​
Overview

The Delete User Memory endpoint allows you to remove specific memories from a user’s memory profile. This is useful for maintaining data quality, removing outdated information, or giving users control over their stored personal data.

​
Functionality

  • Targeted Deletion: Removes a specific memory using its unique memory ID
  • User Context Validation: Ensures the memory belongs to the authenticated user
  • Immediate Removal: Permanently deletes the memory from the vector store
  • Confirmation Response: Returns clear success/failure status for the deletion operation
  • Tenant Isolation: Operates within the specified tenant/sub-tenant context

​
Use Cases

  • Data Cleanup: Remove outdated or incorrect memories
  • Privacy Compliance: Allow users to delete their personal data
  • Memory Management: Maintain high-quality memory profiles by removing irrelevant information
  • Error Correction: Delete memories that were added incorrectly
  • User Control: Give users the ability to manage their own memory data

​
Finding Memory IDs

To delete a memory, you first need to find its ID using the List User Memories endpoint: 
# First, list all memories to find the ID
curl -X GET "https://api.cortex.com/user_memory/list_user_memories?tenant_id=company_123&sub_tenant_id=marketing_team" \
  -H "Authorization: Bearer YOUR_API_KEY"

# Response will include source_id for each memory
{
  "success": true,
  "user_memories": [
    {
      "source_id": "mem_001_abc123",  # This is the memory_id to use
      "source_content": "User prefers detailed technical explanations..."
    }
  ]
}

# Then delete using the source_id
curl -X DELETE "https://api.cortex.com/user_memory/delete_user_memory?tenant_id=company_123&sub_tenant_id=marketing_team&memory_id=mem_001_abc123" \
  -H "Authorization: Bearer YOUR_API_KEY"

​
Important Notes

Permanent Deletion: Once a memory is deleted, it cannot be recovered. Make sure you have the correct memory ID before proceeding with deletion.
Memory ID Source: Memory IDs (source_id) can be obtained from the List User Memories endpoint or from the response of Add User Memory and Generate User Memory endpoints.
Best Practices:
  • Always verify the memory content before deletion using the List endpoint
  • Consider implementing user confirmation for memory deletion
  • Log deletion activities for audit purposes
  • Provide users with a way to review their memories before deletion
Pro Tip: For bulk memory management, you can combine this API with the List API to create a memory management interface that allows users to review and selectively delete their memories.
