I made a simple python script to generate firebase dynamic links for my app using POST API https://firebase.google.com/docs/dynamic-links/rest
However, in web UI I can set custom link address (i.e. example.app.goo.gl/customlinkname), while using API address seems to be always auto-generated.
Is there such a feature using POST API?
I tried to set "option": CUSTOM with customSuffix parameter, however response was that option CUSTOM is not supported.
