Syncing Your Meta Assets — How It Works

Last updated: April 18, 2026

Wevion keeps your Meta assets (ad accounts, fan pages, pixels, and catalogs) in sync with your Meta Business Manager. This article explains how the sync process works and what happens behind the scenes.

Prerequisites

A connected Meta account Connecting Your Meta (Facebook) Account
At least one Meta Business Manager with assets

How It Works

When you connect your Meta account to Wevion, the platform automatically discovers and syncs all your Meta assets. This sync process runs:

On first connection — All assets are discovered and imported
On demand — When you click the Sync button on any asset page
Periodically — Background jobs keep your data fresh

The sync process is non-destructive — it adds new assets and updates existing ones but never deletes assets that still exist on Meta.

What Gets Synced

Ad Accounts

Wevion discovers ad accounts from three sources:

	SourceDescription
Owned Accounts	Ad accounts directly owned by your Business Manager
Client Accounts	Ad accounts shared with your Business Manager by other businesses
Employee Assigned	Ad accounts assigned to you as a business employee

For each ad account, Wevion stores:

Account ID and name
Currency and timezone
Ownership type (owned vs client)
Available tokens for API access

Fan Pages

Same three-source discovery:

Owned pages from your Business Manager
Client pages shared with your BM
Employee-assigned pages

Pixels

Pixels are discovered at two levels:

Business Manager level — Owned and client pixels
Ad Account level — Pixels connected to each of your ad accounts (catches shared pixels from other BMs)

This two-level approach ensures no pixels are missed, even those shared across businesses.

Catalogs

Catalogs are discovered from:

Owned product catalogs
Client product catalogs
Assigned catalogs (for system users with catalog management permissions)

The Sync Process — Step by Step

1. Trigger

You click Sync on any asset page (Ad Accounts, Fan Pages, Pixels, Catalogs), or the system triggers an automatic sync.

2. Background Processing

The sync job is dispatched to a background queue. This means:

You can continue using Wevion while the sync runs
The sync processes all your Business Managers and tokens in parallel
A notification tells you when the sync is complete

3. Discovery

For each of your Meta tokens and Business Managers, Wevion calls Meta's API to fetch all available assets. It paginates through results to ensure nothing is missed.

4. Upsert

For each discovered asset:

New assets are created in Wevion's database
Existing assets are updated with the latest information (name, currency, timezone)
Token access is merged — if multiple tokens can access the same asset, all are recorded

5. Cleanup

After a fully successful sync (all tokens and BMs processed without errors), assets that no longer exist on Meta are cleaned up. If any part of the sync failed, cleanup is skipped to prevent data loss.

6. Notification

An in-app notification confirms the sync result: how many assets were found, updated, or added.

Resilience and Error Handling

The sync system is designed to handle failures gracefully:

	FeatureHow It Works
Retry with backoff	If a Meta API call fails, it retries up to 3 times with increasing delays
Circuit breaker	If too many consecutive calls fail (5+), the system pauses requests for 60 seconds before trying again
Token rotation	If one token fails, Wevion tries the next available token
Partial success	A failure syncing one Business Manager doesn't block others from syncing
Safe cleanup	Asset cleanup only runs when ALL sync tasks succeed

Step-by-Step: Manually Triggering a Sync

Navigate to any Assets page (Ad Accounts, Fan Pages, Pixels, or Catalogs)
Click the Sync button in the toolbar
A loading indicator appears while the sync runs
When complete, the table refreshes with the latest data
Any new assets appear in the list

Frequently Asked Questions

Q: How long does a sync take? A: For most accounts, sync completes in 10-30 seconds. Large Business Managers with hundreds of assets may take up to a minute.

Q: Why don't I see an ad account I have access to in Meta? A: Possible reasons:

The token you connected doesn't have access to that Business Manager
Your role in the BM may not grant access to that specific account
Try reconnecting your Meta account to refresh token permissions
If using an Employee role, you can only see accounts explicitly assigned to you

Q: Does syncing affect my running campaigns? A: No. Syncing only reads data from Meta — it never modifies campaigns, budgets, or any active entities.

Q: What if I disconnect an ad account from my BM in Meta? A: On the next sync, the account will be cleaned up from Wevion (only if the sync completes without errors). Historical data for that account is preserved.

Q: Can I sync just one specific asset? A: The sync processes all assets of that type at once. You can't sync a single ad account — the entire ad account sync runs, which is fast and ensures consistency.

Q: What's the difference between "syncing" and "assigning"? A: Syncing discovers which assets exist in your Meta BMs and imports them into Wevion. Assigning grants Wevion's tokens permission to manage specific assets (like ad accounts). After syncing, you still need to assign (connect) assets before they can be used for campaign management.
