Frequently Asked Questions

How is ARTIK Cloud different from other IoT cloud offerings?
Interoperability is one of our key differentiators compared to other cloud services. ARTIK Cloud provides an ecosystem where device manufacturers, application developers, and service providers can discover each other and build sophisticated solutions together without integration pain across vendors or vertical markets.
How do you secure the data in ARTIK Cloud?
We require secure communication protocols (TLS or DTLS) between ARTIK Cloud and a client. The payload and access token are encrypted at the transportation layer. We also support secure device registration for cases where data is especially sensitive (e.g., medical data).
I have a physical IoT device bought on market. How can I connect it to ARTIK Cloud, given that I cannot put a device ID and access token into that device?
Check if the device is listed on our Works With page. Each listed device has been verified to work and contains specific instructions on how to connect it to ARTIK Cloud. For example, for SmartThings, Pebble, and Samsung Gear S2 devices, you can install their corresponding apps to connect them to ARTIK Cloud.

If you are a developer and the device uses its own third-party cloud, you can build a Cloud Connector to allow ARTIK Cloud to receive data from and send commands to the Cloud Connector, treating it as another device.

You can also build a proxy between a physical device and ARTIK Cloud. The proxy could be a device-onboarding mobile app or a program running on a computer. The proxy communicates to the device locally, for example via Bluetooth. Design the login flow in the proxy to obtain a user token to communicate to ARTIK Cloud (for example, an Android app onboarding Polar H7 heart rate sensor). Or put the device ID and access token into the proxy, such as with the Kevo smart lock.
What communication protocols are supported between devices and ARTIK Cloud?
ARTIK Cloud offers a number of protocols for your devices to communicate: REST, WebSocket, MQTT, and CoAP. ARTIK Cloud also supports building Cloud Connectors for devices that use their own third-party cloud. ARTIK Cloud will treat the Cloud Connector as a device.
Do ARTIK Cloud message APIs support retrieving a large number of messages?
Yes. We recommend using the Export API to create an export request for historical messages from up to 30 days. Data can be exported in JSON and CSV formats.
What is the maximum number of events per second and bytes per second that ARTIK Cloud can consume from a single device?
This corresponds to our current rate limits.

Using the REST API: 100/min, 100,000/day
Using WebSockets or MQTT: 1000/min, 100,000/day

The maximum message size is 1,024 bytes. If necessary, this can be increased if you are using a paid pricing plan.
I developed a cool app and I want to store data in ARTIK Cloud, but it's not a device. Can I still use ARTIK Cloud?
YES! ARTIK Cloud defines as "device" any source of data. It can be an actual device, such as a Samsung Gear Fit, or a service that wants to store your data to make it available to you and other services.
OK, I developed a super-awesome app, and I want to use ARTIK Cloud to store values and allow my users to share their data with other apps. Do I need to get certified? What do I do to get started with ARTIK Cloud?
It's very simple. First, you need to learn about the Manifest. Once you have prepared a Manifest, go to the Developer Dashboard, create a new device type, upload its Manifest and wait for it to be approved by our team. Once your Manifest is approved, you can start integrating your app. Feel free to grab one of our SDKs. Once your device type is approved, you can immediately "publish" it and any user will be able to connect this device to ARTIK Cloud.
My device type has not been approved. How can I test my application?
Unfortunately, you will have to wait for us to approve your Manifest. But don't worry, we are actively reviewing Manifest submissions and it should not take too long.
Is there a standard for units such as the metric system or the Imperial system?
Everyone and everything is welcome in ARTIK Cloud. When you submit a new Manifest for a (new) device type, we will review it and recommend changes. You are welcome to send data in the format and unit that suits you best, but in order to make data consistent we will from time to time recommend changes to your Manifest. This will make your app, service or device an active member of the ARTIK Cloud ecosystem.
Is there, or will there be, any facility allowing for data set reduction on ARTIK Cloud (e.g., MapReduce), either on-demand against historical data or applied to a live stream that is generating another stream to be stored?
Not at this time. We will notify our community if our plans change.
How does ARTIK Cloud handle data outages due to loss of device-to-ARTIK-Cloud connectivity?
Devices are responsible of keeping the connection to ARTIK Cloud active. If there is an outage, it will be the device’s responsibility to re-establish the connection.
Is there, or will there be, a pull model where ARTIK Cloud will pull data from a device?
This is not planned at this time.
Is there any notion of a heartbeat between ARTIK Cloud and a device for monitoring?
When using WebSockets, ARTIK Cloud will send a heartbeat. The device is supposed to close and reopen the connection if no heartbeat is received. No heartbeat is supported when using REST, as the device is supposed to initiate the communication and it is the device's responsibility to make it work.
Can I search for a message with a specific key/value pair?
ARTIK Cloud allows you to query messages based on a start and end time, or querying the last N messages. A search functionality to extract messages with specific values is currently not implemented.
Can I upload images to ARTIK Cloud?
ARTIK Cloud is designed to store and manage data that can be shared and reused by multiple applications and services. Some of the data might also be converted from one unit to another. At this time binary data such as images and videos don't meet our goals and require a lot of physical space. We recommend that you use a storage system that is optimized for this type of data.
I successfully created a new device type and successfully posted a message of this type of devices. Later on I retrieve the message from ARTIK Cloud using the message ID. However, in the message, I do not see the data fields that I added when posting that message to ARTIK Cloud?
After you post a message to ARTIK Cloud, you will get a message ID back. However, this does not mean that your message has been successfully parsed or stored in ARTIK Cloud. The raw message received by ARTIK Cloud is normalized when passing through ARTIK Cloud. The normalization uses the Manifest of the device type you created. The normalization may fail to identify the fields of data in your message. For example, there is a typo in the field name of your message. We suggest you to capture the raw data you send to ARTIK Cloud and follow Validate your Manifest to test your data. Your unit test should test if any field of the normalized data is NULL and also compare the values of the raw and normalized data.
