To complete a sale, you may want to “recall” a 4473 to link a pending disposition (with its associated 4473) to records in a point of sale system, for example.
In addition to an API for retrieving all pending dispositions for an account with an optional filter to also include 4473s, FastBound has an API method for retrieving pending dispositions that are related to 4473s where regular dispositions are not included.
