Slack Web API breaking changes, fixed in a PR

Versionly diffs Slack's public Web API OpenAPI spec, tracks changelog updates, and maps block kit, messaging, and OAuth call sites to reviewable patches.

What breaks without monitoring

  • Method parameters rename across API tiers
  • Event payload shapes change for apps and bots
  • OAuth scopes and token response fields evolve

How Versionly helps

  • slack_web_openapi spec monitoring
  • @slack/* and @slack/web-api detection
  • Auto-fix suggestions for affected handlers
