# POST Relations

{% hint style="info" %}
 The ***relation*** element is used to create a relation between two sections of your MBurger project. For example, you can use it to link an article to an author, a picture to a point of interest, a video to an event, etc
{% endhint %}

In this example we want to create a section with only one element of type *relation* called `author-relation`. 

The relation field is populated with 2 sections ID: `SECTION1_ID` and `SECTION2_ID`.

```http
POST /api/blocks/<SECTION_ID>/sections HTTP/1.1
Accept: application/json
X-MBurger-Token: <TOKEN>
X-MBurger-Version: <VERSION>
Content-Type: application/x-www-form-urlencoded; charset=utf-8

author-relation[0]=<SECTION1_ID>&author-relation[1]=<SECTION2_ID>
```

> curl

```bash
curl -X "POST" "/api/blocks/<SECTION_ID>/sections" \
     -H 'Accept: application/json' \
     -H 'X-MBurger-Token: <TOKEN>' \
     -H 'X-MBurger-Version: <VERSION>' \
     -H 'Content-Type: application/x-www-form-urlencoded; charset=utf-8' \
     
     --data-urlencode "relation[0]=<SECTION1_ID>&relation[1]=<SECTION2_ID>"
```
