    QuickBooks Online Webhooks provide near real-time notifications when data
    changes in a QuickBooks Online company. When an entity is created, updated,
    merged, deleted, or voided, Intuit sends an HTTP POST notification to your
    registered endpoint. Webhook notifications are delivered as JSON payloads
    and are signed with an HMAC-SHA256 signature using your webhook verifier
    token. Your endpoint must respond with an HTTP 200 status within 10 seconds.
    Notifications may be batched, delivering multiple entity change events in a
    single payload. Notifications are sent on a best-effort basis and may arrive
    out of order; your application should use the query API to retrieve the
    current state of changed entities.

    summary: Receive entity change notifications from QuickBooks Online
    description: >-
      Your application receives webhook notifications when entities in a
      QuickBooks Online company are created, updated, merged, deleted, or
      voided. The notification payload contains metadata about the changes
      but not the full entity data. Your application should use the
      QuickBooks Online Accounting API to query for the current state of
      changed entities.

          HMAC-SHA256 signature of the payload body using your webhook
          verifier token as the key. Your application must validate this
          signature to verify the notification came from Intuit. Compute
          the HMAC-SHA256 hash of the raw request body using your verifier
          token, then Base64 encode the result and compare it with the
          intuit-signature header value.
