Create and Delete Worker Task Templates

You can use a worker template to customize the interface and instructions that your workers see when working on your tasks. Use the instructions on this page to create a worker task template in the Augmented AI area of the Amazon SageMaker AI console. A starter template is provided for Amazon Textract and Amazon Rekognition tasks. To learn how to customize your template using HTML crowd elements, see Create Custom Worker Task Templates.

When you create a worker template in the worker task templates page of the Augmented AI area of the SageMaker AI console, a worker task template ARN is generated. Use this ARN as the input to HumanTaskUiArn when you create a flow definition using the API operation CreateFlowDefinition. You can choose this template when creating a human review workflow on the human review workflows page of the console.

If you are creating a worker task template resource for an Amazon Textract or Amazon Rekognition task type, you can preview the worker UI that is generated from your template on the worker task templates console page. You must attach the policy described in Enable Worker Task Template Previews to the IAM role that you use to preview the template.

Create a Worker Task Template

You can create a worker task template using the SageMaker AI console and using the SageMaker API operation CreateHumanTaskUi.

Create a worker task template (console)

  1. Open the Amazon A2I console at https://console.aws.amazon.com/a2i/.

  2. Under Amazon Augmented AI in the left navigation pane, choose Worker task templates.

  3. Choose Create template.

  4. In Template name, enter a unique name.

  5. (Optional) Enter an IAM role that grants Amazon A2I the permissions necessary to call services on your behalf.

  6. In Template type, choose a template type from the dropdown list. If you are creating a template for a Textract-form extraction or Rekognition-image moderation task, choose the appropriate option.

  7. Enter your custom template elements as follows:

    • If you selected the Amazon Textract or Amazon Rekognition task template, the Template editor autopopulates with a default template that you can customize.

    • If you are using a custom template, enter your predefined template in the editor.

  8. (Optional) To complete this step, you must provide an IAM role ARN with permission to read Amazon S3 objects that get rendered on your user interface in Step 5.

    You can only preview your template if you are creating templates for Amazon Textract or Amazon Rekognition.

    Choose See preview to preview the interface and instructions that workers see. This is an interactive preview. After you complete the sample task and choose Submit, you see the resulting output from the task that you just performed.

    If you are creating a worker task template for a custom task type, you can preview your worker task UI using RenderUiTemplate. For more information, see Preview a Worker Task Template.

  9. When you're satisfied with your template, choose Create.

After you've created your template, you can select that template when you create a human review workflow in the console. Your template also appears in the Amazon Augmented AI section of the SageMaker AI console under Worker task templates. Choose your template to view its ARN. Use this ARN when using the CreateFlowDefinition API operation .

Create a worker task template using a worker task template (API)

To generate a worker task template using the SageMaker API operation CreateHumanTaskUi, specify a name for your UI in HumanTaskUiName and input your HTML template in Content under UiTemplate.

Delete a Worker Task Template

Once you have created a worker task template, you can delete it using the SageMaker AI console or the SageMaker API operation DeleteHumanTaskUi.

When you delete a worker task template, you are not able to use human review workflows (flow definitions) created using that template to start human loops. Any human loops that have already been created using the worker task template that you delete continue to be processed until completion and are not impacted.
