invite friends to created event using Graph API javascript - javascript

on my website users can already create facebook-events, but I can't figure out how to invite a list of selected user' friends to the newly created event by using the Graph API in javascript.
I already found lots of code examples using PHP but none using Javascript.
This is from the fb developer site:
"You can invite multiple users by issuing an HTTP POST to
/EVENT_ID/invited?users=USER_ID1,USER_ID2,USER_ID3."
but what code do I have to use to do so? My last try was:
FB.api('/EVENT_ID/invited?users=USER1_ID,USER2_ID','post', function(response) {
alert(response);
}
I've been searching for days now, please help me :)

I just discovered that you'll get a 200 error if you try and add the access tokens UID to the invitees list (yourself basically)... Took this into the graph explorer and kept trying my command, removing one UID at a time, and once I locked onto the offending UID the rest went through fine.

ContactsApp.createContact() You do not have permission to perform that action

I'm the admin for my google suite site. As of 2 weeks ago I keep getting the error "You do not have permission to perform that action." when trying to add any contacts programmatically. I've tried adding apis, removing permissions and reauthorizing, copying and pasting the script into new script files, copying the whole sheets files and nothing works. I've used different emails and names etc. I'm running this from my admin side and it worked fine a couple weeks ago.
This problem only happens with the line ContactsApp.createContact() and all other ContactsApp. methods work fine. I've tried all the suggestions I can find online and nothing is working.
function testthis(){
ContactsApp.createContact('Bob','Burger','testthis#gmail.com');
};
Any help or suggestions or troubleshooting would be greatly appreciated on this!
Make sure that this scope:
www.google.com/m8/feeds
is added and also make sure your Contacts API is enabled in your Google Dev console.
I also had this problem. In my case, the error was originated in the fact that the format of the input data was not correct. For instance, if you are adding to your contacts an email address, check that this field has actually an email format, otherway the script may not perform.

Automating posts from "company" for the Facebook page of said "company"

I put company in between quotations because my question relates to our Rugby team page but in Facebook it acts like a company page.
I am currently rebuilding my teams website (BBRFC Celtic) and I am going to add a user login system which will have coaches and admin staff with different levels of authority.
Sometimes due to weather conditions, events, or other things a training time may be changed or a match canceled or other various events. When these happen we normally send emails through a mailing list or sms or post on Facebook by hand.
What I want to have is a little bot of some kind that runs behind the scenes of the server and when coaches or admins change something it allows them to make an automated post to Facebook.
Something like after changing a trainings time it asking Would you like this to be posted to the facebook page and groups?.
I have been unsuccessful in finding out how I would go about writing the code for this. Our webpage will use php but maybe this can be done with javascript?
Do I need to get a key to post something as if I were the page?
How about to the different groups we have?
Any pointers would be helpful since I am totally stuck not really programmatically but more conceptually, I do not know if this is even possible.
I will explain the steps you need to accomplish your goal for a website. Note that the documentation also explains the case of a mobile application and others. I used the facebook API before, however, not to manage groups/pages, hence, this post will only point you in the right direction. I will explain how to post a message as being the admin of the page, not sure if you meant facebook pages or groups.
First, the user need to log in with facebook. This can be done using Javascript and the facebook API. Their documentation provides a very detailed explanation with code examples etc. Note that i will explain for the case of Javascript, however, this could be done in php, ...
Once the user is logged in, you can retrieve all kind of information about the user, his pages, etc. I would suggest to retrieve the pages the user is managing, then check if your "company" is part of this list (note that you will need the manage_pages permission). If this is the case, the user can post a message in name of the page.
/* Retrieve pages the user is managing */
FB.api(
"/me/accounts",
function (response) {
if (response && !response.error) {
/* handle the result */
}
}
);
Now response is an object containing multiple fields (see the official documentation).
Now, if the user is an administrator of your page, you can post a message as a Page.
/* Post a message as a Page, use your page id */
FB.api(
"/{page-id}/feed",
"POST",
{
"message": "The match has been delayed to ..."
},
function (response) {
if (response && !response.error) {
/* handle the result */
}
}
);
If successful, the ID of the post will be returned as part of a JSON response (see doc)

