REST Services - Transaction Rollback
Hi
I have a scenario where my pega flow makes three REST calls (C1, C2 and C3) sequentially to three different external systems to complete a business transaction. All these are POST operations and makes some changes in their respective systems. If C3 fails, I want changes occurred within C1 and C2 should be rolled back. Is there a standard design approach for this? Please advise.
