🚀 AI-Powered LinkedIn Post Automation

---

🧩 How It Works

This workflow automatically generates LinkedIn posts based on a user-submitted topic, including both content creation and image generation, then publishes the post to LinkedIn. Ideal for marketers, content creators, or businesses looking to streamline their social media activity, without the need for manual post creation.

High-Level Workflow:

1. Trigger: The workflow is triggered when a user submits a form with a topic for the LinkedIn post.
2. Data Mapping: The topic is mapped and prepared for the AI model.
3. AI Content Generation: Calls the Google Gemini AI model to generate engaging post content and a visual image prompt.
4. Image Creation: Sends the image prompt to the external API, gen-imager, to generate a professional image matching the topic.
5. Post Creation: Publishes the text and image to LinkedIn, automatically updating the user's feed.

⚙️ Set Up Steps (Quick Overview)

🕐 Estimated Setup Time: ~10–20 minutes

1. Connect Google Gemini: Set up your Google Gemini API credentials to interact with the AI model for content creation.
2. Set Up External Image API: Configure the external image generation API (gen-imager API) for visual creation based on the post prompt.
3. Connect LinkedIn: Set up OAuth2 credentials to authenticate your LinkedIn account and allow publishing posts.
4. Form Submission Setup: Create a simple web form for users to submit the topic for LinkedIn posts.
5. Activate the Workflow: Once everything is connected, activate the workflow. It will trigger automatically upon receiving form submissions.

💡 Important Notes:

• The flow uses Google Gemini (PaLM) for generating content based on the user's topic.
• Text to Image: The image generation process involves creating a professional, LinkedIn-appropriate image based on the post’s topic using the gen-imager API.
• You can customize the visual elements of the posts and adjust the tone of the generated content based on preferences.
