There is no `Map\u003cString, String\u003e` that you can pass. \r\n\r\nYou need to be able to pass a `Map\u003cString, String[]\u003e` or a similar multi-valued map. \r\n\r\nAlso, are you including key/value pairs in the url in the verification? If so, it would be good to clearly state that in the docs. If not, that would be a useful service to provide. \r\n\r\n","author":{"url":"https://github.com/cayhorstmann","@type":"Person","name":"cayhorstmann"},"datePublished":"2017-09-17T15:56:50.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/33/basiclti-util-java/issues/33"}
