Tipos de Conector:

• HttpReader - Sondear endpoints HTTP (solicitudes GET)
• HttpWriter - Enviar datos a endpoints HTTP (POST, PUT, DELETE)

Lector HTTP

Sondear un endpoint HTTP periódicamente:

{
  "type": "HttpReader",
  "config": {
    "endpoint": "http://api.example.com/data",
    "pollingRate": 5000,
    "method": "GET",
    "headers": {
      "Authorization": "Bearer TU_TOKEN",
      "Accept": "application/json"
    }
  }
}

Escritor HTTP (POST)

Enviar datos vía POST:

{
  "type": "HttpWriter",
  "config": {
    "endpoint": "http://api.example.com/data",
    "method": "POST",
    "headers": {
      "Content-Type": "application/json",
      "Authorization": "Bearer TU_TOKEN"
    }
  }
}

Escritor HTTP (PUT)

Actualizar datos vía PUT:

{
  "type": "HttpWriter",
  "config": {
    "endpoint": "http://api.example.com/data/123",
    "method": "PUT",
    "headers": {
      "Content-Type": "application/json"
    }
  }
}

• timeout: (Opcional) Timeout de solicitud en milisegundos

Encabezados Comunes

{
  "headers": {
