# Sample Use Cases and Flows

This article presents possible use cases and corresponding sample flows that you can support. This can be a helpful jumping off point as you plan your implementation.

## Organize photography projects by theme
You can develop a photo analyzer to categorize related photography projects into collections based on theme.

1. Call [Create Collection](https://dev.wix.com/docs/rest/business-solutions/portfolio/collections/create-collection.md) to create a collection for projects with a shared theme. Save the returned collection ID for a later step. 

2. Analyze your projects and identify those with a shared theme.

3. Use the [Projects API](https://dev.wix.com/docs/rest/business-solutions/portfolio/projects/introduction.md) to add the projects with a shared theme to the collection by assigning the saved collection ID to each project.

4. Call [Get Collection](https://dev.wix.com/docs/rest/business-solutions/portfolio/collections/get-collection.md) to display the collection.

## Keep your data current with collection events
You can use the Collections API to keep up with collection changes by Wix users.

1. Listen for the [Collection Created](https://dev.wix.com/docs/rest/business-solutions/portfolio/collections/collection-created.md), [Collection Updated](https://dev.wix.com/docs/rest/business-solutions/portfolio/collections/collection-updated.md), and [Collection Deleted](https://dev.wix.com/docs/rest/business-solutions/portfolio/collections/collection-deleted.md) events to detect changes made by Wix users.

2. Based on the event type, adjust your data to reflect the latest collections.
