Orchestrate a mid-term policy endorsement issuance workflow end-to-end

Steps

1. Receive the endorsement request via API or agent portal: capture the policy number, effective date of change, change type (e.g., add vehicle, change address, add driver), and new data values.
2. Validate the requested effective date against the policy term and any state-mandated minimum advance notice requirements for the change type; reject requests with an effective date in the past beyond your carrier's backdating rules.
3. Invoke the rating engine API with the updated risk characteristics to calculate the revised premium for the remainder of the policy term; receive the new annual premium and the pro-rated endorsement premium (see your carrier's pro-rata/short-rate rules for the calculation methodology).
4. If underwriting rules require review (e.g., added driver with major violations), route the endorsement to an underwriting queue and suspend issuance pending approval; otherwise auto-issue.
5. POST the approved endorsement to the policy admin system's endorsement issuance endpoint; receive the updated policy object, endorsement number, and revised declarations.
6. Deliver the endorsement documents (updated dec page, endorsement form) to the insured and agent via the configured delivery method (email, portal, mail), and update billing for any additional or return premium.
