Learn how to access your API keys for enhanced security when calling blockchain APIs.

Authentication in Overledger

Overledger APIs utilise the OAuth 2.0 authorisation via the machine-to-machine authorisation flow (Client-Credentials grant type) and short-lived JWT bearer tokens.

To generate JWT tokens, create a set of API keys by registering your application on Quant Connect.

API keys consist of your ClientID and Secret, allowing resource CRUD operations via the Overledger APIs.

Send an authentication request to the OAuth 2.0 authentication endpoint to retrieve a short-lived bearer token. When making API calls, provide the bearer token via the Authorisation header. The JWT token is valid for 1 hour.
