I'm working on an Eikon add-on (desktop, thick client) that uses AAA to log in and entitle users. We're transitioning some of our services to the Elektron Data Platform which requires an OAuth2 token. We want to use the iPlanetDirectoryPro cookie/token which was created when the user previously logged in. In reading the API documentation it looks like Implicit Grant is what we want (https://developers.refinitiv.com/article/oauth-grant-types-elektron-data-platform) but I haven't been able to find an example of exactly what I'm trying to do.
The auth/oath2/v1/authorize endpoint will take an iPDP cookie but requires a redirect URL to handle extracting the token. We're a desktop app so we can't provide that. The auth/oath2/v1/token endpoint will return a token but requires a username and password. Is there an endpoint that will take an iPDP cookie and return a token?
