Postman is a widely used tool for developing and testing APIs. You can use the Postman collection below to test the CryptoProcessing API in the sandbox environment. Download the Postman collection When you click the link, the JSON file opens in a new browser tab rather than downloading automatically. Save it to your computer, then import it into Postman. After importing it, open the SandBox API Collection variables and enter:
  • your API key in the key-v2 field
  • your secret key in the secret-v2 field
Once these values are set, you can start sending requests.
