Why Wishlist Member API sometimes do not work?
Wishlist Member external API is calling a specific URL that’s designed by Wishlist Member to accept API requests. In order not to accept just any request Wishlist Member need to authenticate the API call using the Wishlist Member API Key (which is defined in the Wishlist Member settings). After the API connection is established and authenticated an API request can be made.
The Wishlist Member API call can fail from the main following reasons:
<ol>
<li>The API was not authenticated correctly.</li>
<li>The API call is getting a result from the cache and only the first API call succeed and all the following calls will fail.</li>
<li>Plugin conflict with caching or security plugins that are installed on the WordPress installation or on your server. These plugins prevent the URL call and cause the API request to fail.</li>
<li>Server or PHP settings that prevent the API from being authenticated correctly.</li>
<li>DNS servers or CDN services than can cache or redirect the API URL to an incorrect URL, causing the Wishlist Member API not to be authenticated correctly and fail.</li>
</ol>
These are only few of the reasons that can cause a problem. Because it’s impossible to predict the results or isolate the cause in all cases we have created this plugin which identify that there is some kind of problem with the Wishlist Member external API.
