> 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.

# Get WhatsApp Business verification code

> Get WhatsApp Business verification code: getWhatsappBusinessVerificationCode in the TypeScript, Python and Rust clients.

`GET /v1/projects/{id}/platforms/whatsapp-business/numbers/{resourceId}/verification-code`

Returns the latest six-digit WhatsApp Business ownership code received by SMS for an active Photon VOIP number, but only when its provider timestamp is strictly newer than the required receivedAfter boundary. receivedAfter must be an RFC 3339 timestamp between this request's arrival time and two minutes before it; once it expires, restart Meta's verification flow with a new boundary. A missing newer code is a retryable 404 with Retry-After: 2. Poll after 2, 4, 8, then 10 seconds, applying ±20% jitter and capping later intervals at 10 seconds. Stop when the original boundary is two minutes old. Responses are never cached. Requires the platforms:write permission bound to the project resource in the path.
