Before you can add HTTP devices, you must add a connector to the HTTP server to receive data from the devices via HTTP posts.
Before you begin
What you should know
- The HTTP server is hosted by the Industrial IoT plugin role, and installed when the HTTP Server protocol is selected during the installation process.
- HTTP requests are made with the API key, the HTTP server identifier that is
generated when you create the HTTP connector.
This key must be kept secret to protect your system against malicious users.
- Values that are sent through HTTP requests can be used to raise events, trigger alarms, and so on.
Procedure
-
Under the HTTP connecters list, click Add HTTP
connector (
).
-
In the Add HTTP connector dialog box, do the following:
-
Click Copy to clipboard (
) to
copy the API key.
IMPORTANT: The API key is what identifies your HTTP server and is required by all devices (HTTP clients) to connect to the plugin role (HTTP server). For security reasons, this key is not saved in any registry or database. You cannot access the API key after you close this dialog box. Keep it in a safe place. You will need it every time you add an HTTP device to your system.
