# Update an email template

`PATCH /email_templates/{id}`

Updates one or more fields of the specified email template and returns the updated template.

## Path parameters

- `id` string, uuid, required

## Request body

- UpdateEmailTemplateRequest
  - `name` string
  - `subject` string, nullable — Liquid template subject.
  - `html_body` string, nullable — Liquid template HTML body.
  - `text_body` string, nullable — Liquid template text body.
  - `variables` string[]
  - `strict_variables` boolean — Per-template strict variable-validation setting.
  - `autoescape` boolean — Per-template HTML autoescaping setting.
  - `variable_schema` object, nullable — Structured variable requirements. Required variables cannot define defaults; invalid combinations return 422. Set to `null` to clear the schema.

## Response `200`

Template updated.

- EmailTemplateResponse
  - `data` EmailTemplate, required
    - `record_type` 'email_template', required
    - `id` string, uuid, required
    - `name` string, required
    - `subject` string, nullable, required
    - `html_body` string, nullable, required
    - `text_body` string, nullable, required
    - `variables` string[], required — Legacy unstructured variable names. This path remains supported unchanged.
    - `strict_variables` boolean, required — Whether strict variable validation is enabled for this template. When `true`, sends and renders that are missing a variable marked `required: true` in `variable_schema` fail with 422 naming the variable.
    - `autoescape` boolean, required — Whether HTML autoescaping is enabled for this template. When `true`, only rendered `html_body` expression output is HTML-escaped at the output boundary; `subject` and `text_body` are never autoescaped.
    - `variable_schema` object, nullable, required — Structured variable requirements, or `null` when the template uses only the legacy `variables` array.
    - `created_at` string, date-time, required
    - `updated_at` string, date-time, required

## Other responses

- `401` — Not authorized (10006).
- `404` — Resource not found (10001).
- `422` — Validation Failed (10015) or changeset validation error.
