Yes it is possible through grapghql admin api. I implemented this in php. That working fine
Hi all - just to add a little context, especially if anyone joins this thread later. You would want to start with our documentation on price lists and product catalogs here. Lots of information on international pricing and how to implement it using the Markets component of the GraphQL admin API like @Kumar2573 mentioned. Hope this helps!
