Authorization Extension 500kb Storage Limit Error

Last Updated: Sep 10, 2025

Overview

This article explains the reason and how to mitigate the below warning message while using Authorization Extension :
Warning You've almost reached the storage limit of 500 KB.

Cause

The extension uses Webtask Storage by default, and the customer is limited to 500 KB of data.

If they reach out near the above values, they are bound to get the "Warning: You've almost reached the storage limit of 500 KB."

Solution

The Authorization Extension has a hard limit of 500KB of data when using Webtask Storage. It is not meant to be used with large datasets.

This can be mitigated by using Amazon S3 as the storage provider instead of Webtask Storage.

Before changing the storage type to S3, all the rules, groups, and permissions in the extension would need to be exported.
After it is changed to S3, it would be required to import the exported JSON from Webtask Storage.

Note: This means there will be some downtime, and it is highly recommended to test on a dev tenant first to understand what will occur and how long it will take.
