looking forward to this aswell from a guild management point of view.

might allow us to automate even more of the stuff we're doing without you guys even knowing about

Oh hell yes. Finally. I started developing a live map just like MOS did, but in the end I didn't take it all the way through. No time, they had early access and it already worked for them, so why bother, right? Well, I had leaflet implementation that could let you scroll like GMaps and big plans for drawing on the map and stuff like that...

The leaderboards are amazing to check active guild members, except you need to log in every time and use a link that I provided in officer's area to get a nice list.

The OAuth implementation is HUGE for developers and potentially for me/us as guild managers. If I can auth my app to use my token to access the data I can myself already access...and every council member does so, we could be able to take care of the guild much easier. I can use the API call implementation I had for the map too!

Really looking forward to it.

Also with OAuth, if you trust the App, the possibilities are huge: something like WoW armory, TP buy/sell functionality via app/web...etc.

I love API's cuz they make life so much easier ( well GW2 life for that matter :P) . But... Signing in using our account names? Isn't that like saying "Hey, i have 340 gold in my wallet, would you like to hack me?" ?

Who are the programmers of these API's? If its Anet itself then of course its totally safe

Bhuni it is arenanet themself, they will also be the ones to generate and hand out the tokens, I think I read something that they will have it in your web-account-settings to regenerate one if you wish.

It is basically the same as allowing your Facebook or Twitter apps to do something for you. I am 100% sure that if it comes to manipulating your account in any way, the developer will have to ask (his app will have to ask) permissions just like FB/Twitter apps. E.g. you can decide not to give a permission to read your friends or access your bank/TP.

Oh I see, then surely it will be ok to allow to access my guild settings, but I'm still not sure of allowing it to read my inventory and my bank. Besides, why would I need to know how much gold I have? LOL

I promote the guild-related API's since it eases the councilors' lives !

Depends on what Anet decides to release. You could get access to friend lists and maybe even ingame mail and message people that you don't have outside contacts for. Or at least read your ingame mail to see what's up. Anet should hire me right now and I'll bombard them with ideas and make use of most the APIs with Anet stamped tools
