Klaviyo
The Klaviyo agent connector is a Python package that equips AI agents to interact with Klaviyo through strongly typed, well-documented tools. It's ready to use directly in your Python app, in an agent framework, or exposed through an MCP.
Klaviyo is a marketing automation platform that helps businesses build customer relationships through personalized email, SMS, and push notifications. This connector provides access to Klaviyo's core entities including profiles, lists, campaigns, events, metrics, flows, and email templates for marketing analytics and customer engagement insights.
Example prompts
The Klaviyo connector is optimized to handle prompts like these.
- List all profiles in my Klaviyo account
- Show me details for a recent profile
- Show me all email lists
- Show me details for a recent email list
- What campaigns have been created?
- Show me details for a recent campaign
- Show me all email campaigns
- List all events for tracking customer actions
- Show me all metrics (event types)
- Show me details for a recent metric
- What automated flows are configured?
- Show me details for a recent flow
- List all email templates
- Show me details for a recent email template
Unsupported prompts
The Klaviyo connector isn't currently able to handle prompts like these.
- Create a new profile
- Update a profile's email address
- Delete a list
- Send an email campaign
- Add a profile to a list
Entities and actions
This connector supports the following entities and actions. For more details, see this connector's full reference documentation.
| Entity | Actions |
|---|---|
| Profiles | List, Get, Context Store Search, Context Store SQL Query |
| Lists | List, Get, Context Store Search, Context Store SQL Query |
| Campaigns | List, Get, Context Store Search, Context Store SQL Query |
| Events | List, Context Store Search, Context Store SQL Query |
| Metrics | List, Get, Context Store Search, Context Store SQL Query |
| Flows | List, Get, Context Store Search, Context Store SQL Query |
| Email Templates | List, Get, Context Store Search, Context Store SQL Query, Semantic Search |
Klaviyo API docs
See the official Klaviyo API reference.
Interfaces
Use the Klaviyo connector through the Airbyte Agent CLI, the Python SDK, or the API.
CLI
Install the CLI:
curl -fsSL https://airbyte.ai/install.sh | bash
Authenticate with Airbyte:
airbyte-agent login
Create the connector. The CLI opens the hosted setup flow:
airbyte-agent connectors create --json '{
"workspace": "<your_workspace_name>",
"name": "klaviyo"
}'
Describe the connector to see its supported entities and actions:
airbyte-agent connectors describe --json '{
"workspace": "<your_workspace_name>",
"name": "klaviyo"
}'
Execute an action:
airbyte-agent connectors execute --json '{
"workspace": "<your_workspace_name>",
"name": "klaviyo",
"entity": "profiles",
"action": "list"
}'
Python SDK
Installation
uv pip install airbyte-agent-sdk
Usage
Connectors can run in hosted or open source mode.
Hosted
In hosted mode, API credentials are stored securely in Airbyte Agents. You provide your Airbyte credentials instead.
If your Airbyte client can access multiple organizations, also set organization_id.
This example assumes you've already authenticated your connector with Airbyte. See Authentication to learn more about authenticating. If you need a step-by-step guide, see the hosted execution tutorial.
The connect() factory returns a fully typed KlaviyoConnector and reads AIRBYTE_CLIENT_ID / AIRBYTE_CLIENT_SECRET from the environment:
The recommended pattern is build_connector_tools, which gives the agent three tools bound to this connector: inspect_connector, read_skill_docs, and execute. The agent can inspect the connector, read only the skill-doc section it needs, and then execute:
inspect_connector() -> read_skill_docs() -> read_skill_docs(section="...") -> execute(entity, action, params)
Pass section IDs verbatim as the outline lists them, prefix included (actions.<entity>.<action>, not <entity>.<action>); anything else returns an error the agent has to recover from.
The builder names its tools inspect_connector, read_skill_docs, and execute, so the tool sets for more than one connector collide when registered on the same agent. Renaming the callables at registration avoids the collision, but the generated execute guidance still names inspect_connector and read_skill_docs, pointing the model at the wrong tools. Use the agent_tool pattern below instead: it weaves your own names into that guidance.

