Google Ads API use case
This page documents the business purpose, workflow, users and data-handling practices of the internal Google Ads API tool operated by Asier González in Spain.
Business and purpose
I operate a small independent digital-commerce and automation practice. The tool is an internal decision-support application used to audit aggregate search demand before deciding whether to build or advertise a product or service.
One current validation project is a proposed service that converts batches of invoice PDFs into structured Excel data. Its transparent pilot page is available at Facturas PDF a Excel. The API analysis is a research gate; it does not prove demand and does not automatically launch advertising.
Intended users and access
The only user is Asier González. The tool is not sold, licensed or exposed to clients or the public. It accesses only Google Ads accounts that I own and administer.
- Manager account: 697-187-4800
- Linked advertiser account: 810-774-8201
API workflow
- A local CSV contains seed phrases for potential products and services.
- The application authenticates through OAuth 2.0 using a dedicated desktop client.
- KeywordPlanIdeaService GenerateKeywordIdeas is called for Spain and Spanish targeting.
- The tool stores aggregate keyword text, average monthly searches, competition and bid-range metrics in a local CSV.
- A local report ranks themes to support a go or no-go decision.
No campaigns, ads, bids, budgets or conversions are created or modified by this workflow.
Data handling and security
OAuth credentials, refresh tokens and the developer token are stored locally in a restricted credentials directory and are not committed to source control. API output contains aggregate keyword-planning metrics only. It is retained locally for internal analysis.
The tool does not access personal customer data and does not sell, share or use API data to profile individuals. Access can be revoked from the relevant Google account or Google Ads account.
Operations and compliance
Calls are made on demand at low volume using the official Google Ads API client library. The tool handles API errors, respects quotas and will be maintained as API versions change. If the use case expands to external users or account-management automation, the access request and public documentation will be updated before deployment.
