First, register and sign in to the Element Pay console.
  • Console (Sandbox): https://console.elementpay.dev
  • Console (Production): https://console.elementpay.com

​
Environments

  • Sandbox: for development/testing, uses testnet tokens and may refund payments automatically.
  • Production: for live transactions.

​
Create an API key

  1. In the console, create an API key (start with Sandbox).
  2. Configure your Webhook URL and Webhook Secret on the key.
  3. Copy your Base URL for the environment you’re targeting.
Base URLs:
  • Sandbox: https://sandbox.elementpay.net/api/v1
  • Production: https://api.elementpay.net/api/v1

​
What an API key stores

  • Webhook URL + Secret (used to sign webhook events)
  • Environment binding (sandbox or production)

​
Authentication

Send your key in every request: 
X-API-Key: <key>

​
Tips

Keep separate keys for sandbox vs production. Rotate keys regularly and restrict who can view them.
