curl -X POST "https://webhook.toolkitapi.io/v1/bins" \
  -H "X-API-Key: YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"name": "my-webhook-test", "ttl_seconds": 3600}'
import httpx

resp = httpx.post(
    "https://webhook.toolkitapi.io/v1/bins",
    headers={"X-API-Key": "YOUR_KEY"},
    json={
        "name": "my-webhook-test",
        "ttl_seconds": 3600,
    },
)
bin_data = resp.json()
print("Catch URL:", bin_data["bin"]["catch_url"])
const resp = await fetch(
  "https://webhook.toolkitapi.io/v1/bins",
  {
    method: "POST",
    headers: {
      "Content-Type": "application/json",
      "X-API-Key": "YOUR_KEY",
    },
    body: JSON.stringify({
      name: "my-webhook-test",
      ttl_seconds: 3600,
    }),
  }
);
const data = await resp.json();
console.log("Catch URL:", data.bin.catch_url);
