Also I tried Typesense postman API, it's not working, as in I created an API key, and for url I used cluster's url...which is something like

<http://cluster.typesense.org/cluster|cluster.typesense.org/cluster> name

The cluster host name is Typesense cloud should be displayed in the dashboard after you've provisioned the cluster. It will be of the form xxx-1.a1.typesense.net. It's not the one in the address bar.

Okay great, I'll try it and let you know
