health API should use documented API GET /validatesignature
https://laterpay.net/developers/docs/backend-api/#GET/validatesignature

get_controls_balance_url is NOT deprecated as stated in https://github.com/laterpay/laterpay-client-php/blob/develop/LaterPay/Client.php#L239

Instead, it is the method that should be used instead of the deprecated get_iframe_api_balance_url, see https://github.com/laterpay/laterpay-client-python/blob/develop/laterpay/__init__.py#L172

Please also add an according hint to the PHP client, which API method to use, as done in the Python client.

According to compatibility check we need to remove deprecated php 4 constructors.

We should recheck if all methods from Python client ported to php

add functionality to check LP API health

We absolutely have to do that and soon. laterpay/laterpay-wordpress-plugin#3 doesn't really factor into this, because HOW the client ends up in the wordpress-plugin is really not that interesting to me. If we have to copy new versions manually... fine.

However, I just tried to build an example for a customer out of the LaterPay client, and realized that that's impossible because the client is now completely polluted by WordPress references (in particular wp_remote_retrieve_body and get_option).

I previously was under the impression that we had specifically built an abstraction between the different ways to perform HTTP requests in PHP. Why that was replaced with WordPress-specific code without fallbacks... I don't know. In any case, we should resurrect that previous code and build on it:

• The client should select a HTTP call method available to it, be it fopen, curl or wget or wordpress wp_*. WordPress in that sense is really just a backend.
• The client should never reference WordPress configuration or WordPress-plugin constants. These should be passed into the client from the calling code in the WordPress-plugin.

The client should be minimal and have a trusted PHP 5.2-compatible loading method, which likely means a single file that can be require_onced that loads all dependencies. The current SPL-based autoloader seems much too magic to me (e.g. replacing "_" in classnames with path separators to figure out where a source file is). We can ship such magic in the WordPress-Plugin, but I'd rather not ship it in the PHP client.

However that returned a

{"status": "error", "message": "Wrong signature: \"e6e3c89e268b422fd41494dfe41f2f16ee0709589aaa798f9c938b5e\"", "http_status": 403}

Using the official Python client, for the same parameters, I generated this URL

Obviously the article_id parameter is sorted differently. This is because 8 is greater than 32 (8 > 32) in string sort.
