Logic App: Rosettanet: Custom PIP code : P21

Question

Hi,

I have Logic App integration where I need to send Rosettanet encoded messages to a HTTP URL.

I folowed this guide and implemented most of it.

https://learn.microsoft.com/en-us/azure/logic-apps/logic-apps-enterprise-integration-rosettanet

I need to pass PIP code: P21 which is not available in the Integration account: Agreement :PIP list .

Can somebody guide me as to how to send custom PIP codes to the outgoing messages to HTTP URL?
