AWS Lambda Integration

Serverless compute that runs your code without managing servers. Connect AWS Lambda events to the tools your engineering teams already use. Start with Watch Durable Executions, then follow with Get Account Settings or Get Alias to automate the next step.

How to integrate AWS Lambda in automation workflow?

3 simple steps to make your AWS Lambda connected with other apps in automation workflows on WEXTL. Up to 10 minutes integration set up.

STEP 1

Select AWS Lambda in workflow

Pick AWS Lambda app in the workflow builder [4] - just one click to select the app.

STEP 2

Connect AWS Lambda

When prompted, authorize access to AWS Lambda in WEXTL once. AWS Lambda credentials are encrypted and never shared with WEXTL. Authorization will be reused in any future API calls [3].

WEXTL wants to integrate with your AWS Lambda account. Approve?

STEP 3

Build a workflow

Build your workflow with AWS Lambda yourself or with WEXTL® AI Builder. Connect AWS Lambda to any available integrations [5], or use HTTP node to go beyond them.

AWS Lambda

How AWS Lambda connects and integrates with WEXTL

Save and approve your credentials once — WEXTL® stores authorization information encrypted and reuses the authentication whenever AWS Lambda app is called in workflows. That allows your developer tools automations to run without your attention, per defined schedule [7]. Explore documentation [6] for a detailed list of fields that AWS Lambda supports.

Full AWS Lambda API documentation

The following table illustrates what fields AWS Lambda integration require during authorization flow inside our workflow builder [4].

Demonstration of AWS Lambda connection step inside WEXTL Workflow Builder [4].

Field	Type	Help
Access Key IDRequired	text	The access key ID of an IAM user or role. Verifying the connection needs permission to read account settings (lambda:GetAccountSettings).
Secret Access KeyRequired	password	Stored encrypted. Treat it like a password.
RegionRequired	text	The Region your functions live in, for example us-east-1. Every request goes to this Region.
ServiceRequired	select	Leave as lambda. It is needed so requests can be signed.
Session Token	password	Only for temporary credentials.

Connect AWS Lambda to popular apps on WEXTL

Enter a name of the other app you want to sync with AWS Lambda below. Click on selected app to explore integration options with AWS Lambda. If the app you search for is not available in WEXTL yet, you can use HTTP node [10] instead to integrate it directly.

Example automation with AWS Lambda integration

Select Watch Durable Executions trigger from AWS Lambda - this will be a starting point in your automation. Whenever event happens in AWS Lambda, workflow will start [7] from Watch Durable Executions node.

Search for Create Durable Execution Checkpoint, connect it as the next step of integration sequence. You can use filters between Watch Durable Executions and Create Durable Execution Checkpoint, so only important data pass from Watch Durable Executions to the next step. WEXTL gives you full control over the process of AWS Lambda automation. All parts of workflow are visible on the canvas [4].

AWS Lambda on WEXTL has 88 modules for creating developer tools automations. Explore AWS Lambda documentation for more.

Frequently asked questions

Common questions about automating AWS Lambda in your workflows.

AWS Lambda has 1 trigger, including "Watch Durable Executions". Triggers are start points of the workflow, and automations may start from them.

Integration has 87 actions, including "Get Account Settings", "Get Alias", and "Get Capacity Provider", and more. Refer to our AWS Lambda Documentation for detailed inputs and outputs.

No. Most automations are built visually on the canvas by picking triggers, actions, and mapping fields. You can add custom JavaScript with Functions when advanced logic is needed — but our customers do that in rare cases [4].

Yes. Connections are authenticated per account, credentials are encrypted at rest, and you can enforce approvals and team-level access controls on any automation.

The AWS Lambda integration on WEXTL runs directly on its vendor public API — every field name, authentication method, and rate limit is controlled by AWS Lambda official API and covered in documentation [3]. WEXTL handles the request signing and pagination for you.

Absolutely. Where AWS Lambda provides native webhooks, you can use instant triggers to eliminate polling delay. For custom webhooks, WEXTL offers Custom Webhook node, so you can start automation whenever AWS Lambda or any other service sends event to webhook URL.

WEXTL is an AI-first visual canvas. The platform allows you to describe automation in plain text — and AI will wire nodes for AWS Lambda inside the workflow builder [4]. You can also use built-in workflow nodes (AI Agent, Human in the Loop, Condition, Aggregate Results) in pair with AWS Lambda modules to craft complex integration flows with branches, filtering, and conditional logic. There are absolutely no limits of what you can build.
