Insforge Integrations

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

Provider	Guide	When to use
Clerk	Clerk JWT Templates + InsForge RLS	Clerk signs tokens directly via JWT Template — no server-side signing needed
Auth0	Auth0 Actions + InsForge RLS	Auth0 uses a post-login Action to embed claims into the access token
WorkOS	WorkOS AuthKit + InsForge RLS	WorkOS AuthKit middleware + server-side JWT signing with jsonwebtoken
Kinde	Kinde + InsForge RLS	Kinde token customization for InsForge integration
Stytch	Stytch + InsForge RLS	Stytch session tokens for InsForge integration
Better Auth	Better Auth + InsForge RLS	Self-hosted auth running in your InsForge Postgres — no third-party SaaS, no per-MAU cost

Payment Facilitators

Provider	Guide	When to use
OKX x402	OKX as x402 facilitator (USDG on X Layer)	Pay-per-use HTTP endpoints settled onchain with zero gas for the payer

Common Patterns

Auth providers

1. Provider signs or issues a JWT containing the user's ID
2. JWT is passed to InsForge via accessToken in createClient() (deprecated alias: edgeFunctionToken)
3. InsForge exposes claims through auth.jwt() 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
• Better Auth — Self-hosted in your Postgres; no SaaS vendor; you own the user table. Pairs cleanly with InsForge's Postgres via a connection string + a small bridge route. Requires a one-time REVOKE after migrate to seal PostgREST exposure.

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
• Pass the JWT via accessToken — a static string, not a function; for short-lived tokens (Clerk) sync refreshes with client.setAccessToken(token, AuthChangeEvent.TOKEN_REFRESHED) after the initial same-user sign-in
• Always get the JWT secret via npx -y @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

Common Mistakes

Auth

Mistake	Solution
Using auth.uid() for RLS	Use requesting_user_id() — third-party IDs are strings, not UUIDs
Using UUID columns for user_id	Use TEXT — all supported providers use string-format IDs
Hardcoding the JWT secret	Always retrieve via npx -y @insforge/cli secrets get JWT_SECRET
Missing requesting_user_id() function	Must be created before RLS policies will work

Payments (x402)

Mistake	Solution
Using an OKX exchange trading API key	Create a separate Web3 API key at web3.okx.com/onchainos/dev-portal
Wrong EIP-712 domain values	Read the token contract's DOMAIN_SEPARATOR — for USDG on X Layer use name: "Global Dollar", version: "1"
Ignoring DB insert error after settlement	Always destructure { error } and log/handle it — money has already moved
MOCK_OKX_FACILITATOR=true in production	Mock mode is demo-only; it returns fake tx hashes and bypasses verification
