Pre-requisites

NOTE: When using the production environment (app.hel.io), set your API endpoint to api.hel.io/v1 and generate API keys there. For the development environment, use api.dev.hel.io/v1 and generate API keys from app.dev.hel.io.
In order to perform actions using our API, you need to complete the following steps.

​
1. Create your Account & get API keys

  • Go to our dashboard and log in.
  • Under Developer -> API, check Enable to generate your Public and Secret API Keys.
  • Save these securely, as the Secret API Key won’t be retrievable later (you can regenerate both if needed).

Prepare Request Payload for paylinkId

When creating a Pay Link via API, you’ll need to specify the recipient wallet, payment currency, and accepted recipient currencies — so it’s important to gather this information beforehand. Here’s how to do it.
JSON
"recipients": [
    {
      "walletId": "YOUR_WALLET_ID",
      "currencyId": "6340313846e4f91b8abc519b"
    }
  ]

​
1. Retrieving your Wallet ID

You can retrieve your Wallet ID in one of the following ways:

​
Option 1: Via the Dashboard

  • Navigate to the Helio Dashboard
  • Go to Settings → Wallets
  • Click the three dots next to your wallet and select Copy wallet ID
Note: The Helio ID is different from your wallet’s public key.

​
Option 2: Via the API

  • Call the Get wallets endpoint
  • Use the id field from the wallet object returned in the response

​
2. Retrieving the Currency Id
