Calling Method

For details, see Calling APIs.

URI

GET /v2/{project_id}/design/workspaces

**Table 1** Path Parameters
Parameter	Mandatory	Type	Description
project_id	Yes	String	Project ID. For details about how to obtain the project ID, see Project ID and Account ID.

**Table 2** Query Parameters
Parameter	Mandatory	Type	Description
workspace_type	No	String	Defines the enumeration of model workspace types. Options: THIRD_NF: relational modeling DIMENSION: dimensional modeling
limit	No	Integer	Number of records to be queried on each page, that is, Y records to be queried. The default value is 50, and the value range is [1,100].
offset	No	Integer	Start coordinate of the query, that is, the number of skipped data records. The value can only be 0 or an integer multiple of limit. If the value does not meet the requirement, the value is rounded down. The default value is 0.
dw_type	No	String	Data Connection Type

Request Parameters

**Table 3** Request header parameters
Parameter	Mandatory	Type	Description
X-Auth-Token	Yes	String	IAM token, which is obtained by calling the IAM API for obtaining a user token (value of X-Subject-Token in the response header). This field is mandatory for authentication using tokens.
workspace	Yes	String	Workspace ID. For details about how to obtain the workspace ID, see Instance ID and Workspace ID.
X-Project-Id	No	String	Project ID. For details about how to obtain the project ID, see Project ID and Account ID. This parameter is mandatory for API requests that use AK/SK authentication in multi-project scenarios.
Content-Type	No	String	Default value: application/json;charset=UTF-8 This parameter is optional. If the body is available, this parameter is mandatory. If the body is unavailable, you do not need to set this parameter or verify it.
