SendCheck API

Programmatic access to deterministic deliverability checks, drift alerts, and PDF exports is on the roadmap. Here’s what we’re building—and how you can get early access.

Coming soon

Planned endpoints

We’re shipping a REST API first, followed by GraphQL support. Expect the same data model used internally by the SendCheck dashboard.

POST /v1/checks

Trigger deterministic SPF, DKIM, DMARC, and BIMI evaluations for a domain or subdomain. Responses mirror the remediation guidance you see in the dashboard.

GET /v1/checks/{id}

Retrieve the full results payload—including lookup depth, alignment warnings, BIMI readiness scores, and recommended DNS changes.

GET /v1/alerts

Stream drift alerts by severity so your incident tooling stays in sync with SendCheck’s nightly monitoring.

POST /v1/webhooks

Register webhooks for alert opened/closed events and PDF export completions. Built for Slack, PagerDuty, and custom CI flows.

SDKs & tooling roadmap

  • Official TypeScript SDK with first-class support for Edge environments and Node 18+.
  • Go client for integrating directly into infrastructure automation pipelines.
  • CLI scaffolding (`npx SendCheck`) to trigger checks, fetch alerts, and export reports without leaving the terminal.
  • Terraform provider for managing workspace domains, alert routes, and integrations as code.

Join the beta cohort

We’re inviting a small group of partners to validate webhooks, API limits, and SDK ergonomics. Share your use case and we’ll get in touch with credentials once the preview is ready.

FAQ

When will the API launch?
Private preview begins in Q2. General availability follows once rate limiting, billing, and documentation are battle-tested.
Will usage be metered?
Every paid plan will include a generous allotment of checks and webhooks. High-volume use cases can add consumption-based tiers.
Do you support on-prem?
The API is cloud-hosted, but we’re exploring a managed VPC deployment for regulated teams. Let us know if that’s critical for you.
