Can I use external links to 3rd party apps?

[Jaime]

Hola, newby here!

I have lots of content material uploaded to Quizlet & Quizizz.

Can I include them as part of my new course or would I infringe anything?

And also, can I invite my students to join my private Facebook group to submit work and engage with the community?

Gracias.

Hi there @Jaime , welcome to the community! You can create a bonus lecture to add external links. Here are the rules and guidelines for more information: https://support.udemy.com/hc/en-us/articles/229232847-Bonus-Lecture-Rules-and-Guidelines

With regards to your 2nd question, you can contact the team at policy@udemy.com, they'll tell you what is allowed and what isn't on the platform.

Hope this helps!
