Overview
When you're running campaigns with multiple landing pages and traffic sources, it's important to track and attribute each visit to the correct app. A key part of this is assigning the right app name to each source — whether it’s a specific landing page or the default campaign URL.
While assigning app names through landing page IDs has worked smoothly, many advertisers noticed one gap:
The default campaign URL wasn't reflecting the app name from the uploaded CSV — when a row with a blank url_id was included.
To fix this, we’ve improved the App Name Assignment feature. You can now assign app names to both individual landing pages and the default URL, all from your CSV upload. And with the addition of a Strict App Name checkbox, you get more control over how app names are applied — either flexibly or with strict matching.
Use Case
This feature is helpful for advertisers or agencies who:
Manage campaigns with multiple landing pages and default URLs
Want to assign custom app names per source using a simple CSV file
Prefer either a flexible or strict app name mapping logic
Real Scenario
A client uploads the following CSV:
url_id | app_name |
LP1 | App One |
LP2 | App Two |
(blank) | Default App |
App names for LP1 and LP2 worked correctly.
But the default URL still showed the original campaign app name, instead of "Default App".
This article explains how to prevent that — by formatting your CSV correctly and using the Strict App Name checkbox as needed.
Benefits
Assign a custom app name to the default URL by adding a row with a blank url_id in your CSV.
Accurate attribution for all sources: Each landing page and the default URL will show the correct app name in your reports.
Flexible or strict mapping control: Use the checkbox to choose between fallback behavior or exact matching.
Fewer manual errors: Automatically maps app names across complex campaigns.
Clean and consistent reports: Avoid mismatches or duplicate names caused by manual errors.
CSV Format Requirements
Your CSV file should have two columns:
Column | Description |
url_id | Landing page or source ID. Leave this blank to assign app name to default URL. |
app_name | The app name to assign to that URL ID or the default URL. |
Example CSV
url_id | app_name |
LP1 | App One |
LP2 | App Two |
(blank) | Default App |
How It Works & Where to Find the Setting
The behavior of app name assignment depends on whether the Strict App Name checkbox is enabled for the campaign.
Go to the Campaign Details Page in your panel. Scroll down to find the check the box labeled “Strict App Name” to enable strict mapping mode.
Once the checkbox is set, your uploaded CSV will be read accordingly.
When Strict App Name is Unchecked (Flexible Mode)
This mode allows for more flexibility. If an app name isn’t found for a given URL, the system assigns a random fallback name.
CSV Content | What Happens |
No url_id column | All traffic (landing + default) → random app name |
Only url_ids | Matching pages use CSV app names; others → random |
Includes blank url_id | Default URL uses app name from that blank row |
Best for: Large or dynamic campaigns where flexibility is preferred.
When Strict App Name is Checked (Strict Mode)
This mode is more controlled. Only URLs that are listed in the CSV will be assigned an app name — all others will be left blank.
CSV Content | What Happens |
No url_id column | Default URL → uses app name from blank row; others → blank |
Only url_ids | Matching pages use app names; others → blank |
Includes blank url_id | Default URL → uses app name from blank row; unmatched → blank |
Best for: Campaigns that require strict data validation and clean reporting.
Note:
If you want the default URL to have a custom app name, make sure to include a blank url_id row in your CSV.
Make sure your CSV has the correct headers and values before uploading.
