Getting Started

Create a workflow to AWS - Lambda - Invoke Function with the AWS API. When you configure and deploy the workflow, it will run on Pipedream's servers 24x7 for free.

  1. Configure the AWS - Lambda - Invoke Function action
    1. Connect your AWS account
    2. Configure AWS Region
    3. Configure Lambda Function Name
    4. Configure Event data
  2. Select a trigger to run your workflow on HTTP requests, schedules or app events
  3. Deploy the workflow
  4. Send a test event to validate your setup
  5. Turn on the trigger

Lambda Function NameFunctionNamestring

The name of your Lambda function. Also accepts a function ARN

Event dataeventDatastring

Authentication

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

Follow the AWS Instructions for creating an IAM user with an associated access and secret key.

As a best practice, attach the minimum set of IAM permissions necessary to perform the specific task in Pipedream. If your workflow only needs to perform a single API call, you should create a user and associate an IAM group / policy with permission to do only that task. You can create as many linked AWS accounts in Pipedream as you'd like.

Once done, enter your access and secret key below.
