Add user-driven steps, tasks, and approvals to workflows
User Tasks enable you to build workflows that require a user to take action before the workflow proceeds. The User Task block pauses a workflow and creates a user task within the organization. Users then review and action tasks using Retool apps. Only when a user submits task completion using a Retool app does the workflow containing the user task block resume.
Workflows containing a User Task block provide context data for a user task which is accessible from the Retool app. When actioned, the user task can provide output data back to the workflow.
Create user tasks from a workflow
User groups assigned to a user task must also have use access to the associated app where the user tasks are exposed to users. If not, users cannot use the app to complete user tasks.
To create user tasks, add the User Task block to the control flow of a workflow. You then configure the following block fields:
Setting | Description |
---|---|
Assign To | The users or groups that can action user tasks created by this workflow. |
App | The Retool app with which to review and action tasks. |
Task Context | Additional data from the workflow to include with the user task. |
Expiry Time (days) | The length of time after which the task expires. |
All user tasks initially have status
of pending
. This changes to submitted
once a user actions the task. When the User Task block runs, no further blocks along the control flow run until the task is actioned.
Set user task assignments
User task permissions are optional. If unset, any user in the organization can view and action the user task.
You can specify which users and permission groups are allowed to action tasks created by the User Task block. This is useful for restricting processes to a particular set of users, such as only allowing the finance team to administer refund requests.
You can also dynamically assign user tasks to users and groups using conditional logic. Click for the Assignments field and then specify custom JavaScript logic to dynamically evaluate assignments.
If your organization uses Source Control and has multiple instances of self-hosted Retool, ensure that user emails and group names are the same across instances.
When dynamically assigning tasks, the Assignments field expects an assignment
object with the following properties.
- User assignment
- Group assignment
email
The email address.
name
The user name.
type
The assignment type.
Values
user | The user to assign. |
group | The group to assign. |
The retoolContext global object contains groups
and users
properties with the necessary information.
if (getCaseload.data >= 5) {
return retoolContext.users['jenny@example.com']
} else {
return retoolContext.users['admin@example.com']
}
name
The group name.
type
The assignment type.
Values
user | The user to assign. |
group | The group to assign. |
The retoolContext global object contains groups
and users
properties with the necessary information.
if (getCaseload.data >= 5) {
return retoolContext.groups['Operations']
} else {
return retoolContext.groups['Escalation Team']
}
You can also use a combination of users and groups when determining assignment.
if (getCaseload.data >= 5) {
return [retoolContext.users['jenny@example.com'], retoolContext.groups['Operations']]
} else {
return [retoolContext.users['admin@example.com'],retoolContext.groups['Escalation Team']
}
Create the user tasks app
Workflows that create user tasks and their associated apps must both use the same permission groups. If not, users cannot use the app to action user tasks.
You create a Retool app from the User Task block for users to action tasks. Once you add a User Task block, click Create User Task to create a task review app using the default template. This starter app includes basic functionality for managing user tasks. If you have Edit or Own permissions to app folders, you can create your app within any of those folders. The app inherits any folder-level permissions, if set.
You can run the User Task block as you build and test your workflow. When manually run, the Workflow:
- Displays a modal in the Workflows IDE that contains the Retool app.
- Creates a test user task for testing the workflow and app whilst it runs.
Provide task context
The User Task block can include additional data to use as context for the user task (e.g., order details). You can reference this data within Retool apps from a task's context.result.data
property to populate component values, reference in queries, etc.
Task context is evaluated as JavaScript and must either reference or return a valid value (e.g., startTrigger.data
).
Set task expiration
Use the Expiry Time field to specify length of time, in days, after which the task automatically expires. If no value is provided, the task does not expire. When a task expires, its status
automatically updates to expired
. Use integer or float numbers to specify the duration, such as 1
or 1.5
.
After the task runs, you can reference the expiryMetadata
property of the User Task block to reference expiration details. For example, to send a time-sensitive notification. expiryMetadata
is an object with the following properties.
endDateEpochMs
The end date, in milliseconds since the UNIX epoch.
expiryTimeMs
The time, in milliseconds, until expiration.
type
The expiration type.
Within an app, you can reference a task's expiresAt
property to retrieve expiration details.
Specify task admins
Users in the permission groups you select can review and action tasks using the Retool app. You can optionally specify Task admin permission groups in the block's Settings which allow those users to manage the tasks in the Tasks Console.
