Horizontal customer support / ticketing software. Teams use Zendesk to (1) intake support requests across email, web form, chat, messaging, voice, and social into a unified ticket queue; (2) route and prioritize via business rules, SLAs, skills-based routing, and omnichannel routing; (3) deflect with Help Center knowledge bases, Web Widgets, and AI Agents (formerly Answer Bot/Ultimate); (4) collaborate via macros, side conversations, light agents, and CCs; (5) report on agent productivity, CSAT, FRT/resolution times via Explore; and (6) integrate deeply with Salesforce, Jira, Slack, Shopify, and 1,500+ marketplace apps.

For any business running customer support on Zendesk, the API exposes the operational heartbeat of CX: every ticket (status, priority, channel, requester, assignee, tags, custom fields, SLA timers), every conversation/comment, every macro/trigger/automation, organizations and users (the de facto customer directory), CSAT survey responses, help center articles and views, voice call records, chat transcripts, and AI Agent resolutions.

Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
