New request body examples for transactions

Request examples

Updated request/response examples in API Reference for each endpoint

Duplicate validation

Consumers will no longer be able to onboard the same MONIZZE account (duplicates) multiple times to the same wallet. The same MONIZZE account can still be onboard to multiple wallets.
- Note: duplicate validation does only work for MONIZZE accounts added to a wallet after this release. It is suggested to re-onboard any existing MONIZZE accounts.
Duplicate XTRA accounts, with the same IBAN can't be onboard to the same wallet. The same XTRA account can still be onboard to multiple wallets.

WLW ➡️ WSP integration changes

Changed field(s) in Process WLW transaction init request
- sessionId within the session object was always equal to the field transactionId. To be consistent, we have removed the field transactionId, meaning you should rely on sessionId within the session object.
- Removed status field.
Change field Process WLW transaction result request.
- transactionId ➡️ sessionId
Change field in Process WLW events:
- In the data field you have been able to expect a transactionId when receiving transaction events, this field has now changed to sessionId. See example event in WSP Events table.
