Hi Julien, If you get the same numbers in the UI than you can ask product support how simulations work. The API only gives access to what the UI offers.
With that being said, in product support guide Estimate your results with bid, budget and target simulators I noticed "Because campaign-level bid changes can increase traffic significantly, we'll tell you whether you need to increase your budget and, if so, what to change it to." It makes sense that the simulators aren't bound by budget, they can suggest a budget. If your real world results were lower it could be because your budget was lower. If you find a discrepancy from what appears in the UI, could you privately send us a screenshot of the UI along with an Ads API request and response log of communications that doesn't match the UI? The request and response appears similar to the JSON Mappings in our REST documentation. Our client libraries have loggers with logging instructions, to see these instructions you can click on the client library you use in the sidebar of our client library guide and click on "Logging". When the correct logger is set to 'DEBUG' then the correct logs are generated.
