In Workflows (Via Agent Node)

For automated pipelines, use an Agent Node with Similarweb tools. This gives you the flexibility of an agent within a deterministic workflow.

Authentication

Similarweb uses OAuth 2.0 for authentication. When you connect the integration, you’ll be redirected to Similarweb to authorize access. No API keys or manual configuration required.
