# Get template variables preview

GET https://connect.chatbridge.mx/v1/rcs/templates/vars/{templateId}

Returns the variables the template requires — with an example value per variable — plus a `body_example` ready to use in `POST /v1/rcs/messages`. Useful to build a send form dynamically without parsing the template structure.

The type of each variable is inferred from where it appears in the template: variables placed in `fileUrl`, `thumbnailUrl`, `iconUrl`, or `url` are of type **URL** (they must be valid `http`/`https` URLs and the referenced media is validated with a real HEAD request — MIME type and size); any other variable is free **TEXT**.

Reference: https://docs.chatbridge.mx/rcs/templates/get-rcs-template-vars

## Authentication

- `x-api-key` header (required) — Account authentication key. The App-Key must have the RCS channel enabled.
- `Authorization` header (bearer token, required) — OAuth 2.0 access token issued by `POST /api/oauth/token` (client-credentials). Takes precedence over `x-api-key` when both are sent. See the Authentication section.

## Request

### Path parameters

- `templateId` (string, required) — Template identifier.

## Response

### 200

Variables required by the template and example send body.

- `template_id` (string, optional)
- `type` (enum, optional) — RCS content type. The agent's type must match the template's type when sending.
  - Allowed values: `BASIC`, `SINGLE`, `CONVERSATIONAL`
- `variables` (map from string to string, optional) — Map `{ variable: example_value }`. Empty `{}` if the template has no variables. URL-type variables (those placed in `fileUrl`/`thumbnailUrl`/`iconUrl`/`url`) show a URL example and must be valid `http`/`https` URLs when sending; the rest are free text.
- `body_example` (map from string to any, optional) — Ready-to-use body for `POST /v1/rcs/messages`.
