In V5.5SP3*, we could able to reset/change the API password for any created user which can be used as a service account for calling Saviynt APIs. For the current V23.7, there is no option for changing the API password.
Currently, we couldn't able to authenticate using the Saviynt password in postman, how can we change the API password?
Note: Our environment is integrated with SSO.
ChangePassword API is still supported in 23.7 and the error you are facing might be a permission issue.
Can you please share the error message or snapshot (mask sensitive information) to assist you better on this issue?
