API Overview
The CFJ-LINK enterprise API is built on a RESTful architecture, enabling B2B distributors, travel platforms, and enterprise clients to integrate global eSIM distribution directly into their products. All API endpoints use HTTPS (TLS 1.3) and are authenticated via API Key.
API documentation and sandbox environments are currently access-controlled to ensure platform stability and prevent abuse. Upon completing business review, partners receive full technical documentation, sandbox credentials, and dedicated integration support.
# Sandbox · authenticated example curl https://api.cfj-global.com/v1/plans \ -H "Authorization: Bearer $CFJ_API_KEY" \ -H "Accept: application/json" # → 200 OK · application/json { "object": "list", "data": [ /* plan objects */ ] }
API Capability Overview
Upon approval, partners gain access to the full RESTful API suite. Capabilities include plan discovery and real-time pricing, eSIM order creation and QR code delivery, profile activation tracking, near real-time usage queries, Webhook event push, and enterprise billing management. Full documentation, schemas, and SDKs are provided post-approval.
