Quickstart

Use this section to move from setup to a working integration path as quickly as possible.

Start with Initial Setup. It consolidates the environment choice, credential checklist, JWT generation, DigitalSignature context, and webhook preparation into one onboarding path.

Before your first request

Make sure you already have:

  • Your ApplicationToken
  • Your CryptoToken for DigitalSignature on sensitive operations
  • A publicly accessible webhook endpoint
  • A staging-safe order or wallet reference for your first tests

ℹ️ Staging environment: All quickstarts use https://api.homologacao.connectpsp.com. Transactions in staging use test values and do not move real funds.
