Connect AI agents to your Klaviyo account
AI agents that read your Klaviyo lists, segments, and campaigns, draft new records, and post the result to Slack: campaign briefs, lifecycle audits, and marketing hygiene.
How a Fidelic agent reaches Klaviyo.
What's wired
Fidelic agents connect to Klaviyo through OAuth + the Klaviyo API. Your agent reads the lists, segments, and campaigns the account admin explicitly grants.
When the agent reads, it stays inside the lists you've shared. Nothing leaves your Klaviyo account unless the agent posts a brief to Slack or creates a draft segment or campaign you authorized.
How to connect
Before you start
- A Klaviyo account on any plan.
- Admin role with API-key permission.
- A Slack workspace where the agent will live and post.
- A decision on which Klaviyo lists the agent should reach.
- About five minutes for the OAuth flow.
Connection steps
- Sign in to FidelicAI and pick the agent. From the Roster, pick the marketing agent.
- Authorize Klaviyo. Click Connect Klaviyo. The OAuth dialog opens; sign in with your admin account. The app appears in Settings → Integrations.
- Pick the lists the agent should reach. Pick the lists, segments, and campaigns the agent will read or write to.
- Confirm and finish. The agent runs a test read. When it passes, your Slack channel shows a Connected to Klaviyo message.
- Try the first agent action. Ask for a campaign brief in Slack.
Connection limits
Where the connection draws the line:
- · The agent only reads lists and segments the admin explicitly shares.
- · Klaviyo flows run server-side; the agent reads their output, not the flow definitions.
- · Sending campaigns versus drafting requires an explicit write scope.
Where the data goes
The connection runs inside your sandboxed Anthropic project. One project key per FidelicAI customer; FidelicAI infrastructure does not see your platform data.
Anything the agent reads stays inside your environment. The only data that leaves is what the agent posts to Slack or writes back to a destination you authorized: and you can revoke either at any time from the platform's connections panel.

Follow the connected questions
Start and work together includes this decision and the questions that usually change it.
Which systems should an AI agent connect to?
Connect the smallest set of systems needed to read the source, write the work product, and preserve the record the business already uses.
Inspect supported integrations →What data should an AI agent be allowed to access?
Grant only the systems and records required for the role. Keep credentials, customer boundaries, logs, and approval rules explicit.
Where should an AI agent’s work appear?
Use the environment where the right people can see the result, inspect the source trail, correct it, and make the next decision.
