GoogleAdsFieldServiceGoogleAdsServiceSearch ve
SearchStream yöntemlerinde kullanılabilen kaynaklar, kaynak alanları, segmentasyon anahtarları ve metrikler için kataloğu dinamik olarak istemek üzere kullanabilirsiniz. Katalog, Google Ads API istemcileri tarafından Google Ads sorgu dili ifadelerinin doğrulanması ve oluşturulması için kullanılabilecek meta veriler sağlar.
Örnek HTTP isteği ve yanıtı
İstek, aşağıdaki URL'de Google Ads API sunucusuna gönderilen bir HTTP GET işleminden oluşur:
Koşuldaki kaynağa örtülü olarak birleştirilebilen kaynaklar.FROM
metrics
FROM
Yan tümcesinde kaynakla birlikte seçilebilecek metrikler. Yalnızca category değerinin RESOURCE olduğu alanlar için doldurulur.
segments
FROM ifadesinde kaynakla birlikte seçilebilen segment anahtarları.
Bunlar, sorguda belirtilen metrikleri segmentlere ayırır. Yalnızca category değerinin RESOURCE olduğu alanlar için doldurulur.
selectableWith
Bir alanla birlikte seçilebilen alanlar (FROM
yan tümcesinde olmadığında). Bu özellik yalnızca FROM ifadesindeki kaynak tarafından dahil edilmedikleri bir sorguda seçilebilen kaynakları veya segmentleri tanımlarken geçerlidir. Örneğin, ad_group öğesinden ad_group.id ve segments.date öğelerini seçiyorsak ve campaign öğesindeki özellikleri dahil etmek istiyorsak segments.date öğesi mevcut segments.date alanı ile birlikte seçildiğinden segments.date öğesinin kampanya için selectableWith özelliğinde olduğunu kontrol etmemiz gerekir.
Meta veri ayrıntıları
Şu düzeylerde GoogleAdsFieldService simgesini kullanarak kataloğu isteyebilirsiniz:
Kaynak
Örneğin, googleAdsFields/campaign.
Kaynağın alanı
Örneğin, googleAdsFields/campaign.name.
Segmentasyon alanı
Örneğin, googleAdsFields/segments.ad_network_type.

The catalog provides metadata that can be used by\nGoogle Ads API clients for validation and construction of Google Ads Query Language statements.\n\nSample HTTP request and response\n--------------------------------\n\n| **Note:** The example shows the underlying HTTP/JSON request as a guide, but you are strongly encouraged to use one of the [client libraries](/google-ads/api/docs/client-libs) based on [gRPC](//grpc.io) to submit your requests.\n\nThe request consists of an `HTTP GET` to the Google Ads API server at the following\nURL: \n\n https://googleads.googleapis.com/v21/googleAdsFields/{resource_or_field}\n\nThe following example shows a request followed by the response returned from\n`GoogleAdsFieldService` for the **ad_group** resource:\n\n### Request\n\n https://googleads.googleapis.com/v21/googleAdsFields/ad_group\n\n### Response\n\n {\n \"resourceName\": \"googleAdsFields/ad_group\",\n \"name\": \"ad_group\",\n \"category\": \"RESOURCE\",\n \"selectable\": false,\n \"filterable\": false,\n \"sortable\": false,\n \"selectableWith\": [\n \"campaign\",\n \"customer\",\n \"metrics.average_cpc\",\n \"segments.device\",\n ...\n ],\n \"attributeResources\": [\n \"customer\",\n \"campaign\"\n ],\n\n \"metrics\": [\n \"metrics.conversions\",\n \"metrics.search_budget_lost_impression_share\",\n \"metrics.average_cost\",\n \"metrics.clicks\",\n ...\n ],\n \"segments\": [\n \"segments.date\",\n \"segments.ad_network_type\",\n \"segments.device\",\n ...\n ]\n }\n\nFor this example, the important arrays are:\n\n`attributeResources`\n: Resources that can be implicitly joined to the resource in the `FROM`\n clause.\n\n`metrics`\n: Metrics that are available to be selected with the resource in the `FROM`\n clause. Only populated for fields where the `category` is `RESOURCE`.\n\n`segments`\n: Segment keys that can be selected with the resource in the `FROM` clause.\n These segment the metrics specified in the query. Only populated for fields\n where the `category` is `RESOURCE`.\n\n`selectableWith`\n\n: Fields that can be selected alongside a given field, when not in the `FROM`\n clause. This attribute is only relevant when identifying resources or segments\n that are able to be selected in a query where they are not included by the\n resource in the `FROM` clause. As an example, if we are selecting `ad_group.id`\n and `segments.date` from `ad_group`, and we want to include attributes from\n `campaign`, we would need to check that `segments.date` is in the\n `selectableWith` attribute for campaign, since it's being selected alongside\n the existing `segments.date` field.\n\nMetadata details\n----------------\n\nYou can request the catalog using the `GoogleAdsFieldService` at these levels:\n\nResource\n: For example, `googleAdsFields/campaign`.\n\nResource's field\n: For example, `googleAdsFields/campaign.name`.\n\nSegmentation field\n: For example, `googleAdsFields/segments.ad_network_type`.\n\nMetric\n: For example, `googleAdsFields/metrics.clicks`."]]
