Android Question In App Billing - manager.RequestPayment - DeveloperPayload

Hi everyone,

I was wondering about the DeveloperPayload string variable in manager.RequestPayment method. It is written in the B4X object browser this: "DeveloperPayload: A string that will be tied to the purchase". This is not clear enough for me. What I mean is does this DeveloperPayload bind to the to the on-line Purchases database in Google Play and I can get in the report from Play Store or is it just for internal app usage.

Any expert's knowledge sharing is highly appreciated.

Thanks in advance,
Nikolaos Hatzistelios
