It takes effect for that org only; other orgs keep the built-in. Two boundaries cannot be crossed here. Overriding a built-in INHERITS its category and its counsel-review posture, which can be raised but never dropped; and a formation or equity template is counsel-review whatever the caller sends, so no org can generate a securities-class document without the notice. The body is validated on save, not at generation: a template that references an UNDECLARED merge field is refused with 400 rather than stored and rendered blank into a contract months later. ## Request 9 fields, body `application/json` (required). | Field | In | Type | Required | Description | | ---------------- | ---- | -------------- | -------- | ----------------------------------------------------------------------------------------------------- | | `id` | path | string | yes | ID is the template to override, from the path. | | `body` | body | string | — | Body is the text/template source. | | `category` | body | string | — | Category groups the template: formation, equity, ops or sales. | | `counselReview` | body | boolean | — | CounselReview marks a template whose documents must carry the counsel notice. | | `fields` | body | legal.Field\[] | — | Fields declares the merge fields the body consumes. | | `fields[].key` | body | string | — | Key is the identifier the body substitutes ({{.key}}) and the key a generation's data map must carry. | | `fields[].label` | body | string | — | Label is the human prompt for whoever fills the value in — "Governing law (state)". | | `id` | body | string | — | ID is the template to override, from the path. | | `title` | body | string | — | Title is the template's display name. | ## Response | Status | Body | Meaning | | --------- | ------------------- | ------- | | `200` | legal.templateReply | ok | | `default` | problem-details | refused | `200` body — 12 fields. | Field | In | Type | Always | Description | | ------------------------- | ---- | ------------------- | ------ | ----------------------------------------------------------------------------------------------------- | | `disclaimer` | body | string | — | Disclaimer is the boundary made visible on the wire. | | `template` | body | legal.legalTemplate | — | | | `template.body` | body | string | — | | | `template.category` | body | string | — | | | `template.counselReview` | body | boolean | — | | | `template.fields` | body | legal.Field\[] | — | | | `template.fields[].key` | body | string | — | Key is the identifier the body substitutes ({{.key}}) and the key a generation's data map must carry. | | `template.fields[].label` | body | string | — | Label is the human prompt for whoever fills the value in — "Governing law (state)". | | `template.id` | body | string | — | | | `template.origin` | body | string | — | | | `template.title` | body | string | — | | | `template.version` | body | integer (int64) | — | | Failure carries the platform error shape — see [Errors](https://docs.hanzo.ai/docs/errors). ## Examples **CLI** ```bash hanzo legal templates set ``` **SDK** **.ts** ```ts import { Configuration, LegalApi } from 'hanzoai'; const api = new LegalApi(new Configuration({ accessToken: process.env.HANZO_API_KEY })); const { data } = await api.putLegalTemplatesById({ id: 'id', body: "", category: "" }); ``` **.py** ```python from hanzoai.cloud import ApiClient, Configuration from hanzoai.cloud.api import LegalApi client = ApiClient(Configuration(access_token=os.environ["HANZO_API_KEY"])) result = LegalApi(client).put_legal_templates_by_id(id='id', body="", category="") ``` **.go** ```go cfg := hanzoai.NewConfiguration() cfg.AddDefaultHeader("Authorization", "Bearer "+os.Getenv("HANZO_API_KEY")) client := hanzoai.NewAPIClient(cfg) resp, _, err := client.LegalAPI.PutLegalTemplatesById(context.Background()).Execute() if err != nil { return err } ``` **.rs** ```rust use hanzo_client::apis::{configuration::Configuration, legal_api}; let mut cfg = Configuration::new(); cfg.bearer_access_token = std::env::var("HANZO_API_KEY").ok(); let result = legal_api::put_legal_templates_by_id(&cfg, Default::default()).await?; ``` **.java** ```java import ai.hanzo.cloud.ApiClient; import ai.hanzo.cloud.api.LegalApi; ApiClient client = new ApiClient(); client.setBearerToken(System.getenv("HANZO_API_KEY")); var result = new LegalApi(client).putLegalTemplatesById(); ``` **HTTP** ```bash curl -X PUT https://api.hanzo.ai/v1/legal/templates/ \ -H "Authorization: Bearer $HANZO_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "body": "", "category": "" }' ``` **MCP** MCP reaches **legal** through the `legal` tool, which names its 10 operations with its own verbs — this one among them, under a name only MCP declares. `describe` explains any of them: ```bash curl -X POST https://api.hanzo.ai/v1/mcp \ -H "Content-Type: application/json" \ -d '{ "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "describe", "arguments": { "op": "list_legal_documents" } } }' ``` --- [Legal API](https://docs.hanzo.ai/docs/openapi/legal) · [All Hanzo APIs](https://docs.hanzo.ai/docs/openapi) · [Interactive reference](https://docs.hanzo.ai/docs/openapi/reference)
