Automate audio post-production workflows with the Auphonic API

Steps

1. Authenticate using an API key: include the header 'Authorization: Bearer YOUR_API_KEY' on all requests — the API also supports HTTP Basic Auth and OAuth 2.0, but API key authentication is the recommended approach for automated workflows
2. Create a production by POSTing to 'https://auphonic.com/api/productions.json' with a JSON body specifying at minimum 'preset' (UUID of a saved preset) or inline 'algorithms' and 'output_files' arrays; presets bundle your standard settings for reuse
3. Upload your audio file to the production via POST to 'https://auphonic.com/api/production/{uuid}/upload.json' using multipart/form-data with the file attached as 'input_file'
4. Start processing by POSTing to 'https://auphonic.com/api/production/{uuid}/start.json' — Auphonic queues the job and processes it asynchronously
5. Poll production status via GET 'https://auphonic.com/api/production/{uuid}.json' and check the 'status_string' field — values progress through 'queued', 'processing', and end at 'done' or 'error'; alternatively configure a webhook URL in the production to receive a POST callback on completion
6. Retrieve output file URLs from the completed production's 'output_files' array and download or forward them to your hosting or delivery system
