Customers can find access to newer service features through the client interface. They provide a higher-level abstraction than the raw, low-level calls made by service clients. To use resources, you invoke the resource method of a Session and pass in a service name:. Every resource instance has a number of attributes and methods. These can conceptually be split up into identifiers, attributes, actions, references, sub-resources, and collections. Each of these is described in further detail below and in the following section.

Whether or not to verify SSL certificates. By default SSL certificates are verified. You can provide the following values:. Get a list of available services that can be loaded as resource clients via Session. Get a list of available services that can be loaded as low-level clients via Session. Return the botocore.

A session in Boto3 encapsulates the configuration state and credentials, allowing developers to create service clients and resources. Customers can find access to newer service features through the client interface. The regex used to validate this parameter is a string of characters consisting of upper- and lower-case alphanumeric characters with no spaces. Profiles represent logical groups of configuration. Session if none is provided , and then get the appropriate client from the session. The credentials that GetSessionToken returns are based on permissions associated with the IAM user whose credentials were used to call the operation. Attributes may incur a load action when first accessed. It will handle in-memory caching as well as refreshing credentials, as needed.

The first option for providing credentials to Boto3 is passing them as parameters when creating clients:. If they have already been loaded, this will return the cached credentials. Non-credential configuration includes items such as which region to use or which addressing style to use for Amazon S3. The list of regions returned by this method are regions that are explicitly known by the client to exist and is not comprehensive. Sub-resources, when instantiated, share identifiers with their parent.
