I have several ad accounts, one per Instagram profile. Which one do I choose?

Choose the ad account that manages the ads for the event you want to analyze in Nevent, not the Instagram profile itself.

When I open Ads Manager, Instagram asks me to log in with my personal account. What does that mean?

That happens when you go directly into Meta Ads Manager from your browser, and it's not part of the connection process with Nevent. Meta asks you to identify yourself with your personal account because access to a business's advertising goes through your individual profile inside the Business Manager.

I authorized Meta but Nevent still doesn't show it as connected. What should I check?

Check three things: that your user has the admin or advertiser role on that ad account inside the Business Manager, that you selected the correct account during authorization and not another one in your Business Manager, and finally go back to Settings → Paid Ads and click Connect again to repeat the authorization.

How to connect your Meta, Google and TikTok accounts

Connecting your Meta, Google and TikTok accounts is the first thing you need to do so the Paid Media module in Nevent can show the spend and performance of your ads in a single panel. The process is a standard authorization (OAuth): you approve access from your own account, without installing anything.

In this guide you connect all three platforms. Each one has its own card and its own button, so you can connect them all in a row or just the one you use. Count on about 10 minutes if you’re connecting all three, or about 3 minutes for each one if you connect them separately.

Before you start

You need enough permissions on each platform to authorize access. Check them before you start:

Meta (Facebook and Instagram Ads): you need the admin or advertiser role on the ad account inside your Business Manager. Source: Meta Business Help Center, “What are the ad account permission roles in Meta Ads Manager?”.
Google Ads: you need Standard or Admin access level on the Google Ads account. Read-only access does not let you complete the authorization. Source: Google Ads Help, “About access levels in your Google Ads account”.
TikTok Ads: you need a role that lets you manage ads in the TikTok Business Center.

If you don’t have any of these permissions, ask whoever manages that account at your company before continuing.

Step 1: go to Settings → Paid Ads

In the side menu of Nevent, go to Settings and click Paid Ads.

You’ll see a card for each platform: Meta Ads, TikTok Ads and Google Ads. Each card is independent, with its own button and its own status: Not connected with a Connect button, Connected with the account name, or Error with a Retry button.

Step 2: connect your Meta account

Click Connect on the Meta Ads card. Nevent takes you to Meta’s authorization screen, where you sign in with your personal Facebook account and choose the Business Manager and the ad account you want to share with Nevent.

After accepting, you go back to Settings → Paid Ads and the Meta Ads card now shows the Connected status.

Step 3: connect your Google Ads account

In Settings → Paid Ads, click Connect on the Google Ads card.

Step 4: connect your TikTok Ads account

In Settings → Paid Ads, click Connect on the TikTok Ads card. Sign in with your TikTok Business Center account and authorize access to the ad account you want to analyze in Nevent.

What to check

Each platform’s card should show the Connected status, with the ad account name and the date of the last sync.
If you have several ad accounts, one per profile or brand, confirm that the one showing as connected is the one that manages the event you want to analyze.
If Meta doesn’t show as connected after authorizing, check your role in the Business Manager, confirm you selected the correct ad account during authorization, and click Connect again to repeat the process.
To see the detail of your campaigns once connected, follow how to read a campaign, ad set and ad detail.
