You need an AWS account with IAM permissions to create users and access keys (administrator access or an equivalent IAM policy).

​
Create an IAM user

Create a dedicated IAM user for StackOne so its access can be managed and revoked independently of your own.

1

Sign in to AWS

Sign in to your AWS IAM console.

  • Navigate to Users > Create user.
2

Set the user name

Enter a name for the user and continue.

  • Example: stackone-lambda
  • Click Next.
3

Attach permissions

Grant the user access to Lambda.

  • Select Attach policies directly.
  • Attach AWSLambda_FullAccess, or a custom policy scoped to only the Lambda actions you need.
  • Click Next, then Create user.

​
Create an access key

Generate the Access Key ID and Secret Access Key that StackOne uses to sign requests.

1

Open the user's security credentials

From Users, select the user you just created and open the Security credentials tab.

  • Under Access keys, click Create access key.
2

Choose a use case

Select Third-party service as the use case.

  • Acknowledge the recommendation, then click Next.
  • (Optional) Add a description tag, then click Create access key.
3

Copy the Access Key ID and Secret Access Key

Copy both values and store them securely for use later.

  • Access Key ID format: AKIAIOSFODNN7EXAMPLE
  • The Secret Access Key is shown only once — if you lose it, delete the access key and create a new one.
  • Optionally click Download .csv file to save both values.

​
Find your AWS Region

Your AWS Region determines which regional Lambda endpoint StackOne connects to. Use the Region that hosts your functions.

  • Check the Region selector in the top-right of the AWS console.
  • Enter the Region code, not the display name
  • Example: US East (N. Virginia) is us-east-1, and Europe (London) is eu-west-2

​
Linking the Account from the Hub

1

Navigate to the Hub

Use one of the three Linking Account Methods to access the Hub.
2

Fill out the fields

Fill out the following fields using details from your provider:
  • Access Key ID
  • Secret Access Key
  • AWS Region
3

Connect

  • Click Connect
  • If applicable, the provider will redirect you to a sign-in or authorization page. Complete the provider’s authorization flow.
  • Once authorization is successful, you will see a confirmation popup

If the account linking is successful, you will see the newly linked account in your Accounts page.
