# Create One Data Lake Pipeline **POST /api/atlas/v1.0/groups/{groupId}/pipelines** Creates one Data Lake Pipeline. [Data Lake Pipelines are deprecated. Please see Data Lake Deprecation Guide.](https://dochub.mongodb.org/core/data-lake-deprecation) ## Servers - https://cloud.mongodb.com: https://cloud.mongodb.com () ## Authentication methods - Service accounts - Digest auth ## Parameters #### Path parameters - **groupId** (string) Unique 24-hexadecimal digit string that identifies your project. Use the [/groups](#tag/Projects/operation/listProjects) endpoint to retrieve all projects to which the authenticated user has access. **NOTE**: Groups and projects are synonymous terms. Your group id is the same as your project id. For existing groups, your group/project id remains the same. The resource and corresponding endpoints use the term groups. #### Query parameters - **envelope** (boolean) Flag that indicates whether Application wraps the response in an `envelope` JSON object. Some API clients cannot access the HTTP response headers or status code. To remediate this, set envelope=true in the query. Endpoints that return a list of results use the results object as an envelope. Application adds the status parameter to the response body. ## Body parameters Content-type: application/json Creates one Data Lake Pipeline. - **datasetRetentionPolicy** (object) Dataset Retention Policy for a Scheduled Data Lake Pipeline. - **name** (string) Name of this Data Lake Pipeline. - **sink** (object) - **source** (object) - **transformations** (array[object]) Fields to be excluded for this Data Lake Pipeline. ## Responses ### 200: OK #### Body Parameters: application/json (object) - **_id** (string) Unique 24-hexadecimal digit string that identifies the Data Lake Pipeline. - **createdDate** (string(date-time)) Timestamp that indicates when the Data Lake Pipeline was created.
