Integrator fee (as a decimal) charged on the notional filled by this order.
For example, 0.0005 represents a 0.05% fee. This value must not exceed
the maxIntegratorFee that the user approved for this integrator. The fee
follows the order, so it is collected on taker and maker fills alike.
Numeric integrator id (as assigned by the registry) of the integrator who will receive the fee.
This integrator must have been previously approved by the account owner.
Optional integrator fee configuration for an order.
Integrators register once globally and are assigned a numeric
integratorId. A user then approves an integrator by creating an integrator config with amaxIntegratorFee(see ApiPerpetualsBuilderCodesCreateIntegratorConfigTxBody). Orders placed on that user's behalf attach the integrator id and the fee to charge here.The fee is charged on the notional filled by the order and follows the order, so it applies to both taker and maker fills.
