Handling versioned resources

Some of our resources (e.g., Questionnaire and PlanDefinition) are versioned. When you retrieve a versioned resource by id, you'll always get the latest version. If you want to get a specific version, you can append the id with a | and the version you want to retrieve. Make sure you URL-encode the | using %7C.

Summary of System-wide Interactions
  • Supports the transactioninteraction described as follows:

    We currently support batch requests for all our supported resources. Please note that for batch requests there should not be any dependencies between actions in the request. Every action will be handled as a single standalone action.

    For transaction requests we currently only support posting a set of QuestionnaireResponses.
