# Integrations

> Connect FlowSign to Zapier, n8n, Make and Power Automate.

Every platform below works with FlowSign today through the public API and webhooks, using nothing but that platform's own HTTP and webhook steps. No FlowSign app needs to be installed.

Calling the API needs a Bearer API key (`fsk_...`); create one at **Settings > API keys** ([my.flowsign.app/settings/api-keys](https://my.flowsign.app/settings/api-keys)). See [Authentication](/api-reference/authentication). Receiving events needs a webhook endpoint at **Settings > Webhooks** instead, no API key required; see [Webhooks](/webhooks/overview).
