+### How to configure the OAuth credentials for the local environment?
+Twist doesn't accept the localhost callback  URL. However, you can follow the steps mentioned below to configure the OAuth credentials for the local environment:
+1. We will use [ngrok](https://ngrok.com/) to expose the local server running on port `5678` to the internet. In your terminal, run the following command:
+```sh
+ngrok http 5678
+```
+2. Run the following command in a new terminal. Replace `<YOUR-NGROK-URL>` with the URL that you get from the previous step.
+```sh
+export WEBHOOK_TUNNEL_URL=<YOUR-NGROK-URL>
+```
+3. Start your n8n instance.
+4. Follow the instructions mentioned in the [Using OAuth](#using-oauth) section to configure your credentials.
