    Returns permissions that a caller has on the specified resource. If the resource does not exist, this will return an empty set of permissions, not a NOT_FOUND error.

    Note: This operation is designed to be used for building permission-aware UIs and command-line tools, not for authorization checking. This operation may "fail open" without warning.

    Parameters
    Name Description
    request IamProtos. google.iam.v1.TestIamPermissionsRequest

    The request object that will be sent.
    options gax. CallOptions | Callback <IamProtos. google.iam.v1.TestIamPermissionsResponse , IamProtos. google.iam.v1.TestIamPermissionsRequest | null | undefined, {} | null | undefined>

    Optional parameters. You can override the default settings for this call, e.g, timeout, retries, paginations, etc. See [gax.CallOptions] https://googleapis.github.io/gax-nodejs/interfaces/CallOptions.html for the details.
    callback Callback <IamProtos. google.iam.v1.TestIamPermissionsResponse , IamProtos. google.iam.v1.TestIamPermissionsRequest | null | undefined, {} | null | undefined>

    The function which will be called with the result of the API call.

    The second parameter to the callback is an object representing [TestIamPermissionsResponse].
    Returns
    Type Description
    Promise <IamProtos. google.iam.v1.TestIamPermissionsResponse >

    {Promise} - The promise which resolves to an array. The first element of the array is an object representing [TestIamPermissionsResponse]. The promise has a method named "cancel" which cancels the ongoing API call.
