Klaviyo allows you to disable and re-enable API keys without permanently deleting them. This is useful if you want to temporarily pause a key’s activity - for example, while investigating suspicious behavior - while preserving the option to restore it later.

This article covers:

  • How to disable an API key
  • How to re-enable an API key
  • What to do if Klaviyo has disabled a key on your behalf

Before you begin

You must have API Key Write permission on your account to disable or re-enable API keys. If you do not see the options described below, contact your account owner or admin to adjust your permissions.

How to disable an API key

  1. Log into your Klaviyo account.
  2. Navigate to Settings > API Keys.
  3. Locate the key you want to disable. You can use the key name or the partial key value to identify it.
  4. Click the (more options) menu next to the key.
  5. Select Disable.
  6. Confirm the action in the dialog that appears.

The key will immediately stop accepting API calls. It will appear as Disabled in your key list and will be grayed out. No data is deleted, and the key can be re-enabled at any time.

Note: Disabling a key will pause any integrations or workflows that rely on it. Before disabling, make sure you know which systems are using the key, or check the key’s activity under Settings > API Keys > [Key Name] > Activity.

How to re-enable an API key

  1. Log into your Klaviyo account.
  2. Navigate to Settings > API Keys.
  3. Locate the disabled key. Disabled keys are grayed out and labeled Disabled.
  4. Click the (more options) menu next to the key.
  5. Select Re-enable.
  6. Confirm the action in the dialog that appears.

The key will immediately resume accepting API calls.
