# Using Bware Labs Endpoint in PolkadotJs
The following steps describe how you can use your own endpoint, generated on [app.bwarelabs.com, ](https://app.bwarelabs.com)in the Polkadot.js GUI. The flow below, applies to any of the substrate based networks supported by our platform but for the purpose of this example we will use Astar Tesnet (Dusty)
In order to use your endpoint within Polkadot.Js you will need to generate one first by following the steps from this [tutorial](https://app.gitbook.com/@bwarelabs/s/bware-docs/~/drafts/-MaWxwCEQVixpsNL9NMV/bware-labs-platform-tutorial-1). Once the endpoint is generated and running, copy the WebSocket endpoint as seen in the image below:
Next, go to and expand the menu on the upper left corner as follows:
Select the development section and find the "Custom endpoint" text input:
Add you custom endpoint instead of the official polkadot one, click the "Save" icon, and that's it, you're good to go.
