JSON Handling

Searchable keywords: JSON, serialize, deserialize, /ui2/cl_json, REST API, API response

CRITICAL: Always use /ui2/cl_json for JSON serialization and deserialization.

Correct Usage

" Deserialize JSON to ABAP structure
DATA ls_data TYPE ty_request.
ls_data = /ui2/cl_json=>deserialize( json = lv_json ).

" Serialize ABAP structure to JSON
lv_json = /ui2/cl_json=>serialize( data = ls_response ).

Never Use

• Manual string operations (CONCATENATE, SPLIT, etc.)
• String templates for complex structures
• Direct assignment without /ui2/cl_json

This is enforced by ABAP - manual string operations for JSON parsing will cause type conflicts.
