Anda dapat menggunakan GoogleAdsFieldService
untuk meminta katalog secara dinamis untuk resource, kolom resource,
kunci segmentasi, dan metrik yang tersedia di metode
GoogleAdsServiceSearch dan
SearchStream. Katalog menyediakan metadata yang dapat digunakan oleh
klien Google Ads API untuk validasi dan pembuatan pernyataan Bahasa Kueri Google Ads.
Contoh permintaan dan respons HTTP
Permintaan terdiri dari HTTP GET ke server Google Ads API di URL berikut:
Resource yang dapat digabungkan secara implisit ke resource dalam klausa FROM.
metrics
Metrik yang tersedia untuk dipilih dengan resource dalam klausa FROM. Hanya diisi untuk kolom yang category-nya adalah RESOURCE.
segments
Kunci segmen
yang dapat dipilih dengan resource dalam klausa FROM.
Segmen ini membagi metrik yang ditentukan dalam kueri. Hanya diisi untuk kolom
dengan category adalah RESOURCE.
selectableWith
Kolom yang dapat dipilih bersama kolom tertentu, jika tidak ada dalam klausa FROM. Atribut ini hanya relevan saat mengidentifikasi resource atau segmen yang dapat dipilih dalam kueri yang tidak disertakan oleh resource dalam klausa FROM. Sebagai contoh, jika kita memilih ad_group.id dan segments.date dari ad_group, dan kita ingin menyertakan atribut dari campaign, kita perlu memeriksa apakah segments.date ada di atribut selectableWith untuk kampanye, karena dipilih bersama dengan kolom segments.date yang ada.

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`."]]
