- Worth noticing
- The page specifies 422 responses when SMS delivery is unavailable, plus per-recipient carrier failure reasons.
Field notes
OTP settings shown on the page cap codes at five attempts, expire them after five minutes, and rate-limit requests by phone number. Broadcasts begin with CSV upload and include duplicate merging, scheduled sends, unsubscribe suppression for email, and carrier-reported failure reasons. Webhook events include an HMAC-SHA256 signature and deduplication ID; the page says failed deliveries are retried up to five times with exponential backoff.
