Introduction

The OneLink REST API provides programmatic access to read and write shortened OneLink attribution links. The OneLink API not only allows for useful link shortening, but also enables creating and shortening thousands of OneLink URLs automatically. OneLink REST API is an AppsFlyer premium feature. Please contact your CSM or send at a request to hello@appsflyer.com

Using the OneLink API you can create thousands of OneLink attribution links per day. You can also update, delete or query them once created.

 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.

Authenticating OneLink API Requests 

To prevent misuse, applications must authenticate all API requests using their OneLink API Key. Authenticate the API calls using the OneLink API Key exposed in the API Access screen in the AppsFlyer platform, under the OneLink API key section.

Note that all API calls must be made over https.

API rate limit

The rate limit of creating OneLink attribution links via API is 50K per day, per account.

Requirements

  • Retargeting attribution data via onAppOpenAttribution is available only from iOS and Android SDK version 4.8.0.

Known limitations

The 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: “&”

 Warning

Use the OneLink API ONLY with links created by it!
Do not use the OneLink API to update or delete shortened OneLink URLs created with the Link management page, as it may break these live URLs.

Glossary

Onelink ID
The OneLink ID is the unique identifier for the OneLink configured in the OneLink configuration 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
