# Default Configurations
Before diving into the ways of setting default configurations there are a few things that need some introduction.
## IDs
In the Template Editor elements that are not an atomic level elements (e.g. a material or a mesh) have IDs. See the area circled in red below.
These IDs are generated automatically but they can also be set/changed by you. Whenever there is a need to use IDs it is always recommended to change them to a human readable format.
This is also the case when you want to control default configurations through the API because these IDs have to be set through the API.
## Example
Here is an example of a code where default configurations of a product is set.
We will only show the link that is used in the configurator and not the complete \*\*iframe \*\*code so that it is easier to read.
```javascript
https://configurator.colormass.com/?apiVersion=2&sceneId=2268¶m(combined%2Fcategory)=id(taps)¶m(combined%2Ftaps%2Ftaps)=id(OMI-133-C-P)¶m(combined%2Ftaps%2Ffinishes%2Ffinishes)=id(polished-black)
```
This might look a bit complicated at first, so lets break it down step by step. You will notice that the URL parts are separated with `&` symbols, and there are two types of elements in the URL above.
```javascript
sceneId = 2268;
```
This is responsible for the viewer where a specific light settings (which you should be familiar with from the previous articles in the documentation) are used and our product is added.
```javascript
param(combined%2Fcategory)=id(taps)
```
These are the ones that set a specific configuration to selected default. You will see a strange character combination: `%2F` . Whenever you see those just think of them as `/` Using slash in the URL has a special meaning so it is recommended to use these special characters instead of the slash. We read the above text inside the `param` as `combined/category=taps`
So to take the above scene as an example you will see that inside this scene the product is called `combined` and the template that is used inside is `Combined (Omika)`.
Let's say we want to set the default category of the above product. To be able to set a specific configuration we have to set the path in the template using the IDs. So in this specific case the path will be `combined/category`.
{% hint style="info" %}
Explanation: the ID of the main product is `combined` and the config group inside has an ID called `category`. See screenshot below.
{% endhint %}
Once you have identified the path to the configuration group and added it to the param part of the URL like so:
```javascript
param(combined%2Fcategory)
```
you will also need to set it to a specific Configuration Variant, which in this case will be Taps, see screenshot below.
and that is how we arrive to the final segment of our URL:
```javascript
param(combined%2Fcategory)=id(taps)
```
