# I'm an app developer

> Routing page for partners building on the Sumvin Platform API.

You're building an app that creates Sumvin users, manages their wallets, runs them through <Tooltip headline="KYC" tip="Know Your Customer — identity verification that feeds attestation claims onto credentials." cta="Glossary →" href="/glossary">KYC</Tooltip>, and — optionally — runs <Tooltip headline="Errand" tip="An agent's scope-bound tasking run: Intent → Authorization → Vigilance." cta="Glossary →" href="/glossary">Errand</Tooltip>s or agent flows on their behalf. The **Platform API** is your primary surface.

## Start here

Read in this order:

1. **[Platform API quickstart](/quickstart)** — your first authenticated request.
2. **[Stand up an account](/guides/quickstarts/stand-up-account)** — bring a user online end-to-end: creation, onboarding, KYC, first wallet.
3. One of the product quickstarts, depending on what you're building:
   * [Errands](/guides/quickstarts/perpetual-search) for agentic shopping flows.
   * [On-ramp with Meld](/guides/quickstarts/onramp-meld) for fiat on/off-ramp.
   * [Issue a card](/guides/quickstarts/issue-card) for the wallet-funded card flow.
   * [Payment links](/guides/quickstarts/payment-link) for x402 payment link flows.

## Reference material you'll come back to

* [Onboarding guide](/guides/onboarding) — the state machine your users move through.
* [KYC guide](/guides/kyc) — identity-verification integration and attestation handling.
* [Wallets guide](/guides/wallets) — multi-chain wallets and Safe smart accounts.
* [Errand guide](/guides/ipa) — orchestrating in-product and agent-driven actions.
* [Scopes reference](/identity/scopes) — the capability envelope for PINTs.
* [Authentication](/authentication) — how your app authenticates against the Platform API.

## What to skip for now

* The **[Verifier Guide](/merchant/overview)** is for services that receive Sumvin credentials, not build them. Skip it unless you are also acting as a merchant.
* The **[SIS Dashboard](/dashboard/introduction)** is only relevant if you are operating a federated SIS integration — configuring your own auth provider, environments, and API keys.
