YouTube Data API - Errors

This document identifies the different types of errors that YouTube Data API operations can return. You can also find a list of errors for any individual method in the reference documentation for that method.

General errors

The following tables identify API error messages that are not specific to a particular API method.

Core API errors

Error type Error detail Description
forbidden (403) forbidden Access forbidden. The request may not be properly authorized.
quotaExceeded (403) quotaExceeded The request cannot be completed because you have exceeded your quota.

Common request errors

Error type Error detail Description
badRequest (400) incompatibleParameters The request specifies two or more parameters that cannot be used in the same request.
badRequest (400) invalidFilters The request specifies an invalid filter parameter.
badRequest (400) invalidPageToken The request specifies an invalid page token.

badRequest (400) unexpectedParameter The request specifies an unexpected parameter.
forbidden (403) accountDelegationForbidden The authenticated user cannot act on behalf of the specified Google Account.
forbidden (403) authenticatedUserAccountClosed The YouTube account of the authenticated user is closed. In case the authenticated user is acting on behalf of another Google Account, then this error refers to the latter.
forbidden (403) authenticatedUserAccountSuspended The YouTube account of the authenticated user is suspended. In case the authenticated user is acting on behalf of another Google Account, then this error refers to the latter.
forbidden (403) authenticatedUserNotChannel For this request the authenticated user must resolve to a channel, but does not. If your request is authenticated and uses the onBehalfOfContentOwner delegation parameter, then you should also set the onBehalfOfContentOwnerChannel parameter.
forbidden (403) channelClosed The channel identified in the request has been closed.
forbidden (403) channelNotFound The channel identified in the request cannot be found.
forbidden (403) channelSuspended The channel identified in the request has been suspended.

forbidden (403) insufficientPermissions The OAuth 2.0 token provided for the request specifies scopes that are insufficient for accessing the requested data.
notFound (404) contentOwnerAccountNotFound The specified content owner account was not found.

Request context errors

Error type Error detail Description
badRequest (400) invalidLanguage The hl parameter value does not specify a valid language code.
badRequest (400) invalidMine The request's use of the mine parameter is not supported.
badRequest (400) invalidMine The mine parameter cannot be used in requests where the authenticated user is a YouTube partner. You should either remove the mine parameter, authenticate as a YouTube user by removing the onBehalfOfContentOwner parameter, or act as one of the partner's channels by providing the onBehalfOfContentOwnerChannel parameter if available for the called method.
badRequest (400) invalidPart The request's part parameter specifies some parts that cannot be written at the same time.
badRequest (400) invalidRegionCode The regionCode parameter specifies an invalid region code.
badRequest (400) unexpectedPart The request's part parameter specifies an unexpected value.

badRequest (400) unsupportedLanguageCode The hl parameter value does not specify a supported language code.
badRequest (400) unsupportedRegionCode The regionCode parameter specifies an unsupported region code.
unauthorized (401) authorizationRequired The request uses the mine parameter but is not properly authorized.
unauthorized (401) youtubeSignupRequired This error indicates that the user has an unlinked Google Account, which means that the user has a Google Account but does not have a YouTube channel. Such users can access many features that are dependent on user authorization, such as rating videos or adding videos to a watch_later playlist. However, as an example, the user would need a YouTube channel to be able to upload a video. A user who has a Gmail account or an Android device is certain to have a Google Account but may not have already linked that Google Account to a YouTube channel.

This error is commonly seen if you try to use the OAuth 2.0 Service Account flow. YouTube does not support Service Accounts, and if you attempt to authenticate using a Service Account, you will get this error.

The YouTube API blog post introducing Google Account support also discusses the youtubeSignupRequired error in more detail. Although the blog post explains the error for API version 2.1, the meaning of the error is still applicable.
