This is Step 2 of the Custom Model workflow. You must complete Step 1: Prepare first. See the full workflow guide.
Upload one audio file per request. The task result contains clip info with an id field — collect these as clipIds for the create step. You need at least 6 successful uploads before proceeding to create.
Multiple upload requests can run in parallel with the same sessionId. Each returns its own taskId for independent polling.
