I imagine this should be a simple question but I cannot find an answer.

I am trying to query using the REST API for one **article** with my custom field **id** of **THIS\_IS\_IT** ;

The issue is I receive an array of every article no matter how I configure the filter object. What am I doing wrong?

```auto
const options = {
   url: `${config.cms.endpoint}collections/get/articles?token=${config.cms.apiKey}`,
   method: 'POST',
   encoding: 'utf-8',
   body: JSON.stringify({
     filter: { published: true, id: 'THIS_IS_IT' },
     sort: { _created: -1 },
   }),
   resolveWithFullResponse: false,
 };

 const articles = await request(options);

```

Thank you so much!

I guess If you’re using **JSON.stringify** , you should add `"Content-type: application/json"` . Otherwise, it will use a default `"application/x-www-form-urlencoded"`

As I understand, you’re filtering by ID and it will return a specific entry. So, `sort` isn’t necessary here.

You can also try this below option

```javascript

${config.cms.endpoint}collections/get/articles?filter[published]=true&filter[id]=THIS_IS_IT&token=${config.cms.apiKey}

```
