Please get to the point !!!
If you are not rigorous and do not write a clean code, do not write me.
I have an external api made with j2ee that I have to consume with symfony by making the CRUD and I use the HttpClient module of symfony but as I have never done it before, I already block on the POST method. But the final system that I would like to have in place is the DTO (data transfer objects) or services to be able to consume the api. If someone has already had similar experiences. I would like to see examples of sites that you have already made. Possibility of long term collaboration.
