Send a batch of pending approvals

<Warning> **Coming soon.** This endpoint will be available by early July 2026. </Warning>

<small>Requires the ai-sdr:write scope (or a broader one that includes it).</small>

Approves and sends the queued AI-generated messages for up to 20 (sequence, contact) pairs in one call. Bodies and subjects cannot be overridden in bulk — use the per-contact endpoint for that.

Requires the AI SDR feature on the caller's team.
