I am looking to add ads to my Xcode project using google ads. I already downloaded cocoapods successfully and was able to connect it to my Xcode project but then I ran into an error while trying to download the pod required to get ads.

### Error

here is the error message I get while trying to use the command install pod --repo-update. I updated cococapods already and still had this problem. I am using an M1 MacBook Pro for this. Do you know how to solve this?

I have a mobile game, in which i have user engagement of 10 minutes and user retention day 1 of 27%, I'm doing app promotion on Google Ads, so in USA and United Kingdom my CPI in Google Ads is 0,15$, But i still have ROI = 0,4, is that not too small?

Can anyone help me on some suggestions on what makes that so small? Thanks in advance.

I have created a test account in https://console.cloud.google.com/

I followed the instructions in the following link: OAuth Web Application Flow

All went ok till Step 3 - Generating a refresh token. In Step 3: sub steps 1-4 went ok as describe in the link.

But on sub step 5 I am getting :

The authentication flow has completed. You may close this window.

and in my cmd I see:

Access token: XXXXXXXXXX Refresh token: None

Can someone please help me to understand what am I doing wrong?

Thanks,

Nir

I've set up the whole Google Ads API according to this manual here: https://developers.google.com/google-ads/api/docs/client-libs/python/oauth-desktop?hl=en

I got my refresh token and put it in my google-ads.yaml file which looks exactly like this: https://github.com/googleads/google-ads-python/blob/master/google-ads.yaml. I also put my client_id, developer_token and client_secret at the corresponding spots in the file.

Everything worked out and I could for example ask for all campaigns: https://developers.google.com/google-ads/api/docs/samples/get-campaigns#python. Also I could use other services of the API.

Each time I use the API I access it via the client using the following code:

from google.ads.google_ads.client import GoogleAdsClient client = GoogleAdsClient.load_from_storage(path_to_google_ads_yaml_file) 

As I already said it worked.

A few days later I tried to connect again and I got the following error:

 “error”: “invalid_grant”, “error_description”: “Token has been expired or revoked.” 

So I did the process of getting a new refresh token again (https://developers.google.com/google-ads/api/docs/client-libs/python/oauth-desktop?hl=en) such that everything worked out again.

One day later I got the same error again. So my question is: What is the purpose of the refresh token? I thought it allows me to access the API without ever having to ask for a new token or refresh token!?

Now, I again tried to connect to the API once more (although it didn't work last time) and now I got an even worse and new error:

'invalid_grant: Bad Request', '{\n  "error": "invalid_grant",\n  "error_description": "Bad Request"\n}' 

So things are getting even more complicated...

I’m trying to forecast the value of various keywords using the google Adwords API, using the traffic estimator service. So far, the clicks, costs per click, and other metrics returned through the API don’t come anywhere close to those retrieved through the Keyword Planner console. There are several adjustable forecast parameters in the console such as language, location, and search network, and I tried to match these parameters in the API.

I'm wondering if there is some other element that needs to be adjusted that I'm missing. For example, the console gives you the option to "select an ad group" for the forecast, and I'm not sure how this would be applied within the API.
