Description
Overview
This screenshot automation workflow captures both full-page and viewport screenshots of a specified website. As a no-code integration pipeline, it streamlines website visual capture, storage, and notification for users requiring automated image archiving and delivery. The process initiates via a manual trigger node, ensuring controlled execution.
Key Benefits
- Automates capturing of full-page and viewport screenshots with consistent parameters.
- Uploads screenshots directly to Dropbox for centralized storage and retrieval.
- Delivers screenshot images via HTML email, embedding visual content inline.
- Manual triggering allows precise control over execution timing in the orchestration pipeline.
Product Overview
This automation workflow begins with a manual trigger node that activates the sequence on demand. It creates an item containing a fixed website URL and recipient email address, which are then used to generate two distinct screenshots: a full-page capture and a viewport-only capture of the website. The screenshot generation uses an image capture API configured to 640 pixels width, with one node set for full-page mode and the other for viewport-only mode.
Following screenshot creation, the workflow downloads the image files via HTTP requests, retrieving binary data without persistence on intermediate nodes. These files are uploaded to Dropbox under predefined file paths, facilitating central storage and access control. The workflow merges upload completions before proceeding to send an email through AWS SES, embedding the screenshots inline in an HTML-formatted message.
Error handling relies on platform defaults, with no explicit retry or backoff logic configured. Credentials for Dropbox and AWS SES are required for file upload and email delivery, respectively. The workflow provides a deterministic sequence for capturing, storing, and sharing website screenshots in a controlled, manual execution environment.
Features and Outcomes
Core Automation
This automation workflow accepts manual trigger input and proceeds to generate screenshots based on static URL and email parameters. Utilizing a no-code integration pipeline, it branches to capture both full-page and viewport screenshots deterministically.
- Single-pass, synchronous evaluation from trigger to email delivery.
- Parallel screenshot generation nodes ensure simultaneous image capture.
- Sequential file retrieval and upload maintain data integrity.
Integrations and Intake
The workflow integrates with Uproc’s screenshot service via API credentials for image generation. AWS SES handles email dispatch using configured SMTP credentials. Dropbox is used for file storage, authenticated through OAuth credentials.
- Uproc API for screenshot generation with URL and mode parameters.
- Dropbox API for uploading binary image files to designated paths.
- AWS SES for sending HTML emails with embedded image URLs.
Outputs and Consumption
Outputs include binary image files stored in Dropbox and an HTML email containing inline images sent to the configured recipient. The workflow returns no synchronous response but completes after email dispatch.
- Stored PNG image files in Dropbox at /screenshots/sample.png and /screenshots/sample_fullpage.png.
- HTML email embedding screenshot images scaled to 320 pixels width.
- Manual trigger results in discrete execution cycles per run.
Workflow — End-to-End Execution
Step 1: Trigger
The workflow starts on manual execution through the n8n manual trigger node, requiring explicit user action to initiate the screenshot capture and delivery process.
Step 2: Processing
The function item node creates an object containing the target website URL and recipient email address. This data is passed unchanged to subsequent nodes without additional schema validation or transformation.
Step 3: Analysis
The workflow utilizes two Uproc nodes to generate screenshots: one configured for full-page capture, the other for the visible viewport only. Both nodes use identical width parameters to ensure image consistency. No conditional branching or threshold-based logic is applied.
Step 4: Delivery
After downloading screenshot files via HTTP requests, the workflow uploads them to Dropbox in parallel paths. Upon completion, it merges upload results and sends an HTML email via AWS SES. The email includes embedded images referencing the generated screenshots and is sent synchronously within the workflow execution.
Use Cases
Scenario 1
A web content manager needs to archive visual snapshots of a website regularly. This automation workflow enables manual capture and centralized storage of both full-page and viewport screenshots, providing structured image files accessible in Dropbox and delivered via email for review.
Scenario 2
Quality assurance teams require visual verification of website rendering across updates. By manually triggering this automation, they receive consistent screenshots that document page state, enabling deterministic comparison without manual capture or emailing.
Scenario 3
Developers monitoring UI changes want visual evidence emailed on demand. This workflow provides a controlled no-code integration that captures screenshots and sends them embedded in HTML emails, eliminating multi-step manual processes and ensuring reproducible output formatting.
How to use
To implement this screenshot automation workflow, import it into n8n and configure credentials for Uproc API, Dropbox, and AWS SES. The target website URL and recipient email are preset in the function node but can be modified as needed. Execute the workflow manually to initiate screenshot generation, file upload, and email dispatch. Expect an HTML email containing two embedded screenshots and corresponding image files stored in Dropbox after each run.
