Update your resources and SDF generation actions to use v8.\n2. Update Ad resource logic to identify a type upon creation.\n3. Add new logic for reading, creating, and updating Demand Gen resources.\n\n### Update Structured Data Files version\n\nTo use a new Structured Data Files version, update the assigned version in your\nparent Partner and Advertiser resources and use the new version when creating\nindividual download tasks in the [Display \\& Video 360 API](/display-video/api).\n\n#### Update parent resource settings\n\nA default Structured Data Files version is set at the partner and advertiser\nresource level. This version is used as the default when downloading Structured\nData Files through the interface or API.\n\n##### Set in the interface\n\n**At the partner level**\n\n1. Navigate to the intended partner.\n2. Expand the **Partner settings** menu in the left-hand navigation and navigate to the **Basic details** page.\n3. Update the **SDF version** configuration in the **Structured Data Files** section to **v8**.\n\n**At the advertiser level**\n\n1. Navigate to the intended advertiser.\n2. Expand the **Advertiser settings** menu in the left-hand navigation and navigate to the **Basic details** page.\n3. Update the **SDF version** configuration in the **Structured Data Files** section to **v8**. If the default version is set at the Partner level, this setting may not be editable.\n\n##### Set in the API\n\nAt the partner level\n: You cannot set the default SDF version at the Partner level in the API.\n\nAt the advertiser level\n: Make an [`advertisers.patch`](/display-video/api/reference/rest/current/advertisers/patch) request to update the\n [`dataAccessConfig.sdfConfig.sdfConfig.version`](/display-video/api/reference/rest/current/SdfConfig#FIELDS.version) to\n `SDF_VERSION_8` and, if needed,\n [`dataAccessConfig.sdfConfig.overridePartnerSdfConfig`](/display-video/api/reference/rest/current/advertisers#AdvertiserSdfConfig.FIELDS.override_partner_sdf_config)\n to `True`.\n\n#### Update `sdfdownloadtasks.create` requests in the API\n\nWhen making a [`sdfdownloadtasks.create`](/display-video/api/reference/rest/current/sdfdownloadtasks/create) request using the\nDisplay \\& Video 360 API, set the [`version`](/display-video/api/reference/rest/current/sdfdownloadtasks/create#body.request_body.FIELDS.version) field of the\nrequest body to `SDF_VERSION_8`.\n\n### Specify type in Ad resources\n\nv8 adds an `Ad Type` column to [Ad](/display-video/api/structured-data-file/v8/AdGroupAd) files, which surfaces the type of\nAd represented by each row. This new column is required and will be populated\nfor existing resources when downloading v8 Ad files.\n\nWhen updating existing Ads, the value of this column shouldn't be changed.\n\nWhen creating new Ads, you must populate this column with one of the values\nlisted in the column description.\n\n### Update logic for Demand Gen resources\n\nv8 supports the creation, retrieval, and updating of Demand Gen campaigns using\n[Line Item](/display-video/api/structured-data-file/v8/LineItem), [Ad Group](/display-video/api/structured-data-file/v8/AdGroup), and [Ad](/display-video/api/structured-data-file/v8/AdGroupAd) files. Demand\nGen resources use different logic for timestamp verification, require the\npopulation of additional columns, and are limited by new restrictions across the\nthree file types.\n\n#### Timestamp verification\n\nFor all non-Demand-Gen line items, the `Timestamp` column of a [Line\nItem](/display-video/api/structured-data-file/v8/LineItem) file is populated at download with the last time a line item\nwas modified. This value is used when updating a line item using SDF to verify\nthat a line item has not been updated since the original file was downloaded. If\nso, the update fails.\n\nFor Demand Gen line items, the `Timestamp` column and the accompanying\nverification works differently. For Demand Gen line item entries, the column is\npopulated with the current time at download. On upload, Display \\& Video 360\nchecks if it has been more than 24 hours since the given timestamp. If it has\nbeen more than 24 hours, the original file entry is considered stale and the\nupdate fails. If this happens, download the file again and make your updates\nbased on the more recent version. *This new verification method does not prevent\nyou from overwriting changes made in the last 24 hours. To avoid accidental\noverwrites, only include Demand Gen line items that you want to update in files\nthat you upload.*\n\n#### Required columns\n\nThe following file types have columns that are now required for certain Demand\nGen resources, in addition to the columns that are required for all entities of\nthat file type.\n| **Note:** Other columns not listed here may be required when *updating* Demand Gen resources. See the v8 reference documentation for [Line Item](/display-video/api/structured-data-file/v8/LineItem), [Ad\n| Group](/display-video/api/structured-data-file/v8/AdGroup), and [Ad](/display-video/api/structured-data-file/v8/AdGroupAd) file types for an exhaustive list of requirements for each column.\n\n##### Line Item\n\n| Required columns for the following [Line Item](/display-video/api/structured-data-file/v8/LineItem) `Type` column values ||\n|------------|-----------------------------------------------------------------------------------------------------------------------------------------|\n| Demand Gen | |-------------------------------| | `Pacing Amount` | | `TrueView Bid Strategy Type` | | `TrueView Bid Strategy Value` | |\n\n##### Ad\n\n| Required columns for the following [Ad](/display-video/api/structured-data-file/v8/AdGroupAd) `Ad Type` column values ||\n|---------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| Demand Gen Carousel | |--------------------------| | `Business Name` | | `Call to Action` | | `Demand Gen Cards` | | `Description 1` | | `Headline` | | `In-feed Video Headline` | | `Landing Page URL` | | `Logo Asset IDs` | |\n| Demand Gen Image | |----------------------------| | `Business Name` | | `Call to Action` | | `Description 1` | | `Headline` | | `In-feed Video Headline` | | `Landing Page URL` | | `Logo Asset IDs` | | `Marketing Image Asset Id` | |\n| Demand Gen Product | |--------------------------| | `Business Name` | | `Description 1` | | `Headline` | | `In-feed Video Headline` | | `Landing Page URL` | | `Logo Asset IDs` | |\n| Demand Gen Video | |--------------------------| | `Business Name` | | `Call to Action` | | `Description 1` | | `Headline` | | `In-feed Video Headline` | | `Landing Page URL` | | `Logo Asset IDs` | | `Video Id` | |\n\n#### Updated restrictions\n\nIn addition to the new required columns for certain Demand Gen Line Items and\nAds, multiple columns across [Line Item](/display-video/api/structured-data-file/v8/LineItem), [Ad Group](/display-video/api/structured-data-file/v8/AdGroup), and\n[Ad](/display-video/api/structured-data-file/v8/AdGroupAd) file types have new use restrictions that apply to Demand Gen\nresources.\n\nThese restrictions are numerous and specific to the columns in question, so this\nguide doesn't provide an exhaustive list of restrictions. We recommend that you\nclosely read the v8 reference documentation for [Line Item](/display-video/api/structured-data-file/v8/LineItem), [Ad\nGroup](/display-video/api/structured-data-file/v8/AdGroup), and [Ad](/display-video/api/structured-data-file/v8/AdGroupAd) file types before creating or updating\nDemand Gen resources using SDF upload."]]
