This markdown guide is purpose-aligned, but users should review it carefully because its runnable examples can create wallets, escrows, payments, disputes, and other live account changes while the setup text understates the credential and sandbox requirements.
Install only if you intend to build against GreenHelix and are prepared to review examples before running them. Use a sandbox or least-privilege test API key, confirm the endpoint is non-production, set budget limits and approval gates, and do not run wallet, escrow, payment, dispute, or bootstrap examples against a live account without human review.
