When establishing a call using Twilio, many many POSTs are made to https://eventgw.twilio.com/v2/EndpointMetrics, and I've noticed in our javascript error tracking service that some of our users get 403s from these calls. In the last week, there have been 19 users getting 2,600 errors. Can anyone from Twilio tell me what the calls are, whether these errors are benign and I should ignore them, and whether there is any way to disable these? For a single short call I'm seeing 34 separate POST requests to this endpoint.
Can you check that when you get these errors, your clients Access or Capability token didn't expire?

I'm currently running a web application that uses Microsoft Graph's API and we encountered the following message today which severely impacted our application, for a whole day:
"error": {
"code": "ErrorTooManyObjectsOpened",
"message": "Too many concurrent connections opened., The process failed to get the correct properties.",
"innerError": {
"request-id": "removed",
"date": "2017-12-13T17:01:14"
}
}
please note that the request-id was removed
Let me summarize what our web application does.
Basically, we have 2 email folders that we are actively subscribed to, Junk and Folder A.
If anything hits Folder A, we strip the body of the email message and then move the message to Folder B. The subscription on our Junk folder also strips the body and sends them over to Folder B.
Sometimes the webhook subscription service skips messages that may come at the same time, therefore we have 2 cron jobs in our server that run a script and check Junk/Folder A for any messages every 5 minutes, therefore my assumption is that the cron job runs about 288*2 times per day. Not counting our subscription to the folders, we usually get around 200-300 email messages per day.
Unfortunately Microsoft's Graph error codes page does not provide us with any explanation about this code. I would really appreciate if anyone can explain what this means and how to avoid it from happening.
This is occurring because your application is exceeding the throttling thresholds.
There are several different throttling metrics that can affect Microsoft Graph requests. For a high-level overview, see the Microsoft Graph throttling guidance. Since in this case you're hitting Exchange Online via Graph, you can find more specific information from What throttling values do I need to take into consideration? in the Exchange documentation.
Architecturally, you are making a lot of unnecessary calls into the API. Rather than having both a subscription and a scheduled job, you should use just the webhook subscription and the /delta endpoint.
Each call to the /delta endpoint gives you a token that can be used to fetch any changes to a given resource since the token was originally issued. So regardless of if 1 email came in or 1,000, you only get the new emails.
Once you're using the /delta to find your changes, you then use a webhook only as a "trigger". When you receive the webhook, you can ignore the contents and instead issue a request to /delta. This ensures that you capture every incoming email even if you didn't necessarily receive separate webhook notifications.
There is a bug. After making 500 message move requests, a "cannot copy/move error" occurs. Subsequently, a "429: Too many concurrent connections opened" error occurs. Most applications miss the first error because you continually get the 429 error afterwards.
If you let the application "rest" for 30 minutes, the throttle resets itself and you can continue on. I do not think there is a time limit for hitting the 500 moves. My application did 500 moves after 6.5 hours and then we started getting the error.
And, if you keep trying your move call before the 30 min rest period, it never resets. Also, in the response, the retry-after is null... so, that doesn't help you.
If you find a work around, please let me know. We are trying a few things like setting the category, then manually moving the messages. I am also investigating making a rule the moves them for us or some other job. I cannot find a way to execute a rule from the Graph API.
See this link for more information. Also, the more people who report having this issue, hopefully the sooner it can be resolved. Outlook API Throttling documentation #144
I have coded a Fine bot which Tweets every 150 seconds time.sleep(150) . I have made a APP from twitter with Read / Write Permissions . But after 30 Tweets, Twitter Blocks the Application. So is there any way to Bypass it. ? Or has someone ever Tried bots in Twitter. Their are some grammar Bots, RT's Bot in twitter which has almost 110k Tweets and they tweet every 30 seconds .. How do they bypass the Frame Limit Protection
Specific Error Restricted from performing write actions and Code Stops.
The docs at least don't specify the rate limit rules, only that there's one. But it does state that you can not have duplicate texts. Is that the case possibly? What HTTP Error are you receiving? Since they don't explicitely post the rules that apply to the rate limit, I'd suppose they might have internal algorithms to tell if it's bot-like behaviour, which I'm sure they do not want to allow. Especially if you set up a new app, regulations might be more strict.
