SMS routes renamed.
route on GET /v1/sms/coverage is now southern-africa (South Africa and its neighbours) or pan-africa (the rest of the continent). The previous values are no longer returned. The SMS guide explains that a route names the group of countries a message shares infrastructure with, not the partner that carries it.Send before your domain is verified.
POST /v1/emails accepts onboarding@sendbaze.com as from with a live key before any domain is verified. Delivery is limited to the organisation’s own addresses and the Amazon SES simulator addresses, 100 emails in total per organisation. Two new errors: 403 sandbox_recipient_not_allowed and 403 sandbox_limit_reached, both with a domainsUrl. New guide: send before your domain is verified.402 payment_required redefined. It now means usage beyond the allowance stayed unpaid for 24 hours after the saved card was declined.
