InsForge Integrations

This skill covers integrating third-party providers with InsForge. Currently two categories are supported: auth providers (RLS via JWT claims) and payment facilitators (x402 HTTP payment protocol). Each provider has its own guide under this directory.

Auth Providers

Payment Facilitators

Common Patterns

Auth providers

1. Provider signs or issues a JWT containing the user's ID
2. JWT is passed to InsForge via edgeFunctionToken in createClient()
3. InsForge extracts claims via request.jwt.claims in SQL
4. RLS policies use a requesting_user_id() function to enforce row-level security

Payment facilitators (x402)

1. Server returns 402 Payment Required with a JSON challenge base64-encoded in PAYMENT-REQUIRED header
2. Client signs an EIP-3009 authorization using the stablecoin's EIP-712 domain
3. Server forwards the signed payload to the facilitator's /verify + /settle endpoints
4. Server records the settled payment in an InsForge table with a realtime trigger for live dashboards

Choosing a Provider

Auth

• Clerk — Simplest setup; JWT Template handles signing, no server code needed
• Auth0 — Flexible; uses post-login Actions for claim injection
• WorkOS — Enterprise-focused; AuthKit middleware + server-side JWT signing
• Kinde — Developer-friendly; built-in token customization
• Stytch — API-first; session-based token flow

Payment facilitators

• OKX x402 — Onchain pay-per-use via USDG on X Layer; zero gas for the payer

Setup

1. Identify which provider the project uses
2. Read the corresponding reference guide from the tables above
3. Follow the provider-specific setup steps

Usage Examples

Each provider guide includes full code examples for:

• Provider dashboard configuration (API keys, application settings, etc.)
• Server and client code (JWT utilities for auth; facilitator client + signing utilities for payments)
• Database setup (RLS for auth; payment table + realtime trigger for payments)
• Environment variable setup

Refer to the specific references/<provider>.md file for complete examples.

Best Practices

Auth

• All auth provider user IDs are strings (not UUIDs) — always use TEXT columns for user_id
• Use requesting_user_id() instead of auth.uid() for RLS policies
• Set edgeFunctionToken as an async function (Clerk) or server-signed JWT (Auth0, WorkOS, Kinde, Stytch)
• Always get the JWT secret via npx @insforge/cli secrets get JWT_SECRET

Payment facilitators (x402)

• Always check the result of the database insert(...) after settlement — settlement takes money onchain before the insert runs; a silent DB failure loses the record
• Add UNIQUE to the tx_hash column to prevent duplicate records from retries
• Verify EIP-712 domain (name, version) against the token contract's on-chain DOMAIN_SEPARATOR — wrong values produce Invalid Authority errors
• Use a MOCK_OKX_FACILITATOR env flag for local dev so the full flow can be exercised without real funds
