Conversations already include custom_attributes as key-value pairs in the API response, but there’s no way to filter or search conversations by those attributes via the Search Conversations API (even though this is possible in the Intercom UI).
This creates a gap where teams can segment conversations in the UI but can’t do the same programmatically, which limits automation, reporting, and integrations that rely on custom attributes. It’s also inconsistent with other areas where attribute-based filtering exists (for example, the Tickets API).
Intercom, we are in 2026, we have Claude Code etc, this feature is just a one-shot query for AI implementation 🙏
