How do I connect the Klaviyo API with Modiva?

Create a Modiva account, generate an MCP key, and connect Klaviyo from your dashboard. Modiva runs the full OAuth flow and stores the encrypted token for you — no client secrets in your code.

What can I do with the Klaviyo API through Modiva?

Read & write profiles and lists, and read segments, campaigns, metrics, events and flows in Klaviyo. You get 15 typed tools grouped by resource (accounts_, profiles_, lists_, campaigns_, metrics_, flows_), callable over REST or the MCP server.

Do I need to handle OAuth or token refresh myself?

No. Modiva handles the Klaviyo OAuth handshake, token storage (envelope-encrypted) and automatic refresh. You call a single unified endpoint.

Can an AI agent use the Klaviyo API?

Yes — that is the point. Modiva exposes Klaviyo as Model Context Protocol (MCP) tools, so agents like Claude, Cursor or your own app can read and act on Klaviyo through one endpoint.
