# Send a test ping to the webhook

> Queues one signed ping event (see webhooks, ping) to the partner's webhook URL, delivered the way every event is: a POST of the event as JSON, signed in the Standard Webhooks scheme. Use it to check that the endpoint is reachable and that its signature check accepts MyPilotIndex's signature. The answer is 202 once the ping is queued, before it is delivered; each call is one ping with a new event id. The webhook URL and its secret are set by MyPilotIndex when the partner is approved: a partner without a webhook URL, with a URL that is not https, or without a secret on record answers 409 conflict with reason webhook_not_configured, and nothing is queued. The request has no body (an empty JSON object is accepted). Like every partner call it counts toward the daily allowance and is logged.

  title: MyPilotIndex Partner API
  version: 1.0.0
  description: >-
    The API of approved partner applications, such as logbooks, that act for a
    pilot who has granted them access on the MyPilotIndex consent screen. It is
    a separate document from the member API (openapi.yaml): partner routes live
    under /v1/partner/ and are never served to browsers. Authenticate with an
    access token from the identity provider's token endpoint
    (grant_type=client_credentials, scopes partner/<scope>) in the Authorization
    header. Every authenticated answer carries X-RateLimit-Limit and
    X-RateLimit-Remaining, the partner's daily allowance and what is left of it
    (a 401, and a path or method outside this document, carry neither); past the
    allowance the API answers 429 rate_limited with Retry-After. Errors use the
    shared envelope below. The API is additive within v1: new fields and routes
    may appear, existing ones do not change meaning.

    description: >-
      A pilot connects on MyPilotIndex: the partner sends his browser to the
      consent page
      (https://mypilotindex.com/connect/{slug}?client_id&redirect_uri&scope&state&code_challenge&code_challenge_method=S256),
      the pilot signs in and allows, and the browser returns to the registered
      redirect_uri with code and state (or error=access_denied and state when he
      denies). The partner exchanges the code here for a grant and the pilot's
      pairwise id, which signs the pilot in ("Sign in with MyPilotIndex") and
      names him on every later call. A grant that is revoked, unknown or another
      partner's answers 404 on every route, identically.
  - name: Certificates
    description: >-
      Check a certificate a pilot shows you, such as his MPI Report, by its
      public id. The answer is the public verification's, and the call needs no
      grant.
  - name: Webhooks
    description: >-
      MyPilotIndex tells a partner about its grants by webhook: grant.revoked
      when a grant ends, and ping when the partner asks for a test. The webhook
      URL (https only) and its signing secret are set by MyPilotIndex when the
      partner is approved; the secret is shown once. Each event is a POST of the
      event as JSON (Content-Type application/json) signed in the Standard
      Webhooks scheme: webhook-id (the event id), webhook-timestamp and
      webhook-signature, "v1," and the base64 HMAC-SHA256 of
      "<webhook-id>.<webhook-timestamp>.<body>" under the key the secret carries
      in base64 after its whsec_ prefix, over the exact bytes received. Verify
      the signature, refuse a timestamp more than five minutes from your clock,
      dedupe on webhook-id, and answer any 2xx within 10 seconds. A 5xx, a 408,
      a 429, a redirect (never followed), a timeout or a connection failure is
      retried with growing gaps for about a day (twelve attempts), with the same
      webhook-id and a fresh timestamp and signature. A 4xx other than 408 and
      429 is taken as a refusal and not retried, except for a grant.revoked
      event with reason account_deleted: its grant leaves every list with the
      account, so it cannot be reconciled later, and it is retried within the
      same window on any answer but a 2xx, a 4xx included. A partner that missed
      other events reconciles with GET
      /v1/partner/grants?status=revoked&changed_since=.
