Implementation of the COIN API?

  • A developer can immediately start working with the COIN API with help of clear documentation and sample codes
  • The COIN API is protected according to the latest security standards. Secure multi-factor authentication and encryption is used. This is done by means of Keyed Hash Message Authentication Code (HMAC) and signed JSON Web Token (JWT). You can manage these security methods yourself for your API connections via the COIN portal.
  • One function is called at a time. You will immediately receive a response in the form of a confirmation or error message.
