Paste it into Letaido

Copy the key and paste it into Letaido. Scopes can't be added to a key later; a new key fixes that.

Describe the job

Name the list, segment or flow so the agent does not have to guess.

Frequently asked

How do I connect Klaviyo to Letaido? +

Create a private API key in Klaviyo under Settings, Account, API keys, as an Owner or Admin, and paste it into Letaido.

What if my Klaviyo API key is missing a scope? +

Scopes can't be added to a Klaviyo key later. Create a new private key with the read and write scopes you want and paste it into Letaido.

Can a Klaviyo event start a job? +

Only on Advanced KDP accounts, because Klaviyo offers webhooks only there. Other accounts run Klaviyo jobs on a schedule, or start them from another app's event, like the failed Stripe payment job above.

Will it send campaigns to my Klaviyo audience? +

It can, if a job asks for it. Allow all read operations once per app; approve each kind of write once. None of the jobs above sends; the campaign job saves a draft.

What do I approve before it changes Klaviyo? +

Allow all read operations once per app; approve each kind of write once.

How does it handle Klaviyo's reporting limits? +

Klaviyo allows 2 report queries a minute and 225 a day per account. So results jobs, like the weekly Slack post, keep report calls to a minimum: one for campaigns and one for flows.

Is there a Klaviyo MCP server? +

Yes. Klaviyo's MCP server lets AI clients such as Claude or Cursor read your data and create campaigns. Letaido is not an MCP server. It has its own Klaviyo connector, mixes it with your other apps and runs jobs on a schedule or when you ask.

How is Letaido different from Klaviyo's built-in integrations? +

Each built-in integration syncs what its builder chose, between Klaviyo and that one tool. Letaido's agent works with Klaviyo and 64 other apps in one job, like a weekly results post. It connects 65 apps, not thousands.

Give your email marketing an agent

Connect Klaviyo, then ask for a job like "Post weekly Klaviyo campaign and flow results in Slack". Leta gets it done on your schedule, or the moment you ask.
