Routeon Email API — Email & OTP

Tenant-facing REST API for the email marketing platform. All responses use the standard envelope (status, http_code, payload, meta). Authentication is via per-tenant API keys (Bearer sklive…).

Rate limiting applies to every authenticated, tenant-scoped operation in this document — token buckets of 1000 req/min per API key and 5000 req/min per tenant, enforced for every request. Any such operation can therefore answer 429 as described by the RateLimited response, carrying Retry-After and the X-RateLimit-* headers, even where the operation does not list a 429 of its own. Operations that DO list a 429 do so because they have an additional source of it — e.g. a per-tenant daily send limit (/transactional/send) — and those variants are distinguished by meta.details.code.
