Click the cogwheel on the top right and select Manage Environments, then click Add.To do so, create an environment and configure the placeholders.
#Postman download zip file how to#
You need to tell Postman how to fill these placeholders and by this, how to connect to your Cumulocity IoT account. Note that the example contains placeholders, in this case a placeholder /alarm/alarms. This shows an example on how to get alarms from Cumulocity IoT. Open that folder and the subfolder Alarms, then click Get collection of alarms. You should see a folder Cumulocity IoT API with the examples. Now, click the Collections tab on the top left of Postman. After starting Postman, you can choose to either create an account or click Take me straight to the app.ĭownload the API examples and import them as a collection into Postman.

If you want to make use of them, download and install Postman. Graphical REST clients such as Postman are a convenient way to explore REST interfaces and the Cumulocity IoT database content.Ĭumulocity IoT provides numerous online API examples. More information on page handling can be found under Rest usage > Query result paging in the Cumulocity IoT OpenAPI Specification. $ curl -u : You will notice that just a subset of the items in the inventory is actually returned, a so-called “page”. If you want to start browsing the Cumulocity IoT APIs, enter on a command line: For experimentation and for understanding Cumulocity IoT’s REST interfaces, it is helpful to use one of the numerous available command line tools or browser extensions.įor example, many operating systems come with pre-installed tools such as the cURL command. Nowadays, most programming environments have particular support for REST-based communication. If you develop applications using Java or C#, check these relevant sections for even more convenient access to Cumulocity IoT’s functionality.įor further information on REST interfaces in general and on integrating devices with REST, refer to the REST section in the Device SDK guide. Sensor library specifies the data model for sensors and controls.Device management library specifies the data model for device management.REST implementation is the reference for all general concepts.Relevant secions in the Cumulocity IoT OpenAPI Specification are in particular: The description is closely linked to the Cumulocity IoT OpenAPI Specification, which describes each interface in detail. With this API description you will learn how to use Cumulocity IoT’s REST interfaces to develop microservice applications on top of the Cumulocity IoT platform. One of the many books introducing REST is RESTful Web Services. It is today the de-facto Internet standard supported by all networked programming environments ranging from very simple devices up to large-scale IT. REST is a very simple and secure protocol based on HTTP(S) and TCP. Regardless whether the communication originates from IoT devices, from web applications or from back-office IT systems, the communication protocol is always REST.
