Create custom lists for use in playbooks

A custom list is a collection of values that you can use in a playbook, such as a list of banned countries, or blocked or allowed IP addresses. Custom lists are used to save information in a visual format that can be used to make decisions or track information about playbooks. In your Filter and Decision blocks, compare parameters against all the values in a custom list, rather than having to configure each comparison in the playbook.

See REST Lists in the REST API Reference for for information about how to manage custom lists using the REST API.

Export a custom list for use with third-party products and services

You can use the REST API to export a custom list for use as an external deny list with third-party products and services. For example, you can publish a list of banned IP addresses that can be used in your Palo Alto Networks firewall products.

Perform the following tasks to export a custom list and use it in a third-party product.

1. Review the formatting requirements that your third-party product or service has for custom lists. For example, Palo Alto Networks products may have specific formatting requirements for their dynamic lists. Review these requirements so that the formatting in your custom lists match these formatting requirements of your third-party product or service.
2. Provide a URI to the custom list in using the following format:

   https://username:password@[soar server]/rest/decided_list/[list name]/formatted_content?_output_format=csv

   For example, to provide a URI to the server SOAR_server.example.com, using admin as the user and password as the password, and a custom list named blockdomains:

   https://admin:password@SOAR_server.example.com/rest/decided_list/blockdomains/formatted_content?_output_format=csv
