Variables & Auth
Use collection-level variables and auth inheritance across your API clusters.
Variable System
Variables let you reuse values across requests. Define them at the cluster level and reference them with {{variableName}} anywhere — URL, headers, params, body, or auth fields.
Defining Variables
Open your cluster's Overview tab (or select a request with the VAR method) to manage variables as key-value pairs:
base_url = https://api.example.com
api_token = your-token-here
version = v2Using Variables
In any request field, type {{base_url}}/users and VortexHQ will resolve it to https://api.example.com/users at send time.
Variables are resolved recursively — a variable can reference another variable.
Authentication
Each request supports four auth modes:
| Mode | Description |
|---|---|
| Inherit | Uses the auth setting from the parent cluster. This is the default. |
| None | No authentication header sent. |
| Bearer Token | Adds Authorization: Bearer {token} header. |
| Basic Auth | Adds Authorization: Basic {base64(user:pass)} header. |
Auth fields support variable interpolation: {{api_token}}. Cluster-level auth is set in the cluster Overview tab and inherited by all requests unless overridden.
