4. Attach Schema Output Parser to Topic Idea Generator as the output parser and keep the JSON schema example.
5. For Schema Output Parser (AI sub-node), add credentials to the parent node Primary Chat Model, not the parser itself.

Step 3: Set Up the Post Draft Composer

Turn the topic idea into a LinkedIn post draft and image description using a second model and parser.

3. Credential Required: Connect your openAiApi credentials in Secondary Chat Model.
4. Attach Post Output Parser to Post Draft Composer and keep the JSON schema example.
5. For Post Output Parser (AI sub-node), add credentials to the parent node Secondary Chat Model, not the parser itself.

Step 4: Configure Parallel Image and Hashtag Generation

After drafting the post, the workflow generates an image prompt and hashtags in parallel.

1. Ensure Post Draft Composer outputs to both Image Render Request and Hashtag Strategy Agent in parallel.
2. In Image Render Request, set Prompt to =Generate an image for a linkedin post this is the description: {{ $json.output['image description'] }} .The images should be realistic for linkedin. and set Resource to image.

5. Attach Tertiary Chat Model as the language model for Hashtag Strategy Agent.
6. Credential Required: Connect your openAiApi credentials in Tertiary Chat Model.
7. Attach Hashtag Output Parser to Hashtag Strategy Agent and keep the JSON schema example.
8. For Hashtag Output Parser (AI sub-node), add credentials to the parent node Tertiary Chat Model, not the parser itself.

Step 5: Configure LinkedIn Publishing

3. In LinkedIn Publisher, set Post As to organization and Share Media Category to IMAGE.
4. Credential Required: Connect your linkedInOAuth2Api credentials in LinkedIn Publisher.

Step 6: Test and Activate Your Workflow

Validate that the workflow generates a post, image, and hashtags, then publish it to LinkedIn.

1. Click Execute Workflow to run Scheduled Automation Start manually.
2. Verify outputs from Topic Idea Generator and Post Draft Composer include structured fields from the parsers.
3. Confirm Image Render Request returns an image result and Hashtag Strategy Agent returns a comma-separated hashtag list.
4. Check LinkedIn Publisher to ensure a post is created with image media.
5. Toggle the workflow to Active for scheduled production runs.
