Batch delete patterns in Rest API

Introduction

Batch delete patterns help remove many items at once using a single request. This saves time and makes your app faster.

You want to delete multiple user accounts at once.

You need to remove many files or records in one go.

You want to clear old data matching certain rules quickly.

You want to reduce the number of requests to the server.

You want to keep your app responsive by deleting in bulk.

Syntax

Rest API

DELETE /resource
{
  "ids": ["id1", "id2", "id3"]
}

OR

DELETE /resource?ids=id1,id2,id3

Batch delete usually uses the HTTP DELETE method.

You can send IDs in the request body or as query parameters, depending on the API design.

Examples

Deletes users with IDs 123, 456, and 789 by sending them in the request body.

Rest API

DELETE /users
{
  "ids": ["123", "456", "789"]
}

Deletes files with IDs abc, def, and ghi by passing IDs in the URL query.

Rest API

DELETE /files?ids=abc,def,ghi

Sample Program

This Python code sends a batch delete request to remove three items by their IDs. It prints success or failure based on the server response.

Rest API

import requests

url = "https://api.example.com/items"

# IDs to delete
ids_to_delete = ["item1", "item2", "item3"]

# Prepare JSON body
payload = {"ids": ids_to_delete}

# Send DELETE request with JSON body
response = requests.delete(url, json=payload)

if response.status_code == 200:
    print("Items deleted successfully")
else:
    print(f"Failed to delete items: {response.status_code}")

Important Notes

Not all APIs support batch delete; check the API docs first.

Some APIs limit how many items you can delete at once.

Always handle errors in case some items cannot be deleted.

Summary

Batch delete removes many items with one request.

Use DELETE method with IDs in body or query.

It saves time and reduces server load.
