How quickly will my ads be approved and/or shown when using the API

[Gabriel]

Hello.

I have to modify the text of my ads in a daily basis because of the inflation crisis existing in my country.

Since I have tens of campaigns and products to promote I am going to use the Google Ads API.

The text of the ads will be always the same, except for the pricing.

Let say:

Looking for Tennis Balls ? get 3 for $x

changing X dialy.

my questions are:

a) what is the correct ad type to use ?

b) may i use regular, most simple ads ?

c) when changing a text of an Ad via Google Ads Website, the ad is sent to approval again, loosing valuable time.

what happends via API ?

d) is it better to modify an Ad or to delete it and publish a new one ?

e) what happends with sitelinks ?

thank you,

gabriel
