# MPI/CR Test Cases for HL7v2

These test cases are based on the OpenHIE CR tests for HL7v2 transactions, and contain specific hints for SanteMPI.

## Security Configuration

All tests for HL7v2 should ensure they are using either:

* [Node authentication ](/developers/service-apis/hl7v2/hl7-authentication.md#node-authentication-using-x-509-certificates)- Meaning that an X.509 certificate environment has been configured on the MPI. Note that all device configurations should map the certificate to the credential for the device.
* [Msh8 Authentication](/developers/service-apis/hl7v2/hl7-authentication.md#msh-8-authentication) - Meaning that `MSH-8` should carry necessary authentication information to authenticate the sending node.

For more information on how HL7v2 messages are authenticated in SanteDB, please consult the [HL7 Authentication](/developers/service-apis/hl7v2/hl7-authentication.md) wiki article.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.santesuite.org/installation/installation-1/deployment/installing-software/santedb-server/installation-qualification/fhir-interface-validation/mpi-cr-test-cases-for-hl7v2.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
