Document Verification (Crop) Api via Postman or C#
Postman Example
This describes the process of calling the Document Verification Crop endpoint using Postman
Postman is a free app that allows you to perform HTTP requests. You can download it from the Postman website here.
Option 1 – Download and import our example collection
We have set up an example Postman collection that contains example requests that you can import https://github.com/W2-Global-Data/Api-Samples/tree/main/REST
All you will need to do is insert your W2 provided API key into the Authorization header of any request in the collection and it should work
Option 2 – Setup your own
1) Set the request method to Post
2) Set the URL to the verify endpoint: https://api.w2globaldata.com/document-verification/crop?api-version=1.1
3) Add an Authentication header to the request with the schema Basic and the value set to your Api Key.
4) Set the body of the request to ‘form-data’
5) Add the request values to the body. Full request details here
6) Send the request and view the response.
