> ## Documentation Index > Fetch the complete documentation index at: https://docs.photon.codes/docs/llms.txt > 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. # Retry webhook delivery > Requests an immediate attempt of the selected delivery if it is still the waiting head for its destination and event type. expectedAttemptCount is the failed-attempt counter recorded on the delivery and fences stale requests. This overrides the current backoff, including Retry-After, once. It preserves event identity and the retry budget. Delivered, active, disabled and dead-lettered deliveries cannot be retried. A 202 acknowledges the wake-up, not successful delivery. Supply an Idempotency-Key and retain it when retrying an ambiguous failure. ## OpenAPI ````yaml https://api.photon.codes/openapi.json post /v1/projects/{projectId}/webhooks/destinations/{destinationId}/retries openapi: 3.1.0 info: title: Photon API version: 1.0.0 servers: - url: https://api.photon.codes security: [] paths: /v1/projects/{projectId}/webhooks/destinations/{destinationId}/retries: post: tags: - Webhook Delivery summary: Retry webhook delivery description: >- Requests an immediate attempt of the selected delivery if it is still the waiting head for its destination and event type. expectedAttemptCount is the failed-attempt counter recorded on the delivery and fences stale requests.
