Using Google Ads API from browser - CORS

[Hugo]

Hello,

is it possible to use the Google Ads API from a JavaScript application running in the browser?

I tried making a POST request to a URL like this to fetch campaigns for a specific customer:

https://googleads.googleapis.com/v8/customers/<customer-id>/googleAds:search

But I get a CORS error "...has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource."

I know the request is correct, as I've tried it successfully using cURL/Postman.

Thanks,

Hugo

Hello,

Thanks for reaching out. This issue seems to be browser-specific. Depending on which browser you are using, you should be able to run without CORS, though this is not recommended for general use. This issue is not within out team's support scope, however. If you have any Ads API specific inquiries, we are happy to assist.
