Address	`https://api.hanzo.ai/v1/tax/forms/{id}/furnish`
Method	`POST`
Operation	`post_tax_forms_by_id_furnish`
Auth	`Authorization: Bearer $HANZO_API_KEY`

Furnishes Copy B of a reviewed 1099 to its payee. Org admins only.

When the payee's tax profile consents to electronic delivery, Copy B is delivered into the payee's /v1/tax/inbox and the form is furnished. Otherwise it is OWED on paper at the payee's address: mailing it is the payer's, and POST /v1/tax/forms/{id}/mailed records it. Either way the statement is final from this call — the form can no longer change, only be corrected. Calling it again on a form furnished electronically re-delivers Copy B if the inbox lacks it, and changes nothing else.

It does not file anything with the IRS, and it does not send the notice of posting Pub 1099 Part M asks a furnisher to give an electronic recipient; the statement is in the recipient's inbox, and telling them so is the payer's.

Examples

hanzo has no subcommand for this operation — the CLI serves only what cloud's live route table confirms. Use HTTP or an SDK.

import { Configuration, TaxApi } from 'hanzoai';

const api = new TaxApi(new Configuration({ accessToken: process.env.HANZO_API_KEY }));
const { data } = await api.postTaxFormsByIdFurnish({ id: 'id' });

from hanzoai.cloud import ApiClient, Configuration
from hanzoai.cloud.api import TaxApi

client = ApiClient(Configuration(access_token=os.environ["HANZO_API_KEY"]))
result = TaxApi(client).post_tax_forms_by_id_furnish(id='id')

cfg := hanzoai.NewConfiguration()
cfg.AddDefaultHeader("Authorization", "Bearer "+os.Getenv("HANZO_API_KEY"))
client := hanzoai.NewAPIClient(cfg)

resp, _, err := client.TaxAPI.PostTaxFormsByIdFurnish(context.Background()).Execute()
if err != nil {
	return err
}

use hanzo_client::apis::{configuration::Configuration, tax_api};

let mut cfg = Configuration::new();
cfg.bearer_access_token = std::env::var("HANZO_API_KEY").ok();

let result = tax_api::post_tax_forms_by_id_furnish(&cfg, Default::default()).await?;

import ai.hanzo.cloud.ApiClient;
import ai.hanzo.cloud.api.TaxApi;

ApiClient client = new ApiClient();
client.setBearerToken(System.getenv("HANZO_API_KEY"));

var result = new TaxApi(client).postTaxFormsByIdFurnish();

The method above is the one at the current release of the document. [email protected] (npm) and [email protected] (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.
