Integrations

Ken + Anthropic Integration

Add your Anthropic API key in Ken to run campaign AI steps on Anthropic models at 0 Ken credits, because Anthropic bills your own account for the tokens.

What the Integration Does

In short Your own Anthropic key runs campaign AI steps on Anthropic models at 0 Ken credits.

Adding a Anthropic key unlocks Anthropic models in the model picker for your campaign AI steps: qualification, personalization, segmentation and rewriting. Steps that run on a Anthropic model use your key, cost 0 Ken credits, and Anthropic bills your account for the tokens.

If your key stops working, Ken runs the step on its default model and charges credits, unless you turn Ken fallback off. Then the step waits until your key works again.

What Syncs

In short One-way: Ken calls Anthropic with your key.
