# Register the Client 

We will need to generate access tokens in order to authenticate and CRM resources effectively. Please make sure to follow the steps listed below. 

1. Login to [Zoho's API Console](https://api-console.zoho.com/). Click **Self Client**.

4. The [Grant token](https://docs.catalyst.zoho.com/en/api/oauth2/generate-grant-token/#GenerateGrantToken) will be generated for the specified scopes. You can fetch the [Client ID](https://docs.catalyst.zoho.com/en/api/oauth2/register-new-client/) and [Client Secret](https://docs.catalyst.zoho.com/en/api/oauth2/register-new-client/) credentials from Client Secret tab. You will need to generate the access and refresh tokens by following the steps mentioned in [this page](https://docs.catalyst.zoho.com/en/api/oauth2/generate-access-and-refresh-token/#GenerateAccessandRefreshToken). 

> **Note:** Please make sure you save these credentials. We will be configuring these values as environmental variables to our function in [this step.](https://docs.catalyst.zoho.com/en/tutorials/ecommerce-bot/nodejs/deploy-to-console)
