End-user guide to authorize the integration and start using Terraform actions. Admin or Owner privileges are required in your Terraform account to generate API tokens.

Determine Your Terraform Host

Identify your Terraform instance host based on your deployment type. This is the value you enter in the Terraform Host field in StackOne Hub.

Your Terraform Host depends on whether you use Terraform Cloud or Terraform Enterprise.

  • Terraform Cloud - Use `https://app.terraform.io`
  • Terraform Enterprise - Use your self-hosted instance URL
  • Format: `https://{your-instance}.example.com`
  • Example: `https://terraform.yourcompany.com`
  • Paste this value into the Terraform Host field in StackOne Hub.

Generate an API Token

Create a user API token to authenticate with the Terraform API.

Sign in to your HCP Terraform account or your Terraform Enterprise instance, then open your account settings.

  • Click your user icon in the top-right corner
  • Select Account settings

In the Account Settings sidebar, click Tokens, then click Create an API token.

The Tokens page under Account Settings with the Create an API token button highlighted

In the Creating a user token dialog, fill in the details and generate the token.

  • Enter a Description to help you identify this token later (e.g. `StackOne Integration`)
  • Choose an Expiration for the token (the default is 30 days)
  • Click Generate token
The Creating a user token dialog with the Description and Expiration fields and the Generate token button highlighted

After you click Generate token, the new token is displayed inline on the Tokens page. Copy it and store it securely for use in StackOne.

  • Copy the token from the Tokens page immediately using the copy button next to it
  • HCP Terraform will not display this token again, so store it securely. The token is shown once and cannot be retrieved later — if you lose it, you must delete it and create a new one.
  • Paste the token into the API Token field in StackOne Hub.

Linking the Account from the Hub

Use one of the three Linking Account Methods to access the Hub. Fill out the following fields using details from your provider:
  • Terraform Host
  • API Token
  • 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.
