What does QPS mean in Foursquare PlaceAPI? - foursquare

・What does QPS mean on this page ? ( https://developer.foursquare.com/docs/places-api/getting-started/#choose-your-account-tier )
・How many requests can I make in one second?
I think that I can make a maximum of 2 requests per second to endpoints for the Personal Tier Accounts,
but no error occured when I tried to make more than 2 requests per second to endpoints.

Azure - Throttle API based on Number of calls not by who called it

I have an API endpoint that I want to throttle using my API gateway in Azure, but it seems like throttling is always based on someone's IP address, in turn restricting a single user from only being able to call so many times per X seconds/minutes. I want to throttle solely by the number of request per second. I don't care who calls it, it just can't exceed 100 requests per second.
So if 101 different people (with different IP addresses) all call the API at the same time, it will work for the first 100 people, but the 101th person will receive an error message saying something like "Too many requests, try again later"
Is this something that is even possible? How would I go about handling that?
Thanks!

How to handle multiple API Requests

I am working with the Google Admin SDK to create Google Groups for my organization. I can't add members to the group when creating the group, ideally, when I create a new group I'd like to add roughly 60 members. In addition, the ability to add members after the group is created in bulk (a batch request) was deprecated August 2020. Right now, after I create a group I need to make a web request to the API to add each member of the group individually (which will be about 60 members).
I am using node.js and express, is there a good way to handle 60 web requests to an api? I don't know how taxing this will be on my server. If anyone has any resources to share where I can learn about the impact this would have on a nodejs server that would be great.
Fortunately, these groups aren't created often, maybe 15 a month.
One idea I have is to offload the work to something like a cloud function so my node server makes one request to the cloud function, then the cloud function makes all the additional requests to add members to the Group. I'm not 100% sure if this is necessary and I'm curious on other approaches.
Limits and Quotas
Note that adding group members may take 10 minutes to propagate.
The rate limit for the Directory API is 3000 queries per 100 seconds per IP address. This works out to around 30 per second. 60 requests is not a large amount of requests, but if you try to send them all in a few milliseconds the system may extrapolate the rate and deem it over the limit, I wouldn't think so, though probably best to test it on your end with your system and connection etc.
Exponential Backoff
If you do need to make many requests this is the method Google recommends. It involves repeating the request if it fails and then exponentially increasing the amount of time to wait until it reaches 16 seconds. You can always implement a longer wait to retry. Its only 60 requests after all.
Batch Requests
The previously mentioned methods should work no issue for you, since there are only 60 requests to make, it won't put any "stress" on the system as such. That said, the most performant way to handle many requests to the Directory API is to use a batch request. This allows you to bundle up all your member requests into one large batch, of up to 1000 calls. This will also give you a nice cushion in case you need to increase your requests in future!
EDIT - I am sorry, I missed that you mentioned that Batching is deprecated. Only global batching is deprecated. If you send a batch request to a specific API, batching will still be supported. What you can no longer do is send a single batch request to different APIs, like Directory and Sheets in one.

What is the limit for requests to Bitfinex via Sockets?

According to the documentation there a limitation for REST API to Bitfinex:
If an IP address exceeds 90 requests per minute to the REST APIs, the requesting IP address will be blocked for 10-60 seconds and the JSON response {"error": "ERR_RATE_LIMIT"} will be returned. Please note the exact logic and handling for such DDoS defenses may change over time to further improve reliability.
For users who need high-frequency connections, please switch to the WebSockets APIs.
But what is the limit for order count via Socket API (v2) using NodeJS?
After some experiments, I found that request limit is 500 orders per 10 mins, but after a minute or 2 of the ban, you can post 500 requests more.

Instagram API calls limit

Dear Instagram developers team,
Our team is currently in the design phase of a connector to Instagram API for our application.
We bumped into a few questions related to the Instagram API limits.
Would you consider the following scenario as a bad practice?
use all 60 per hour calls for an endpoint until connector receives a 429 response code form the Instagram API
when the first 429 response is received the connector stops calling the Instagram API for 5 minutes, then try again
If the response was successful, continue from step #1, if not - increase 'sleeping time' by 5 minutes each attempt until the call is
successful and then continue from step #1
How many calls that return 429 code our connector can make in an hour
so its behavior would not be considered spammy? Can we make lets say
20 such calls in a row? The question raised because of the very last
sentence on the limits page.
You may also receive responses with an HTTP response code of 400 (Bad Request) if we detect spammy behavior by a person using your
app. These errors are unrelated to rate limiting.
Per hour limit means that at the beginning of an hour the entire limit is
reset or it means that once an API call is made, the available limit will be increased by one after one hour? The second scenario means that if I made 30 calls in one minute and then another 30 after half an hour, when one hour plus one minute passes from the first call only 30 calls will be available.
Is there a way to increase limits for POST or DELETE calls?
Thank you

How to handle the API call rate limit for Docusign in nodejs

How to handle API call rate limit for Docusign in nodejs?I am getting error like "The maximum number of hourly API invocations has been exceeded ".
So, you hit your QPH (queries per hour) limit, right?
Well, there are two things you can do to minize that:
Throttling
Caching
Throttling
When an application has a query limit per period of time, throttling is often a common strategy used.
Throttling revolves around distributing your requests over a period of time. So for example, if you have a 500 limit of requests per hour, you can throttle your application to do 250 requests in the first 30 minutes, and 250 after.
This way you avoid hitting the limit. If you have more requests, then you save them for the next hour.
Caching
Throttling is good because it gives you control over time. But sometimes, requests are similar, so similar in fact that you can just save the answer and use it for later.
Caching is also often used together with throttling, by saving the answers from old requests in your system, and re-using them, you effectively loose the need to make requests against the API, and you gain the ability to answer more user requests (provided you cached them before).
Sum up
There is no silver bullet to solve your problem. There is no simple line of code to do that. Instead, you have two methods that used together will minimize your problem and perhaps even eliminate it altogether if used correctly.
