To authenticate with LogTrade IoL, your application must use bearer authentication. Bearer authentication is an authentication scheme using cryptic strings called bearer tokens. Bearer tokens are generated by the IoL account administrator from the IoL administration GUI, available at https://iol.logtrade.org:
API clients must attach this token to the Authorization header when making requests. Use the refresh token to generate a new API token before it expires. Read the Authentication section of the API Reference Guide for more details.
LogTrade only supports HTTPS for security reasons.
