How to discard old reactions in a Facebook Live video? - facebook

We've been developing an interactive product for Facebook Live Videos when people can "fight" (i.e. choose between multiple options in things like videogames and so) using reactions.
The problem is that as we have more things than reactions we obviously have to use the same reaction for more than one thing, so old reactions are accumulated and the result is not really accurate. We tried to mitigate this by assigning reactions to the battles in a given order so people must change them through the live streaming, but people who react but then go away leave us with lots of reactions that don´t correspond to the current battles
So, is there any way to discard old reactions? Facebook Graph API only returns the user and the reaction but nothing else like the time or anything that can be used to discard them...

How to retrieve Facebook home news feed for apps?

I am currently attempting to retrieve the news feed from my Facebook home feed to include into an app. I know this used to be able to be done with the API however I have heard that it has since been removed. Is there any other way that you know of that would work or has it been added back into the API? It doesn't make sense why they would remove it.
No, there is no way to get a user’s feed via API. That used to be possible in the very early days (API v1), but has long since been removed.
It doesn't make sense why they would remove it.
Apart from user privacy (I don’t want my posts getting analyzed by some shady app with a developer located in $godKnowsWhere, just because they appeared on the feed of a friend of mine who might be using questionable apps), Facebook considers this a “core feature” – and 3rd-party apps are not supposed to replicate those in the first place. Facebook wants to make money from showing me ads when I view my feed, so allowing any other app to perform the same functionality would just mean loss of revenue.

Facebook pixel fires always not only after ad engagement

i am just starting with facebook marketing and have a question about the facebook pixel. We create a campaign with ads, created the facebook pixel and added it on the website for the purchase event. Thats all good and works, but we see that the pixel fires always, where it should only fire when the person who purchased something actually came through the ad. I thought that the pixel would only fire if a person came through the ad to the web site. Is that wrong (I mean it looks like it is wrong), or differently asked, how can we measure which purchases were initiated through the ad, or can the pixel only fire for people that came through the ad?
Thanks a lot!
Ok, i at least found out a few things:
The pixel fires always. Doesnt matter if a person came through the ad, or just came to the website from somewhere else. That means that the pixel statistic is not helpful in that way.
To see conversions from an ad, the report directly for the ad (or adset) is the place to go. There is a field for "Result" which should show the number of conversions that you defined for the ad set to be tracked.
Dont mistake the result field with the website conversions. I thought that this number should be the same but it is not. Website conversions tracks all conversions, even if the adset is configured to only track one specific conversion.
I still find it a little confusing, and not all doesnt make sense yet. But at least a bit better already.

Exporting posts from a Facebook-event to a group

My friend recently passed away and me and another friend was asked to estimate how many people would come to the funeral. I did this by creating an event, inviting those we thought would want to come. On the event-page people started sharing their memories through text and pictures. This was nice for everyone involved, but the question now is there any way to export these posts? It's would be sad to just see them fade with the event.
As far as I can see there's no way to share the posts to another group, nor convert to event to a group.
If anyone could suggest another way to this, either through code or a Facebook functionality I would be grateful.

App insights drop for all games on 14-15th Sept?

I noticed that across all of my facebook apps there was a significant drop in users between 14th-15th September. After spending some time investigating any possible cause (as I had launched an update that day), and finding nothing, I looked on appdata.com and it seems that almost every game has this big drop on the same dates.
I have checked the blog and couldn't see anything obvious to say why this might be. Does anyone know the cause of this change in insights data? Or is this a bug?
They changed the way that the number of active users was calculated. According to here:
Facebook has changed the way it calculates the total monthly and daily active users (MAU and DAU) for apps on the social network, sending figures plummeting.
The adjustment means that users who choose not to authenticate after a permission dialog box is clicked, and those who visit an app but do not log in, will no longer be contribute towards active user counts.
As a result of the changes, some games have seen more than half of their previously reported user figures drop away (though these changes have made no difference to the actual traffic each game sees).
facebook changed how user's bookmarks appear on sept 13th, which meant that a lot of users that used to see your bookmark on the left side of their homepage no longer could. As of that date facebook seems to use way less space to list bookmarks, only showing bookmarks for apps you use a lot or have just used. The only way to counter this is to educate your users to set the bookmark for your app as a favorite, which gives that bookmark a permantent position (hopefully) forever in the top section of the left margin of their homepage.

Facebook High Scores Server

I want to merge my High Scores with facebook.
In other words, I don't want to mantain my own score server but I would like to let make the dirt work to facebook.
So I want to publish new scores and retrieve them to display in my game.
Can I do it? What API can I use? Is it possible with REST?
EDIT: Many games in fb show global scores & friends score. How can I do it?
You could write data to fb with this: http://wiki.developers.facebook.com/index.php/Data_Store_API_documentation
However, i'd reccomend using a more stable mature platform like Google app engine. Facebook's API's have been extremely flaky lately, and when I was using the facebook datastore, I'd often find it to be slow and even worse, return inconsistent results.
