The purpose of this article is to help you deal with the errors that may be returned during this operation.\n\nThe APIs used to integrate sellers’ SKUs can be found at: [https://developers.vtex.com/docs/api-reference/marketplace-apis](https://developers.vtex.com/docs/api-reference/marketplace-apis)\n\nWhen SKUs are entered via API, some errors may be returned in addition to the confirmed success returns. These errors are listed in the following table: each of them is identified by a number from 0 to 23 (apart from errors 99 and 999, which are unknown errors). The column on the left shows the names describing each error.\n\nFrom this table you can see what the errors returned in the integration refer to, so that the SKU suggestions can be handled and approved successfully.\n\n| Error     | Code     |\n| ---------- | ---------- |\n| NotSpecifiedError     | 0     |\n| MatchCategoryIdIsEmpty       | 1       |\n| MatchBrandIdIsEmpty       | 2       |\n| ProductNameIsEmpty       | 3       |\n| SkuNameIsRequired       | 4       |\n| SkuHeightIsRequired       | 5       |\n| SkuWeightIsRequired       | 6       |\n| SkuLengthIsRequired       | 7       |\n| SkuWidthIsRequired       | 8       |\n| SkuImagesAreRequired       | 9       |\n| EanOrRefIdAreRequired       | 10       |\n| SkuImageUrlIsInvalid       | 11       |\n| ProductOrSkuHasInvalidSpecificationLength       | 12       |\n| MatcherIdRequired       | 13       |\n| MatchSkuRefIsNotValid       | 14       |\n| MatchScoreIsNotInRange       | 15       |\n| SuggestionNotFound       | 16       |\n| MatchOldVersion       | 17       |\n| SuggestionIsNotPending       | 18       |\n| MatchBrandIdIsInvalid       | 19       |\n| MatchCategoryIdIsInvalid       | 20       |\n| MatchProductRefIsInvalid       | 21       |\n| SellerIdAndMarketplaceSkuIdAlreadyExists       | 22       |\n| SellerIdAndSellerSkuIdAlreadyExists       | 23       |\n| Unknown error (error of communication with the catalogue; we are working on a better description)       | 99       |\n| Unknown error (error of communication with the catalogue; we are working on a better description)       | 999       |"}
