post https://api.scale.com/v1/batches/{batchName}/finalize
For "Self Serve" customers only, finalizes a batch with name batchName so its tasks can be worked on.
As of June 2021, all other customers no longer need to finalize batches, batches will already be finalized and ready for tasks to be created in them. Calling this endpoint will do nothing, but still return a 200 success status code.