Send new task notifications
The User Task block includes an additional connection to trigger another block when it creates a user task. Click and select a block to use. For example, you could add a Resource query block to send messages using Retool Email, Slack, etc.
When the User Task block creates a task, it generates a direct URL for the Retool app with a reference to a unique task ID in a URL parameter. You can reference the taskURL
property when sending notifications so that users can navigate directly to app and view the newly created task.
Review and action user tasks from an app
The starter app you create from the User Task block includes basic functionality for reviewing and actioning user tasks. You can modify the starter app based on your needs.
Write queries to interact with user tasks
Queries interact with user tasks within Retool apps. The user tasks app created by the workflow is preloaded with queries to get user tasks created by the workflow, get details of a specific task, and mark the user task as submitted
.
The starter app includes getUserTasks
, getSingleUserTask
, and submitUserTask
queries for you to use. To create these queries yourself:
- Open the Code tab.
- Create a Resource query.
- Select the User Action resource.
- Select the User Task type.
There are three actions from which you can choose when querying user tasks.
- Get All User Tasks
- Get User Task
- Complete User Task
- Reassign User Task
- Cancel User Task
The Get All User Tasks action retrieves a list of all user tasks for which the current user has access. You can specify the following options:
Option | Description |
---|---|
Workflow | The workflow that created the user task. |
User task | The name of the User Task block within the workflow. A workflow can create user tasks using multiple User Task blocks. |
Status | The task status. |
Created After | User tasks created after the specified date. |
Created Before | User tasks created before the specified date |
Submitted After | User tasks actioned as submitted after the specified date. |
Submitted Before | User tasks actioned as submitted before the specified date. |
Next Token | The next token from the previous API response. This is used for pagination for an arbitrary number of tasks. |
Use the Get User Task action to retrieve a specific user task using the provided task ID. When you run a workflow containing User Task blocks, the taskURL
of the associated block includes the the user Task ID as a URL parameter (urlparams.hash.userTaskId
) to direct a user to that specific task.
You can specify the following options:
Option | Description |
---|---|
User Task ID | The ID of the user task to retrieve. |
Use the Submit User Task action to mark the user task as submitted
. The workflow resumes its run and receives any specified output from the app.
You can specify the following options:
Option | Description |
---|---|
User Task ID | The ID of the user task to action. |
Task Output | A value that is passed to the workflow. |
Use the Reassign User Task action to reassign the task to a different permission group.
You can specify the following options:
Option | Description |
---|---|
User Task ID | The ID of the user task to action. |
Reassign To | A list of permission groups for which you can assign. |
Use the Cancel User Task action to cancel the task. Canceled tasks have a status of canceled
.
You can specify the following options:
Option | Description |
---|---|
User Task ID | The ID of the user task to action. |
Cancellation Reason | The reason for canceling the user task. |
Task context and output
Each user task has state. A user task's context
property contains the information provided by the workflow, such as the task context, which you can reference anywhere in the app.
The Complete User Task action includes an optional output that is saved to output
. This data is passed back to the workflow to use as it resumes.
You can build workflows with conditional logic that perform different actions based on this output. For example, you can use the Branch block to determine whether to reimburse an expense based on whether the output contains "approved": true
or "approved": false
.
Manage tasks with the Tasks Console
The Tasks Console cannot be used to action user tasks. Use a Retool app to review and action user tasks.
The Tasks tab of the organization contains the Tasks Console. From here, users can search for tasks, view task details, change the assigned permission group, or cancel tasks.
Admins can view all tasks across the organization. Task admins—users in permission groups specified in the User Task block settings—can only view tasks for which they are designated as task admins. All other users cannot access the Tasks Console.
View task information
The Tasks Console displays a table of all user tasks. Each column corresponds to a property of the User Task object. To view more details about a specific task, click > to expand the row.
Cancel a task
User tasks are initially created with a pending
status. Tasks that are no longer required can be canceled by clicking Cancel Task.
Reassign a task
Click Reassign Task to change the permission groups for a specific user task. As with User Task block permissions, you can select users and permission groups from a list or dynamically assign them.
User task storage for self-hosted deployments
Retool stores all data related to user tasks, including user task context and outputs, in your deployment's externalized postgres
database.
