How do I disconnect or revoke the Klaviyo integration?

Last updated May 20, 2026Integrations

Removing the Klaviyo integration from Valid Email Checker is a two-step process for full hygiene. Step one: delete the connection on our side. Step two: revoke the Private API Key inside Klaviyo. Step one cuts VEC off from Klaviyo; step two ensures the key cannot be reused even if it was copied elsewhere.

Step 1: delete the connection in VEC

Sign into VEC and open Integrations.
Find the Klaviyo row in Connected Integrations.
Click the three-dot row menu and pick Delete.
Confirm in the modal.
The Klaviyo entry vanishes from the table immediately.

Deleting the connection also clears the sync history attached to it. Past verification jobs remain in your Uploads & Results page as standalone records.

Step 2: revoke the Private API Key in Klaviyo

Sign into Klaviyo.
Click your account avatar in the top right.
Open Account → Settings → API Keys.
Find the Private API Key you used to connect to Valid Email Checker.
Click Delete next to that key. Klaviyo instantly invalidates the value.

Why revoke separately

Deleting on our side removes the stored credential. The key string itself is still a valid Klaviyo credential unless you delete it there. Klaviyo's Private API Keys page also surfaces per-key request logs, making it easy to verify VEC is no longer touching your account.

Public Key vs. Private Key reminder

Klaviyo exposes two key types: a Public API Key (used in client-side scripts, very limited scope) and Private API Keys (used in server-side integrations like VEC, with configurable scopes). Only the Private key needs revoking for the VEC integration. The Public key is unrelated and is safe to leave in place. Setup specifics live in the Klaviyo integration guide.

What happens to running verifications?

A verification mid-import keeps running with the cached credentials. New sync attempts fail immediately until you reconnect. To resume, walk through the connect flow in the Klaviyo integration guide.

Reconnecting later

Reconnect by going to Integrations → Connect Integration → Klaviyo and pasting a fresh Private API Key. The new connection is unrelated to the deleted one. If you previously named it something distinctive (helpful in multi-account workflows), reuse the name for team-facing consistency.

Team-member-created connections

Connections created by team members show a Users badge in the Provider column. Owners can delete any connection; team members can only delete connections they themselves created.
