How to cancel a transaction between microservices?

Question

we have an architecture microservicewhere for the most part each is microserviceindependent. But for some inherited reasons, a situation arises when we need to call another microservicefrom another.

for example: the following method is part Legal Service

@Autowired
public ServiceManager UserServiceManager;

public void updateUserLegalData(){

    //do db update of Legal info for the user

   userServiveManager.setAcceptedLegal(true);


}

There are two db transactions. one updates the legalService db and the other updates the UserService db. NOTE. userService is microservicerunning on a separate virtual machine.

we see situations in which the db legal service is updated, but the call to the userService function fails ( Internal server error). therefore, this leaves the application in an inconsistent state. How can we fix this in the recommended way?

thanks
