Your First Device API Call
5 mins
So what exactly can you do with Jane's devices? Well, that depends on their Capabilities! Let's discuss what those are and then use them.
For example, on a door-lock the
access_codes capability lets you program pin-codes. These codes then let a user unlock the door without keys.Each Capability decomposes into
actions, properties, and events. - Actions — things you can do to it.
- Properties — the current state of the device.
- Events — reports from the device describing state transitions.
Taken as a whole, the capabilities of a device describe its programmatic interface. At Seam, we work as best we can toward standardizing each capability's API across brands. For example, our lock/unlock actions work the same across brands of door locks.
Let's inspect one of Jane's August devices to see its capabilities. Here we can see that her August locks support
lock and access_codes capabilities.Javascript
Python
Ruby
PHP
// 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 inspectDeviceCapabilities = async () => {
const {
devices: [someLock],
} = await seam.locks.list();
console.log(someLock.capabilities_supported);
};
inspectDeviceCapabilities();
/*
[ 'access_code', 'lock' ]
*/
from seamapi import Seam, Device
seam = Seam()
some_lock = seam.locks.list()[0]
# Inspect the Lock
print(some_lock.capabilities_supported)
# ['access_code', 'lock']
require "seamapi"
seam = Seam::Client.new(api_key: "MY_API_KEY")
some_lock = seam.locks.list().first
# Inspect the Lock
puts some_lock.capabilities_supported
# ['access_code', 'lock']
use Seam\SeamClient;
$seam = new SeamClient("YOUR_API_KEY");
$some_lock = $seam->locks->list()[0];
echo json_encode($some_lock->capabilities_supported)
# ["access_code", "lock"]
The
lock capability provides two actions: LOCK and UNLOCK. It also has a locked property to know its current status. Let's use this to toggle its state!

import Seam from "seamapi";

const toggleLock = async () => {
const {

// If the lock is opened, lock it, else unlock it
if (someLock.properties.locked) {
await seam.locks.unlockDoor(someLock.device_id);
} else {
await seam.locks.lockDoor(someLock.device_id);
}
};
toggleLock();
from seamapi import Seam, Device
seam = Seam()
some_lock = seam.locks.list()[0]
# Unlock or lock the door
if some_lock.properties["locked"]:
seam.locks.unlock_door(some_lock)
else:
seam.locks.lock_door(some_lock)
require "seamapi"
seam = Seam::Client.new(api_key: "MY_API_KEY")
some_lock = seam.locks.list().first
# Unlock or lock the door
if some_lock.properties["locked"]
seam.locks.unlock_door(some_lock.device_id)
else
seam.locks.lock_door(some_lock.device_id)
end
use Seam\SeamClient;
$seam = new SeamClient("YOUR_API_KEY");
$some_lock = $seam->locks->list()[0];
if ($some_lock->properties->locked) {
$seam->locks->unlock_door($lock->device_id);
} else {
$seam->locks->lock_door($lock->device_id);
}
The
access_code capability lets you program pin code on a lock. This code can be used to unlock the door without keys. Let's program an access code.
