API Examples
The Device Controller can be accessed via an API to allow customers to send data to the devices in an automated way without going through the portal.
The Device Controller API description is available in the API Explorer.
Examples
Create Action Request
An action request can include different fields per protocol. Therefore, an example request body is given for every protocol.
UDP
Creating UDP action request for a device with deviceId 123456789012345678
:
curl -X POST "https://api.1nce.com/management-api/v1/integrate/devices/123456789012345678/actions/UDP"
The request body looks like this:
{
"payload": "Data to send to the device",
"payloadType": "STRING",
"port": 3000,
"requestMode": "SEND_NOW"
}
CoAP
Creating CoAP action request for a device with deviceId 123456789012345678
:
curl -X POST "https://api.1nce.com/management-api/v1/integrate/devices/123456789012345678/actions/COAP"
The request body looks like this:
{
"payload": "Data to send to the device",
"payloadType": "STRING",
"port": 3000,
"path": "/example?param1=query_param_example",
"requestType": "POST",
"requestMode": "SEND_NOW"
}
LwM2M
Creating LwM2M action request for a device with deviceId 123456789012345678
:
curl -X POST "https://api.1nce.com/management-api/v1/integrate/devices/123456789012345678/actions/LWM2M"
The request body looks like this:
{
"action": "write",
"resourceAddress": "/3311/0/5850",
"data": "Data to send to the device",
"requestMode": "SEND_WHEN_ACTIVE"
}
Bulk request
Creating LwM2M action request for multiple devices:
curl -X POST "https://api.1nce.com/management-api/v1/integrate/devices/actions/LWM2M"
The request body looks like this:
{
"action": "write",
"resourceAddress": "/3311/0/5850",
"data": "Data to send to the device",
"requestMode": "SEND_WHEN_ACTIVE",
"deviceIds": ["123456789012345678", "123456789012345679", "123456789012345680"]
}
Retry Mechanism
When submitting an action request with SEND_WHEN_ACTIVE
mode, the user can specify the parameter sendAttempts
in
the request body to restrict how many times the device controller can attempt to send the data to the device.
If all attempts fail, then the action request will be permanently marked with the status FAILED
.
The sendAttempts
parameter is optional and, if unspecified, defaults to 1.
The maximum number of allowed retries is 5.
⚠️ Please note that this functionality is NOT supported by the UDP protocol.
Request Body Properties
These are the properties of a request body. It specifies when and which message will be sent to the device.
Property | Data Type | Description | Available for protocol. *Optional |
---|---|---|---|
payload | STRING | Data to send to the device. | UDP, *CoAP |
payloadType | ENUM | Type of the payload. Values: STRING , BASE64 . | UDP, *CoAP |
port | INTEGER | Communication port number of a device. | UDP, CoAP |
requestMode | ENUM | Values: SEND_NOW , SEND_WHEN_ACTIVE (when a device sends a message). Default: SEND_NOW . | *UDP, *CoAP, *LwM2M |
path | STRING | Absolute path to the resource. | CoAP |
requestType | ENUM | Method used to send message. Values: GET , POST , PUT , DELETE , PATCH . | CoAP |
action | ENUM | LwM2M action name. Values: read , write , execute , observe-start , observe-end . | LwM2M |
resourceAddress | STRING | LwM2M OMA object resource address. | LwM2M |
data | STRING | Data to send to the device. | *LwM2M |
sendAttempts | INTEGER | The maximum number of attempts to send data to the device. Default: 1 | *CoAP, *LWM2M |
Note that for LwM2M there's no possibility to provide a data type for the data
property. For LwM2M we support 8 data types: TIME, STRING, BOOLEAN, INTEGER, FLOAT, UNSIGNED_INTEGER, OBJLINK and OPAQUE. The data type depends on the addressed resource. Users should provide the data in a stringified format (base64 encoded string for OPAQUE). In case an invalid data type for a resource is used, an Admin Log will be created.
Response
The API will accept the request with a 202 Accepted
response code and a response body containing two properties: id (string) and message (string). The id can be used to track the status of the request or cancel the request (see examples below). The message property contains a confirmation message about the request created. Example:
{
"id": "trxHeBL0d234fsfds",
"message": "Action read for resource /3/45/22 successfuly scheduled for device 123456789012345678."
}
Get action request(s)
Get action request(s) endpoints are available to track the status of the request and potentially see the response from a device using CoAP/LwM2M. The requestData
property return protocol-specific request data provided when the request was created. For LwM2M the responseData
can contain the following properties if available: code
(response code), payload
(data from the device), for Coap there is also additional field - payloadType
(payload type). The payloadType
is either TEXT
when the response content format is printable, or BASE64
if the content format is not printable or not present at all. In case an error occurs, the field errorMessage
is present in the responseData
.

By using the optional filter query parameters
There are 2 endpoints available that support query parameters and are meant to query action requests by different statuses:
Active action requests are those which have statuses IN_PROGRESS
and SCHEDULED
Archived action requests are those which have statuses CANCELLED
,FAILED
and SUCCEEDED
Getting multiple archived requests with optional filters (query parameters) specified. For example, to get all LwM2M action requests that succeeded for a device with id 123456789012345678::
