Claude Code

Use Claude Code to build Passage Connect integrations faster. The Passage Connect skill gives Claude full context on our API — endpoints, types, webhooks, and provider schemas — so it can write correct integration code without you having to explain the API.

Install the skill

Download the skill files into your Claude Code skills directory:


mkdir -p ~/.claude/skills/passage-connect-api/references
 
curl -sL https://docs.getpassage.ai/marketplace/SKILL.md \
  -o ~/.claude/skills/passage-connect-api/SKILL.md
 
curl -sL https://docs.getpassage.ai/marketplace/references/types.md \
  -o ~/.claude/skills/passage-connect-api/references/types.md

Or clone manually from the marketplace.json .

What it knows

Once installed, Claude Code automatically activates the skill when you mention Passage, account linking, webhooks, or any related concept. It has full context on:

All Connect API endpoints — POST /v1/links, GET /v1/links/:id, GET /v1/providers, etc.
Request and response types — exact shapes for every endpoint
Webhook format — ES256 JWT signing, link.complete/link.failed events, verification flow
Provider catalog — all integrations, resources, operations, argument schemas, and result schemas
Link state machine — pending → active → complete/failed/expired
Code patterns — TypeScript examples for creating links, polling, and handling webhooks

Example prompts

Try asking Claude Code things like:


Build a webhook handler for Passage Connect that verifies the ES256 signature
and stores completed link results in our Postgres database


Create a Passage link for reading T-Mobile payment methods and return the
app clip URL to the frontend


Add a /connect endpoint to our Express API that creates a Passage link,
returns the claim code, and polls for the result


Write a multi-operation Passage link that reads both payment methods and
billing statements from AT&T

Marketplace JSON
