> 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 signup config

> Get WhatsApp signup config: getWhatsappSignupConfig in the TypeScript, Python and Rust clients.

`GET /v1/projects/{id}/platforms/whatsapp-business/signup-config`

Returns what the browser needs to open Meta's Embedded Signup popup: the Facebook Login for Business configuration id, the Graph version to run against, and the scopes it will request. Answered in-process rather than forwarded, so the first step of onboarding survives an outage of the private service. Pass `configId` to `FB.login` as `config_id` with `response_type: 'code'` and `override_default_response_type: true`. Do NOT add a `featureType` — omitting it is what keeps the phone-number screen in the flow, and `only_waba_sharing` produces an account with no number that cannot be provisioned. Requires the platforms:read permission bound to the project resource in the path.
