Where do I find field length limits for the Google AdWords API?

Question

I am having to use the Google AdWords API for a project, I have large chunks working but I am getting frustrated with the documentation. For example I know that a TextAd headline field has a limit of 25 characters and can't have things like ! and ? in it. The documentation makes no mention of it though: http://code.google.com/apis/adwords/docs/reference/v200909/AdGroupAdService.TextAd.html

Does anyone know where I can find this kind of info? This is not a question about the TextAd service, but about the documentation so that I don't have to find the limits of all these fields by trial and error.

Many thanks, b.

You won't find these limits in the AdWords API documentation anywhere, because these limitations are imposed by AdWords policies rather than any sort of character limit in the API.

Therefore, you must resort to AdWords documentation in order to find out things like the maximum length for an ad description or headline.
