Thank you, I redirected the requests to the apiDomain. But this makes it easier for future. Apologies for the late reply. > - Is this the sub domain of your API's sub domain? Or is it a totally different API domain? This was for the apiDomain itself. > - Have you correctly configured CORS for this domain? The CORS is same for every requests, the cookies were getting attached to other requests but not these. I just imported Session in the component and obtained the userId in the frontend. Odd thing that happened was how just getting the userId in the component using

getUserId()

solved the issue. I didn't even use the userId in the request itself but the cookies started getting attached with the request. > Is this domain https, and is the secure flag in cookies https? Yes, https. > - Is there any output on the browser console when querying this domain? No there wasn't. I will check once again and let you know. > - What is the status code output of the API when you query? 200? 401? I was trying to obtain the userId in the backend and was returning an error status of 404 if the userId was null.
