🔑Helio API key

Developer documentation for various Helio integration options

The Helio API allows you to integrate Helio checkouts into your app or payments flow. We offer API endpoints on both dev and mainnet.

• api.dev.hel.io/v1

• api.hel.io/v1/

How do I generate API keys?

Simply log in to the Helio dashboard --> Settings --> API. That's it!

IMPORTANT: If you use the Solana Pay plug-in for Shopify, you must first "link" a wallet in Settings -> Manage Wallets before you can generate an API key

Once you have your API keys, you can get started with your Helio integrations.

• Embed the Helio Checkout Widget in your app

• Create Pay Links via the API

• Create Charges: single-use checkout pages from a single PayID

• Confirm transactions via Webhooks
