Access control

It is common for multiple team members to collaborate on building an agent. Using roles, you can control access and permissions granted to team members.

You can configure access using the Dialogflow CX Console (visit documentation, open console) or by using the Google Cloud console (visit documentation, open console) with Identity and Access Management (IAM). The Google Cloud console is used to grant IAM roles to principals, while the Dialogflow Console is used to grant Dialogflow agent roles to principals. Dialogflow agent roles are convenient predefined roles defined by Dialogflow that restrict access to one agent or the child resources of a specific agent.

There are some situations in which you must use the Google Cloud console:

• IAM Project Owner role is by default granted to the user that created the project that owns the agent. This owner has full access to all agents in the project. If you want to change the project owner, you need to use the Google Cloud console.
• Only agent-level access can be configured through the Dialogflow CX Console. If you want to configure project-level access, you need to use the Google Cloud console.
• A subset of IAM roles have corresponding Dialogflow agent roles. If you want to grant a project-level or agent-level role that does not exist on the Dialogflow CX Console, you need to use the Google Cloud console.

If you are using the API, you may also have one or more applications that send requests to an agent. In this case, you can control access with service accounts.

Control access with the Dialogflow CX Console

The Dialogflow CX Console allows you to apply convenient agent roles configured for agent-level sharing. These roles correlate to IAM roles with IAM conditions that limit access to the specific agent or a subset of child resources of the agent.

To access agent roles configuration from the Dialogflow CX Console, you must be granted the Project IAM Admin role for the associated project. This role is granted from the Google Cloud console.

Note: The Dialogflow CX Console will only show principals with these specific roles and agent-specific conditions. If you have used the Google Cloud console to add principals with any roles or conditions, they will not appear in the Dialogflow CX Console.

Sharing options are found in the agent's settings. To open the agent sharing settings:

1. Open the Dialogflow CX Console.
2. Choose your Google Cloud project.
3. Select your agent.
4. Click Agent Settings.
5. Click the Share tab.

Add a principal

1. Click Add.
2. Enter the email address for the user, group or service account.
3. Select User, Group or Service Account for the email type.
4. The Dialogflow Reader role is added by default, which is required for the users to access the Dialogflow CX Console.
5. Click Add role under Assign roles.
6. Select a role type under Type.
7. For the Flow Editor and Environment Editor roles, select specific flows or environments or keep the default All option.
8. Optionally, set the expiration date for the role.
9. Click Save.

Change principal roles

1. Click the principal in the list.
2. Update roles for this principal in the pop-up.
3. Click Save.

Remove a principal

1. Find the principal in the list.
2. Click the delete button for the principal.
3. Click Ok.

Note: After you apply principal role changes, there may be a delay before the changes take effect.

Control access with the Google Cloud console

You can control access with IAM settings. See the IAM quickstart for detailed instructions on adding, editing, and removing permissions.

To access the settings below, open the IAM page in the Google Cloud console.

Add a user or service account to the project

You can provide permissions to either users or service accounts by granting them roles on your Cloud project. Users are added by providing their email address. Service accounts are also added by providing their associated email address. You need to add service accounts when you want to use one service account for multiple projects. To find the email address associated with your service account, see the IAM Service Accounts page in the Google Cloud console.

To add a principal:

1. Click the add button at the top of the page.
2. Enter the principal's email address.
3. Select a role.
4. Click Save.

Change permissions

1. Click the edit button for the principal.
2. Select a different role.
3. Click Save.

Remove a principal

1. Click the delete button for the principal.

Add a condition to restrict access to one agent

When adding or editing a principal, you can create an IAM condition that restricts access to one agent.

Note: Please grant agent roles to user emails for CX console access directly in the Dialogflow CX console.

For example:

{
    "expression": "resource.name.startsWith(\"projects/PROJECT_ID/locations/REGION_ID/agents/AGENT_ID\")",
    "title": "For Dialogflow Agent AGENT_ID"
}

This condition gives you basic access to a specific agent. For example, a service account with this condition can only call the Dialogflow API to access the agent specified in the condition for the project, but not other agents in the project.

To add this condition to a role granted to a principal:

1. Select a principal.
2. Click the edit button for the principal.
3. Click Add condition.
4. In the Title field, enter For Dialogflow Agent AGENT_ID and replace AGENT_ID with your agent ID.
5. You may add any description.
6. Select the Condition Editor to create your condition.
7. Add the expression resource.name.startsWith("projects/PROJECT_ID/locations/REGION_ID/agents/AGENT_ID"), replacing AGENT_ID with your agent ID and PROJECT_ID with your project ID.
8. Click Save.

IAM roles

The following table lists common IAM roles relevant to Dialogflow CX. Permission summaries in the table use the following terms:

• Full access: Permission to modify access, create, delete, edit, and read any resource.
• Edit access: Permission to create, delete, edit, and read any resource.
• Session access: Permission to call methods for runtime-only resources during a conversation like detecting intent, updating context, updating session entities, or Agent Assist conversation interactions.
• Read access: Permission to read any resource.

Note: In order to modify access for an agent, you need a role that provides full access to the agent. In order to delete an agent, you need a role that provides full access or edit access to the agent.

Note: The console simulator calls the detectIntent API method during a conversation. This method performs a write on the session state. In order to use the console or call the API's detectIntent/streamingDetectIntent methods, you need a role that provides full access, edit access, or session access.

OAuth

If you are using Google client libraries to access Dialogflow, you do not need to use OAuth directly, because these libraries handle the implementation for you. However, if you are implementing your own client, you may need to implement your own OAuth flow. Access to the Dialogflow API requires one of the following OAuth scopes:

• https://www.googleapis.com/auth/cloud-platform (access to all project resources)
• https://www.googleapis.com/auth/dialogflow (access to Dialogflow resources)

Requests that involve Cloud Storage access

Some Dialogflow requests access objects in Cloud Storage for reading or writing data. When you call one of these requests, Dialogflow accesses the Cloud Storage data on the caller's behalf. This means that your request authentication must have permissions to access Dialogflow as well as the Cloud Storage objects.

When using a Google client library and IAM roles, see the Cloud Storage access control guide for information on Cloud Storage roles.

When implementing your own client and using OAuth, you must use the following OAuth scope:

• https://www.googleapis.com/auth/cloud-platform (access to all project resources)
