# Read and write data

After we've completed setting up the object classes and their properties , we are ready to start reading and writing data in the format we just specified. More specifically, we'll create instances of the Prescription class in the Medable cloud.

The following examples use HTTP. This is most applicable for web development. You might issue these HTTP requests using a tool like Fetch or Ajax. If you're doing iOS or Android development, we wrote SDK's that make it easier for you to interact with these endpoints.

## Create

Creating prescriptions is a simple matter of a `POST` request to the object route.

{% tabs %}
{% tab title="Request" %}

```
POST https://api.dev.medable.com/{{your_org_name}}/v2/c_prescriptions
```

{% endtab %}

{% tab title="Body" %}

```javascript
{
    "c_rx":"Doxycycline 100mg tab. Take one PO bid.",
    "c_dispense": 60,
    "c_refills": 3,
    "c_date":"2016-07-01",
    "c_patient":"575f58281d0c03a53ccc3ac6",
    "c_provider":"5771495a1d0c03a53ce83f1a"
}
```

{% endtab %}

{% tab title="Response" %}

```javascript
{
    "_id": "577c883c6f3035ee08357dfa",
    "access": 7,
    "c_date": "2016-07-01",
    "c_dispense": 60,
    "c_patient": {
        "_id": "575f58281d0c03a53ccc3ac6",
        "object": "account",
        "path": "/accounts/575f58281d0c03a53ccc3ac6"
    },
    "c_provider": {
        "_id": "5771495a1d0c03a53ce83f1a",
        "object": "account",
        "path": "/accounts/5771495a1d0c03a53ce83f1a"
    },
    "c_refills": 3,
    "c_rx": "Doxycycline 100mg tab. Take one PO bid.",
    "created": "2016-07-06T04:25:32.558Z",
    "creator": {
        "_id": "575f58281d0c03a53ccc3ac6",
        "object": "account",
        "path": "/accounts/575f58281d0c03a53ccc3ac6"
    },
    "favorite": false,
    "object": "c_prescription",
    "owner": {
        "_id": "575f58281d0c03a53ccc3ac6",
        "object": "account",
        "path": "/accounts/575f58281d0c03a53ccc3ac6"
    },
    "shared": false
}
```

{% endtab %}
{% endtabs %}

Following this process using the WAPI would look like this:

{% hint style="info" %}
Change the account IDs for*`c_patient` and `c_provider`* to match those in your org.
{% endhint %}

## Get Many

To get that prescription we just created back, we can simply do a `GET` request.

{% tabs %}
{% tab title="Request" %}

```
GET https://api.dev.medable.com/{{your_org_name}}/v2/c_prescriptions
```

{% endtab %}

{% tab title="Response" %}

```javascript
{
    "data": [
        {
            "_id": "577c883c6f3035ee08357dfa",
            "access": 7,
            "c_date": "2016-07-01",
            "c_dispense": 60,

                "path": "/accounts/5771495a1d0c03a53ce83f1a"
            },
            "c_refills": 3,

                "path": "/accounts/575f58281d0c03a53ccc3ac6"
            },
            "shared": false
        }
    ],
    "hasMore": false,
    "object": "list"
}
```

{% endtab %}
{% endtabs %}
