# Requests

Data sent must be properly [UTF-8](https://en.wikipedia.org/wiki/UTF-8) URL-encoded. By default, browsers will properly encode `POST` calls. However, if you are writing your own client, you will need to make sure to set the `HTTP Content-Type header` to `application/x-www-form-urlencoded` if you are [form-encoding](https://en.wikipedia.org/wiki/POST_\(HTTP\)#Use_for_submitting_web_forms) your request bodies or `application/json` if you are [JSON-encoding](http://www.json.org/) your request bodies. If you are uploading a file as part of your request, you will need to specify `multipart/form-data`.

In some cases, clients do not support `PUT` and `DELETE` methods. In these cases, you can override the actual `HTTP` method by appending the `_method` parameter via a `POST` request. Valid values are `PUT` and `DELETE`.

Unless otherwise stated, request parameters have the following restrictions:

| Type       | Restriction                                                                           |
| ---------- | ------------------------------------------------------------------------------------- |
| *string*   | 255 `UTF-8` characters                                                                |
| *decimal*  | 8 digits, 2 decimal places                                                            |
| *datetime* | [ISO-8601](https://en.wikipedia.org/wiki/ISO_8601) (e.g. `2020-10-09T10:30:01−07:00`) |
| *currency* | [ISO-4217](https://en.wikipedia.org/wiki/ISO_4217) (e.g. `USD`)                       |
| *integer*  | 16 digits                                                                             |
