[ANNOUNCE] PubSubHubbub Feeds and other changes

[James Lee]

Hi all,

We have a couple of changes for folks using our beta Real-time Feeds api:

1) We've increased the max limit to 300. You can also get up to 300
listings if you use the time_offset and time_limit parameters. Limit
and offset parameters are _ignored_ when using time_offset and
time_limit. Here's an example call:
/v2/feeds/listings/latest?time_offset=1295890749&time_limit=10 We
hope these changes mean that fewer listings will slip through the
cracks between your polling of the feeds api.

2) Realtime Feeds via PubSubHubbub / Superfeedr

We are excited to announce the immediate availability of the same
listing feeds data via PubSubHubbub (PuSH). PubSubHubbub is a
protocol that allows us to push individual updates to you rather than
you constantly polling our feed. Although perhaps a little more
complex to set up, once running, you will no longer need to filter out
duplicates or make sure you are not missing listings because you are
not polling quickly enough. This method requires you to have an HTTP
server running at all times to wait for updates.

You can read more about PuSH here:
http://developer.etsy.com/docs/read/PubSubHubbub_Feeds
The key required for subscription will be the same key as your /v2/feeds key.

For beta access, please email us at deve...@etsy.com with a brief
description of what'd you'd like to do with the feed (if you already
have beta access to /v2/feeds, you also already have access to our
PuSH hub).

Thanks and let us know if you encounter any issues!

this is such a good move, really pleased that Etsy is taking this direction.

what would be really useful is if you pushed individual users/shops too. A lot of the existing apps seem to be directed at single etsy users so getting real time info for a single user would be great to have.

We're currently tracking 450k etsy listings for our users. Polling for changes to that many every 30 minutes is insane so right now we only check for new listings but etsians very often change the content of their listings, especially now there are so many cool apps that can do that for them.

so the only realistic way of making sure our data matches what is on etsy is for you to push data. I will personally come and make tea, wash dishes and serve cake for a week to the Etsy api team if you implement this :)
