Endpoint Handling

This setting is only visible if you select Enable above.

Define whether to select the callback from a list of callbacks or to manually enter a callback:

• Select from a list of endpoints (default): Select an endpoint from a list of available endpoints.
• Manually enter a URL: Manually enter an endpoint URL below.
  You need to enter a manual callback if you access PRTG via a different DNS name. For example, if you access PRTG via myPRTG.example.com but the actual DNS name of the PRTG core server is myPRTG.internal.example.com, you need to enter a manual callback.

Available Callback URLs

This setting is only visible if you select Enable and select Select from a list of endpoints (default) above.

This list shows the available callbacks of this PRTG instance. Select the callbacks that your users use to connect to PRTG.

If you define an HTTPS endpoint in this field, you need to configure the HTTPS endpoint as a valid redirection URI in your SSO provider's settings.

External Callback URL

This setting is only visible if you select Enable and select Manually enter a URL above.

If you access PRTG via a different DNS name, define the HTTPS endpoint.

This is necessary if the DNS name that you configured under Setup | System Administration | User Interface does not appear in the Available Callback URLs list. For example, if you access PRTG via myPRTG.example.com but the actual DNS name of the PRTG core server is myPRTG.internal.example.com, then enter myPRTG.example.com. Also make sure to add the port used by PRTG for HTTPS and the endpoint in the URL, for example: myPRTG.example.com:PORT/cb.

If you define an HTTPS endpoint in this field, you need to configure the HTTPS endpoint as a valid redirection URI in your SSO provider's settings.

Available Callback URLs (for reference)

This setting is only visible if you select Enable and select Manually enter a URL above.

This list shows the available callbacks URLs of this PRTG instance for reference purposes.
