An example of use case is where you want to have different collections for each month in a year.

You can start by creating your own collection!

{% content-ref url="collection/create-collection" %}
[create-collection](https://docs.leanx.io/api-docs/cloud-payment/collection/create-collection)
{% endcontent-ref %}
