YouTube Data API - Errors

AI-generated Key Takeaways

The YouTube Data API commonly returns errors such as forbidden (403) for authorization issues, badRequest (400) for invalid requests, and notFound (404) for missing resources.
Specific API methods like activities, captions, channelBanners, channelSections, playlists, and videos have unique error conditions, including missing parameters, content issues, and permission constraints.
Errors related to channel management, such as creating, deleting, listing, or updating channel sections or playlists, often involve issues with invalid IDs, missing required fields, exceeding limits, or conflicting configurations.
Comment and comment thread errors can arise from insufficient permissions, disabled commenting, character limits, private comments, or attempting to reply to non-existent parent comments.
Errors related to video operations may include problems with category IDs, descriptions, titles, privacy settings, invalid licensing, missing content, exceeding upload limits, and improper reporting of abuse.

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)`	`missingRequiredParameter`	The request is missing a required parameter.
`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)`	`cmsUserAccountNotFound`	The CMS user is not allowed to act on behalf of the specified content owner.
`forbidden (403)`	`insufficientCapabilities`	The CMS user has insufficient capabilities.
`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)`	`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.
