Overview

The ModuleX Klaviyo integration lets a ModuleX agent operate Klaviyo on your behalf — running create actions across lists, profiles and members to lists — directly from a plain-English request, using your organization's own Klaviyo credentials. No pre-built workflow is required: the agent picks the right Klaviyo action for the task.

Klaviyo is a marketing & advertising platform. ModuleX adds the agent layer: ask for an outcome and it selects and runs the right Klaviyo action — or, when you want a repeatable process, the composer assembles a Klaviyo workflow for you, streaming the nodes onto the canvas as it builds.

Ask the assistant

Drive Klaviyo in plain English

Type what you want. A ModuleX agent picks the right Klaviyo action — or chains several — and runs it. No workflow to build.

Two ways

Two ways to use Klaviyo in ModuleX

Ask the assistantType what you want done and a ModuleX agent picks the right Klaviyo action and runs it — no workflow to build.

Compose a workflowNeed it to happen every time? Describe the process and the composer wires Klaviyo into a repeatable workflow you can run on a schedule, from chat, or as an API.

Security

Connecting Klaviyo

API keyKlaviyo uses API-key authentication. You provide your own Klaviyo secret key; ModuleX encrypts it and scopes it to your organization, so your whole team can use Klaviyo without re-authenticating.

Step-by-step setup in the Klaviyo docs

Pairs well with Klaviyo

Agents often chain Klaviyo with these — connect them once and the agent can use all of them in a single task.

FAQ

Klaviyo + ModuleX FAQ

A ModuleX agent can run any of Klaviyo's 5 actions — across lists, profiles and members to lists — from a plain-English request, using your organization's own Klaviyo credentials.

No. The agent selects the right Klaviyo action from your prompt. A workflow is only needed when you want a repeatable process — and the composer builds that for you from a description.

Via your own Klaviyo API key, stored encrypted and scoped to your organization.

5, spanning lists, profiles and members to lists.

Klaviyo runs on your own credentials, so any Klaviyo usage is billed by Klaviyo directly. ModuleX meters the agent run — and if you connect your own model keys, there's no ModuleX markup on model usage.

Connect Klaviyo once with your own credentials and let your agent run all 5 actions on demand.
