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/templates', {
  method: 'POST',
  headers: {
    Authorization: `Bearer ${process.env.SIMPLESMS_API_KEY}`,
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    "name": "Example",
    "body": "Hi {{first_name}}, your order shipped."
  }),
});

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/templates",
    method="POST",
    headers={
        "Authorization": f"Bearer {os.environ['SIMPLESMS_API_KEY']}",
        "Content-Type": "application/json",
    },
    data=json.dumps({
        "name": "Example",
        "body": "Hi {{first_name}}, your order shipped."
    }).encode(),
)
with urllib.request.urlopen(req) as res:
    data = json.load(res)
