API Documentation Templates on RoboHelp

Your options are going to vary depending on what version of RH you have. 

If you click File > New  > Project in RH 2019 Classic or older, you'll see a list of templates available. I don't believe any are specific to an API, but perhaps one is close enough you could adapt to your needs.

I can't remember the path or options for RH 2019 New. I feel like there are fewer options, but I don't have access right now.

First of all I see all forum posts so if you post there I reply where I have an answer. Private messages are for things that cannot be discussed openly for whatever reason, not for grabbing someone's attention.

Am expecting your reply on this to plan my works this weekend. Please consider this as an immediate favor.

All forum supporters will answer as quickly as their other commitments permit. If that is not quick enough, then you need to contact support.

I am happy to help people on the forum but you are better off posting on the main forums, as you did, as there you will get answers I cannot cover or am simply not available to assist with.

Good luck with what you need to do.

API template in RH? Nope.
