<tr><th>
Browsers
</th><tdwidth=100%>
Load <code>@octokit/endpoint</code> directly from <ahref="https://cdn.skypack.dev">cdn.skypack.dev</a>
You can pass `requestOptions` to common request libraries
```js
const { url, ...options } = requestOptions;
// using with fetch (https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API)
fetch(url, options);
// using with request (https://github.com/request/request)
request(requestOptions);
// using with got (https://github.com/sindresorhus/got)
got[options.method](url, options);
// using with axios
axios(requestOptions);
```

All other options will be passed depending on the `method` and `url` options.
1. If the option key has a placeholder in the `url`, it will be used as the replacement. For example, if the passed options are `{url: '/orgs/{org}/repos', org: 'foo'}` the returned `options.url` is `https://api.github.com/orgs/foo/repos`.
2. If the `method` is `GET` or `HEAD`, the option is passed as a query parameter.
3. Otherwise, the parameter is passed in the request body as a JSON key.
**Result**
`endpoint()` is a synchronous method and returns an object with the following keys:

Stateless method to turn endpoint options into request options. Calling
`endpoint(options)` is the same as calling `endpoint.parse(endpoint.merge(options))`.
## Special cases
<aname="data-parameter"></a>
### The `data` parameter – set request body directly
Some endpoints such as [Render a Markdown document in raw mode](https://developer.github.com/v3/markdown/#render-a-markdown-document-in-raw-mode) don’t have parameters that are sent as request body keys, instead, the request body needs to be set directly. In these cases, set the `data` parameter.
```js
const options = endpoint("POST /markdown/raw", {
data: "Hello world github/linguist#1 **cool**, and #1!",
headers: {
accept: "text/html;charset=utf-8",
"content-type": "text/plain",
},
});
// options is
// {
// method: 'post',
// url: 'https://api.github.com/markdown/raw',
// headers: {
// accept: 'text/html;charset=utf-8',
// 'content-type': 'text/plain',
// 'user-agent': userAgent
// },
// body: 'Hello world github/linguist#1 **cool**, and #1!'
// }
```
### Set parameters for both the URL/query and the request body
There are API endpoints that accept both query parameters as well as a body. In that case, you need to add the query parameters as templates to `options.url`, as defined in the [RFC 6570 URI Template specification](https://tools.ietf.org/html/rfc6570).
