OneLink API

At a glance: OneLink REST API enables creating, updating, retrieving, and deleting OneLink attribution links.

Use OneLink API to: 

  • Create, update, get, and delete OneLink URLs automatically.  
  • To generate a large number of OneLink attribution links. 
  • Customize OneLink URLs with your brand. When you generate the URL it is generated with your brand domain, instead of the OneLink subdomain.

 Example

BigTravel wants to convert its website visitors to mobile app users with personalized content. For each country web page users visit, BigTravel, using the OneLink REST API, builds a OneLink URL containing specific details for the country, user identity (if logged in) and a free admission to an attraction in that country.

OneLink API

Authentication key 

OneLink API requests must be authenticated using a OneLink API Key. 

Prerequisite:

  • The account admin needs to retrieve the API key. Team members do not have access to the API Key. 

To retrieve the OneLink API key:

  • Go to Integration > API Access, scroll down to the OneLink API section. 
  • API calls must be made over https.
  • API rate limit: The rate limit of creating OneLink attribution links via API is 250K per day, per account.
  • Requirements: Retargeting attribution data via onAppOpenAttribution is available using Appslfyer SDKs, iOS and Android, version 4.8.0 and later. 

Limitations

OneLink API has the following limitations:

  • Each OneLink attribution link created by the API has a default Time to Live (TTL) of 31 days. After 31 days this attribution link record is removed from our systems. Clicking on such an attribution Link once the TTL expires still defaults to the behavior defined in OneLink base Configuration. Maximum TTL is 31 days.
  • Any TTL value larger than 31 is overridden with the default TTL of 31.
  • TTL value can be specified in days (default), minutes or hours (e.g., 10m, 20h, 14d).
  • It is not possible to use the following special characters in the OneLink API data payload: “&”

 Note

  • Use the OneLink API only with links created by it.
  • Don't use OneLink API to update or delete shortened OneLink URLs created using the Link management page. It may break live URLs.

Onelink ID
The OneLink ID is the unique identifier for the OneLink configured in the OneLink template screen:
Shortlink ID
Given a OneLink API generated attribution link: myapp.onelink.me/ab12/qwer987 - the Shortlink ID is the last element in the attribution link structure. In the example above the Shortlink ID would be qwer987
