When you already have a V2 integrated this page will provide you with some easy steps to quickly migrate to the V3 of the Trust1Connector. Migration from the v2 to the v3 of the Trust1Connector can be done in 2 ways;
Integration of the API
Integration via the deprecated Javascript SDK
Both are viable integrations. When integrating via the API you have more control over the functionality and the dependencies used.
Update a v2 application to v3
For updating your web application first of all you need to use the new Javascript SDK. After this there are some differences in using the SDK from the v2.
Configuration
The configuration from the v2 has changed, we simplified this.
After you've created your configuration object you can do the initialisation of the Trust1Connector SDK. This has largely remained the same except for the error codes.
