> Use this file to discover all available pages before exploring further.

> ## Agent Instructions
> Use Stable documentation by default. Honor an explicit Beta request or a URL under /docs/beta/. If the requested version conflicts with the installed CLI package or API origin, clarify the target before writing integration code.
> Pages under /docs/beta/ document Beta; other product pages document Stable. Keep the CLI package, commands, API origin, and credentials within the selected version. State the documentation version in your answer.
> For MCP search, always pass version: Stable or version: Beta. Unfiltered search mixes both versions. For filesystem reads, keep Beta queries under /beta/ and exclude /beta/ from Stable queries; discover paths before reading them.
> The public docs base is https://photon.codes/docs. Convert MCP page paths to public URLs under that base, preserving /beta/ when present. Read https://photon.codes/docs/skill.md for version selection and https://photon.codes/docs/llms.txt for the version indexes.

# Provision dedicated WhatsApp line

> Provision dedicated WhatsApp line: provisionWhatsappDedicatedLine in the TypeScript, Python and Rust clients.

`POST /v1/projects/{id}/platforms/whatsapp/dedicated`

Provisions one dedicated WhatsApp line with WhatsApp and shared Voice enabled. It attaches to an eligible iMessage line the project already owns when possible so both products keep the same number; otherwise it claims healthy, available WhatsApp-capable dedicated-line inventory. Always answers 202, because waiting when no inventory is available is not a failure. The product opens its own charge period after the abilities are enabled; Voice has no separate charge. Waiting requests are served first come, first served, and are cancelled with a `reason` exactly as for a dedicated iMessage line. Cancel the returned operation to stop waiting. The Idempotency-Key is required and permanent.
