A field left out keeps its value; an empty string clears a sender field back to the org's. Org admin only. ## Request 15 fields, body `application/json` (required). | Field | In | Type | Required | Description | | ------------- | ---- | ------- | -------- | ------------------------------------------------------------------------------------------------- | | `id` | path | string | yes | ID is the list to change, from the path; ignored on create. | | `company` | body | string | — | Company is the sender's legal name in the footer; at most 200 characters. | | `description` | body | string | — | Description says what subscribers receive; at most 2000 characters. | | `doubleOptIn` | body | boolean | — | DoubleOptIn is whether a public subscription must be confirmed; a new list asks for confirmation. | | `footer` | body | string | — | Footer is text closing every mail of the list; at most 2000 characters. | | `fromAddress` | body | string | — | FromAddress is the sender's address. | | `fromName` | body | string | — | FromName is the sender's name; at most 200 characters. | | `id` | body | string | — | ID is the list to change, from the path; ignored on create. | | `language` | body | string | — | Language is a BCP 47 tag; a new list takes the platform's default. | | `name` | body | string | — | Name is what the list is called. | | `postal` | body | string | — | Postal is the sender's physical postal address; at most 500 characters. | | `provider` | body | string | — | Provider is ses, sendgrid, or empty for the org's own. | | `replyTo` | body | string | — | ReplyTo is where replies go. | | `slug` | body | string | — | Slug is the list's name in a URL: lower-case letters, digits and hyphens, at most 63. | | `visibility` | body | string | — | Visibility is public or private; a new list is private. | ## Response | Status | Body | Meaning | | --------- | --------------- | ------- | | `200` | marketing.List | ok | | `default` | problem-details | refused | `200` body — 18 fields. | Field | In | Type | Always | Description | | ------------- | ---- | --------------- | ------ | -------------------------------------------------------------------------------------------------------------------------------- | | `company` | body | string | — | Company is the sender's legal name in the footer; empty takes the org's. | | `counts` | body | object | — | Counts are the list's subscribers by status. | | `counts.*` | body | integer (int64) | — | | | `createdAt` | body | integer (int64) | — | CreatedAt is when the list was created, unix seconds. | | `description` | body | string | — | Description says what subscribers receive. | | `doubleOptIn` | body | boolean | — | DoubleOptIn is whether a public subscription waits for the address to confirm before it is subscribed. | | `footer` | body | string | — | Footer is text closing every mail of the list, above the unsubscribe line. | | `fromAddress` | body | string | — | FromAddress is the sender's address; empty takes the org's. | | `fromName` | body | string | — | FromName is the sender's name on the list's mail; empty takes the org's. | | `id` | body | string | — | ID is the list's id ("lst\_" and 96 random bits in hex). | | `language` | body | string | — | Language is the list's language, a BCP 47 tag. | | `name` | body | string | — | Name is what the list is called. | | `postal` | body | string | — | Postal is the sender's physical postal address, which every commercial mail carries (CAN-SPAM); empty takes the org's. | | `provider` | body | string | — | Provider is ses or sendgrid; empty takes the org's. | | `replyTo` | body | string | — | ReplyTo is where replies go; empty takes the org's. | | `slug` | body | string | — | Slug is the list's name in a URL, unique in the org: a public form may name the list by it ("newsletter"). | | `updatedAt` | body | integer (int64) | — | UpdatedAt is the last change to the list itself, unix seconds. | | `visibility` | body | string | — | Visibility is public, which the public subscribe and the preference page offer, or private, which only the org's own calls fill. | Failure carries the platform error shape — see [Errors](https://docs.hanzo.ai/docs/errors). ## Examples **CLI** ```bash hanzo marketing lists update ``` **SDK** **.ts** ```ts import { Configuration, MarketingApi } from 'hanzoai'; const api = new MarketingApi(new Configuration({ accessToken: process.env.HANZO_API_KEY })); const { data } = await api.patchMarketingListsById({ id: 'id', company: "", description: "" }); ``` **.py** ```python from hanzoai.cloud import ApiClient, Configuration from hanzoai.cloud.api import MarketingApi client = ApiClient(Configuration(access_token=os.environ["HANZO_API_KEY"])) result = MarketingApi(client).patch_marketing_lists_by_id(id='id', company="", description="") ``` **.go** ```go cfg := hanzoai.NewConfiguration() cfg.AddDefaultHeader("Authorization", "Bearer "+os.Getenv("HANZO_API_KEY")) client := hanzoai.NewAPIClient(cfg) resp, _, err := client.MarketingAPI.PatchMarketingListsById(context.Background()).Execute() if err != nil { return err } ``` **.rs** ```rust use hanzo_client::apis::{configuration::Configuration, marketing_api}; let mut cfg = Configuration::new(); cfg.bearer_access_token = std::env::var("HANZO_API_KEY").ok(); let result = marketing_api::patch_marketing_lists_by_id(&cfg, Default::default()).await?; ``` **.java** ```java import ai.hanzo.cloud.ApiClient; import ai.hanzo.cloud.api.MarketingApi; ApiClient client = new ApiClient(); client.setBearerToken(System.getenv("HANZO_API_KEY")); var result = new MarketingApi(client).patchMarketingListsById(); ``` The method above is the one at the current release of the document. `hanzoai@8.5.914` (npm) and `hanzoai@8.5.914` (PyPI) were generated from an earlier release, where this operation carried a different id, so it spells the method differently — regenerating the clients is what makes the two agree.
