### Crie a *operação de rota* do callback

Para criar a *operação de rota* do callback, use o mesmo `APIRouter` que você criou acima.

Ele deve parecer exatamente como uma *operação de rota* normal do FastAPI:

	}

	if cap(t.requestsPool) != apiRequestsMaxPerNode {
		// Only replace if needed.
		// Existing requests will use the previous limit,
		// but new requests will use the new limit.
		// There will be a short overlap window,
		// but this shouldn't last long.
		t.requestsPool = make(chan struct{}, apiRequestsMaxPerNode)
	}
	listQuorum := cfg.ListQuorum

		},
		config.HelpKV{
			Key:         ClaimPrefix,
			Description: `[DEPRECATED use 'claim_name'] JWT claim namespace prefix e.g. "customer1/"` + defaultHelpPostfix(ClaimPrefix),
			Optional:    true,
			Type:        "string",
		},
		config.HelpKV{
			Key:         RedirectURI,

	ETag         string
	Size         int64

	// Owner of the object.
	Owner *Owner `xml:"Owner,omitempty"`

	// The class of storage used to store the object.
	StorageClass string

	// UserMetadata user-defined metadata
	UserMetadata *Metadata `xml:"UserMetadata,omitempty"`
	UserTags     string    `xml:"UserTags,omitempty"`

	Internal *ObjectInternalInfo `xml:"Internal,omitempty"`
