Create Images from Text Prompts (Flux, Kontext Pro, Replicate)

This n8n workflow demonstrates how to generate images from text prompts using a combination of external AI services like Flux, Kontext Pro, and Replicate. It provides a foundational structure for integrating multiple image generation APIs and handling their responses.

What it does

This workflow is currently a template that outlines the structure for an image generation process but does not contain active API calls or specific logic for Flux, Kontext Pro, and Replicate within its current JSON definition. It includes the following core n8n nodes:

  1. When clicking 'Execute workflow' (Manual Trigger): Initiates the workflow manually, allowing for testing and on-demand execution.
  2. Edit Fields (Set): A placeholder node, likely intended for setting up or modifying data (e.g., text prompts, image parameters) before sending it to image generation services.
  3. HTTP Request: A versatile node for making API calls. This node would be used to interact with the Flux, Kontext Pro, and Replicate APIs to send text prompts and receive image generation requests or results.
  4. If: A conditional node for branching logic. This would typically be used to check the status of an API response, determine which service to use, or handle different outcomes.
  5. Wait: A node to pause the workflow for a specified duration. This is often crucial when dealing with asynchronous API calls, such as image generation services that might take time to process requests.
  6. Code: A node for executing custom JavaScript code. This can be used for complex data manipulation, parsing API responses, or implementing custom retry logic.
  7. Sticky Note: A documentation node for adding comments and explanations within the workflow.

Prerequisites/Requirements

While the specific API keys and service configurations are not present in this JSON, a complete implementation of this workflow would require:

  • Replicate Account & API Key: For utilizing Replicate's AI models.
  • Flux AI Account & API Key: For interacting with Flux AI services.
  • Kontext Pro Account & API Key: For leveraging Kontext Pro's capabilities.
  • n8n instance: A running n8n instance to host and execute the workflow.

Setup/Usage

  1. Import the workflow: Download the provided JSON and import it into your n8n instance.
  2. Configure API Keys: For a functional workflow, you would need to add and configure your API credentials for Replicate, Flux, and Kontext Pro within the respective HTTP Request nodes or as n8n credentials.
  3. Define Prompts and Logic:
    • Modify the "Edit Fields (Set)" node to define the text prompts or other parameters you want to send to the image generation services.
    • Populate the "HTTP Request" nodes with the correct API endpoints, headers (including API keys), and body for each service (Flux, Kontext Pro, Replicate).
    • Implement the conditional logic within the "If" node to handle different scenarios, such as checking for successful image generation or selecting between different services.
    • Adjust the "Wait" node's duration based on the expected processing time of the image generation APIs.
    • Use the "Code" node for any custom parsing of API responses or post-processing of the generated image data.
  4. Execute the workflow: Click the "Execute workflow" button in the "Manual Trigger" node to run the workflow.

Key settings: pricebook2Id (hardcoded in script): e.g., 01sxxxxxxxxxxxxxxx Source lines: $('Message a model').first().json.message.content.products Output: { soql, codes } --- 8) Query PricebookEntries (Salesforce) Purpose: Fetch PricebookEntry.Id for each Product2.ProductCode. Key settings: Resource: search Query: ={{ $json.soql }} Creds: salesforceOAuth2Api Output: Items with Id, Product2.ProductCode (used for mapping). --- 9) Code in JavaScript (Build OLI payloads) Purpose: Join lines with PBE results and Opportunity Id ➜ build OpportunityLineItem payloads. Inputs: OpportunityId: ={{ $('Create an opportunity').first().json.id }} Lines: ={{ $('Message a model').first().json.message.content.products }} PBE rows: from previous node items Output: { body: { allOrNone:false, records:[{ OpportunityLineItem... }] } } Notes: Converts discount_total ➜ per-unit if needed (currently commented for standard pricing). Throws on missing PBE mapping or empty lines. --- 10) Create Opportunity Line Items (HTTP Request) Purpose: Bulk create OLIs via Salesforce Composite API. Key settings: Method: POST URL: https://<your-instance>.my.salesforce.com/services/data/v65.0/composite/sobjects Auth: salesforceOAuth2Api (predefined credential) Body (JSON): ={{ $json.body }} Output: Composite API results (per-record statuses). --- 11) Update File to One Drive Purpose: Archive the original PDF in OneDrive.

If AI returns non-JSON, keep “Return only a JSON array” as the last line of the prompt and keep jsonOutput enabled. Consider adding validation on parsing.warnings to gate Salesforce writes. For discounts/taxes in OLI: Standard OLI fields don’t support per-line discount amounts directly; model them in UnitPrice or custom fields. Replace the Composite API URL with your org’s domain or use the Salesforce node’s Bulk Upsert for simplicity.
