Hi all! I’m scoping an n8n workflow for a client (a listed company doing investor relations for retail investors) and would love input from anyone who has built something similar.

The idea: when the company publishes a press release, Claude drafts 3 to 5 ad variants, a human approves them in Slack, and n8n creates the ads via the Meta Ads API (and later Google Ads and LinkedIn). A daily job pulls performance data and flags or pauses weak ads.

A few questions:

API access: How long did it take you to get approved for the Google Ads developer token and the LinkedIn Marketing API? Any tips for getting through the application?

Meta Marketing API: Did you build directly against the API with HTTP requests, or use a community node? Any surprises with app review, permissions or token expiry?

Financial ads: Has anyone run ads for a listed company or a financial topic? Did you hit special ad categories, advertiser verification or rejections?

Automated optimisation: Do you let the workflow change budgets or pause ads on its own, or only flag them for a human? With small budgets I’m worried about resetting Meta’s learning phase.

Creating vs managing: Is it worth creating ads via API at all, or is it smarter to create them manually and only use the API for reporting?🙏
