+## 4. Sending a Text Message (v2.x.x Payload Schema)
+In Evolution API v2, the `POST /message/sendText/<instanceName>` endpoint expects a simplified body structure compared to v1.
+- **Method**: `POST`
+- **URL**: `https://<evolution_url>/message/sendText/<instanceName>`
+- **Headers**:
+  - `apikey`: `<global_api_key>`
+  - `Content-Type`: `application/json`
+- **Body**:
+```json
+{
+  "number": "5585981145217",
+  "text": "Your message here",
+  "delay": 1200
+}
+```
+*Note: Do not use the legacy `textMessage` or `options` wrappers (like `{ options: { delay: 1200 }, textMessage: { text: "..." } }`), as these will return a `400 Bad Request` in v2.*
