OAuth 2.0's Client Credential grant type in SAP PO 7.4

Hi all,

I'm working with SAP PO 7.4 and I need to use an API REST with authentication OAuth 2.0's grant type.

Is it possible to use it or SAP PO 7.5 is needed?

Note 2405166 refers to PO 7.5, anyway is it possible to use this kind of authenticaton or do I have to force an upgrade to 7.5?

Thank you

Nicola
