AWS Step Functions

Workflow orchestration on AWS: state machines, executions, activities, and task tokens

Signs in with: AWS access keys
Runs on: Cloud or On-Prem Worker
Operations: 37
Ready-made triggers: 0

Connect AWS Step Functions

In Neblex open Connect › Connections and click New Connection.
Search for AWS Step Functions and give the connection a clear name.
Fill in the fields. Secret values are encrypted and never shown again.
Click Test, then Create Connection.

Field	What to enter
Access key IDRequiredSecret	The access key ID of an IAM user or role session.
Secret access keyRequiredSecret	The secret access key that belongs to the access key ID.
Session tokenOptionalSecret	Only for temporary credentials (an assumed role or federated session).
RegionRequired	The AWS Region of the state machines, for example us-east-1.Example: `us-east-1`

Use it in a flow

Open a flow, open the node library and search for AWS Step Functions.
Drag it onto the canvas and choose an Operation and your connection.
Map the operation's fields from earlier steps, or click Map with Matt.
Use Test this step to see what it returns, then save.

To start a flow from AWS Step Functions without a ready-made trigger: a Poll for changes trigger can check one of its list operations on a schedule and pass on only what is new; if AWS Step Functions can send webhooks, a Webhook trigger receives them at its own URL.

Operations

37 operations in 7 groups. Each one is a step you can add to a flow.
