## Brief description of issue
Mainly 404 links.
I'm just posting 2 pages, there is probably.

Start with docs/getting-started/02-register-app.md and docs/getting-started/07-workflow-guides.md, using the reported Adobe Stock API documentation URLs to locate the affected links. Check the Q&A anchor, API Key Integrations, use case matrix, Enterprise service account, and Affiliate workflow links. Done means the reported links resolve correctly and the Q&A link scrolls to its target.
