The following example shows how to configure a Node Red flow that uses the Indigo Web Server (IWS) API to operate a lamp device. The example is only meant to show how to use a self-signed certificate and public key to enable the flow to connect to the IWS using https instead of http when using the IWS on a local network via 10.0.1.123, 127.0.0.1, or localhost (using the API via the Indigo Reflector Service uses a different CA-approved security certificate and the flow is configured the same as it would be using any API via https).

Using the flow via https requires a few settings. Enter the preferred URL to point at the local IWS address 10.0.1.123, 127.0.0.1, or localhost with the URL:

https://<INDIGO IP ADDRESS>:8176/v2/api/command/

for example,

https://10.0.1.123:8176/v2/api/command/

select TLS, and use bearer authentication along with a valid token key (from your Indigo Account Authorizations).

Then, use key and certificates from local files and point them to the certificate and public key files located in

/Library/Application Support/Perceptive Automation/Indigo 2025.2/Web Assets/cert/
