Who is this for?

This workflow template is ideal for marketers, designers, content creators, and developers who need to generate custom text-based images dynamically. Whether you want to create social media graphics, placeholder images, or text-based LinkedIn carousels, this workflow provides a simple, no-code solution using an API that requires no authentication.

What problem does this workflow solve?

Creating text-based images often requires design software or complex integrations with graphic tools. This workflow eliminates that hassle by allowing users to generate images with custom text, font styles, colors, and background colors using a simple HTTP request. It’s perfect for automating image generation without relying on external tools or manual effort.

What this workflow does

This workflow leverages an HTTP request to a free API that generates text-based images dynamically. Here's what it enables you to do:

  • Define custom image text
  • Set image dimensions (width x height)
  • Choose a background color and text color using hex codes
  • Select a font family and font size
  • Specify the image format (PNG, JPG, or WebP)

The generated image can be used immediately, making it ideal for automating content creation workflows.

Setup

  1. Open the workflow in n8n.
  2. Modify the Set node to define your preferred image properties:
- text: The message displayed on the image.
- size: Image dimensions (e.g., 500x300 pixels).
- backgroundColor: Hex color code for the background.
- textColor: Hex color code for the text.
- fontFamily: Select from available font options (e.g., Pacifico, Ubuntu).
- fontSize: Define the text size.
- type: Choose the image format (PNG, JPG, or WebP).
  1. Execute the workflow to generate an image.
  2. The HTTP request returns the generated image, ready for use.

How to customize this workflow

    1. Adjust the Set node values to match your desired design.
      
    1. Use dynamic data for text, allowing personalized images based on user input.
      
    1. Automate image delivery by adding email or social media posting nodes.
      
    1. Integrate this workflow into larger automation sequences, such as content marketing pipelines.
      

Generate Text and Images from DummyJSON API

This n8n workflow demonstrates how to fetch data from the free DummyJSON API using the HTTP Request node and then prepare it for further processing using the Set node. It's a foundational example for interacting with external APIs and transforming data within n8n.

What it does

This workflow performs the following steps:

  1. Manual Trigger: Starts the workflow when manually executed.
  2. HTTP Request: Makes a GET request to the DummyJSON API to retrieve data.
  3. Edit Fields (Set): Processes the data received from the API, likely to extract or rename fields, or to set new values based on the API response.

Prerequisites/Requirements

  • n8n instance (cloud or self-hosted)

Setup/Usage

  1. Import the workflow: Import the provided JSON into your n8n instance.
  2. Execute the workflow: Click the "Execute workflow" button on the "Manual Trigger" node to run the workflow.
  3. Review the output: Observe the data retrieved by the "HTTP Request" node and how it's transformed by the "Edit Fields (Set)" node.

This workflow is ready to use as-is for fetching and basic processing of data from the DummyJSON API. You can expand upon it to integrate with other services, store the data, or perform more complex transformations.

Automate Reddit brand monitoring & responses with GPT-4o-mini, Sheets & Slack

How it Works This workflow automates intelligent Reddit marketing by monitoring brand mentions, analyzing sentiment with AI, and engaging authentically with communities. Every 24 hours, the system searches Reddit for posts containing your configured brand keywords across all subreddits, finding up to 50 of the newest mentions to analyze. Each discovered post is sent to OpenAI's GPT-4o-mini model for comprehensive analysis. The AI evaluates sentiment (positive/neutral/negative), assigns an engagement score (0-100), determines relevance to your brand, and generates contextual, helpful responses that add genuine value to the conversation. It also classifies the response type (educational/supportive/promotional) and provides reasoning for whether engagement is appropriate. The workflow intelligently filters posts using a multi-criteria system: only posts that are relevant to your brand, score above 60 in engagement quality, and warrant a response type other than "pass" proceed to engagement. This prevents spam and ensures every interaction is meaningful. Selected posts are processed one at a time through a loop to respect Reddit's rate limits. For each worthy post, the AI-generated comment is posted, and complete interaction data is logged to Google Sheets including timestamp, post details, sentiment, engagement scores, and success status. This creates a permanent audit trail and analytics database. At the end of each run, the workflow aggregates all data into a comprehensive daily summary report with total posts analyzed, comments posted, engagement rate, sentiment breakdown, and the top 5 engagement opportunities ranked by score. This report is automatically sent to Slack with formatted metrics, giving your team instant visibility into your Reddit marketing performance. --- Who is this for?
