API User are a special type of user accounts.
To create an API user, navigate to the members' settings using the sidebar. You will find these under the group "Administration" and the item "Members".
Use the tab bar in the members panel and click on the item "API Users". This will take you to the API Users section, which lists all API users, if any are available.
To create a new API user, click on the button "Add API User". You will find this button at the top right of the panel after clicking on "API Users" in the tab bar.
Your should now see the following dialog:
This section defines what the access token may do within the workspace. In other words, all non-Device-specific things, such as administration or creating actions in the Rule Engine.
Simply select the things you need for the token. A typical use case is when you need a token for the administration of your workspace, but not for individual devices.
The Options are identical to those you device when inviting a new member into your workspace. If you want to read more about the available options and what they do, read:
When you create an API user, you can select during the definition which device the token is allowed to access and how this access is staggered.
Use the search field to enter the name of the respective Device, select it and then use the checkboxes to select the rights for the respective Device.
