Have you created your connector? Start using the Nylas Sandbox | Nylas Docs

Also, here’s a Microsoft guide on our docs Use Microsoft accounts and data with Nylas | Nylas Docs

i m following this guide Create grants with OAuth and an API key | Nylas Docs and this video https://www.youtube.com/watch?v=8luB4dJggtI&list=PLk-4iahO3b-xd42-RL4DJQyuEoFFYwTbC&index=80

I see…I did followed the video as well :sweat_smile: although it worked for me…could you post your source code? No need to post any keys obviously…just want to see what’s going wrong…which SDK are you using?

yess, of course! this code: interface AuthInNylasToGetGrantIdProps {

urlCallback: string;
provider?: “google” | “microsoft”;
}
export const authInNylasToGetGrantId = async ({
urlCallback,
provider = “google”,
}: AuthInNylasToGetGrantIdProps) => {
const config = {
clientId: nylasConfigValidated.clientId,
callbackUri: urlCallback,
apiKey: nylasConfigValidated.apiKey,
apiUri: “https://api.us.nylas.com”,
};
const nylas = new Nylas({
apiKey: config.apiKey,
apiUri: config.apiUri,
});

const authUrl = nylas.auth.urlForOAuth2({
clientId: config.clientId,
provider,
redirectUri: config.callbackUri,
state: provider,
});

return { url: authUrl };
};

A couple of things…if you’re using Microsoft, you should mention Google at all…

Have you registered your callbackUri on the dashboard?

Otherwise, I don’t anything wrong with your code :thinking:
