I'm new to the site but think I have the basics of manually updated goals figured out. I've set up a beeminder goal to record the NET amount of tasks completed on my to-do list, i.e. [Number of tasks completed today] minus [Number of new tasks added to the list] = X. The idea is that as long as X is a positive number over time, my to-do list is growing shorter and not un-manageably longer. Right now this is a manually calculated and recorded goal, and I could see it being easy to get sick of all the calculation over time and stopping.
Is there a way to calculate the Net tasks completed number directly from Todoist through Zapier? I don't currently use Todoist as my to-do list, but I'd be willing to try using it if I could automate this piece. I know there is a Zap for total tasks completed in Todoist, but I don't know what other trigger fields are available.
Any help would be greatly appreciated.
