  • app - the name of an external partner
  • MFT profile - the external partner connectivity parameters
  • Additional subscription parameters, as defined in the template


When subscribing to a template in Standalone mode, you are required to set the following fields:

  • Subscription name
  • Partner
  • Client communication profile
  • Additional subscription parameters, as defined in the template

Add a subscription configuration to a template field

Next to each template field there is a   icon with the Add to a subscription configuration tooltip.
