A question about the rounding method used in AdWords API for bids and their modifiers

[Mikalai Kuzmitski]

Hello, I need  fully understand the process of calculating the final maximum CPC bid by setting the basic CPC bid ("microAmount") and device modifiers ("bidModifier") through the AdWords API.
Could you clarify:
1) what kind of rounding method do you use?
2) whether the rounding is applied to the basic CPC bid and modifiers separately, or is only the final CPC bid being rounded, so:
final CPC bid = rounded(basic CPC bid * modifier) or final CPC bid = rounded(rounded(basic CPC bid) * rounded(modifier))
3) Could you, please, use the examples below explain what the basic CPC bid, modifiers and final CPC bid will be applied and received through the corresponding Ad reports, if I try:
 - basic CPC bid = 2.985, modifier = 0.875,
   will be used: basic CPC bid = ? modifier= ? final CPC bid = ?
- basic CPC bid = 2.98556, modifier = 0.87556,
   will be used: basic CPC bid = ? modifier= ? final CPC bid = ?
- basic CPC bid = 2.98501, modifier = 0.87501,

   will be used: basic CPC bid = ? modifier= ? final CPC bid = ?

Hi Mikalai,

Thank you for reaching out to our API support team.

Regarding the rounding off behavior, and since this is more of a Product related concern, then I would recommend that you reach out instead to the Google Ads Product Support team, via this link, for further guidance. I hope this helps.

Hi, 

Thanks for the answer.

Surprisingly, they recommended contacting your forum).

Maybe you could still clarify, although some of the questions?

I see a similar discussion on the forum (https://groups.google.com/g/adwords-api/c/lmAZt7bjJ1w/m/YpiXyA2jAwAJ),

but I'm interested in exactly the calculations on the API side, and not on the UI + I'm also interested in modifiers.

Best regards, Mikalai

Hi Mikalai,

A bid must be a whole multiple of 0.010000 when using the AdWords API or the UI, I just tried both ways. Could you send me a request and response log of communication with the API log that shows otherwise?

A request looks like the 3rd section in request and a response looks similar to response. Logging instructions are in the read.me on Github of each client library.

When setting the logger to 'DEBUG' you can see the requested logs.
