**How to create rows in a Botpress table via the API**

- **Endpoint:** \`POST /v1/tables/{table}/rows\`【4】
- **Headers required:**
- \`Authorization: Bearer <your-token>\`
- \`x-bot-id: <your-bot-id>\`
- \`Content-Type: application/json\`
- **Request body (JSON):** \`{ "rows": [ { "name": "Alice", "age": 30 }, { "name": "Bob", "age": 25 } ], "waitComputed": true }\`

**Quick checklist**
1. Use the POST endpoint above.  
2. Include the three authentication headers.  
3. Provide a \`rows\` array that matches your table schema.  
4. Optionally set \`waitComputed\` to \`true\`.  
5. For easier integration, you can use the official Botpress TypeScript client【12】.

The response returns the created rows with their IDs, timestamps, and any warnings or errors【4】.
