The second parameter to the callback is an object representing [TestIamPermissionsResponse].

Returns

Type	Description
Promise<IamProtos.google.iam.v1.Policy>	{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.

testIamPermissions(request, options, callback)

testIamPermissions(request: IamProtos.google.iam.v1.TestIamPermissionsRequest, options?: gax.CallOptions | Callback<IamProtos.google.iam.v1.TestIamPermissionsResponse, IamProtos.google.iam.v1.TestIamPermissionsRequest | null | undefined, {} | null | undefined>, callback?: Callback<IamProtos.google.iam.v1.TestIamPermissionsResponse, IamProtos.google.iam.v1.TestIamPermissionsRequest | null | undefined, {} | null | undefined>): Promise<IamProtos.google.iam.v1.TestIamPermissionsResponse>;

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.
