Can I reuse Google Ads OAuth across traffic sources?

When you use our Google Ads integration, you go through an OAuth flow and FunnelFlux gets a refresh token.

Provided the Google user you authenticated with has access to the Google Ads account ID in question, you can reuse that same refresh token in custom scenario settings. FunnelFlux will use that token for uploads.

The important part is Google-side access. If you change user settings or permissions in Google, such as revoking access to certain accounts, that can interfere with tracking and conversion uploads.

A refresh token you generated will also not automatically have access to newly added Google Ads accounts. If you add accounts to your Google user or MCC after generating the token, you may need to generate a new token before uploads to those accounts will work.

If you notice account access or conversion upload issues, contact support. We can check the upload logs and see what Google is returning.
