To check your IAM permissions for S3 PutObject operations, there are several approaches you can take: Using the IAM Policy Simulator The AWS IAM Policy Simulator allows you to test whether you have the required permissions for specific actions. This tool can help identify if your permissions are being explicitly allowed or denied by any policies. Checking Your Current Permissions in AWS Console Try using Console and see if you are getting any permission error. If you receive an "Access Denied" error, it typically means you're missing one or more required permissions.
Remember that AWS uses a combination of different policy types that affect your permissions:
- Identity-based policies
- Resource-based policies
- Permission boundaries
- Service control policies (SCPs)
The final permissions are determined by evaluating all these policy types together, with an explicit deny always overriding any allows.
Hope this helps. Thanks!
