Built for developers

A REST API for every action in the dashboard, signed webhooks for every event, and no surprises in between.

POST /v1/mailboxes

curl -X POST https://api.mailros.eu/v1/mailboxes \
  -H "Authorization: Bearer $MAILROS_KEY" \
  -d domain=northwind.studio \
  -d local_part=hello \
  -d quota_gb=5

Predictable REST

Every dashboard action has an endpoint. Cursor pagination, ISO timestamps, idempotency keys on writes.

Signed webhooks

HMAC-signed deliveries with retries and a replay tool for the last 72 hours.

Scoped keys

Per-key permissions and expiry dates. Secrets are shown once and never again.

Honest rate limits

Documented, per-key, and returned in response headers before you hit them.
