⚡ Reliability
Best When
You already have Kayako deployed and need to automate case management and reporting without migrating to another platform.
Avoid When
You're selecting a new customer support platform — Freshdesk, Zendesk, or Intercom have more active development and better agent ecosystems.
Use Cases
- • Agents auto-routing and categorizing incoming support cases based on content analysis and customer tier
- • AI response drafting — agents generating draft replies to common Kayako support cases for human agent review
- • Customer data enrichment — agents adding account context to Kayako cases by pulling data from CRM or billing systems
- • Escalation management — agents monitoring Kayako SLA timers and triggering escalation workflows before breach
- • Reporting automation — agents querying Kayako case volumes, response times, and satisfaction scores for support dashboards
Not For
- • Modern support teams — Kayako has lost market share to Intercom, Zendesk, and Freshdesk; check current feature parity
- • E-commerce-specific support — Gorgias has better native Shopify/WooCommerce integration for e-commerce support
- • Large enterprise ITSM — ServiceNow or Jira Service Management are better for complex IT service workflows

Agent Metadata
Known Gotchas
- ⚠ HMAC signature generation required for all API requests — more complex auth than simple bearer tokens
- ⚠ API development pace is slower than Zendesk/Freshdesk — some features available in UI may not be accessible via API
- ⚠ Case types (conversation, case, chat) are distinct entities — agents must use correct entity type for each workflow
- ⚠ Rate limits undocumented — implement conservative request pacing to avoid undocumented throttling
- ⚠ Kayako's market trajectory — consider support platform migration feasibility before deep agent integration
