# Partial Success for Bulk Operations

## Introduction

Some endpoints allow you to create or modify several entities with a single request. This type of request has a different response structure, and you must know how to read it accordingly to avoid unexpected scenarios.

## HTTP Codes Status

A bulk call will always answer with the status for the main scope of the request and not for each operation. For example:

* An error in authentication, authorization, deserialization, the answer will return a code 4xx
* In any other scenario, the answer will return a code 200 regardless of the individual operations success or fail

## Individual Error

Even when receiving a status code 200, it is important to check the existence and the content of the `errors` array in the response. Example:

<CodeGroup>
  ```json JSON theme={null}
  {
      "data": [
      {
          /* confirmation for all successful operations */
      },...],
      "errors": [/* omitted if no error */
          ... /* list or operations that failed with the assigned error  */
      ],
      "warnings": [/* omitted if no error */
          ... /* list or operations that failed with the assigned error */
      ]
  }
  ```
</CodeGroup>
