How to Integrate Third-Party Shipping Insurance via API (Secursus V2)

If you run an e-commerce store shipping valuable items, you've probably dealt with lost or damaged packages. Carrier declared value coverage (usually capped at $100) rarely covers the real cost. Third-party shipping insurance fills that gap. In this post, I'll walk through how to integrate the Secursus shipping insurance API into an e-commerce workflow. Secursus covers parcels up to $120,000 against loss, theft, and damage in transit across 30+ carriers (FedEx, UPS, USPS, DHL, etc.). Overview of the API The Secursus API V2 is REST-based and uses OAuth 2 for authentication. The main operations are: Authentication: Get access and refresh tokens via OAuth 2 Parcels (core operations): Get insurance fees (quote for a single parcel) Get insurance fees for many parcels (bulk quoting) Create a parcel (insure a shipment) Create many parcels (bulk insure) Retrieve, list, and cancel parcels Claims: Get, retrieve, and cancel claims Webhooks: Configurable notifications for parcel and claim status u
