This operation allows a patient to choose to participate in the Shared Digital Health Record service via HNZ assisted channels. This operation should only be used by HNZ channels. 
Scenarios where this operation might be used include: 
* A patient has opted in to the Shared Digital Health Record service by contacting Health NZ via appropriate digital or assisted channels.
* A patient chooses not to participate in the Shared Digital Health Record service and informs Health NZ of this choice via appropriate digital or assisted channels.
 
For example payloads that might be used with this operation see: 
* [Parameters resource for total non-participation](./Parameters-ParametersHNZParticipateOptOut.md) : This example shows how to indicate that a patient does not wish to participate in the Shared Digital Health Record service (has opted out).
* [Parameters resource for participation](./Parameters-ParametersHNZParticipateOptIn.md) : This example shows how to indicate that a patient wishes to participate in the Shared Digital Health Record service.
 
To make a request to this operation the API Consumer must POST a `Parameters` payload to the operation URL (e.g. `POST https://api.sdhr.digital.health.nz/s2s/$hnz-participate`). 
The operation is idempotent, meaning that multiple requests with the same parameters will have the same effect as a single request. The operation is expected to be called by a Health NZ channel system on behalf of the patient, and the patient must be identified by their NHI. The operation will return an OperationOutcome resource indicating the result of the operation.
