# Custom service and auth FAQs

Common questions Tray customers ask about creating custom services and authentications for apps which are not in the Tray connector library

## What's the difference between a Service and an Authentication?

### Explanation

There are nuanced differences between a custom **Service** and an **Authentication** created using that service. At a high level:

* The auth **service** is really a custom template that you define **in order to create individual authentications**.
* An **authentication can then be instantiated using your pre-defined template** (the service).
* This arrangement allows you to create **multiple authentications** which fit an API authorization schema.
* However, \*\*each authentication API Key and Secret Key are unique to the individual authentication \*\*that you define rather than the auth service. Remember, the service is just the template.

## Why can't I can't find the custom services tab?

### Explanation

The services tab is not accessible from the organizations workspace. It is only available from your **personal workspace**.
Once you create a custom service in your personal workspace, you will be able to use it to create a new authentication in your organizations workspace.

Why can't I see the service I just created in my authentications?

### Explanation

It can take up to **5 minutes** for the new service to populate in the service drop-down when creating an authentication. If the new service still isn't showing up after 5 minutes, try a **hard refresh** of the workflow page.

You will not have a personal workspace if you are an embedded org owner. In that case, you can access Connector Builder in your embedded workspace.

## Is there an additional fee to access Connector Builder?

### Explanation

Connector Builder is part of our core product with no additional fees required.

## \*\*When to use the HTTP connector vs Connector Builder? \*\*

### Explanation

We recommend using the [HTTP client connector](https://tray.ai/documentation/connectors/core/http-client) when you are seeking to use a single endpoint which is not currently available within the service connector's operations list.
We recommend using [Connector Builder](https://tray.ai/documentation/platform/connectivity/connector-builder) if there is no Tray connector available for the service and you need to create a new connector with all the required operations and share it with other users within your organisation.
