Amazon Redshift will no longer support the creation of new Python UDFs starting Patch 198. Existing Python UDFs will continue to function until June 30, 2026. For more information, see the [ blog post ](https://aws.amazon.com/blogs/big-data/amazon-redshift-python-user-defined-functions-will-reach-end-of-support-after-june-30-2026/). 

# Authorizing access to the Amazon Redshift Data API
<a name="data-api-access"></a>

To access the Data API, a user must be authorized. You can authorize a user to access the Data API by adding a managed policy, which is a predefined AWS Identity and Access Management (IAM) policy, to that user. As a best practice, we recommend attaching permissions policies to an IAM role and then assigning it to users and groups as needed. For more information, see [Identity and access management in Amazon Redshift](https://docs.aws.amazon.com/redshift/latest/mgmt/redshift-iam-authentication-access-control.html). To see the permissions allowed and denied by managed policies, see the IAM console ([https://console.aws.amazon.com/iam/](https://console.aws.amazon.com/iam/)).
