How to publish an Extension to Azure FHIR repository?

Question

I am using Azure API for FHIR. I have a Claims payload that requires some additional fields, which I am adding to the extension structure like:

extension: [
    {
        "url": "ROW_ID",
        "valueString": "1"
    },
    {
        "url": "LOB",
        "valueString": "MAPD"
    }
]

To perform a search on ROW_ID, and LOB, I need to publish this extension which I would be using in my SearchParameter.
How and where do I publish the extension ?

Answer 1

To publish an extension, you post the structure definition to your FHIR server. In addition, if you need to search for it you will need to create a custom search parameter and reindex the database.
