Calling the REST API directly from Go

package main

import (
  "bytes"
  "encoding/json"
  "fmt"
  "net/http"
)

func main() {
  body, _ := json.Marshal(map[string]any{
    "amount_ars":       5000,
    "destination":      "0000003100010000123456",
    "destination_kind": "CBU",
  })
  req, _ := http.NewRequest("POST", "https://sandbox-api.nuez.app/v1/withdraws", bytes.NewReader(body))
  req.Header.Set("Authorization", "Bearer "+jwt) // from POST /v1/auth/token
  req.Header.Set("Idempotency-Key", "inv-2026-04-001")
  req.Header.Set("Content-Type", "application/json")

  resp, err := http.DefaultClient.Do(req)
  if err != nil {
    panic(err)
  }
  defer resp.Body.Close()
  var result map[string]any
  json.NewDecoder(resp.Body).Decode(&result)
  fmt.Println(result["id"], result["status"])
}
