LLM Connector in action

You can use the Mock Response feature to validate your flows for external calls without consuming AI tokens.

Configuration with User Prompt Only

This configuration uses only the User Prompt parameter to send a request to the AI model.

Practical example

  • Use case: A pipeline integrated with Zendesk receives a new customer ticket. The LLM Connector is used to analyze the request and classify its topic.

  • Goal: Classify the topic of a support ticket.

User Prompt:

Classify the topic of the following customer request:  
"My payment was declined, but the amount was debited from my account. I need help fixing this."

Example output:

{
  "status": 200,
  "body": "Payment Issues"
}

Configuration with User + System Prompts

This configuration uses both the User Prompt and System Prompt parameters to guide the AI response.

Practical example

  • Use case: After classifying the support ticket, the pipeline queries a knowledge database. The LLM Connector is then used again to generate a personalized response for the customer.

  • Goal: Generate a custom response using predefined tone and style.

System Prompt:

You are a friendly and helpful support agent. Always use an empathetic tone and provide clear instructions. Return the message as plain text with no line breaks.

User Prompt:

Write a response to the customer below, explaining that we will investigate the payment and get back to them within 24 hours:  
"My payment was declined, but the amount was debited from my account. I need help fixing this."

Example output:

{
  "status": 200,
  "body": "Thank you for reaching out, and I’m sorry to hear about the payment issue. I completely understand how frustrating this must be. We’ll investigate this right away and get back to you with an update within 24 hours. In the meantime, please rest assured that we’re on it and will do everything we can to resolve this for you. If you have any additional details or questions, feel free to share them. We appreciate your patience!"
}

Configuration with Prompts + JSON Schema

This configuration uses User Prompt, System Prompt, and JSON Schema to generate a structured response.

Practical example

  • Use case: A pipeline receives a user-generated comment from an ISV (independent software vendor) platform. The LLM Connector sends the comment to the AI to evaluate whether it’s harmful or offensive. The returned score is then used to decide whether the comment should be published or if the user should be flagged.

  • Goal: Evaluate and score a comment’s harmfulness and determine whether it should be approved.

System Prompt:

You are a content moderator. Evaluate whether the comment is harmful, assign a score from 0 to 1 for severity, and indicate whether it should be approved.

User Prompt:

Evaluate the following comment:  
"I had a great experience with this company. The team is professional and very helpful."

JSON Schema:

{
  "$schema": "https://json-schema.org/draft/2020-12/schema",
  "title": "ModerationResult",
  "type": "object",
  "properties": {
    "status": {
      "type": "integer",
      "enum": [200],
      "description": "HTTP status code"
    },
    "body": {
      "type": "object",
      "properties": {
        "score": {
          "type": "string",
          "pattern": "^(0(\\.\\d+)?|1(\\.0+)?)$",
          "description": "Severity score from 0 to 1"
        },
        "label": {
          "type": "string",
          "description": "Label describing the content, e.g., harmless, potentially harmful"
        },
        "should_approve": {
          "type": "boolean",
          "description": "Indicates whether the comment should be approved"
        }
      },
      "required": ["score", "label", "should_approve"],
      "additionalProperties": false
    }
  },
  "required": ["status", "body"],
  "additionalProperties": false
}

Possible output:

{
  "body": {
    "status": "200",
    "body": {
      "score": "0",
      "label": "harmless",
      "should_approve": true
    }
  },
  "tokenUsage": {
    "inputTokenCount": 168,
    "outputTokenCount": 22,
    "totalTokenCount": 190
  }
}

Configuration with Prompts + plain JSON

This configuration uses User Prompt, System Prompt, and plain JSON (no schema) to return a structured response.

Practical example

  • Using the same use case as above, the prompts guide the AI to return a JSON object directly, without schema validation.

System Prompt:

You are a content moderator. 
Evaluate whether the comment is harmful, assign a score from 0 to 1 for severity, and indicate whether it should be approved.

User Prompt:

Evaluate the following comment:  
"I had a great experience with this company. The team is professional and very helpful."

Plain JSON:

{
  "score": "",
  "label": "",
  "should_approve": ""
}

Output:

{
  "body": {
    "score": "0",
    "label": "Not harmful",
    "should_approve": "yes"
  },
  "tokenUsage": {
    "inputTokenCount": 91,
    "outputTokenCount": 26,
    "totalTokenCount": 117
  }
}

Dynamic configuration: Prompt with Double Braces reference

This configuration uses the User Prompt field to dynamically inject data from a previous connector using Double Braces expressions. In addition, the System Prompt and Output Format fields are used to guide the AI and generate a structured response.

Practical example

  • Use case: A pipeline receives address data from a REST connector that queries a Brazilian public ZIP code API (OpenCEP). The LLM Connector is then used to classify the type of address as residential, commercial or rural, based on the street name and neighborhood returned by the API.

  • Goal: Categorize the address type using dynamic data from the previous connector.

System Prompt:

You are an address classification assistant. Based on the street name and neighborhood, classify the address as residential, commercial, or rural. Explain your reasoning.

User Prompt with Double Braces:

Use the following address to make your evaluation: {{message.body}}

Output Format Body:

{
  "type": "",
  "reason": ""
}

Possible output:

{
  "status": 200,
  "body": {
    "type": "residential",
    "reason": "The street name 'Rua Abilio Carvalho Bastos' and the neighborhood 'Fósforo' suggest a typical residential area. The presence of house numbers (até 799/800) further supports this classification, as commercial areas are more likely to have business names or larger ranges of numbers."
  }
}

FAQ

How can I test and experiment with my prompts?

Use the Execution Panel to test your prompts. The Run Selected Steps option is especially useful for testing prompts separately from the rest of the pipeline.

Can I use data from the previous connectors?

Yes. You can use Double Braces expressions to reference data from previous connectors and include it in your prompt.

How is sensitive data handled?

The connector doesn’t redact or filter payload data. We recommend following the same data handling practices used with other connectors.

Can I chain multiple LLM calls in one pipeline?

Yes. You can use the output of one LLM call as input for another. For example, first classify a support ticket, then generate a response based on the classification.

What if the LLM produces inaccurate or made-up results?

For critical tasks, reduce hallucination risk by splitting the process into smaller steps, such as generating first and verifying afterward. This gives you more control and lets you validate the result before using it.

What happens if the provider takes too long to respond?

If the provider takes too long to respond, the request will time out and an error message will be shown in the Execution Panel.
