Amit's answer tells you how to get your AWS_ACCESS_KEY_ID
, but the Your Security Credentials page won't reveal your AWS_SECRET_ACCESS_KEY
. As this blog points out:
Secret access keys are, as the name implies, secrets, like your
password. Just as AWS doesn’t reveal your password back to you if you
forgot it (you’d have to set a new password), the new security
credentials page does not allowing retrieval of a secret access key
after its initial creation. You should securely store your secret
access keys as a security best practice, but you can always generate
new access keys at any time.
So if you don't remember your AWS_SECRET_ACCESS_KEY
, the blog goes on to tell how to create a new one:
- Create a new access key:
- "Download the .csv key file, which contains the access key ID and secret access key.":
As for your other questions:
- I'm not sure about
MERCHANT_ID
and MARKETPLACE_ID
.
- I believe your sandbox question was addressed by Amit's point that you can play with AWS for a year without paying.
