Creating a challenge by a third party

Hello

We are programming a bot on discord that performs various tasks to make it easier for us to discuss about chess on the server.
For instance, the bot is able to link a lichess username with a discord username, or show a gif of the last game played, so that we can comment on it or whatever.

Our next endeavor is for us to be able to challenge each other on lichess directly through discord.
The end goal here is that the following command :

.challenge 15+15

creates a challenge so that 2 players can just click on it and play.

Of course, the issue here is that the discord bot doens't have access to people's lichess account, and is therefore unable to create a challenge. This is why we need to create a lichess link for a game, but such that the 2 spots for the game are still available.
A work around that we thought about was to create 2 players tournaments, but the bot is only allowed too create 2 tournaments a day, which is clearly not sufficient.

Is there a way to do what we want? Or are we doomed to having to open our navigator, open lichess, and create the challenge oourselves?

Thank you :3

We have APIs to create and accept challenges https://lichess.org/api#operation/challengeCreate but they require oauth which I don't think you have, here.

I created a ticket about your use case https://github.com/ornicar/lila/issues/6390

@tacticalbert Could this also relate to https://lichess.org/forum/redirect/post/ib6Wvcvq
Could the 2 issues be addressed together maybe?

Thanks for the help, we indeed don't have auth.

It's already available for test on https://lichess.dev, will be deployed to lichess.org within a day or two. Ping @CathedraleEngloutie
