Need to send shipment ID to OIC after a regular interval

Summary:

We want to get tracking events from external application using OIC but external application is not capable of sending those events directly,

So OIC has to fetch those events from external application and send those in OTM but OIC doesn't have shipment IDs so OTM has to first send them shipment ID and then OIC will fetch tracking event from external application and then corresponding to thaat shipment OIC will send events

So how can we send those shipment ID after a regular interval to OIC?
