  • Filters (list) –

    The filters.

    • payment-option - The payment option ( NoUpfront | PartialUpfront | AllUpfront).

    • state - The state of the reservation ( payment-pending | payment-failed | active | retired).

For example, to find all resources that have a tag with the key Owner and the value TeamA, specify tag:Owner for the filter name and TeamA for the filter value.

    • tag-key - The key of a tag assigned to the resource. Use this filter to find all resources assigned a tag with a specific key, regardless of the tag value.

    • (dict) –

      A filter name and value pair that is used to return a more specific list of results from a describe operation. Filters can be used to match a set of resources by specific criteria, such as tags, attributes, or IDs.

      If you specify multiple filters, the filters are joined with an AND, and the request returns only results that match all of the specified filters.

      • Name (string) –

        The name of the filter. Filter names are case-sensitive.

      • Values (list) –

        The filter values. Filter values are case-sensitive. If you specify multiple values for a filter, the values are joined with an OR, and the request returns all results that match any of the specified values.

        • (string) –

  • HostReservationIdSet (list) –

    The host reservation IDs.

    • (string) –

  • MaxResults (integer) – The maximum number of results to return for the request in a single page. The remaining results can be seen by sending another request with the returned nextToken value. This value can be between 5 and 500. If maxResults is given a larger value than 500, you receive an error.

  • NextToken (string) – The token to use to retrieve the next page of results.
