An API, or Application Programming Interface, is a set of tools and protocols used for building application software. It is a set of clearly defined communication methods between various components of a software program. An API makes it simpler to develop computer software, and provides all the building blocks for the programmer to put together.

    En este momento tengo un sitio de membresía que usaba MemberPress. Estoy harto de pagar anualmente por tantos plugins distintos, sobre todo cuando ya hoy en día puedo cubrir lo que necesito con una combinación de Woocommerce, Learndash y Divi, y dejar de usar MemberPress. El problema: tengo más de 50 personas pagando mensualmente con MemberPress (y su interacción con Stripe). A través de las API de Memberpress, Learndash y Woocommerce (que son extensas) se puede hacer esta transición de Memberpress a Woocommerce para la parte de pagos, y Leandash y/o Divi para la parte de membresía. Los detalles de cómo "esconder" contenido de membresías, ya sea con Learndash o con Divi, serán definidas de acuerdo co...
