This endpoint replaces a data model with the contents defined in a code representation. You can programmatically update the data model's structure, metadata, and contents. This creates a new version of the data model, which is accessible from the Sigma UI.

For more information on managing data models via the Sigma API, see Manage data models as code. For more information on using this endpoint, including an end-to-end example, see Update a data model from a code representation.

Usage notes

• To perform this operation, you must use API credentials owned by a user assigned the Admin account type.
• Retrieve a representation of an existing data model by calling the /v2/dataModels/{dataModelId}/spec endpoint.
• To create a new data model from code, use the /v2/dataModels/spec endpoint.
• The endpoint only supports updates to the pages array and its contents. Additional fields are not required and are ignored in the request body.
• Partial updates are not supported. You must provide the entire representation of the data model in the request body.
• The default format of the representation is JSON. To use YAML, add the header Content-Type: application/yaml.

Usage scenarios

• Automation: If you want to update several data models across one or more organizations, or in response to external events, you can use this endpoint to programmatically update the data models.
• Integration: Using this endpoint, you can update data models based on external data sources or integrate Sigma with other tools and platforms.
• Version control: Developers can use this endpoint to programmatically manage, update, and version control data models between several organizations or tenants.
• Agentic workflows: Agents can use these endpoints to directly manage data model contents in code.
