How to get started with Google Vertex AI on Zapier

Google Vertex AI on Zapier lets you add powerful generative AI to your automated workflows without writing code. This guide walks you through connecting your Google Cloud account, creating a generative model in Vertex AI, and using it inside your Zaps to generate text, chat responses, and embeddings.

What you need before you start with Zapier

Before you can use Google Vertex AI in Zapier, make sure you have the following prerequisites in place:

• A Google Cloud project with Vertex AI enabled
• Billing enabled in your Google Cloud project
• At least one supported generative AI model deployed in Vertex AI
• A Zapier account with access to create and edit Zaps

How Google Vertex AI works in Zapier

The Google Vertex AI app in Zapier exposes several actions you can add as steps in your Zaps. Each action sends data from your trigger or previous steps into Vertex AI, receives the model output, and passes it to the rest of your workflow.

Typical use cases include:

• Summarizing incoming emails or support tickets
• Drafting responses to customer messages
• Classifying or tagging leads based on free-text input
• Generating product descriptions or marketing copy
• Creating vector embeddings to feed into downstream tools

Connect your Google Vertex AI account to Zapier

You only need to connect Google Vertex AI to Zapier once. After that, you can reuse the connection in multiple Zaps.

Step 1: Start a new Zap with a trigger

1. Log in to your Zapier account.
2. Click Create and choose New Zap.
3. Select and configure a trigger app, such as Gmail, Google Sheets, or a form tool.
4. Test the trigger to pull in sample data. This data will help you configure the Vertex AI step.

Step 2: Add Google Vertex AI as an action in Zapier

1. Click the + icon under your trigger step.
2. Search for Google Vertex AI in the action search bar.
3. Select the Google Vertex AI app.
4. Choose the action event you want to use, such as generating text or embeddings.

Step 3: Authorize Google Vertex AI in Zapier

The first time you use Google Vertex AI in Zapier, you will be asked to connect your Google Cloud account.

1. In the Account field, click Connect a new account.
2. Sign in with the Google account that has access to the correct Google Cloud project.
3. Grant Zapier permission to access Vertex AI and related Google Cloud resources.
4. Once connected, choose the new account from the dropdown.

If you manage multiple Google Cloud projects, ensure the one you select has Vertex AI enabled and contains the models you want to use.

Configure Google Vertex AI actions in Zapier

After connecting your account, you can configure how the Vertex AI action behaves inside Zapier. While the exact fields depend on the action you choose, most follow a similar pattern.

Choose your project and location in Zapier

1. Select the Project that hosts your Vertex AI models.
2. Pick the Location (region) that matches your deployed model.

Using the same project and region as your Vertex AI deployment helps avoid errors and latency.

Select your model in Zapier

Next, choose which Vertex AI model to use. Options may include:

• Text generation models for drafting or summarizing
• Chat models for conversational interactions
• Embedding models for vector representations of text

Different models have different capabilities and pricing, so select the one that best fits your Zap’s goal.

Define your prompt and inputs in Zapier

The core of your Vertex AI step in Zapier is the prompt and any input fields.

1. In the prompt or input field, write clear instructions for the model. For example: “Summarize this email in three bullet points.”
2. Use the Insert data menu to map data from earlier Zap steps (such as email bodies or form responses) into the prompt.
3. Configure optional parameters, such as maximum output length, temperature, or top-k settings, if they are available for your action.

Well-structured prompts make the integration between Google Vertex AI and Zapier more reliable and predictable.

Test your Vertex AI step in Zapier

1. Click Test on the Vertex AI action step.
2. Zapier sends sample data to Vertex AI and displays the model’s response.
3. Review the output and adjust your prompt or parameters if needed.
4. Repeat testing until you get consistent, useful results.

Use Google Vertex AI outputs in the rest of your Zapier workflow

Once the Vertex AI step works as expected, you can feed its output into additional steps within Zapier.

Common follow-up actions include:

• Sending AI-generated text via email or chat tools
• Storing summaries or classifications in spreadsheets or databases
• Passing embeddings into downstream services for search or recommendation
• Triggering conditional paths based on model-generated tags

Because every Zapier step can read data from previous ones, you can chain complex automations around a single model call from Vertex AI.

Troubleshooting Google Vertex AI in Zapier

If your Zap fails or returns unexpected output from Vertex AI, check the following areas:

• Project and region: Confirm they match your model deployment.
• Model availability: Ensure the selected model is deployed and accessible.
• Prompt clarity: Rewrite unclear instructions or overly long prompts.
• Input formatting: Check mapped fields for missing or malformed data.
• Permissions: Verify that the connected Google account still has the required Google Cloud roles.

You can always compare your configuration against the official Google Vertex AI on Zapier documentation to ensure settings are aligned.

Best practices for using Vertex AI with Zapier

To get the most from your integration, keep these best practices in mind:

• Start with small, simple prompts, then iterate based on test results.
• Limit model output length to what your downstream apps can handle.
• Use clear, structured instructions, like numbered lists or bullet-point formats.
• Mask or avoid sending highly sensitive personal data whenever possible.
• Monitor usage and costs in Google Cloud to stay within budget.

As you refine your Zaps, you can gradually introduce more complex use cases, such as multi-step reasoning or chaining several AI-powered actions.

Next steps with Zapier and Google Vertex AI

Once your first integration is working, you can clone or expand your Zapier workflows to cover more of your business processes. For strategic automation planning, you may find it useful to review additional automation best practices from specialist resources like Consultevo alongside the official Zapier support content.

By combining Google Vertex AI with flexible automation in Zapier, you can upgrade everyday workflows with generative AI, reduce manual work, and deliver faster, higher-quality responses across your tools.
