OpenRouter Generate Response in Workflows

The Generate Response action allows you to use advanced AI models directly within workflows to create dynamic, context-aware responses from prompts you define. This enables automated content creation, intelligent replies, summarization, and AI-driven decision logic inside your automation flows.

The action sends your prompt to the selected AI model and returns a generated response that can be used in later workflow steps. This makes it possible to build automated messaging, personalized follow-ups, and structured AI-powered processes without manual input.

What Is the Generate Response Action?

The Generate Response action enables workflows to send prompts to an AI model and receive generated output in real time. The response can then be inserted into messages, stored in custom fields, or used to drive conditional workflow logic.

This action supports:

Custom prompts

System-level behavioral instructions

Workflow variables

Multiple AI model selections

How the Action Works

When a workflow reaches this action:

The selected AI model is invoked

The optional System Prompt defines tone or behavior

The main Prompt is sent to the model

The model generates a response

The response becomes available for use in later workflow actions

The output can be mapped or reused anywhere within the workflow.

Connecting Your OpenRouter Account

Before using the Generate Response action, your account must be connected.

Connect OpenRouter from the Integrations Page

Navigate toSettings → Integrations, locateOpenRouter, and clickConnectto authorize your account using your API key.

This makes the AI action available within your workflow sequence.

Action Configuration

The Generate Response action includes three primary configuration fields.

System Prompt (Optional)

The System Prompt defines the AI’s overall role, tone, or behavior. It influences how the model responds but does not contain the primary request.

Examples:

“You are a helpful customer support assistant.”

“Respond in a concise and professional tone.”

“You are an expert marketing copywriter.”

Use this field to guide style, formatting, or intent.

Prompt (Required)

The Prompt contains the main instruction or question sent to the AI model.

You may include:

Plain text

Workflow variables

Custom instructions

Examples:

“Write a follow-up email for {{contact.firstname}} about their missed appointment.”

“Summarize the following message in one sentence: {{inboundmessage.body}}”

“Generate a short sales pitch for this service: {{custom.servicedescription}}”

This field determines what the AI produces.

Model (Required)

Select the AI model that will generate the response.

Models may differ in:

Response quality

Speed

Cost

Creativity

Choose a model appropriate for your workflow objective.

Using the Generated Output

The AI-generated response can be used in several ways:

Inserted into SMS, Email, or messaging actions

Stored in a custom field

Used inside conditional logic

Passed to additional AI or workflow actions

This enables advanced automation sequences based on AI output.
