        This API is currently provided as a preview. Be aware of the following:


        - There might be unannounced breaking changes.

        - Any breaking changes to preview APIs won''t produce a new [API version](https://www.canva.dev/docs/connect/versions/).

        - Public integrations that use preview APIs will not pass the review process, and can''t be made available to all Canva users.


        </Warning>


        Starts a new [asynchronous job](https://www.canva.dev/docs/connect/api-requests-responses/#asynchronous-job-endpoints) to merge design pages by applying page operations (such as insert, move, or delete) to produce a new design or modify an existing one.


        When the job completes successfully, the job result includes metadata for the created or updated design.


        <Note>


        At this stage, only a single operation per request is supported by default, and passing multiple operations will fail. Contact Canva to enable multi-operation mode for your integration.


        </Note>


        <Note>


        For more information on the workflow for using asynchronous jobs, see [API requests and responses](https://www.canva.dev/docs/connect/api-requests-responses/#asynchronous-job-endpoints). You can check the status and get the results of jobs created with this API using the [Get design merge job API](https://www.canva.dev/docs/connect/api-reference/merges/get-design-merge-job/).
