The thing.list command is used to find and return a list of things.

Initial TR50 Request with useSearch and iterator

The following example shows a request using useSearch and iterator parameter:

  "cmd": {
    "command": "thing.list",
    "params": {
      "useSearch": true,
      "iterator": "new",
      "limit": "50"

TR50 Response gets the iterator value

When the initial request is made, the parameter iterator should be assigned new. The returned result will then include an additional parameter of iterator containing a temporary unique value related to the initial query made. Example response for the above request:

  "cmd": {
    "success": true,
    "params": {
      "count": 100,
       "fields": [
	{list of field keys} 
	"result": [ 
	{list of result objects} 

TR50 Request with iterator value

This value should be passed on to the iterator parameter for the subsequent requests to iterate through the result set until the entire result set has been returned. A subsequent request after the initial response is shown below:

  "cmd": {
    "command": "thing.list",
    "params": {
      "useSearch": true,
      "limit": "50"

When there is no more data to iterate through you will get the following response:

  "cmd": {
    "success": false,
    "errorMessages": [
	  "Search has reached end of results." 
	"errorCodes": [ 

TR50 Request without iterator

  "cmd": {
    "command": "thing.list",
    "params": {
      "show": [
      "offset": 0,
      "limit": 10,
      "sort": "+name",
      "tags": ["tag1", "tag2"],
      "keys": ["thingkey1", "thingkey2"],
      "hasLoc": true

Request Parameters

Name Type Required Description
show Array An array of field names of the data columns to return.
useSearch Boolean   When useSearch is set to true, it will improve the performance of the operation.
In some cases there is a delay between making changes and when they will be visible to the search database, this delay is typically less than 5 seconds. As such, if you perform an update call, and subsequently call a list, you may not see the results of your operation.
iterator String   iterator is used in conjunction with the useSearch to iterate through the returned results. Initial request should be given the value new. Further requests should be given the value got in from the response. For more information, see the example below at the end of this section with the iterator and useSearch.
offset Integer The starting list offset, used for pagination. Defaults to 0, if not specified.
limit Integer Limits the number of results returned. The maximum limit you can set is 2000. Defaults to 2000.
showCount Boolean   By default, it is set to true. If set to false, the response will not include the count. Setting it to false will improve the response time but you will not know the total size of the result set.
sort String sort is an optional parameter that defines the sort order of the result set. It allows to arrange the list in either ascending(+) or descending(-) order. It is possible to sort thing.list in the following categories:id, name, key, defId, iccid, esn, meid, imei, imsi, msisdn, defName, defKey, lastSeen, loc.updated,, loc.lng, createdOn, updatedOn, apiCounts.daily, apiCounts.monthToDate,, firmware.currentVersion, firmware.targetVersion, firmware.state, varBillingPlanCode, and varVasPackageCode
tags Array If specified, the command will only return things that have all tags in this parameter.
keys Array If specified, the command will only return things that have the keys specified in this parameter.
hasLoc Boolean Only return things that have a location. Defaults to false.
hideFields Boolean If set to true, the response will not include the fields in the response parameters.
boundTo String The ID of a thing. When this is specified, the command will only return things that are bound to the thing identified by the boundTo parameter.

TR50 Response

If the command is sent successfully a success message and the thing is returned. Otherwise, an error and error message will be returned.
