    Hello Joby Chacko,

    Thank you for the update, and I’m glad to hear the issue has been resolved.

    The error AADSTS7000215: Invalid client secret provided usually occurs when the application is still using an old or incorrect client secret. After creating a new client secret in the App Registration, it is important to update the client secret value (not the secret ID) in all places where the application uses it, such as:

    • Application configuration files (for example: appsettings.json, web.config, or environment variables)
    • Azure services like App Service, Function Apps, Automation Accounts, etc.
    • Any secure storage like Azure Key Vault, if used

    Also, make sure to restart the application or service after updating the secret so the new value is picked up.

    As you confirmed, updating the secret in both the code and environment variables resolved the issue. This indicates the application was previously using the old secret value.

    If you have any further questions, feel free to reach out.
