If you want to export a record only once give this option. Also, we need to provide a Boolean field to mark records as exported
Boolean field to mark records as exported : Please select a boolean field (i.e. a checkbox field) from the export application that integrator.io can use to keep track of records that have been exported or not. Please note that integrator.io will only export all records where this booean field is false (i.e. unchecked), and integrator.io will also automatically make a subsequent request back into the export application to set this boolean field to true for all the records that were exported (so that those records are not exported again).
