Review the Web API endpoints used to create keys, verify licenses, manage customers, and automate workflows. Find SDKs and platform-specific guidance for .NET, Python, Java, Node.js, C++, Go, and more. Integrate with coding agents using Devolens skills and llms.txt files, or connect MCP clients to query analytics and manage licensing with scoped permissions. Before publishing your integration, review the [troubleshooting guide](/getting-started/troubleshooting-guide) and the [checklist before publishing](/getting-started/checklist-before-publishing). ## Choose a licensing model Compare node-locked, floating, subscription, usage-based, trial, and user-based licensing models. Review common implementation patterns such as key verification, offline licensing, trials, and key generation. ## Production readiness For platform reliability and customer proof points, see [Why Choose Devolens](https://devolens.com/why-choose-devolens). Review privacy, GDPR, data protection, and security guidance for production licensing workflows. Support enterprise customers that need licensing in offline, on-premise, or restricted network environments. Verify expiry handling, activation behavior, access-token scope, and production configuration before launch. Plan a gradual transition from an internal licensing system or another provider without disrupting customers. ## Automate operations Connect payments to license creation, renewals, customer updates, and subscription workflows. Automate workflows such as payment success to license creation, CRM updates, and expiry reminders. Let customers manage licenses, view purchases, and access self-service licensing workflows. Invite resellers who can issue licenses and manage customers from their own portal. ## Manage in the dashboard Manage products, licenses, customers, account access, templates, and dashboard settings. Track license activity, usage trends, and customer behavior from the Devolens dashboard. Detect unusual usage patterns and investigate suspicious or failing license activity. Send update notices, announcements, and in-app messages to selected users or all users.
