Facebook: How to set app test users as friends? - facebook

Question

1) I try to get an access token for my app as described in the docs:
To obtain an App Access Token, invoke the following HTTP GET request
GET https://graph.facebook.com/oauth/access_token?
client_id=YOUR_APP_ID
&client_secret=YOUR_APP_SECRET
&grant_type=client_credentials
The API will respond with a query-string formatted string of the form:
access_token=YOUR_APP_ACCESS_TOKEN
I get an access token with a strange splitter sign | as a result:
access_token=568852943149232|ah1X8cAXHKSvFrTrZ4XybG0GzR4
This seems to be in a conflict with the docs, because the first parameter is app_id (before the sign |).
2) Then I try to use the strange access_token to get friend's access tokens (it requires to make invisible test users friends):
https://graph.facebook.com/APP_ID/accounts/test-users?access_token=568852943149232|ah1X8cAXHKSvFrTrZ4XybG0GzR4
It returns:
{
"error": {
"message": "(#803) Some of the aliases you requested do not exist: APP_ID",
"type": "OAuthException",
"code": 803
}
}
If I remove the part before | (including the sign |) and make another request it returns another error:
{
"error": {
"message": "Invalid OAuth access token.",
"type": "OAuthException",
"code": 190
}
}
3) In result I need to make a 'friend' request from one user and response from another (described here):
https://graph.facebook.com/USER1_ID/friends/USER2_ID?method=post&access_token=TEST_USER_1_ACCESS_TOKEN
https://graph.facebook.com/USER2_ID/friends/USER1_ID?method=post&access_token=TEST_USER_2_ACCESS_TOKEN
I can't do that because I can't get these (users') access tokens on the step 2.
Is returning app access_token correct? If yes, how to use it?
Notice please: I make the calls from an address line of a browser, app owner in a logged-in state.

You need to replace APP_ID with your actual APP_ID
That's why you get this message.
{
"error": {
"message": "(#803) Some of the aliases you requested do not exist: APP_ID",
"type": "OAuthException",
"code": 803
}
}
If your app id is 568852943149232 and your app token is 568852943149232|ah1X8cAXHKSvFrTrZ4XybG0GzR4 then your call is
https://graph.facebook.com/568852943149232/accounts/test-users?access_token=568852943149232|ah1X8cAXHKSvFrTrZ4XybG0GzR4
That is indeed your app token easily verifiable by https://developers.facebook.com/tools/access_token
