# Filter a list of delivery reports with Node.js

In this tutorial, we will show you how to filter a list of delivery reports using a query parameter.

In the Name a batch tutorial, we showed how to set a value for `client_reference`. Now we'll search for delivery reports containing that value.

## Before you start

You must have:

- 
- [Node.js](https://nodejs.org/en/) and a familiarity with how to create a new app.
- Completed the [Name a batch](/docs/sms/tutorials/node/name-group) tutorial and submitted a `client_reference` value.


What's covered?
- Setting up a Sinch application in Node.js
- Getting a filtered delivery report based on query values set when sending a message.


Goal
At the end of this tutorial, you will have queried a list of delivery reports to find a value set in `client_reference`.

Let's do this.

## Set up your application

1. Once your free Sinch account is setup and you have a virtual number, create
a new folder for your app.
2. Then start up a node app with npm.

```shell
npm init
```
3. Accept the defaults for the application.
4. Add the fetch package with npm to generate the necessary dependencies.

```shell
npm install node-fetch
```


Note:
The node fetch package requires us to use node modules. We'll use `.mjs` files instead of `.js` files.

Next we'll use the `/delivery_reports` endpoint to get a filtered list of reports that contain the value you previously entered for `client_reference`.

## Create a file

Copy and paste the "Filtered delivery report" code into a new file called `deliveryReport.mjs`.

Filter a list of delivery reports
import fetch from 'node-fetch';

async function run() {
  const servicePlanId = 'YOUR_service_plan_id';
  const resp = await fetch(
    `https://us.sms.api.sinch.com/xms/v1/${servicePlanId}/delivery_reports`,
    {
      method: 'GET',
      headers: {
        Authorization: 'Bearer YOUR_API_token'
      },
      query: JSON.stringify({
        client_reference: 'YOUR_value_previously_set'
      })
    }
  );

  const data = await resp.text();
  console.log(data);
}

run();


### Fill in your parameters

1. Assign your values to the following parameters:


| Parameter | Your value |
|  --- | --- |
| `YOUR_service_plan_id` | The service plan ID found on your [Sinch Build Dashboard](https://dashboard.sinch.com/sms/api/rest). SMS > APIs > REST configuration |
| `YOUR_API_token` | The API token found on your [Sinch Build Dashboard](https://dashboard.sinch.com/sms/api/rest). SMS > APIs > REST configuration > Click Show to reveal your API token. |
| `client_reference` | Include the reference you entered in the previous step. Example: `client_reference: "Positive responses to X78695125856AB"`. |


Note:
Since this is a GET request, we'll search based on query parameters rather a body.

1. Save the file.


## Run the code

1. Run the following command in your terminal/command prompt to create a group:



```shell
node deliveryReport.mjs
```

### Successful response

The response should only include the batch that matches the value you entered. Notice the given name of the batch shows under `client_reference`.


```javascript
{
  "count": 1,
  "page": 0,
  "page_size": 1,
  "delivery_reports": [
    {
      "applied_originator": "string",
      "at": "2022-08-24T14:15:22Z",
      "batch_id": "XXXXX6621VXXXXX19Z8PMXXXXX",
      "client_reference": "YOUR_ID_or_name_shows_here",
      "code": 0,
      "encoding": "GSM",
      "number_of_message_parts": 1,
      "operator": "35000",
      "operator_status_at": "2022-08-24T14:15:22Z",
      "recipient": "15551231234",
      "status": "Delivered",
      "type": "recipient_delivery_report_sms"
    }
  ]
}
```

Filtered results. Bam!
