not the "default/normal" ID of the user. PSID can be retrieved from messenger extensions (I don't know if it can be retrieved from Graph API without connecting the bot - please, answer in the comments).
