With Zapier, improvements are required in the areas of concerns like bugs, ease of use, and documentation. The product has many bugs, so users have to wait for a period ranging from five minutes to an hour to see where the Zap went. In Zapier, Zaps aren't very understandable owing to the way they work. As a user, you would think that in Zapier, a Zap works in a particular way once you set it up, but it won't happen. At times, some Zaps can interfere with each other, because of which there might be infinite loops that may occur, owing to which multiple Zaps continue to run or break down in general, after which nothing would run in your environment. You would not be notified about the breakdown of Zaps. The bugs in the product may be considered to understand or get an explanation of how Zaps works between software systems, so for something between Gmail and HubSpot, Zapier would explain through better documentation what would work and what wouldn't work. Maybe if Zapier had better functionality with Python or any other coding language in general, it would make the product a lot better.
