Creating a Java API Session

Question

I am trying to create a Java API, and I simply cannot make sense of the credentials. Years ago, I created an Access key, planning to create an API, but got busy and never used it. Now I am trying to move forward with this and I am having trouble creating the 'config' and 'credentials' files. I think I have created the config file, but I am not 100% sure it is correct. For the credentials file, I have the 'aws_access_key_id' and the 'aws_secret_access_key', which I saved years ago, but I don't know what the 'aws_session_token', how to create it, or how to find it.

When I try to test it, I found online it said to test it to run: aws sts get-caller-identity

Which generates: Error loading SSO Token: Token for MUA-API does not exist (obviously my Instance is 'MUA-API')

... I am completely confused.

Thanque!

Try to run aws sts get-caller-identity with --debug option. You will see more details about the error with debug option. you can generate session token using get-session-token command. https://docs.aws.amazon.com/cli/latest/reference/sts/get-session-token.html
But do you need temporary session token? It seems you have long term credentials.
