Following up on my previous post, I see that each call to PostItem.aspx to submit post states results in a reponse with "the current state of all posts in any feed where read state has changed since the last sync."

This means that for every call, I receive a response of over 700kB, which takes anywhere from 1.5 to 4.5 seconds. That's a lot of bandwidth and time for a call that happens so frequently (in my case, to mark a post or group of posts as read).

I am not currently using any of the information in this response, so I'd love it if you could add a flag that would allow me to specify that I want the server to limit the response body to a simple "OK" or error, something like:

Request Format: application/x-www-form-urlencoded

"loc=<locationName>&r=<postId>&u=<postId>&d=<postId>&q=<0|1>"

o loc – specify the location name to submit the read state changes (OPTIONAL)
o r – mark a post read (can be specified multiple times)
o u – mark a post uread (can be specified multiple times)
o d - mark a post deleted (can be specified multiple times)
o q - specify 1 to request a "quiet" reponse from the server (i.e., omit the current state of all posts since the last sync)

Also, the draft of the new REST API documentation I have implies that this list of current posts should be limited to those that have changed since the last sync. However, I don't see how I can indicate when that happened. Should I add the last sync token from the location's OPML?

Thanks, all.

Hey Dan,

One of the API guys wants to go over this with you, we may have a beta API that you can use which could work better for you Wink . Can you shoot an email to NewsGator Support - I'll make sure it gets to the right guys.

I'm also having a problem with the PostItem call. I working in a low-bandwidth, low-memory environment, so parsing 600k of return data each time a call is made is not feasible (really, ANY call that returns 600k is a no-go for me). I'm trying to figure out how to work the ng:token value into the call.

My app follows this basic sequence:

- Call Subscription.aspx/ to fetch a list of feeds
- Call Feed.aspx/ for each feed to get a list of posts for that feed
- When a group of posts has been marked read, or a timer fires, call PostItem.aspx to update the server with their read status

I've tried passing ?token=reallyLongTokenString with the PostItem call (using both the token returned by Subscription.aspx and the one from Feed.aspx), but neither one seems to effect the output. Any suggestions?

Thanks!

Hi Ben,

In response to both yours and Dan's inquires, we have been working to implement the equivalent of the SOAP call PostItem.asmx/UpdatePostMetaData into the REST API. UpdatePostMetaData handles all of the read/flag state changes for a given feed/post. It definitely uses a sync token obtained from a previous Subscription.aspx call to keep results to a bare minimum.

We hope to have a working version available to you for use in the coming weeks, so hang on! Smile
