# Create project service account

`POST /organization/projects/{project_id}/service_accounts`

## Request

- Base URL: `https://api.openai.com/v1`
- URL: `https://api.openai.com/v1/organization/projects/{project_id}/service_accounts`
- Auth: HTTP bearer

Creates a new service account in the project. By default, this also returns an unredacted API key for the service account.

## Path parameters

- `project_id` string, required

## Request body

- ProjectServiceAccountCreateRequest
  - `name` string, required: The name of the service account being created.
  - `create_service_account_only` boolean, nullable: Create the service account without default roles or an API key.
  - `expires_in_seconds` integer, nullable: Number of seconds until the initial API key expires. If omitted or null, the key does not expire unless the effective organization or project policy requires an expiration. When a policy sets a maximum lifetime, this value must be provided and must not exceed that limit. A non-null value cannot be used when `create_service_account_only` is true.

## Response `200`

Project service account created successfully.
