There are three ways to retrieve entities and reporting data with Google Ads API.
- Using GET requests
- Using
GoogleAdsService.Search - Using
GoogleAdsService.SearchStream
This guide primarily focuses on streaming data from
GoogleAdsService. Here are high-level distinctions
for the three data retrieval methods:
| GET requests | GoogleAdsService.Search | GoogleAdsService.SearchStream | |
|---|---|---|---|
| Suitable for production code | No, debugging only | Yes | Yes |
| Service | Resource specific services (e.g., CampaignService) |
GoogleAdsService |
GoogleAdsService |
| Scenario | Fetching objects | Fetching objects and reports | Fetching objects and reports |
| Response | One object (e.g., Campaign) |
Pages of GoogleAdsRow objects |
Stream of GoogleAdsRow objects |
| Response's fields | All fields populated | Only those specified in the query | Only those specified in the query |
| Daily limits | 1,000 requests per day | Daily limits based on access levels | Daily limits based on access levels |
Search versus SearchStream
While Search may send multiple paginated
requests to download the entire report,
SearchStream sends a single request
and initiates a persistent connection with the Google Ads API regardless of the report
size. Packets of data will start to download immediately while the entire
remaining result is cached in a data buffer. Your code can start reading the
buffered data without waiting for the entire stream to finish. By eliminating
the round-trip network time required to request each individual page of a
Search response, depending on your
application, SearchStream may offer
improved performance over paging. This advantage becomes more apparent as
reports grow much larger. Here is an example to show the internal mechanics
between the two mechanisms:
| Search | SearchStream | |
|---|---|---|
| Report size | 100,000 rows | 100,000 rows |
| Page Size | 10,000 rows per page | Not Applicable |
| Number of API requests | 10 requests | 1 request |
| Number of API responses | 10 responses | 1 continuous stream |
You are also likely to get the first set of results faster with streaming, since
Search initially caches the entire result
set before sending the first page over to the client.
If you have an app that requires paging,
Search may be a better choice since it does
not require downloading the entire result set, while streaming would require
downloading it entirely. Also, if a stream is interrupted or experiences a
failure in the middle of a download, your platform would have to restart the
entire download again from the beginning.
Rate limit
Daily limits with both Search and
SearchStream adhere to the standard
limits and access levels of your developer token. A
single query or report using either Search or SearchStream is counted as one
operation, irrespective if the result is paged or streamed.
