## Steps

The following steps assume that you successfully logged in into OpenHIM and the CHT instances.
See the [OpenHIM guide]({{< ref "building/guides/interoperability/openhim" >}}) for instructions to set up a local development instance of OpenHIM.

1. Create an **Endpoint** and an **Organization**

1. **HTTP Request** - Use Postman to create an `Endpoint` Resource in the Mediator. You can view the API documentation for creating an `Endpoint` [here](#endpoint-resource). Once you send the request, the Mediator will return a JSON response containing the `id` of the newly created endpoint.

1. **CHT** - Log in to the CHT platform using the credentials for the `chw` user (if the `chw` user does not already exist, you can [create one]({{< ref "building/contact-management/contact-and-users-1#4-create-the-chw-user" >}}).
1. **CHT** - Navigate to the `People` tab in the CHT dashboard. From there, select a Facility where you want to create a new `Person`. Click on the `New Person` button and fill in the required details for the Person. Make sure to select `Patient` as the `Person`'s role for this flow.
1. **CHT** - Once you have created the new `Person`, you need to retrieve their unique identifier from the browser's URL. You can do this by copying the alphanumeric string that appears after `person/` in the URL. Keep this identifier safe as you will need it for the next steps.
1. **OpenHIM Admin Console** - To verify that the `Patient` creation was successful, navigate to the `Transaction Log` in the OpenHIM Admin Console. You should see two successful API calls recorded in the log, one to `/mediator/patient/` and one to `/fhir/Patient/`.

This project uses OpenHIM as the middleware component with [Mediators](http://openhim.org/docs/configuration/mediators/) to do the conversion. [Outbound Push](https://docs.communityhealthtoolkit.org/apps/reference/app-settings/outbound/) is configured to make a request to the middleware when relevant documents are created or modified in the CHT. A Mediator then creates a FHIR resource which is then routed to OpenHIM. OpenHIM routes the resource to any other configured systems.

Conversely, to bring data into the CHT, OpenHIM is configured to route the updated resource to the Mediator, which then calls the relevant [CHT APIs](https://docs.communityhealthtoolkit.org/apps/reference/api/) to update the document in the CHT database. This will then be replicated to users’ devices as per usual.

### Prerequisites

- `docker`
- `Postman` or similar tool for API testing. This will play the role of the `Requesting System` from the sequence diagram above.

### CHT configuration with Docker

The following steps apply when running CHT via the Docker setup provided in this repository:

1. CHT can be accessed via `http://localhost:5988`, and the credentials are `medic`/`password`.
2. Create a new user in the CHT instance with the username `interop-client` using these [instructions]({{< ref "building/contact-management/contact-and-users-1#4-create-the-chw-user" >}}). For the role you can select `Data entry` and `Analytics` roles. Please note that you can use any username you prefer but you would have to update the config with the new username. You can do that by editing the `cht-config/app_settings.json` file and updating the `username` value in the `outbound` object e.g. on this [line](https://github.com/medic/interoperability/blob/main/cht-config/app_settings.json#L452).
3. Securely save the `interop-client` user's password to the database using the instructions [here]({{< ref "building/reference/api#credentials" >}}). Change the values `mykey` and `my pass` to `openhim1` and your user's password respectively. An example of the curls request is below:

```bash
curl -X PUT -H "Content-Type: text/plain" http://medic:password@localhost:5988/api/v1/credentials/openhim1 -d 'interop-password'
```

### Local setup of CHT Configuration

The following steps apply when running CHT locally in development mode and when making configuration changes locally:

#### CHT Development Environment

1. Set up a local CHT instance using [these instructions]({{< ref "building/local-setup" >}}).
2. Create a new user in the CHT instance with the username `interop-client` using these [instructions]({{< ref "building/contact-management/contact-and-users-1#4-create-the-chw-user" >}}). For the role you can select `Data entry` and `Analytics` roles. Please note that you can use any username you prefer but you would have to update the config with the new username. You can do that by editing the `cht-config/app_settings.json` file and updating the `username` value in the `outbound` object e.g. on this [line](https://github.com/medic/interoperability/blob/main/cht-config/app_settings.json#L452).
3. Securely save the `interop-client` user's password to the database using the instructions [here]({{< ref "building/reference/api#credentials" >}}). Change the values `mykey` and `my pass` to `openhim1` and your user's password respectively. An example of the curls request is below:

```bash
curl -X PUT -H "Content-Type: text/plain" http://medic:password@localhost:5988/api/v1/credentials/openhim1 -d 'interop-password'
```
4. After updating the mediator code or cht configuration, you need to run `./startup.sh up-dev` to upload the changes to docker compose.

#### CHT Configuration

1. Go into the `cht-config` directory by running `cd cht-config`.
1. Run `npm install` to install the dependencies.
1. Create a file named `.env` under `/mediator` folder, copy over the contents of `/mediator/.env.template` and update the `CHT_USERNAME` and `CHT_PASSWORD` values with the admin credentials of your CHT instance.
1. Set up a proxy to your local CHT instance by running using something like [nginx-local-ip](https://github.com/medic/nginx-local-ip) or [ngrok](https://ngrok.com/) and update the `CHT_URL` value in the `.env` file with the new URL.
1. Ensure you have [cht-conf](https://www.npmjs.com/package/cht-conf) installed and run `cht --local` to compile and upload the app settings configuration to your local CHT instance.
1. To verify if the configuration is loaded correctly is to create a `Patient` and to access a URL like `https://*****.my.local-ip.co/#/contacts/patientUUID/report/interop_follow_up`. This should retrieve correctly the follow up form.
1. To verify if the configuration in CouchDB, access `http://localhost:5984/_utils/#database/medic/settings`.

### Shutdown the servers

- To shut-down the containers run `./startup.sh down` to stop the instances.
