You can also send Avro, ORC or Feather files.\n\n#### \ud83d\udd01 Reuse from Other Flows\nYou can **reuse this flow** by calling the webhook from another n8n workflow using an **HTTP Request** node. \nMake sure to send the file as **form-data** with the field name `file`.\n\n#### \ud83d\udd0d What This Flow Does:\n- Receives the uploaded file via webhook (`file`)\n- Sends it to `https:\/\/api.parquetreader.com\/parquet` as `multipart\/form-data` (field name: `file`)\n- Receives parsed data, schema, and metadata\n"
