So, putting this all together, the URI would look something like this:

The compatible vehicle property name and corresponding value are delimited with a colon (:), such as filter=Year:2018, and multiple compatible vehicle property name/value pairs are delimited with a comma (,).

Note: Commas are used as delimiters between filter values. If a value includes a comma (e.g., BodyStyle:AWD B9 8W5,C8WD) you must include a backslash (\) immediately before the comma to prevent it from being evaluated as a delimiter.

As with all query parameter values, the filter parameters must be URL encoded. For more information about encoding request parameters, refer to URL encoding query parameter values.

For example, to retrieve all vehicle trims for a 2022 Audi A4:The resulting comma-separated filter query parameter is:
filter=Year:2022,Make:Audi,Model:A4,BodyStyle:AWD B9 8W5\,8WD

The following sample shows the same filter but with URL encoding for the blank spaces.
GET https://api.ebay.com/commerce/
