# Retrieve Catalog

The most common flow in the e-learning system begins with users starting their learning journey from the catalog page. To retrieve the catalog page with the available trainings for a specific user or anonymous one, you can use the following API query:

<CodeGroup>
  ```filename GraphQL [expandable] theme={null}
  query getCatalogData {
    getCatalogData(first: 3) {
      edges {
        node {
          cta {
            actionId
            title
            arguments {
              key
              value
            }
            metadata {
              key
              value
            }
          }
          modulesNumber
          activitiesNumber
          training {
            title
            domain {
              name
            }
            image {
              alt
              title
              url
            }
            duration {
              name
            }
            attempt {
              metrics {
                progress
                status
              }
            }
          }
        }
      }
      pageInfo {
        hasNextPage
        startCursor
        endCursor
      }
      totalItems
    }
  }
  ```

With the data retrieved from the example above, you should be able to build the catalog page as shown below.

<img style={{ borderRadius:"0.3rem" }} src="https://mintcdn.com/connect-i/duHonZHPe3F63_yi/images/image-20250506-091047.png?fit=max&auto=format&n=duHonZHPe3F63_yi&q=85&s=f5d1fde7df8bbb93dab71f8bde087e7b" alt="Image 20250506 091047 Pn" width="1846" height="916" data-path="images/image-20250506-091047.png" />

The catalog query can be enhanced with filtering, pagination, and sorting options. Please refer to the dedicated pages for more details.
