## Description
This repository holds the files of the openIMIS Backend FHIR R4 API reference module. 
It is dedicated to be deployed as a module of [openimis-be_py](https://github.com/openimis/openimis-be_py).

The module is mapping objects between openIMIS and FHIR R4 representation, 
and allows external applications to use HL7 FHIR R4 standardised communication protocol 
when interacting with openIMIS.

## Documentation
The documentation for this module can be found at [openIMIS Wiki page](https://openimis.atlassian.net/wiki/spaces/OP/pages/1233649676/openIMIS+FHIR+R4+Overview+Page).

## Implementation setup
This module is published on Python Package Index as [openimis-be-api-fhir_r4](https://pypi.org/project/openimis-be-api-fhir_r4).

The FHIR R4 API will be available after the module is deployed on [openimis-be_py](https://github.com/openimis/openimis-be_py). 
Check the [openimis-be_py](https://github.com/openimis/openimis-be_py) 's readme file on how to activate the module 
(add the 'api_fhir_r4' module to [openimis.json](https://github.com/openimis/openimis-be_py/blob/master/openimis.json)) 
and start the openIMIS backend.

## Example of usage
To fetch information about all openIMIS Insurees (as FHIR R4 Patients), send a  **GET** request on:
```bash
http://127.0.0.1:8000/api_fhir_r4/Patient/
```
`127.0.0.1:8000` is the server address (if run on your local host).

## Subscriptions

FHIR API R4 module allows users to define subscriptions and receive notifications when new resources are created or 
updated. Currently, supported resources are:
- Patient
- Organisation (only of `bus` or HealthFacility type)
- Invoice (All Bill and Invoice types defined in `invoiceMapping.py`)

To use the subscription feature a user is required to have related subscription permissions and read permission for subscribed 
resource. To create a subscription the following payload should be sent to `/Subscription/` endpoint:
```JSON
{
    "status": "active",
    "end": "2030-01-01T00:00:00Z",
    "reason": "Invoice",
    "criteria": "Invoice?resourceType=policy",
    "channel": {
        "type": "rest-hook",
        "endpoint": "http://example.com/path",
        "header": [
            "{\"example\": \"1234\"}"
        ]
    }
}
```

Explanation of the payload:
- `status` - required to be `"active"`
- `end` - subscription expiration time (required to have datetime information, `Z` for UTC)
- `reason` - required to match subscribed resource name
- `criteria` - allows to filter resources that should be included in a notification (should match GET arguments format). 
  - To subscribe all resources of a given name, leave the same as `reason`
  - To subscribe all resources of a given type, include `resourceType` argument and specify a type. To subscribe multiple types of a given resource (but not all), create multiple subscriptions
  - You can specify additional filtering arguments after that. Currently, the format should match queryset filter keyword arguments of the underlying IMIS model
- `channel` - specify the target for notifications
  - `type` - currently the only supported type is `rest-hook`
  - `endpoint` - url to send notifications to (should allow POST method)
  - `header` - serialized json string specifying additional headers to be included in POST request, beside the standard HTTP headers (i.e. `Authentication` header with bearer token should be `"{\"Authentication\": \"bearer abcdef0123456789\"}"`). To not include any headers leave as `"{}"`.
