Overview

This article clarifies the size and length limitations of the "conditions.expression.value" parameter in the Create Group Rule API for Okta.

Applies To
  • Okta Administrators
  • Okta Group Rules API
  • Terraform 
Cause

This arises when administrators need to assign a large number of group IDs into the "conditions.expression.value" parameter in the API.

Solution

While Okta has not specifically implemented any limitations for string parameters such as "conditions.expression.value", the technical limit for fixed-string data type, which is approximately 64K characters, applies.
 

For improved performance, limiting the size of the API call is advisable. As a recommended practice, consider using multiple requests with about 100 groups per API call.
