You can also send Avro, ORC or Feather files.\n\n#### 🔁 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#### 🔍 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"
