Why is my API getting called multiple times?

Duplicate API Requests: Possible Reasons

There can be different scenarios where an API is called multiple times to get the data. For example, When a user taps on a button multiple times before it gets disabled. At times, one API response causes another API request to execute.

What happens if 2 requests are sent at nearly the same time data to the server?

If two requests come in two different network cards AT THE SAME TIME, then one will get priority (lower number on the bus?), and one request will edge forward. A single CPU can only run a single instruction at once. If you have a multi-core, and there is contention between the cores, one will have priority.

How to handle multiple requests at the same time in Java?

You basically need to start shedding requests and packets early. TCP syncookies should be on. Rate limit SYNs, as the forged connections won't retry. Limit the effect of this by supporting connection re-use, HTTP/2 and (if you can) HTTP/3.

How do I stop duplicate post requests?

Using the Idempotency feature is a way of preventing data corruption caused by sending duplicate requests. To send a post request that is "Idempotent safe", simply include an idempotency_key header. The idempotency_key must be unique and should only be used in one request.

How do you handle multi request?

One way you can handle multiple requests is to have multiple physical servers. Each request can be given to a server that is free and it can service it. This approach is highly inefficient as we are adding more servers without effectively using resources of the existing servers.

How to handle 1,000 requests per second?

To handle high traffic, you should setup Load Balancer with multiple node/instances. Better to go with Auto Scaling on Cloud server. It will increase the instances as per high load (number or request) and again decrease the instances when there will be low number of requests. Which is cost effective.

How do servers handle requests from multiple clients?

It handles each request individually, although it may process many requests simultaneously. Each request is broken down into a series of steps that together make up the request-handling process. The status code and reason phrase tell the client how the server handled the request.

How does REST API handle multiple requests at the same time?

If you need to make multiple API requests, you can send these API requests concurrently instead of sending them one by one. Sometimes, we need to make multiple API calls at once. For example, let's say we have an array, and we want to make an API request for each element of that array.

How do I ignore duplicate entries?

Use the INSERT IGNORE command rather than the INSERT command. If a record doesn't duplicate an existing record, then MySQL inserts it as usual. If the record is a duplicate, then the IGNORE keyword tells MySQL to discard it silently without generating an error.

How do I stop duplicate sent emails?

Re: Outlook is sending duplicated mails

In Outlook : File --> Account Settings --> Double Click the Account Name (highlighted yellow in the screen below) --> More Settings --> Tab Sent Items --> Choose option " Do not save copies of sent items". Refer to the screen shot below.

How do I stop my sent emails from being duplicated?

Open the “Prevent to send duplicated emails to recipients with the same address” (“PreventDuplicatesSending” code) system setting and select the [ Default value ] checkbox on the opened page. Click [ Save ].

What triggers an API call?

These calls are made after executing administration operations, such as create, update and delete, for the following Mashery objects: Member, Application, Key and Package Key. In other words, event trigger API calls are made after the data is saved in the Mashery database.

Is there a limit to API calls?

By default, it is set to 100 requests per 100 seconds per user and can be adjusted to a maximum value of 1,000. But the number of requests to the API is restricted to a maximum of 10 requests per second per user.

How do you fix an API problem?

To fix this, check with your API provider to see if there is a testing environment that doesn't utilize caching. Alternatively, double check your API call on a different machine or with a different set of credentials. You can also check your API documentation to see if there's some cache invalidation method available.

How many API calls is too many?

But in most cases our servers will reject API requests from a particular application if the request rate exceeds 30 API requests per minute. In this case the client will get an HTTP error with status code 429 “too many requests”.

What is the difference between server and API?

An API is an Application Programming Interface, which is a way to provide information for other applications (communication among applications). A server is any machine running some process that will execute some service for you.

How to handle 1,000 requests per second?

To handle high traffic, you should setup Load Balancer with multiple node/instances. Better to go with Auto Scaling on Cloud server. It will increase the instances as per high load (number or request) and again decrease the instances when there will be low number of requests. Which is cost effective.

How many requests can my API handle?

In the API Console, there is a similar quota referred to as Requests per 100 seconds per user. By default, it is set to 100 requests per 100 seconds per user and can be adjusted to a maximum value of 1,000. But the number of requests to the API is restricted to a maximum of 10 requests per second per user.
