How to execute batch webapi requests on power pages?

Hello everyone,

according to information on this page Execute batch operations using the Web API (Microsoft Dataverse) - Power Apps | Microsoft Learn I tried to execute a batch request on power pages but I only get "406 (Not Acceptable)" error message. Could you please check if there is anything wrong with my code? Or how else can I execute batch requests?

The code to execute the api request:

fetch(`/api/data/v9.2/$batch`, {
        method: 'POST',
        headers: {
          'OData-MaxVersion': '4.0',
          'OData-Version': '4.0',
          'Content-Type': `multipart/mixed; boundary="batch_8a23z8"`,
          'Accept': 'application/json',
          'If-None-Match': 'null',
        },
        body: batchdata,
      })
        .then(response => response.json())
        .then(data => {
          console.log('Batch request success:', data);
        })
        .catch(error => {
          console.error('Batch request error:', error);
          // Log the detailed error response if available
            if (error.responseText) {
                console.error("Server response:", error.responseText);
            }
        });

The test value in "batchdata" variable (I tried to type it in as text but it causes error when I update post):

Thank you for your help in advance!

1. Skip $batch in Power Pages
For multiple actions:

Run them one by one with fetch or safeAjax.
Use Power Automate for server-side batch processing.

2. Use safeAjax
Handles CSRF tokens automatically. Example:
webapi.safeAjax({
  type: "POST",
  url: "/_api/accounts",
  contentType: "application/json",
  data: JSON.stringify({ name: "Sample Account" }),
  success: function (res, status, xhr) {
    console.log("entityID: " + xhr.getResponseHeader("entityid"));
  }
});
3. Power Automate For Batch Tasks
Send a list of operations to a flow using Dataverse connectors to bypass portal Web API limits.
