How do I call an AWS Lambda function?

Short answer: You can invoke lambda function in AWS Lambda by hand from its own interface, but it won’t repeat itself. On TinyCommand, add the AWS Lambda Invoke Lambda Function action to a workflow, map its 4 inputs from any upstream app, and it runs automatically every time the trigger fires. No code, and a free tier to start.

Inputs

The fields this action accepts.

Every field can be mapped from an upstream trigger, AI step, table row, or hard-coded literal.

FieldTypeRequiredDescription
Function Name or ARN
function_name
stringRequiredLambda function name, partial ARN, or full ARN. Function must exist in the connected region.
Event Payload
payload
objectOptionalJSON event the function receives. Whatever your handler expects.
Invocation Type
invocation_type
optionsOptional–
Version or Alias
qualifier
stringOptionalOptional version number or alias. Defaults to $LATEST.
Sample request
{
  "function_name": "my-function OR arn:aws:lambda:us-east-1:123456789012:function:my-function",
  "payload": "{{trigger.payload}}",
  "invocation_type": "{{trigger.invocation_type}}",
  "qualifier": "$LATEST"
}
Returns
{
  "body": "{ \"message\": \"Hello from Lambda\" }",
  "statusCode": 200
}

Use these fields in downstream nodes for routing, logging, or error handling.

FAQ

Questions about Invoke Lambda Function.

What does the Invoke Lambda Function action do in AWS Lambda?
Synchronously or asynchronously invokes a Lambda with a JSON payload. Sync waits for the response (up to 15 min, Lambda's max); async returns immediately with an InvocationId for fire-and-forget patterns. The right escape hatch when the workflow needs Python/Node logic that doesn't fit cleanly into a Code step.
What inputs does Invoke Lambda Function require?
Required: Function Name or ARN. Every input accepts a static value or a variable from any upstream node in your workflow.
Can I use dynamic inputs from earlier workflow nodes?
Yes. Any field on this action can pull values from upstream nodes, whether that's a form response, a trigger payload, an AI output, or a lookup result.
What happens if AWS Lambda returns an error?
The workflow pauses on the failed node, the error message is captured in the run log, and you can retry the run with one click. Auto-retry policies are configurable per workflow with exponential backoff up to 5 attempts.
Does Invoke Lambda Function support batch operations?
Yes. Run Invoke Lambda Function inside a Loop node to process arrays. TinyCommand handles AWS Lambda's rate limits automatically so you don't have to throttle manually.
