I'm attempting to integrate PayPal with a registration system I'm working on, and I'd like to give them multi-line transaction descriptions. I looked through PayPal docs and I couldn't find anything about discounts. I tried to put it as an item, but PayPal won't except negative value items. Does anyone have any ideas or know what I could do? Might I be stuck making transaction information through a database on the registration system? Thanks in advance!

I'm trying to access the soundcloud api. I know you need to register an app and be approved to get a token. However it seems the link to do it is currently disabled. I'm wondering if there is alternative route I can try or email I can reach out to. Any insight on this is much appreciated!
As of the time of posting, you can't. On the right hand side of their API docs, "Register App" is crossed out and noted as Unavailable.
This is most likely due to the reason that they are cutting server load to reduce cost, as they run out of runway (VC funding).

I am very confused by Paypal's site. Does anyone have any direction on how to setup Paypal knowing the following information?
I need users to be able to invoice and use credit cards.
There will be a value that is unknown until the time of checkout.
With Paypal, they want to see certain POST variables to know who you are, how much is being charged, if there is tax etc... In the past, I have just written some javascript functions to adjust these values before they are submitted.
For example, here is the paypal documentation. https://www.paypal.com/us/cgi-bin/webscr?cmd=_pdn_xclick_techview_outside
Creating a javascript function to change value="12.99" to value="Whatever" before the user clicks the Pay Now button is one way to do it.
Knowing more about how this value is created etc, would determine how the javascript (or JQuery) function looks.

Is it possible to get the login locations of Facebook users through the Facebook API or without authenticating as anyone?
For example, I want to know whether a user has logged in from a particular place. All I have is the URL of this user's public profile.
No, you can't - imagine the security implications if you can find out where anyone using Facebook has been logging in from.
This is common sense.

I'm trying to collect posts from public Facebook users that have a certain word such as, holiday, marriage, etc. What are the best tools and approaches to collect this data?
Use an implementation like this:
https://graph.facebook.com/search?q=Microsoft&type=post&fields=link,message&access_token=YOUR-API-ID|YOUR-APP-SECRET
It fetches results like you have requested. Make sure this call is going on at your server, so that your API ID or API Secret is not exposed.
P.S. If you do not have an app setup, visit Facebook Dev Page
Cheers.

Based on how things are done for my company, we issue updates very very regularly. Is there a limit or regulation as to how many times you can send a new update submission for your app?
I have looked and googled for anything relating to this issue but haven't found anything yet.
Thanks in advance.
Simple answer. No, there is not. You can submit as many updates as you can produce. Naturally, you will have to wait for acceptance to submit the next version while one is in review though.
