# Using connector templates

> Create custom Integration Service connectors for AI Trust Layer LLM configurations using templates for AWS Bedrock, Azure OpenAI, and other providers.

Connector templates are predefined Integration Service connector configurations for common LLM providers. When you create a custom connector through AI Trust Layer, selecting a template pre-populates the connector with the required API resources, authentication setup, and JavaScript hooks for that provider, reducing manual configuration.

## Create a custom connector from a template

1. Navigate to **Admin** > **AI Trust Layer** > **LLM configurations** and select **Add configuration**.
2. Select the **Tenant**, **Product**, and **Feature** values for the configuration.
3. Under **Model Configuration**, configure the **LLM Name** and **API Type** fields.
4. In the **Connector** field, select **Create custom connector**.
5. In the **Create custom connector** dialog, select one of the available templates.
6. Select **Create connector**. You are redirected to Connector Builder, where you can edit the configuration, save it, and [publish the connector](https://docs.uipath.com/integration-service/automation-cloud/latest/user-guide/connector-builder-publishing).

### Result

The custom connector is created and pre-configured based on the selected template. You can edit the connector's JavaScript hooks to further customize the LLM request and response behavior.

## Available templates

The templates available in the **Create custom connector** dialog depend on the **API Type** you selected in the model configuration.

### AWS Bedrock

**Available for API type:** AWS Bedrock

**When to use:** Use this template when connecting to your own Amazon Bedrock LLM instance and you need to control or modify LLM request and response attributes.

**Authentication:** This template follows the standard [AWS Bedrock authentication](https://docs.uipath.com/integration-service/automation-cloud/latest/user-guide/uipath-aws-bedrock-authentication), based on API key.

### Azure OpenAI

**Available for API type:** OpenAI

**When to use:** Use this template when connecting to your own Azure OpenAI LLM instance and you need to control or modify LLM request and response attributes.

**Authentication:** This template follows the standard [Azure OpenAI authentication](https://docs.uipath.com/integration-service/automation-cloud/latest/user-guide/uipath-microsoft-azureopenai-authentication).

### Google Vertex AI

**When to use:** Use this template when connecting to your own Google Vertex AI LLM instance and you need to control or modify LLM request and response attributes.

**Authentication:** This template follows the standard [Google Vertex AI authentication](https://docs.uipath.com/integration-service/automation-cloud/latest/user-guide/uipath-google-vertex-authentication), based on API key.

### OpenAI V1 Compatible

**Available for API type:** OpenAI

**When to use:** Use this template when connecting to your own OpenAI or OpenAI V1 Compatible instance — for example, Fireworks — and you need to control or modify LLM request and response attributes.

**Authentication:** This template follows the standard [OpenAI V1 Compatible authentication](https://docs.uipath.com/integration-service/automation-cloud/latest/user-guide/uipath-openai-openaiv1compliant-authentication), based on API key.

### Custom AI Gateway

**Available for API type:** All

**When to use:** Use this template when your LLMs are behind an AI Gateway.

**Authentication:** For configuration details, refer to the [Connector Builder authentication documentation](https://docs.uipath.com/integration-service/automation-cloud/latest/user-guide/authentication-configuration).

The template includes two API resources required for the **Custom** authentication type:

- `/onProvision` — Called when the Integration Service connection is created. Fetches a temporary token from your Identity Provider and saves it on the connection together with an expiration time.
- `/onRefresh` — Used to refresh the token. The target URL, pre-request hook, and post-request hook must match those configured for `/onProvision`.

If you choose an authentication type other than **Custom**, remove the `/onRefresh` and `/onProvision` API resources from the connector.

## Edit the JavaScript hooks

After creating a connector from a template, you can customize its behavior by editing the pre-request and post-request JavaScript scripts. For an overview of Connector Builder, refer to the [Connector Builder documentation](https://docs.uipath.com/integration-service/automation-cloud/latest/user-guide/connector-builder-about).

:::note
Because this capability is generally available upon request, editing the scripts requires assistance from UiPath Support. Contact UiPath Support to enable and configure the JavaScript hooks for your connector.

Before editing the scripts, review the available code snippets and the documentation for each reserved keyword.
