One API key for all your subaccounts

Your master API key can now act on behalf of any subaccount - plus multi-recipient voice calls with a single API request.

API

Manage subaccounts with your master API key - No more juggling one API key per account. Send the X-Account-Id header and your master key acts on behalf of a subaccount - sending, configuring and reading data as if you were logged in as that account. Enable it per key with the new subaccount access toggle in the developer settings.
Call many recipients with one request - The Voice API now accepts multiple recipients in a single call and fans the calls out asynchronously - perfect for alerting a whole on-call team at once.

Webhooks - Webhook updates are now true partial updates: only the fields you send change, everything else stays untouched.

Billing & Payments - Various fixes around Stripe statement descriptors, PayPal vault handling, invoice labelling and periods.
WhatsApp - Template messages are billed correctly per message, and template errors are surfaced instead of silently dropped.
