I have been developing an iPhone application for push called notifications : www.appnotifications.com I've added Gmail push, RSS, Google voice, I provide an API for sending yourself notifications, and of course I've added Twitter too. I've had some support from some Twitter developers and I'm happy I did. However, to reply to the subject of this thread I also had many issues with the API, some tweets not showing up for example. The complains I get from users is all about the Twitter plugin I did, I almost regret to have added it. I might have done something wrong on my side, but I also have the feelings, like other people here, than the API is not always working well. And I don't blame anyone, I think with the number of tweets you have, and the massive number of new users you had within the last year, it must be a super exciting job to work at Twitter, but also such a stressed one :) I wouldn't want to be responsible for scalability there. Is there anything we can do to help you guys? Reporting specific bugs (they are sometimes hard to find and hard to reproduce as it's a stream).
[twitter-dev] Re: Comments for the group and Twitter staff
I seem to have opened a door that let in something ugly. Apparently I'm not the only one with concerns but at least I don't have a live application running that requires constant massaging. I believe my original question has been answered for now. Twitter guys: Since I'm currently unemployed I might be able to do some of your grunt work while you address the concerns of other developers. Is there anything I can do to help?

I stopped development on the project because the API does not yet seem stable enough for me to try to produce a marketable product on my own while at the same time chasing an API around.

[twitter-dev] What constitutes an update?
Hi Everyone, I'm busy developing a system that uses the Twitter API and i'd like to know what Twitter classes as an update? Following a user? Retrieving direct messages? Replying to a direct message? etc The reason I ask is because I want to count each update that the system makes so that I can ensure it stays below the limit of 1,000 updates per day. Thanks in advance, Craig

This. I've always thought that the obvious path would be to have unique error codes that never change. So if there's an auth fail it returns 1234 and 1234 corresponds to a specific message that is called externally. So we send the error code we're getting and it replies with the message and a description. So say they decide to change auth fail to auth has failed developers see no changes, unless they're using the twitter error message and then the message changes. So we have unique error codes that, when requested, return an error message that can be changed whenever you guys like and has no affect on developers and their apps. So for debugging we can simply call the description and error message from the code, but in a live environment we can build our own error handling based upon the error code, without having to constantly watch out for changes.

I believe that search does not return statuses of protected users (even when authenticated, though I may be wrong and should be corrected if I am).

Is there a specific way we can construct our request to mitigate the

Maybe the Twitter cookies that are returned back on each request?
Currently, we don't pass them back on subsequent requests because they
shouldn't be necessary, but if it will make some of the bad JSON
responses go away, I'll spend the time to implement it..
These bad json responses have been a problem for over a month now and
while I realize it is a difficult problem to track down, the fact
remains that the API is not functioning correctly.

[twitter-dev] Re: Comments for the group and Twitter staff
For applications like yours, moving to the Streaming API will increase the quality of service for you and decrease load for us. A big part of building an effective application on our API is figuring out which methods to use and what strategies to use for retrieving information and sending updates and direct messages. If you reach out to us (a...@twitter.com), we're happy to help with that. Often times, we don't hear from unhappy developers until they're already outraged and posting on their blogs or in this group. Please: give us a chance to help you out first. We may not always be able to make your particular issues our highest priority, but we'll give it our best shot. If you're still pissed, then you can go vent :) And yes, reporting bugs with detailed debugging output (HTTP requests and responses with all headers and full response bodies) are incredibly useful. We essentially can't help you without this information for any non-trivial bugs. Another huge help to us: if you know anyone who either wants to join our team as an engineer or help us out with full- or part-time developer support, please send them to http://twitter.com/jobs. We're a very small team with a very big job, but we've got the funding to add more people. Please, please, please send good people our way! Every addition to the team helps us help you.

[twitter-dev] Re: non json response
hi naveen.
we are most certainly working on it.
the best way to mitigate the error case is to actually do what the
response tells you to do -- in all cases that i've seen the http 200
error, there has been a refresh header (Refresh: 0.1). simply obey
the header, make a subsequent request in 0.1 seconds, and more likely
than not, you will receive your request. in general, be strict in
what you send out, and be lenient in what you accept is a pretty good
philosophy to follow. an additional strategy to try: if you receive
an error, then try again with some form of exponential back-off.
if you do see the error, please either send me, personally, a tcpdump
of the issue, or attach it to the issue on http://code.google.com/p/twitter-api/issues/detail?id=1024
.
thanks!

