OAuth for Zapier, Make, n8n

Standard OAuth 2.0 — Inbox Check in your automation stack as a first-class integration.

Deliverability monitoring belongs in the same workflow as sending, not in a sidebar dashboard nobody checks. Our OAuth 2.0 flow means Zapier, Make, n8n, and any other tool that speaks OAuth can call Inbox Check with real user-scoped authentication.

Actions & triggers
  • Action: Run placement test. Input draft + providers, get test token.
  • Action: Get test result. Poll test, return placement + per-provider breakdown.
  • Trigger: Placement drop. Fire when weekly placement drops > X points.
  • Trigger: Folder flip. Fire when a provider moves your mail to Spam post-send.
  • Trigger: Auth record change. Fire when SPF/DKIM/DMARC unexpectedly changes.

Common automations

  • Every new campaign draft gets auto-placement-tested before send (Zapier/Make).
  • Weekly digest into client-specific Slack channels (n8n).
  • Sequence auto-pauses when folder flip detected.
  • Ticket auto-created in HelpScout/Linear when DMARC alignment breaks.

Setup

  • In Zapier: “Inbox Check” app, sign in via OAuth prompt.
  • In Make: “Inbox Check” module, add OAuth 2.0 connection.
  • In n8n: community node inbox-check, add OAuth2 credential.
  • Custom: hit /oauth/authorize/oauth/token, use bearer token on API calls.

FAQ

Does OAuth give me higher rate limits?
