S3 Dynamic Account
Overview
You can use this account type to connect Binary Snaps with data sources that use an S3 account.
Expression-enabled authentication fields, such as Username, Password, and Client Secret, support Secrets Management, a SnapLogic add-on that allows you to store endpoint credentials in a third-party secrets manager, such as AWS Secrets Manager, Azure Key Vault, or HashiCorp Vault. During validation and execution, pipelines obtain the credentials directly from the secrets manager. Learn more: Configure endpoint accounts to use secrets.
Prerequisites
The s3:ListAllMyBuckets permission is required to successfully validate an S3 account. Refer to the Account Permissions section below for additional permissions required for the target resources based on the task to be performed.

| Server-side encryption | Checkbox | The type of encryption to use for the objects stored in S3. For Snaps that
write objects to S3, this field defines how the objects will be encrypted. For Snaps
that read objects from S3, this field is not required. Default status: Deselected |
| KMS Encryption type | Dropdown list | The AWS Key Management Service key used to encrypt S3 objects. It can be the
key ID or ARN. The available options are:
Note:
For Snaps that write objects to S3, this is required for encryption types Server-Side encryption with AWS KMS-Managed Keys and Client-Side encryption with AWS KMS-Managed Keys. For Server-Side encryption, the key must be in the same region as the S3 bucket. For Client-Side encryption, a key from any region can be used by using the key ARN value. If a key ID is used for Client-Side encryption, it defaults to the us-east-1 region. For Snaps that read objects from S3, this field is not required. Default value: None. Example: Server-Side KMS Encryption |
| KMS key | String/Expression | The AWS Key Management Service key used to encrypt S3 objects. It can be the key ID or ARN. For Snaps that write objects to S3, this is required for encryption types Server-Side encryption with AWS KMS-Managed Keys and Client-Side encryption with AWS KMS-Managed Keys. For Server-Side encryption, the key must be in the same region as the S3 bucket. For Client-Side encryption, a key from any region can be used by using the key ARN value. If a key ID is used for Client-Side encryption, it defaults to the us-east-1 region. For Snaps that read objects from S3, this field is not required. Default value: N/A Example: cvcv866kALm920 |
| KMS region | String/Expression/ Suggestion | The AWS region where the KMS key is located. Default value: None. Example: us-east-1 |

IAM role defined in AWS. On selecting this checkbox, the cross account IAM role is
assumed with the maximum session duration defined for the IAM role. Warning: This checkbox is deselected by default. The default maximum session
duration for an IAM role is one hour; however, you can define a custom duration
between 1-12 hours. Learn how to increase the IAM role maximum session
duration limit. We recommend that you select this checkbox if the maximum session duration of the IAM role is greater than an hour. Default status: Deselected |
