Action Authentication

Stripe uses API keys for authentication. When you connect your Stripe account, Pipedream securely stores the keys so you can easily authenticate to Stripe APIs in both code and no-code steps.

Stripe uses API keys to authenticate requests (more info in their docs here).

To connect Pipedream to your Stripe account,

  1. Create a Stripe API key
  2. Make sure to create either a Secret or Restricted key
  3. Enter the API key below

To help ensure proper security, we recommend you create a Restricted key, and only allow access to operations you need require in Pipedream.
