About this gig

Do you need a secure custom API that allows an external application to communicate with Salesforce?

I will design and develop custom Apex REST web services based on your requirements and Salesforce data model.


Services include:


  • Custom Apex REST endpoints
  • GET, POST, PUT, PATCH and DELETE
  • JSON request and response wrappers
  • Input validation and business rules
  • Structured success and error responses
  • Salesforce queries and record updates
  • Bulk-safe Apex development
  • Sharing and security considerations
  • Apex test classes
  • Postman collection
  • Endpoint and payload documentation
  • Deployment preparation

The API will follow an agreed scope for reliable communication between Salesforce and external systems.
