## Viber Business Messages / REST Bot API

- `storage/viber-business-messages-rest-bot-api` | fails-quota | evidence reported | binding none | category messaging
- identity a placeholder: card and phone unknown | verified 2026-10-21 (inherited) | stale on 2026-11-05
- url https://developers.viber.com/docs/api/rest-bot-api/
- free tier: No storage quota — same inversion as Kakao: you pass a picture URL, Viber fetches it. Max image 1 MB on iOS, 3 MB on Android, thumbnail 100 KB. | unit: MB | metered on: stored-bytes | read on: 2026-10-21 | source: [1]
- per-object cap: not stated | source: [1] | note: not stated
- retention: not stated | source: [1] | note: not stated
- egress: N/A — Viber hosts nothing for you. It requires 'The URL must have a resource with a .jpeg, .png or .gif file extension as the last path segment', i.e. it is a consumer of your public URLs. | metered: no
- identity: email
- interface: rest
- limits note: 1 MB (iOS) / 3 MB (Android) image cap applies to the file YOU host; Viber rejects larger. Business messaging also requires partner onboarding for phone-number-based sends.
- interface detail: rest
- tooling: viber-bot-python / raw REST POST to https://chatapi.viber.com/pa/send_message. Sender-only API.
- composes with: Not chainable. No upload, no media_id, no listing, no retention — structurally incapable of storing a byte.
- reliability: N/A for storage.
- notes: the same as the free tier
- extras:
  - dead_end.failure_class: quota
  - dead_end.why: No storage quota — same inversion as Kakao: you pass a picture URL, Viber fetches it. Max image 1 MB on iOS, 3 MB on Android, thumbnail 100 KB.
