Node.js

The Node.js SDK does not wrap this endpoint yet; call it with fetch.

javascript
const res = await fetch('https://api.joinsimplesms.com/v1/scheduled_messages/job_1759400000000a1B2c3D4e5', {
  method: 'GET',
  headers: {
    Authorization: `Bearer ${process.env.SIMPLESMS_API_KEY}`,
  },
});

if (!res.ok) throw new Error((await res.json()).error.message);
const data = await res.json();

Python

The Python SDK does not wrap this endpoint yet; call it over HTTP.

python
import json, os, urllib.request

req = urllib.request.Request(
    "https://api.joinsimplesms.com/v1/scheduled_messages/job_1759400000000a1B2c3D4e5",
    method="GET",
    headers={
        "Authorization": f"Bearer {os.environ['SIMPLESMS_API_KEY']}",
    },
)
with urllib.request.urlopen(req) as res:
    data = json.load(res)