Facebook API profile picture

I created a website for my Students Organization.
On that website there is a page where I list all the people who helped organize our Activities. Theres a picture of every member there.
To get the images, I used their facebook profile pictures.
I used http://graph.facebook.com/USERNAME/picture?height=250&width=250
This code did work a few days ago, but now the images dont seem to load. I followed the url and got a JSON object:
{
"error": {
"message": "(#803) Cannot query users by their username (user.name)",
"type": "OAuthException",
"code": 803
}
}
So it seems to me that facebook might have changed their security... (after googling I found out about some changes in their API 2.0 but I didnt fully understand that..)
This link does still seem to work if you have the userID, but I'm unable to get that userID because of the same error message through graph.facebook.com...
Is there still a way to get facebook profile pictures of people on your website or did facebook totally block this off??
Any help is appreciated!
If you want to use the data, you'll need to implement Facebook Login for your website, where the users can give their permissions to your app to use their data.
The username field is no longer accessible with the Graph API v2.0. There are at least 5-10 questions on this on StackOverflow today.
Look at the docs:

In facebook api, not getting relationships_status

For some reason, I can't get relationship_status for any of my users' friends via the Facebook API.
I'm asking for the right set of permissions: the scope is set to "friends_birthday,friends_location,friends_relationship_details"
I verified I have those permissions (checked via manual check of permissions for my app)
I verified I'm asking for the right fields.
FB.api('/me/friends', {fields: 'name,id,location,gender,relationship_status,birthday'}, function(response) {...
I verified when I ask for those fields in the Facebook explorer, I do indeed get the relationships_status for lots of people. (and I know I won't get it for everyone)
However, when I call it via javascript, the response includes everything but relationship_status for friends.
Any ideas?
Thanks!
You need the friends_relationships permission instead of friends_relationship_details, since you are fetching relationship_status of a friend.

JS SDK - Posting to a page wall

I am using the JavaScript SDK. I have an application that has publishing permissions and after certain actions are taken a post will be made to the logged in users wall like so:
FB.getLoginStatus(function (response) {
//we are authorized
if (response.status == "connected") {
var name = "Post name";
var body = "Post body";
var caption = "The caption";
var description = "The description";
var link = "http://www.facebook.com/mypage";
FB.api('/me/feed', 'post', { message:body,caption:caption,link:link,name:name,description:description}, function (response) {
console.log(response);
});
}
});
What I would like to able to do is post to a specific Facebook Page after a post is successfully made to the users page. Is there a way to securely pre-authorize an application to do that? Is this possible with the JavaScript SDK, or at all? I did some looking around and havn't found a definite answer. I'm looking at the FB documentation but find it to be a bit spotty in places. Could anyone tell me if this is possible? Any help or advice would be very much appreciated, thanks much!
Edit: my mistake, I should have supplied more info. Here is what I am trying to do:
var body = "The body";
var caption = "The caption";
FB.api("mypageid/feed", "post", { message: body, caption: caption }, function (response) {
console.log(response);
});
I am getting the error "this api call requires a valid app_id" however my page id is valid. When I call FB.init() I am passing my app id and it works for the first post to the logged in users feed.
Edit:
I have made the change the Igy suggested. Now I am getting the error:""(#200) The user has not granted the application the permission to automatically publish feed stories""
Now, as I said I am trying to post to a Facebook page. I have logged into the account that owns the page and I have gone to the app and clicked allow for the following permissions:
email,user_photos,publish_stream
When I am logged in with the account that owns the page and check my status:
FB.getLoginStatus(function (response) {
console.log(response);
});
I get "connected". Am I doing this incorrectly? Do I have to do more than just authorize with the account that owns the page? Is there a way to set allow permissions for a page? I did a little digging but couldn't find an answer.
Edit :
Ok, now what is happening is IF I am logged into the account that owns the page the post will be made to the page. If I am logged in with another account I get an id back as a response to the API call but it doesn't seem to be a valid object id. For instance I just got this back:
id: 499973616681852_507724422573438
if I go to http://graph.facebook.com/499973616681852_507724422573438
I get an "unsupported get request" graph api exception, which suggest that id returned is not valid. I feel like I am close here but I am missing something. Any advice would be appreciated, thanks again to all who responded.
edit: removed the link to the page,that was left in unintentionally.
It's good practice to try getting it to work in the graph explorer first. Note that on the top right you can select which application to run under. I just made a post to your page using /PAGE_ID/feed and it worked fine. You'll need the publish_stream permission. If you can get it to work in the graph explorer you'll know it's possible to get it to work in the JS SDK and you've just made some sort of syntax error.
Also note there is an open high priority bug report on some calls to the graph returning "unsupported get request". So even though the id you are getting back is invalid, check the page itself to see if the posts are appearing.
I also noticed that the user itself is getting the same error. Try https://graph.facebook.com/507724422573438. Is this a test user for your app? Might be worth trying this as a real user if so.
Since you want to post to the page as the page itself, you'll need to authenticate as a page and then use that access token when making graph api calls. I am not sure if you'll be able to then use this access token for any user, or only users that are allowed to manage the page. It would be best for you to use the graph explorer to do some experiments to find out.
