Automated Text Translation and Generation using Replicate API - n8n Workflow

Users needing automated multilingual text translation or complex text generation.
Developers looking for robust Replicate API integration examples within an n8n workflow.
Data scientists automating large-scale text processing tasks.
Anyone seeking an efficient n8n template for managing asynchronous AI model operations.

• n8n users wanting a production-ready template featuring smart polling logic.

Leveraging external AI models often requires handling asynchronous requests—where the API returns an ID immediately, and the result must be fetched later. This comprehensive n8n workflow template solves this challenge by integrating the lucataco/seed-x-ppo model via Replicate.

This n8n workflow manages the entire lifecycle: authentication, parameter configuration, request submission, and a reliable polling loop to check the task status until completion or failure. This ensures that your text generation or translation tasks run smoothly, automatically retrying checks and providing a structured final response, making it an essential n8n template for serious AI automation.

This automation begins with the Manual n8n Trigger.

1. Setup and Parameters: The workflow first uses the Set API Token n8n node to securely configure the Replicate API key. Next, the Set Text Parameters n8n node defines the necessary inputs for the AI model, such as the text to translate, targetlanguage, and generation control parameters like maxlength and num_beams.


2. Initial Request: The Create Text Prediction n8n node (an HTTP Request) sends the generation job to Replicate. Because this is an asynchronous task, it returns a prediction ID.


3. Polling Loop Initiation: The Log Request code n8n node logs the prediction ID for monitoring, followed by a Wait 5s n8n node.


4. Status Checking: The Check Status n8n node pings the Replicate API using the prediction ID to fetch the current status.


5. Flow Control: The Is Complete? n8n node checks if the status is 'succeeded'.

1. Final Output: Both success and error paths converge at the Display Result n8n node, which formats the final output delivered by the n8n workflow.

1. Download: Copy the provided n8n workflow JSON data.


2. Import to n8n: Open your n8n instance, click 'Workflows', and choose 'New' -> 'Import from JSON'. Paste the n8n workflow JSON.


3. API Key Configuration: Locate the Set API Token n8n node. Replace the placeholder YOURREPLICATEAPITOKEN with your actual Replicate API key.


4. Parameter Customization: Navigate to the Set Text Parameters n8n node. Here, you must provide the input text and the targetlanguage for your translation or generation task.


5. Execution: Save the n8n workflow. Click the Manual Trigger n8n node and select 'Execute Workflow' to test the full automated flow.

Manual Trigger (n8n trigger): The starting point for this n8n workflow. Used for manual initiation and testing.
Set API Token (n8n node): Essential setup node. Stores the Replicate API key securely, allowing subsequent HTTP requests to authenticate.
Set Text Parameters (n8n node): Configures all required and optional inputs for the seed-x-ppo model, including the text to process and language specifications.
Create Text Prediction (HTTP Request n8n node): Sends the asynchronous request to the Replicate API, initiating the text generation process and capturing the prediction ID. Configured with a Bearer token authorization.
Log Request (Code n8n node): A utility node for logging request details, vital for debugging and monitoring the n8n workflow's execution.
Wait 5s / Wait 10s (Wait n8n node): Controls the delay between status checks, preventing API rate limiting and managing the polling interval efficiently.
Check Status (HTTP Request n8n node): Executes a GET request using the prediction ID to poll the status of the ongoing AI task.
Is Complete? / Has Failed? (IF n8n node): Core flow control nodes that intelligently route the execution based on the API response status (succeeded or failed), ensuring robust logic within the n8n workflow structure.

• Success Response / Error Response (Set n8n node): Formats the final, clean JSON output for the n8n execution, clearly indicating success or documenting any errors encountered during the generation process.
