{% hint style="info" %}
You can use the same account that you use to access Coherent Spark. The Coherent Assistant uses the same means of authentication to our Software as a Service (SaaS) offering.
{% endhint %}

### Where is my Spark URL?

Spark URL is the domain you use to reach Spark on the Web (can also use any URL from Spark once you've logged in) or the endpoint URL of any service you have on Spark.

{% hint style="info" %}
The Spark URL has the following syntax:

`https://spark.[environment].[region].coherent.global/[tenant]`
{% endhint %}

### I am getting an error: Invalid parameter, redirect\_uri

This error occurs when attempting to connect to a Spark environment not supported by Coherent Assistant. Please ensure you are using either UAT or PROD environments to log in.
