Hi @Mithila Lishan,
Welcome to the Microsoft Q&A Platform! Thank you for asking your question here.
Managing client secrets for high-scale API integrations in Azure API Management (APIM) can indeed present some challenges, especially when compared to open-source solutions where secrets can remain valid indefinitely.
To mitigate that challenge we can implement automated workflows using Azure Key Vault and Azure Functions to handle secret rotation.
Please refer the below link for the documentation on the same.
