# Dynamic Flows

> Any dynamic Flow needs an endpoint configured to manage data exchanges between screens.

# Dynamic Flows

## Endpoint

Any `Flow` that is of dynamic type must have an `endpoint` configured during its creation so it can perform exchanges of data between screens. In addition to data exchange, the `endpoint` is also responsible for managing which will be the next screen of the flow.

<Warning>
  The `endpoint` must always be active and responding. If the `endpoint` experiences issues, the `Flow` may suffer throttling by WhatsApp. Learn more in the section on [Endpoint Health / Throttle](#endpoint-health--throttle).
</Warning>

## Webhook

The webhook of the number that sent the `Flow` will be called only after the `Flow` is filled out and sent by the user on a screen that has the `terminal: true` property.

Example of webhook to be filled in after sending by the user:

```json theme={null}
{
  "contacts": [
    {
      "profile": {
        "name": "Felipe Carvalho"
      },
      "wa_id": "5511999999999"
    }
  ],
  "messages": [
    {
      "context": {
        "from": "5511988888888",
        "id": "wamid.HBgMNTU0Mzk2NDE2NTkwFQIAERgSRTc2QkUxMzk4MzEyMDM1OEU1AA=="
      },
      "from": "5511999999999",
      "id": "wamid.HBgMNTU0Mzk2NDE2NTkwFQIAEhgUM0E4Njg5RkE1NzVGNjA4Mzg0NjEA",
      "timestamp": "1721069262",
      "type": "interactive",
      "interactive": {
        "type": "nfm_reply",
        "nfm_reply": {
          "response_json": "{\"flow_token\":\"flow-token\",\"source\":\"0\",\"lastName\":\"Carvalho\",\"email\":\"felipe.carv@gmail.com\",\"firstName\":\"Felipe\"}",
          "body": "Sent",
          "name": "flow"
        }
      }
    }
  ]
}
```

<Info>
  This webhook belongs to one of our `Flows` examples. You can access the example `Flow` this webhook belongs to at [Flow Samples](/en/positus/flows/samples).

## Endpoint Health / Throttle

Flows with unstable endpoints may be throttled by WhatsApp. When the `endpoint` experiences failures or slow responses, WhatsApp may limit the number of allowed requests, affecting the Flow's availability to users. Monitor your endpoint health regularly to avoid these throttles.
