Auto-append parameters to Web destinations

Adjust supports link-level custom parameters (key-value pairs) added during link creation. When auto-appending is turned on, Adjust appends all query parameters from the long link (full click URL) to the final web destination URL.

• Reduces manual duplication of parameters across long links and web destination URLs
• Keeps web analytics consistent by ensuring the destination URL includes the same parameters as the long link
• Uses one app-level setting to control app-wide behavior
• Applies to multiple link types including partner links and custom links
• Appends all parameters or none for predictable behavior

What does it do?

When a user redirects to a web destination through adj_redirect or adj_fallback, Adjust can append all query parameters from the long link (full click URL) to the final web destination URL.

Custom parameters are included in this behavior because they are part of the long link query string.

How does it work?

Custom parameters in Adjust links

During link creation, add custom parameters as key-value pairs, for example:

• custom_param1=value1
• custom_param2=value2

Adjust adds these custom parameters to the long link (full click URL) in the format https://example.go.link?adj_t=abc123&custom_param1=value1&custom_param2=value2

Control: app-level setting

In App Settings > Defaults, enable the toggle Auto-append custom parameters to web destinations.

• Default: On
• Scope: App-level
• Applies to: Partner links, Custom links, Child links, Deep links, Combined links

When the setting is on

Adjust appends all query parameters from the long link (full click URL) to the final web destination URL.

Example destination:

https://www.example.com/path?adj_t=abc123&custom_param1=value1&custom_param2=value2

Adjust does not support selective appending. Adjust appends all parameters or appends none (except adj_t, which is always appended).

When the setting is off

Adjust appends only the link token (adj_t) to the final web destination URL.

Example destination:

https://www.example.com/path?adj_t=abc123

Other Campaign parameters and Custom parameters are not appended to the web destination URL when this setting is off.

Custom parameter rules

• Custom parameters are added to the long link (full click URL).
• Custom parameters are not appended to the short link URL itself (since short links are meant to package all the link data under the hood within the full click URL)
• URL encoding is handled during link creation.
• Parameter keys must be unique.
• Parameter names cannot include:
  • =
  • &
  • spaces

FAQ

Can I choose which parameters get appended?

No. When auto-appending is on, Adjust appends all query parameters from the long link to the web destination URL.

Are custom parameters appended to short links?

No. Custom parameters are part of the long link (full click URL). Custom parameters are not appended to the short link URL itself.
