Testimonials from our alumni
Maxim
I never thought I could create my own API from scratch! The course is perfectly structured, from HTTP basics to complex authentication. Especially valuable is that after each section there is a practical assignment. Now I have added 3 working projects to my portfolio!
Anna
Was looking for a course that would explain API not as an abstraction but as a business tool. Learned how to connect payments (Stripe API) and CRM - automated 80% of routine processes in my startup. It paid for itself in a month!
Artem
I was afraid that I wouldn't be able to cope without coding experience, but the lessons on no-code integrations (Zapier + Google Sheets API) were a lifesaver! I set up automatic data upload from advertising offices. Now I save 10 hours a week. Thanks for the quality content!
Olga
I use the course materials for my students - perfect balance of theory and practice. Swagger, Postman, real cases (e.g. working with Twitter API). You can see that the authors are practitioners, not theorists. I recommend it to my colleagues!

Frequently Asked Questions
What knowledge do I need to start learning?
Our API course is designed for beginners - a basic understanding of web technologies and
programming basics is sufficient. You will learn everything you need during the course!
Is the course suitable if I already have experience with APIs?
Yes! For experienced developers, the course will be useful for in-depth materials on modern
standards (REST, GraphQL, gRPC), security (OAuth 2.0, JWT) and API design best practices.
Will I be able to develop APIs on my own after the course?
After the training you will have all the necessary skills: from designing endpoints and working with documentation to integrating
with external services. You will be able to both create APIs on your own and professionally evaluate the work of other developers.
How much time do I need to devote to the course per week?
On average, you will need about 8 hours per week, including watching lectures and doing practical assignments.
The course is organized in such a way that the knowledge is absorbed as efficiently as possible.
Can I combine the course with work or study?
Yes! The course is specially designed for busy people. All lectures are available in recordings, and practical assignments
can be done at your convenience. You will be able to master the material without interrupting your main activity.
How long will it take me to start earning money from API development after the course?
It all depends on your involvement. Many students start taking their first orders already during the
course - on freelancing or internships. The main thing is to put knowledge into practice right away!
What if the course doesn't work for me?
We will refund the full price if the course is not for you:
100% refund after the first 3 lessons
After the 4th lesson - prorated refund.
We will help you find an alternative training program
