A better version of the WishList Member API. Created to make the connection to external services like ActiveCampaign and Autorespond a lot easier. Also gives option to send email notifications after succesfully adding an user through the API. This version is currently only available in the Dutch language. A translation to English is in the works. With this plugin you have the option to: Force the API to check if the user already exists. With the original Simple WLM API in combination with an external service, the user is often not recognized as existing user. As a result, the Autoresponder tries to add a new user, which will fail. Better WishList API will check if the user exists, and, if so, overrules the Autoresponder’s request to create a new user. Instead, it will add the level to the existing user. Get notifications by email of added users and levels. This way you don’t have to check if a transaction completed succesfully. Also register your user’s first name and last name. The original Simple WLM API is not able to handle the user’s name Log requests and see the results This plugin also gives you detailed instructions how to use the API in conjunction with Autorespond en ActiveCampaign.
