> 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.

# Create webhook destination

> Create webhook destination: createWebhookDestination in the TypeScript, Python and Rust clients.

`POST /v1/projects/{projectId}/webhooks/destinations`

Creates a webhook destination for the selected project using its URL, payload API version, event selection and other documented settings. The response includes the signing secret, which is returned only in this response and in idempotent replays of it, never by destination reads; store it securely for signature verification. The API version must be selectable and selected event types must belong to that version's catalog. Supply the required Idempotency-Key header.