Custom tool bodies
When you need custom tool bodies — or a framework without native support — use KlaviyoConnector.agent_tool. Register execute, inspect, and docs together so the agent can fetch connector guidance progressively. Pass the framework explicitly when it has a supported failure strategy:
from pydantic_ai import Agent
from airbyte_agent_sdk import connect
from airbyte_agent_sdk.connectors.klaviyo import KlaviyoConnector
connector = connect("klaviyo", workspace_name="<your_workspace_name>")
agent = Agent("openai:gpt-4o")
@agent.tool_plain
@KlaviyoConnector.agent_tool(
framework="pydantic_ai",
inspect_tool="klaviyo_inspect",
docs_tool="klaviyo_read_docs",
)
async def klaviyo_execute(entity: str, action: str, params: dict | None = None):
return await connector.execute(entity, action, params or {})
@agent.tool_plain
@KlaviyoConnector.agent_tool(framework="pydantic_ai")
async def klaviyo_inspect():
return await connector.inspect_connector()
@agent.tool_plain
@KlaviyoConnector.agent_tool(framework="pydantic_ai")
async def klaviyo_read_docs(section: str | None = None):
return await connector.read_skill_docs(section)
Use the same three-function pattern with framework="langchain", "openai_agents", or "mcp" and that framework's registration decorator. Each value translates connector failures into the framework's own signal:
framework= | Tool failures surface as |
|---|---|
"pydantic_ai" | pydantic_ai.ModelRetry |
"langchain" | langchain_core.tools.ToolException (set handle_tool_error=True to feed it back to the model) |
"openai_agents" | the failure message returned to the model as the tool result |
"mcp" | fastmcp.exceptions.ToolError |
"none" (default) | airbyte_agent_sdk.AirbyteToolError |
On a framework the SDK does not support natively — or in a raw LLM dispatch loop — omit framework= and handle AirbyteToolError yourself:
from airbyte_agent_sdk import AirbyteToolError
from airbyte_agent_sdk import connect
from airbyte_agent_sdk.connectors.klaviyo import KlaviyoConnector
connector = connect("klaviyo", workspace_name="<your_workspace_name>")
@KlaviyoConnector.agent_tool(
inspect_tool="klaviyo_inspect",
docs_tool="klaviyo_read_docs",
)
async def klaviyo_execute(entity: str, action: str, params: dict | None = None):
return await connector.execute(entity, action, params or {})
@KlaviyoConnector.agent_tool()
async def klaviyo_inspect():
return await connector.inspect_connector()
@KlaviyoConnector.agent_tool()
async def klaviyo_read_docs(section: str | None = None):
return await connector.read_skill_docs(section)
# Advertise all three to the model, using each function's docstring as its description.
handlers = {
fn.__name__: fn
for fn in (klaviyo_inspect, klaviyo_read_docs, klaviyo_execute)
}
# `tool_name` and `tool_args` come from the model's tool call in your dispatch loop.
try:
tool_result = await handlers[tool_name](**tool_args)
except AirbyteToolError as err:
tool_result = str(err) # hand the message back to the model as an errored tool result
Each function's docstring carries the guidance the model needs, so pass it through as the tool description wherever you register it.
Legacy alternatives
These examples are kept for existing integrations. The deprecated KlaviyoConnector.tool_utils pattern loads the connector's full generated catalog into one broad execute tool description instead of letting the agent read skill docs on demand. For new code, use build_connector_tools or KlaviyoConnector.agent_tool above.

Open source
In open source mode, you provide API credentials directly to the connector.
The recommended pattern is build_connector_tools, which gives the agent three tools bound to this connector: inspect_connector, read_skill_docs, and execute. The agent can inspect the connector, read only the skill-doc section it needs, and then execute:
inspect_connector() -> read_skill_docs() -> read_skill_docs(section="...") -> execute(entity, action, params)
Pass section IDs verbatim as the outline lists them, prefix included (actions.<entity>.<action>, not <entity>.<action>); anything else returns an error the agent has to recover from.
The builder names its tools inspect_connector, read_skill_docs, and execute, so the tool sets for more than one connector collide when registered on the same agent. Renaming the callables at registration avoids the collision, but the generated execute guidance still names inspect_connector and read_skill_docs, pointing the model at the wrong tools. Use the agent_tool pattern below instead: it weaves your own names into that guidance.
