Future methods in Salesforce can accept primitive data types as parameters.
Primitive data types like Integer, String, Boolean, etc. can be passed as parameters to Future methods.
Non-primitive data types like custom objects or collections cannot be passed as parameters to Future methods.

Use the @future annotation before the method declaration to indicate that the method will run asynchronously in the future.
Pass the subject parameters to the @future method as arguments when calling the method.
Ensure that the subject parameters are serializable to be passed to future methods.
