When you are setting up Identity and Access Management for Amazon DynamoDB and writing a permissions policy that you can attach to an IAM identity
(identity-based policies), you can use the list of Actions,
resources, and condition keys for Amazon DynamoDB in the
IAM User Guide as a reference. The page lists each
DynamoDB API operation, the corresponding actions for which you can grant
permissions to perform the action, and the AWS resource for which you can grant the
permissions. You specify the actions in the policy's Action field, and you
specify the resource value in the policy's Resource field.
You can use AWS-wide condition keys in your DynamoDB policies to express conditions. For a complete list of AWS-wide keys, see the IAM JSON policy elements reference in the IAM User Guide.
In addition to the AWS-wide condition keys, DynamoDB has its own specific keys that you can use in conditions. For more information, see Using IAM policy conditions for fine-grained access control.
