# Get stages of a single course sequence

> 
Get stages of a single course sequence.
---
Returns a list of sequence stages (`CourseSequenceStage` objects) of the specified course sequence.

To get the fist stage only, use `limit=1`.

To filter by grade, use `grade={grade}`.

To get the first stage of the specific grade, use `grade={grade}&limit=1`.

    # Authentication


    All endpoints require authentication using the `Authorization: Bearer
    <token>` header.


    The token can be obtained with:


    ```

    curl -X POST
    https://prod-beyond-timeback-api-2-idp.auth.us-east-1.amazoncognito.com/oauth2/token
    \

    -H "Content-Type: application/x-www-form-urlencoded" \

    -d
    "grant_type=client_credentials&client_id=<your-client-id>&client_secret=<your-client-secret>"

    ```


    Use the correct IDP server depending on the environment you're using:


    IDP Server for this environment:

    ```

    https://prod-beyond-timeback-api-2-idp.auth.us-east-1.amazoncognito.com

    ```

    application.


    # Pagination


    Our API uses offset pagination for list endpoints. Paginated responses
    include the following fields:


    - `offset`: Offset for the next page of results

    - `limit`: Number of items per page (default: 100, maximum: 3000)


    **Note:** While the OneRoster specification does not define a maximum limit,
    this implementation enforces a maximum of 3000 items per page to prevent
    abuse and ensure optimal performance.


    Example request:


    ```

    GET /ims/oneroster/rostering/v1p2/users?offset=20&limit=20

    ```


    All listing endpoints support offset pagination.


    # Filtering


    All listing endpoints support filtering using the `filter` query parameter,
    following 1EdTech's filtering specification.


    The filter should be a string with the following format:


    ```

    ?filter=[field][operator][value]

    ```


    Example request:


    ```

    GET /ims/oneroster/rostering/v1p2/users?filter=status='active'

    ```


    Example request with multiple filters:


    ```

    GET /ims/oneroster/rostering/v1p2/users?filter=status='active' AND
    name='John'

    ```


    **Filtering by nested relations is not supported**.


    # Sorting


    All listing endpoints support sorting using the `sort` and `orderBy` query
    parameters, following 1EdTech's sorting specification


    Example request:


    ```

    GET /ims/oneroster/rostering/v1p2/users?sort=lastName&orderBy=asc

    ```


    # Proprietary Extensions


    This implementation includes proprietary extensions that extend beyond the
    official OneRoster 1.2 specification to provide additional functionality.


    ## Search Parameter


    In addition to the standard `filter` parameter, this implementation provides
    a `search` query parameter for simplified free-text searching:


    ```

    GET /ims/oneroster/rostering/v1p2/users?search=john

    ```


    **Purpose**: The `search` parameter enables convenient text-based queries
    across multiple fields simultaneously, whereas the standard `filter`
    parameter requires specifying exact field names and operators:


    ```

    # Search parameter - searches across multiple fields automatically

    GET /ims/oneroster/rostering/v1p2/users?search=john


    # Equivalent using standard filter parameter

    GET /ims/oneroster/rostering/v1p2/users?filter=givenName~'john' OR
    familyName~'john'

    ```


    The `search` parameter performs case-insensitive partial matching across
    predefined fields for each endpoint, providing a more user-friendly querying
    experience.


    ## OneRoster 1.2 Standard Parameters


    The official OneRoster 1.2 specification defines these standard parameters:


    - `limit` - pagination limit

    - `offset` - pagination offset

    - `sort` - field to sort by

    - `orderBy` - sort direction (asc/desc)

    - `filter` - filtering expression

    - `fields` - field selection


    ## Affected Endpoints


    The proprietary `search` parameter is available on the following endpoints:


    **Rostering API**:


    - `GET /ims/oneroster/rostering/v1p2/academicSessions/`

    - `GET /ims/oneroster/rostering/v1p2/classes/`

    - `GET /ims/oneroster/rostering/v1p2/classes/{classSourcedId}/students`

    - `GET /ims/oneroster/rostering/v1p2/classes/{classSourcedId}/teachers`

    - `GET /ims/oneroster/rostering/v1p2/courses/`

    - `GET /ims/oneroster/rostering/v1p2/courses/{courseSourcedId}/classes`

    - `GET /ims/oneroster/rostering/v1p2/demographics/`

    - `GET /ims/oneroster/rostering/v1p2/enrollments/`

    - `GET
    /ims/oneroster/rostering/v1p2/schools/{schoolSourcedId}/classes/{classSourcedId}/students`

    - `GET /ims/oneroster/rostering/v1p2/users/`


    **Gradebook API**:


    - `GET /ims/oneroster/gradebook/v1p2/assessmentLineItems/`

    - `GET /ims/oneroster/gradebook/v1p2/assessmentResults/`

    - `GET
    /ims/oneroster/gradebook/v1p2/classes/{classSourcedId}/students/{studentSourcedId}/results`

    - `GET /ims/oneroster/gradebook/v1p2/results/`


    **Resources API**:


    - `GET /ims/oneroster/resources/v1p2/resources/`


    ## Parameter Usage Guide


    ### Filter Parameter


    The standard `filter` parameter provides precise control over queries using
    these operators:


    - `=` - Exact match

    - `!=` - Not equal

    - `~` - Contains (case-insensitive)

    - `>`, `>=`, `<`, `<=` - Comparison operators

    - `@` - In list (comma-separated values)


    ### Logical Operators


    Combine multiple conditions in filter expressions:


    - `AND` - Both conditions must be true

    - `OR` - Either condition must be true


    ### Usage Examples


    ```bash

    # Simple text search across multiple fields

    GET /users?search=john


    # Equivalent precise filtering

    GET /users?filter=givenName~'john' OR familyName~'john'


    # Complex filtering with multiple conditions

    GET /users?filter=status='active' AND givenName~'john'


    # Advanced filtering with different operators

    GET /users?filter=dateLastModified>'2023-01-01' AND status='active'

    ```


    ## Search Fields by Endpoint


    Different endpoints search across these predefined fields:


    - **Users**: `givenName`, `familyName`, `email`

    - **Courses**: `title`, `courseCode`

    - **Classes**: `title`

    - **Organizations**: `name`


    ## Interoperability Notes


    The `search` parameter is a proprietary extension specific to this
    implementation. Other OneRoster-compliant systems may only support the
    standard `filter` parameter. When building applications that need to work
    with multiple OneRoster providers, consider using the standard filtering
    approach.


    ## Additional Schema Fields


    ### AssessmentLineItem Extensions


    The AssessmentLineItem schema includes two proprietary fields that extend
    curriculum mapping capabilities:


    #### Component Field


    - **Field**: `component`

    - **Type**: Object reference (`{ sourcedId: string }`)

    - **Purpose**: Direct association between assessment line items and course
    components, enabling enhanced curriculum mapping and learning pathway
    tracking.


    #### ComponentResource Field


    - **Field**: `componentResource`

    - **Type**: Object reference (`{ sourcedId: string }`)

    - **Purpose**: Direct association between assessment line items and specific
    learning resources, supporting detailed content-to-assessment relationships
    and adaptive learning features.


    **Example Usage**:


    ```json

    {
      "sourcedId": "assessment-123",
      "title": "Chapter 5 Quiz",
      "component": { "sourcedId": "component-456" },
      "componentResource": { "sourcedId": "resource-789" }
    }

    ```


    ## Affected Endpoints


    ### Schema Extensions Availability
