API Slow performance

[Justin Estruch]

Hi,

I am seeing very slow performance with the API over the past few days. Particularly with GET /users lately. Any reason for this?

[Justin Estruch]

Also I am noticing the API is taking 25 seconds to respond after making our first API call. For example, if I call GET /users and then based on the user.id of the user I call GET /assets. The GET /assets call takes 25 seconds to respond while the GET /users call only takes 500ms. Is there some sort of rate limiting/ DDOS prevention going on here?

Hello any update on this?

you're right. See for details: https://github.com/sherpadesk/api/wiki#limits-and-pages

If servers are in High DTU mode (overloaded), we delay group of items requests for 25 seconds and item request for 5 sec.

If servers has normal load, we dont limit requests. You can see it on presence of 

X-Highdtu-Mode:

header. more value is servers more overloaded.

Thank you. But according to the Wiki, API requests are limited to 600 per hour? Is that 600 per authenticated API account? Or is it 600 API calls for the SherpaDesk API globally? 

Because I am nowhere near 600 per hour.

Is there a way to not be affected by the High DTU header as a paying customer?

Thanks,

Justin

Hi,

Thanks for reply. I need to update wiki for High DTU mode.

we limit requests per organization. But there are time periods, when users do a lot of heavy requests.

So we need to protect our servers from DDOS attack. 

When we detect high load on Database, we add High DTU limit and add additional limit for frequent requests.

from 25 seconds. If you detect this header. please do your request rate longer, not every millisecond.

according to our logs. only 6 requests were in high load times. others were done instantly.

Thanks Eugeen,

Is it possible for SherpaDesk to override or whitelist our public IP or organization API key? Reason being, we've created an application that accesses in Real time what assets are assigned to our users. So we need this data to be realtime and not a nightly sync or something along that line.

Thanks,

Justin

yea, this is possible

how many requests and total data size you expect each day?

Thanks Eugene. Do I need to send you my Org API key or my public IP? Also throughout the year we only do a few API calls during the day (maybe 100 per day) then for two weeks a year we will likely do (1000 to 3000 API calls per day). This is when we check in and out our Chromebooks for the district for all our students.

Thanks.

Hi,

I whitelisted your org for now. 

When I optimize API limits logic, I'll notify you to test.

Please keep updated on any problems with API,

Eugene

Hi,

no thanks. I added SBOE org to whitelist. Your limits 600 calls each hour.
