Javascript / Typescript Seam API Library & CLI

Control locks, lights and other internet of things devices with Seam's simple API.

• Library Usage
• Receiving Webhooks

Usage

This package contains both a library and a CLI tool.

CLI Usage

Install with yarn global add seamapi or npm install -g seamapi.

Then:

export SEAM_API_KEY=<your api key> # you can also pass this as an argument to the CLI

seam workspaces list

Library Usage

Install with yarn add seamapi or npm install seamapi -s.

Then:

// Replace with
// const Seam = require("seamapi")
// if not using ES6 modules and/or TypeScript.
import Seam from "seamapi";

// Seam will automatically use the SEAM_API_KEY environment variable if you
// don't provide an apiKey to `new Seam()`
const seam = new Seam();

const myLock = await seam.locks.get({ name: "My Lock" });
const myLockId = myLock.device_id
await seam.locks.lockDoor(myLockId);

console.log(await seam.locks.list())
/*
[
  {
    device_id: '1815b031-e531-432a-9ae6-b3f2cfb77cab',
    device_type: 'smartthings_lock',
    capabilities_supported: [ 'access_code', 'lock' ],
    properties: {
      locked: true,
      online: true,
      name: 'My Lock'
    },
    connected_account_id: '1696fff5-b791-4e30-b039-d8110c78231c',
    workspace_id: '2ff17969-b283-426f-9e8f-045323615eee',
    created_at: '2022-02-25T08:47:56.486Z'
  }
]
*/

await seam.accessCodes.create({
  name: "Some Access Code",
  code: "1234",
  device_id: someLockId,
});

console.log(await seam.accessCodes.list({ device_id: myLockId }))
/*
[
  {
    access_code_id: '6a556ffe-3253-4c31-804e-2c0a32d9015f',

  }
]

Receiving Webhooks

Although you don't need to use this package when receiving webhooks, we strongly recommend that you do. Using the included helper class will verify payloads (preventing malicious requests) and return a well-typed event.

SeamWebhook is a thin wrapper around the Webhook class from the Svix library.

Example for Express:

// Replace with
// const {SeamWebhook} = require("seamapi")
// if not using ES6 modules and/or TypeScript.
import {SeamWebhook} from "seamapi";

import bodyParser from "body-parser";

// Get this from the Seam dashboard
const secret = "sample-secret";

app.post('/webhook', bodyParser.raw({type: 'application/json'}), (req, res) => {
    const payload = req.body;
    const headers = req.headers;

    const wh = new SeamWebhook(secret);
    let msg;
    try {
        msg = wh.verify(payload, headers);
    } catch (err) {
        res.status(400).json({});
    }

    // Do something with the message...

    res.json({});
});

For examples using other frameworks, see the Svix docs.
