API V3 Documentation
An overview of the W2 Global Data API V3
API Version 3
The API exposes two methods: KYCCheck and DocumentUpload.
This is the most common method for calling the API. The call to the KYCCheck method takes a bundle name and a set of query data as parameters and goes through each service in that bundle. It will return a response from each service that is called along with an interpret result.
Some services perform document verification by looking at images of important documents (passports and driving licenses etc.) and as such we need to upload a document to W2. This method is used to upload documents.
