Guides

Narrative walkthroughs for the Helium MVNE platform. Pair these with the API reference for endpoint-level detail.

Get started

  • Quickstart
    From invite-accept to first webhook in 10 minutes, curl-only.
  • Authentication
    Publishable vs restricted keys, rotation, bearer-token mechanics.
  • Roles & permissions
    The operator RBAC matrix — team roles, the permission grid, and CPNI step-up for PII.
  • Environments & mode
    Sandbox vs live, Stripe-style. Key scoping and graduation.

Platform primitives

  • Idempotency
    24h replay window, scoping, safe retries.
  • Rate limiting
    Tiers, response headers, backoff strategy.
  • Webhooks
    Registration, HMAC verification, retries, dead-letter, redelivery.
  • Errors
    Problem Details, error-code catalog, common 4xx patterns.
