Photon iMessage App API

Photon's iMessage App API is a developer/API offering for bringing AI agents into iMessage conversations. Photon’s first-party pages describe iMessage APIs for sending, receiving, and acting in iMessage with direct messages, group chats, rich media, location sharing, mini apps, SMS/RCS fallback, and managed or dedicated infrastructure; docs expose both Spectrum iMessage provider usage and the low-level @photon-ai/advanced-imessage SDK.
