Massdrop | Retail | 50 | $8M | United States | Easypost | Easypost SmartRate API | API Management | 2015 | n/a | In 2015, Massdrop implemented the Easypost SmartRate API as a core element of its API Management strategy to centralize multi-carrier shipping and label generation. Massdrop integrated USPS, USPS International, and UPS through EasyPost to reduce the development burden of building carrier-specific shipping features for each provider. The implementation used Easypost SmartRate API alongside EasyPost capabilities listed in the case study, including the Tracking API with Webhooks, Rates API, Customs, and Refunds. Massdrop configured the platform to generate prepaid and printable shipping labels for drop ship orders, and to use rate-shopping logic to determine the best shipping method based on price and speed, while performing address validation before postage purchase. Integrations extended to carrier account provisioning for USPS and UPS and to vendor drop ship flows, with webhooks providing near real-time tracking status updates into Massdrop order management. International address verification and customs support were implemented to support cross-border shipments and to ensure accuracy of delivery data at point of sale. Operational governance centralized shipping logic into the Easypost API layer, reducing complexity in backend services and enabling the product team to add courier options without expanding custom integrations. The consolidation simplified shipping operations, added real-time tracking and international address verification, and strengthened Massdrop customer experience and operational processes as reported in the case study. | |

Printful | Professional Services | 1600 | $150M | United States | Easypost | Easypost SmartRate API | API Management | 2014 | n/a | In 2014, Printful integrated the Easypost SmartRate API into its fulfillment stack to centralize shipping rate logic under an API Management approach. The decision supported Printful’s on-demand custom product service where rapid, API-driven order handling was required, and it followed experience with a third-party shipping API that lacked needed flexibility. Deployment included the Easypost SmartRate API together with EasyPost Tracking API with webhooks, Rates API, USPS International, Customs, and Refunds. Implemented capabilities focused on programmatic rate calculation and carrier selection, automated shipping label creation, and webhook-driven tracking updates, enabling labels and refund workflows to be driven directly from API calls. The integration was embedded into Printful’s in-house iOS warehouse application used at its Los Angeles facility, allowing employees to scan items, generate shipping labels, and wirelessly print labels from iOS-ready devices and a shipping label printer. Carrier connectivity explicitly covered USPS, FedEx, and UPS, and EasyPost support allowed Printful to distribute shipments across carriers to better manage cost and capacity, aligning shipping orchestration with fulfillment operations. Governance shifted toward API-first fulfillment workflows, with webhooks and the iOS application centralizing execution of pick, scan, label and print processes. Printful reported drastically reduced fulfillment time and the ability for employees to ship packages using only iOS devices and a label printer, outcomes the company credited with delivering operational flexibility and a competitive advantage in fulfillment efficiency. | |

SKULabs | Professional Services | 10 | $2M | United States | Easypost | Easypost SmartRate API | API Management | 2019 | n/a | In 2019 SKULabs implemented the Easypost SmartRate API as part of an API Management initiative to centralize carrier rating and label generation inside its multi-channel inventory and order fulfillment platform. Easypost SmartRate API was embedded into SKULabs core workflow to provide programmatic rate quotes and to drive consistent shipping label creation across the companys desktop, tablet, and mobile interfaces. The implementation leveraged EasyPost Carrier Rating and Shipping API capabilities alongside SmartRate driven rate selection to standardize weight, dimension, and address validation before label creation. Configuration work focused on mapping SKULabs order and warehouse pick pack workflows to API calls for rate retrieval, parcel validation, and postage purchase, enabling automated label generation tied to a given order record. Integrations connected the Easypost SmartRate API to SKULabs order management and warehouse management modules, allowing carrier choices surfaced via EasyPosts 100 plus carrier integrations to be presented to merchants and applied at shipment time. The deployment operated within SKULabs multi-channel operational scope, supporting orders originating from integrated shopping carts and marketplaces managed by SKULabs and routing fulfillment through EasyPost carrier endpoints. Governance centered on embedding API-driven shipping validation into existing fulfillment workflows, with rollout supported by developer integration and ongoing API support from EasyPost. SKULabs reported that onboarding required less developer time and resources, and the platform began generating shipping labels at the stated rate of one cent per label while reducing label generation errors through standardized API validation. | |
