Extensibility for TMF APIs

Salesforce’s TMF API extensibility framework enables customers to modify standard TMF-compliant APIs to meet specific business requirements while maintaining interoperability and scalability. Customers extend TMF schemas through the TMF extension model, and Salesforce provides a backend framework that supports custom mappings, validations, transformations, and lifecycle hooks.

This framework enables customers to implement custom logic and additional attributes across TMF operations while adhering to platform guidelines for scalability, data integrity, and compliance.

Key Features

• Flexible Field and Entity Mapping

  • Remap TMF payload fields to different Salesforce fields or objects
  • Support both standard and custom entities
  • Extend responses by adding or reshaping fields

• Attribute Extensibility

  • Allow customers to introduce additional TMF fields or sub-resources
  • Map newly added schema elements to Salesforce data structures

• Advanced Query Extensibility

  • Support custom filtering, sorting, and pagination
  • Enable object-level query extensions

• Custom Validations

  • Allow business-specific validation rules to be plugged into the request lifecycle
  • Support pre- and post-processing validation logic

• Transformations and Execution Hooks

  • Provide lifecycle hooks for request/response transformation
  • Support overrides for core transformation, pre-processing, and post-processing logic

• Inbound and Outbound API Extensibility

  • Apply custom logic to incoming API requests and outgoing API responses
  • Enable modifications for TMF (GET/POST/PATCH/DELETE) operations
