List values of Operation Type

Anyone know list values of OperationType:
eg: native_transfer, in_contract_transfer , gas_fee … ?
I got this error

These are the same list of OperationTypes you define in your /network/options endpoint. Very purposely, we don’t define any global operation types. You can read more about this philosophy here:
