Trigger Actions Inside Credentialed Web Accounts

Act on behalf of users inside authenticated web sessions. From submitting forms to uploading documents, turn static websites into programmable surfaces with consent, security, and precision.

Write your own story

If a user can do it in a browser, we can automate it through a structured, API-based workflow.

Submit Forms

Applications, service requests, profile updates, and more.

Upload Documents

ID verification, payroll files, compliance reports.

Trigger Workflows

Switch services, schedule tasks, confirm selections.

Modify Account Settings

Change plan options, update user preferences.

Execute Multi-Step Actions

Complete guided flows like cancellations or transitions.

How it Works

1. Authenticate the User

We create a secure session using the user’s credentials, including multi-factor login if needed.

2. Define the Job

Specify the exact action. This could include filling fields, clicking buttons, uploading files, or completing a flow.

3. Execute and Confirm

Deck performs the job inside a live browser session and returns a success or failure status along with logs and optional outputs.

The Writing’s on the Wall
