Which field contains the Authorization Id to capture the payment in the capture call?

[amitsingh]

Hello Experts,

I am working on Salesforce-Paypal integration and I am able to create the authorization and approve the payment using both v1 & v2 API. Now I am having the problem in finding which response field contains the Id for authorization which needs to be sent in the next API call to capture the payment.

Thanks in Advance
