1. No, only customers using the old adobe analytics reporting 1.4 APIs will be affected. Also the EOL date is 12th Aug 2026. so, you have some time to migrate if you are making 1.4 API.
2. You can check the API endpoint URLs, if your integrations are calling any of the following URLs, you are using the 1.4 APIs. If they start with: api.omniture.com, api3.omniture.com, api4.omniture.com, or api5.omniture.com you are using the old APIs 1.4.
If they start with: analytics.adobe.io you are using the new APIs 2.0.
If you export the AA data using reporting API or if use third-party tools that connect to adobe analytics, contact the vendor to confirm which API version they are using. If you use 1.4 Data Sources or Classifications APIs, you must migrate to 2.0.
3. Migration means changing how your systems connect to adobe analytics, Moving from JWT or WSSE authentication to OAuth 2.0 via the developer console. This involves creating a project, obtaining credentials, and updating code to use the new authentication method.
Updating API calls to use the new 2.0 API endpoints url and adjusting to the different request/response structures. So need updating both the authentication method and the API calls.Visit to understand the migration -Migrating to the 2.0 API
As mentioned in the FAQ-
'The Adobe Analytics 1.4 EOL does not impact your tagging solutions, such as Tags (formerly Adobe Launch), WebSDK, or AppMeasurement.js. However, if you use the 1.4 Data Sources or Classifications APIs to collect or enhance your data, you must migrate those workflows to the Adobe Analytics 2.0 APIs. Please refer to the 2.0 API Endpoints guide for more details.'
