I'm working with the REST API in the Workflows domain, and can't figure out the $filter syntax for the life of me. I've tried many different things I can think of, and aways receive a 400 Bad Request error.

Example:

<Error>

  <Message>

    The query specified in the URI is not valid. Syntax error at position 15 in 'WorkflowTypeId=15'.

  </Message>

</Error>

Would love some insight on filter! Thanks.