Edit:
If you're completely certain that you're not firing up too many requests at once (e.g. check with fiddler to make sure), then twitter suggests to get in touch and check the email address of the associated account for any mail from the operations team in order to resolve possible misinterpretations.

I faced the exact same problem with my twitter bot. I basically made a bot to auto-reply to a specific user and ran that script on cron of 1 minute. Got blocked even though my replies weren't spam but AI generated replies from https://qnamaker.ai/
My script is a bit heavy so it is not feasible for me to keep it running 24*7 as it'll create overhead on server system. But since you keep running it(picked that up because of the delay function), one thing you can do is keep changing the time interval in which your bot makes a tweet. Make it random so that it doesn't look scheduled and bot-like.
You can use the random class in python for that.
import random
y=random.randint(100,150)
time.sleep(y)
This way your code resumes after random intervals of time. This prevented my bot from getting blocked for a long time. Hope this helps.
Your bot seems to be banned, their algorithms probably flaged your posting as similar to spam accounts.
You should contact Twitter and explain the situation, using the following page:
Twitter API Policy Support, give them the details of why they should allow your bot to act as you wish.
Hey I'm developing an iOS application which communicates with an external web service in order to make various kinds of requests.
I'm aware of Murphy's Law "Anything that can go wrong, will go wrong" and that made me think about timeouts. Currently my application does not handle the situation when a request get completed and times out simultaneously. How should I handle such situations?
Without cooperation from the service provider there's not a lot you can do. If your app sees a timeout it cannot from that deduce whether the request actually completed or not. Could be it worked and something in the infrastructure failed to deliver the response, could be that it failed and hence you saw no timely response.
You have some actions you can take that will help the user. I assume that you have available to you the details of the request you attempted to send, your app should keep that locally. You are now in a position to do some useful things:
Some service authors allow you to safely submit the same request twice. So just resubmit, if it previously worked the service will just say "yep, already done that, here's the details|, if not it will just do the work as normal.
Some service authors allow you to query the status of previous request, so you can determine what has been done and what has not.
In some cases there is no IT system way to deal with the problem, the user will need to contact a help desk or call centre. Here having the details of what was previously attempted can be very useful.
When I make API calls to the server, I'm getting 404 errors for various data -- grades, role IDs, terms -- that I won't get on the next time I call it. The data's there on the server, viewable by the same user, and is often returned successfully, but not every time. The same user context will return data successfully for other calls.
Any ideas what could be causing this?
I'm using the Valence API with the Python client library and our 9.4.1 SP18 instance of Desire2Learn in a non-interactive script.
more detail: the text it returns on the bad 404s is " ErrorThe system cannot find the path specified."
It would help enormously to gather data about your case: packet traces that can show successful calls from your client alongside unsuccessful calls, in particular, would be very useful to see. If you are quite certain (and I see no reason you shouldn't be from your description) that you're forming the calls in the right way each time you make them, then the kind of behaviour you're noticing would seem to speak to some wider network or configuration issue: sometimes your calls are properly getting through the web service layer, and sometimes they are not -- this would seem therefore not to be down to the way you're using the API but in the way the service is able to receive that request.
I would encourage you, especially if you can gather data to provide showing this behaviour, to open a support incident with Desire2Learn's help desk in conjunction with your Approved Support Contact, or your Partner Manager (depending on whether you're a D2L client or a D2L partner).
I'm trying to use the FedEx API to track packages. I can authenticate to their test server successfully (using my user credentials, account number, and meter number). However, I receive the same unhelpful response for most tracking numbers that I use in my requests; both test tracking numbers (like 999999999999) and real tracking numbers (that work well on the FedEx website) return the following:
Error Code 9040.
No information for the following shipments has been received by our system yet. Please try again or contact Customer Service at 1.800.Go.FedEx(R) 800.463.3339.
The only requests that fetch a different response are the clearly invalid ones, like "test", which returns:
Error Code 5508.
Invalid tracking number.
I tried SOAP requests using their wsdl (TrackService_v5) as well as manual non-SOAP HTTP POST requests, but their responses are exactly the same in both cases. Is something wrong on their side, or am I doing something wrong?
It seems that FedEx has disabled any test tracking numbers, in the past 999999999999 would work just fine, but now that doesn't even work. To the best of my knowledge, the only way to resolve this is to move to production. Which IMHO is bad because you have to test the tracking part of your application until you move to production.
999999999999 worked for me, but I think I am already in production environment.
