Developer Tools

Bolta provides a range of developer tools for fast and convenient API integration.

API documentation

Detailed documentation for every endpoint, along with code samples in multiple programming languages. Supported languages: Shell, HTTP, JavaScript, Ruby, Python, PHP, Java, Go

Sandbox environment

Test the API freely in an environment that offers the same functionality as production.
  • Test keys (test_ prefix): Every issuance request is processed virtually. You can validate your integration logic without any actual transmission to the NTS.
  • Live keys (live_ prefix): These operate in the production environment, and issuance requests are actually transmitted to the NTS.
You can create test keys and live keys under Developer Center > API Keys.

Logging

Track API calls and webhook activity to support debugging.
  • Webhook logs: Monitor the delivery history of events such as issuance completion and failure.
For webhook setup, see the Webhook connection guide, and for checking logs, see the Webhook logs guide.