[twitter-dev] 403 and 503 errors from search API
Anyone else noticing more error messages than normal from the search API? I'm getting quite a few 403 Forbidden and 503 Server Unavailable errors. I looked for the Retry-After that would indicate rate limiting and don't see it. Thoughts? Thanks. Michael Paladino http://tidytweet.com/ http://tidytweet.com
[twitter-dev] Re: non json response
I agree with John that to achieve higher user visible reliability, API
requests should be wrapped in a retry loop.
However, PLEASE, PLEASE, PLEASE, do NOT use linear backoff, i.e.,
subsequent retries are delayed by an amount of time chosen uniformly at
random up to the same maximum amount for each retry. This will lead to
disasters for all API users as failed API requests, when retried, will
tend to bunch up in ever increasing bunches, leading to a higher, not
lower, failure rate.
You should instead use exponential backoff, where the maximum amount of
delay time increases for each retry. Queuing theory and experience
indicate that the optimum factor used to increase the maximum delay for
each retry should be 2.0.
The earliest implementations of both Ethernet and TCP, and I'm sure
other protocols, tried linear backoff and experienced this problem in
spades. When the backoff was changed to exponential, the problems
miraculously went away.

Subject: [twitter-dev] Re: non json response
I've been following the internal dialog on tracking this issue down.
Given what we know, I don't think there's anything that you can change
to the request parameters to reduce the chances of this happening.
From a given client, the chances of this happening to a request are
pretty close to random. Different clients, however, seem from the
outside to operate differently, as they tend to routed through
different infrastructure. There also may be differences in the quality
of the code, especially around how errors are handled.
If you want higher reliability, I'd suggest wrapping nearly all
network API calls in a retry loop. If you get any sort of error: tcp,
http, parser, etc. retry with linear backoff.

Is there a specific way we can construct our request to mitigate the

us through whatever filter is returning the bad data?
Maybe the Twitter cookies that are returned back on each request?
Currently, we don't pass them back on subsequent requests because they
shouldn't be necessary, but if it will make some of the bad JSON
responses go away, I'll spend the time to implement it..
These bad json responses have been a problem for over a month now and
while I realize it is a difficult problem to track down, the fact
remains that the API is not functioning correctly.
A response from the twitter team would be greatly appreciated.

[twitter-dev] Batches of suspended users added back to social graphs
I'm noticing from id lists pulled this morning that overnight there appears to have been a large number of suspended ids added back to various accounts. Have I just not been watching closely or has anyone else noticed this? Randy
[twitter-dev] Re: Comments for the group and Twitter staff
I completely agree. As I said, we can't always make someone's pet issue our top priority. Given that we have basically 2.5 full-time engineers on our team, that can mean waiting weeks or months for a fix to a lower-priority issue. But we should absolutely be communicating during that wait, and the author of that post has every right to be pissed. One thing I have noticed, though, is developers going through our user support track (via http://help.twitter.com) rather than contacting the Platform Team via a...@twitter.com or by filing an issue on our issue tracker. Our user support folks try their best, but they're often not able to answer developer questions and are likely to hand that issue off to our team and close the ticket. Contacting us developer-facing folks is a much better way to get your issue answered.

[twitter-dev] Re: Comments for the group and Twitter staff
Generally, the folks on the Platform Team aren't set up with accounts for the user-facing support system. That's why we try to keep things on the Google Code issue tracker - it's in public, it's easier for our team to manage, and it's easier for other developers to discover bugs so we get fewer duplicates.

If they deny, you shouldn't get an OAuth authorization token back. Can't you just check for that? Am I mistaken here? Do you always get a token back that just happens to be invalid if they deny?

[twitter-dev] Re: Detecting denied condition on Twitter oAuth page
No, the oAuth login page doesn't provide oAuth access tokens (regardless of whether the user approved or denied) To get the oAuth access token, apps need to make a seperate oAuth GET call (after the user has approved access on the oAuth login page) On Sep 16, 2:36 pm, JDG ghil...@gmail.com wrote: If they deny, you shouldn't get an OAuth authorization token back.

[twitter-dev] Posting non-English Characters using OAuth
Hello, I was hoping someone could help me, or point me in the right direction. I've written an app that used basic auth for a while, and of course that worked great. I'm now working on switching to OAuth, and everything worked perfectly until I tried posting a status update that used non-English characters, such as the following Japanese: 日本犬 In this case, I get a 401 Unauthorized error. I've looked at the signature and the encoding of the parameters, and it appears as if everything is being processed correctly, but it's possible I missed something. I'm using C#, and the OAuth implementation I'm using can be found here: http://www.voiceoftech.com/swhitley/?p=681 The only changes made to that code involve adding support for the PIN when first authorizing an account, but that isn't relevant to this. Any help would be much appreciated, I'm not sure what to try at this point.
