Hello, I can help you build a clean, reliable Apex integration that keeps Salesforce in sync with your external CRM. I’ve delivered several custom API integrations where we handled raw HTTP callouts, webhook processing, JSON handling, retry logic, and near-real-time updates without using middleware. In one of my recent projects, I built a full bidirectional sync between Salesforce and an external order-management system. We created custom REST endpoints, consumed their APIs, processed webhooks, updated order statuses inside Salesforce, and triggered confirmation/notification emails automatically. The setup also included batching, error logging, and retry handling to stay within governor limits. For your requirement, I can deliver: • Apex classes for all callouts + authentication/token handling • Bidirectional sync for Accounts, Contacts, and Activities • Triggers or Platform Events where needed to keep updates decoupled • Solid error handling, retry logic, and clean inline documentation • 75%+ test coverage with realistic mocking • A short setup guide so your admin team can deploy safely to production Once you share the API documentation (auth flow, token generation, endpoints, payload formats), I can start designing the integration immediately. If you prefer, just share the name of the external CRM and I can review what’s available. Happy to work remotely on a schedule that suits you.
