The rest of the SDK seems to work with how we we're using it.","author":{"url":"https://github.com/localpath","@type":"Person","name":"localpath"},"datePublished":"2022-04-05T17:00:34.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/175/sample-code-php/issues/175"}
