Problem

We have a comprehensive integration guide in Notion ("Creating Payment Destinations and Payment Links with the Request Network API") that walks through the end-to-end flow: signing in via Dashboard, creating payment destinations, generating Client IDs, setting up webhooks, and creating payment links. However, this guide is only available internally in Notion.

Integration partners have run into problems because they don't have access to this documentation. New integrators face the same gap — they need to be given the Notion page manually rather than finding it in our public docs.

Proposed Solution

Formalize the Notion integration guide into mintlify-docs as a public-facing integration guide covering:

1. Sign in with wallet (Dashboard)
2. Create payment destination (Dashboard)
3. Create Client ID (Auth API)
4. Set up webhooks (Portal)
5. Create secure payment / payment link (Request API)
6. Check payment status (API or webhook)

Source material: Notion page — Creating Payment Destinations and Payment Links with the Request Network API

Considerations

• Webhook reference docs already exist in mintlify beta docs — this guide should link to them rather than duplicate
• Webhook E2E tests already exist in request-api — no additional testing needed
• The Notion page includes supported chains/tokens tables, troubleshooting, and webhook payload examples — all should be carried over
• Check if mintlify-docs has an existing "guides" or "quickstart" section where this fits
