How my students can pay for their courses.
Hi Farid! Welcome to Heroes!
You might find this discussion interesting; it features learning management systems that have e-commerce options if you are looking to sell your e-learning content. If you are planning on hosting your courses on Articulate Online, you might also be interested in the Articulate Online API which will allow your Articulate Online content communicate with other programs, such as a front-end e-commerce setup.
You can ask questions in those discussions and reach out to the other members directly through their profiles. I hope that helps to get you in the right direction!
