n8n Social Metrics Integration

I’m building a unified reporting flow inside n8n and I need an expert who can set up rock-solid credentials and HTTP Request nodes that pull post-level metrics for analytics from the main social and ad platforms my client uses (business / company accounts).

Scope
• Social sources: Facebook, Instagram, LinkedIn, TikTok and YouTube.
• Ad sources: Meta Ads, Google Ads and YouTube Ads.
• Metrics: views, engagement (likes, comments, shares), reach / impressions, follower growth, etc.

What I already have
An n8n instance running on my own server with generic webhook.

What I need from you
1. Proper OAuth or token-based credentials with required scopes for every platform mentioned above, created inside n8n’s Credentials section.
2. HTTP Request (or dedicated API) nodes that fetch analytics metrics reliably.

Acceptance criteria
• API rate limits, paging and token refresh are handled gracefully.
• Returned data contains the exact fields for views, engagement, reach / impressions, follower count per post or ad and similar analytics metrics.
• No hard-coded secrets; everything lives in n8n Credentials.

If you have recent, demonstrable experience with n8n, Graph API, TikTok API, LinkedIn API, YouTube Data API or Google Ads API, let’s talk—those real-world examples will weigh heavily in selection.
