This workflow gets triggered every Friday at 6 PM with the help of a Cron node. It pulls in data about a random cocktail via the HTTP Request Node and sends the data to a Bannerbear node to create an image based on a template. The image is then finally shared on a specified Rocket.Chat channel.

n8n Workflow: Render Custom Text Over Images with Bannerbear

This n8n workflow demonstrates how to automate the creation of custom images by rendering text over a base image using Bannerbear. It's triggered on a schedule, makes an HTTP request (though not fully configured in the provided JSON), and then uses Bannerbear to generate an image before potentially posting a message to RocketChat.

What it does

This workflow simplifies the process of dynamically generating images with custom text overlays.

Scheduled Trigger: The workflow is initiated on a recurring schedule (configured via the Cron node).
HTTP Request (Placeholder): It includes an HTTP Request node, which is currently unconfigured. This node could be used to fetch data (e.g., text content, image URLs) from an external API or database.
Generate Image with Bannerbear: It utilizes the Bannerbear node to create an image. This node is designed to take a template and dynamic text/image inputs to render a new image.
Post to RocketChat (Placeholder): The workflow includes a RocketChat node, currently unconfigured. This node could be used to post the newly generated image or a link to it to a RocketChat channel.

Prerequisites/Requirements

n8n Instance: A running n8n instance.
Bannerbear Account: An active Bannerbear account with an API Key and at least one image template configured.
RocketChat Account (Optional): If you intend to use the RocketChat integration, you'll need a RocketChat account and appropriate credentials.

Setup/Usage

Import the Workflow:
- Copy the provided JSON code.
- In your n8n instance, go to "Workflows" and click "New".
- Click the three dots in the top right corner and select "Import from JSON".
- Paste the JSON code and click "Import".
Configure Credentials:
- Bannerbear: Click on the "Bannerbear" node. You will need to set up a Bannerbear API credential.
  - In the Bannerbear node settings, select "Create New Credential".
  - Enter your Bannerbear API Key.
- RocketChat (Optional): If you plan to use the RocketChat node, click on it and configure your RocketChat API credentials (e.g., API Key, User ID, Host).
Configure Nodes:
- Cron: Adjust the schedule in the "Cron" node to your desired frequency.
- HTTP Request: If you have an external data source, configure the "HTTP Request" node to fetch the necessary text or image data.
- Bannerbear:
  - Select the "Operation" (e.g., "Create Image").
  - Choose your Bannerbear "Template ID".
  - Map the data from previous nodes (or provide static values) to the "Modifications" section to customize the text and images on your Bannerbear template.
- RocketChat: If using, configure the "RocketChat" node to post the generated image URL or a message to your desired channel.
Activate the Workflow: Once configured, enable the workflow by toggling the "Active" switch in the top right corner of the workflow editor.

Synchronizing WooCommerce inventory and creating products with Google Gemini AI and BrowserAct

Synchronize WooCommerce Inventory & Create Products with Gemini AI & BrowserAct This sophisticated n8n template automates WooCommerce inventory management by scraping supplier data, updating existing products, and intelligently creating new ones with AI-formatted descriptions. This workflow is essential for e-commerce operators, dropshippers, and inventory managers who need to ensure their product pricing and stock levels are synchronized with multiple third-party suppliers, minimizing overselling and maximizing profit. --- Self-Hosted Only This Workflow uses a community contribution and is designed and tested for self-hosted n8n instances only. --- How it works The workflow is typically run by a Schedule Trigger (though a Manual Trigger is also shown) to check stock automatically. It reads a list of suppliers and their inventory page URLs from a central Google Sheet. The workflow loops through each supplier: A BrowserAct node scrapes the current stock and price data from the supplier's inventory page. A Code node parses this bulk data into individual product items. It then loops through each individual product found. The workflow checks WooCommerce to see if the product already exists based on its name. If the product exists: It proceeds to update the existing product's price and stock quantity. If the product DOES NOT exist: An If node checks if the missing product's category matches a predefined type (optional filtering). If it passes the filter, a second BrowserAct workflow scrapes detailed product attributes from a dedicated product page (e.g., DigiKey). An AI Agent (Gemini) transforms these attributes into a specific, styled HTML table for the product description. Finally, the product is created in WooCommerce with all scraped details and the AI-generated description. Error Handling: Multiple Slack nodes are configured to alert your team immediately if any scraping task fails or if the product update/creation process encounters an issue. Note: This workflow does not support image uploads for new products. To enable this functionality, you must modify both the n8n and BrowserAct workflows. --- Requirements BrowserAct API account for web scraping BrowserAct n8n Community Node -> (n8n Nodes BrowserAct) BrowserAct templates named “WooCommerce Inventory & Stock Synchronization” and “WooCommerce Product Data Reconciliation” Google Sheets credentials for the supplier list WooCommerce credentials for product management Google Gemini account for the AI Agent Slack credentials for error alerts --- Need Help?
