Generic S3 connection

To access your data from a storage service that is compatible with the Amazon S3 API, create a connection asset for it.

Create a Generic S3 connection

To create the connection asset, you need these connection details:

  • Endpoint URL: The endpoint URL to access to S3
  • Bucket (optional): The name of the bucket that contains the files
  • Region (optional): S3 region. Specify a region that matches the regional endpoint.
  • Access key: The access key (username) that authorizes access to S3
  • Secret key: The password associated with the Access key ID that authorizes access to S3
  • The SSL certificate of the trusted host. The certificate is required when the host certificate is not signed by a known certificate authority.

  • Disable chunked encoding: Select if the storage does not support chunked encoding.

  • Enable global bucket access: Consult the documentation for your S3 data source for whether to select this property.
