Thank you all very much for your response, I am already very glad I joined the community.
Chowderr M. Since app we’re building is actually a SaaS, and the user paying for it would trigger internal API calling to generate assets for the social posts generation(as part of one of the features we would like to add), we merely wanted confirmation from Gamma if that model of API usage is allowed within Pro plan before investing our time into it. Also auto charge is a great feature. No problem there as I was actually referring to it when mentioning small top ups as a clue.
Deeni F. Since we’re yet to incorporate API and app is in development stage there are no limitations that we face but only wondering if some would come up based on SaaS usage model in Pro plan.
Yes we like the auto recharge.
No issue with the third point, just asking in advance :)
