PayPal - Capture Authorization

See more PayPal Examples

Capture and process a previously created authorization. The original payment call must have the intent set to authorize.

Note: This example requires Chilkat v9.5.0.65 or greater.

Rust

// Note: Requires Chilkat v9.5.0.64 or greater.

// This requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// Load our previously obtained access token. (see PayPal OAuth2 Access Token)
let json_token = chilkat::JsonObject::new();
let _ = json_token.load_file("qa_data/tokens/paypal.json");

// Build the Authorization request header field value.
let sb_auth = chilkat::StringBuilder::new();
// token_type should be "Bearer"
let _ = sb_auth.append(&json_token.string_of("token_type").unwrap_or_default());
let _ = sb_auth.append(" ");
let _ = sb_auth.append(&json_token.string_of("access_token").unwrap_or_default());

// Make the initial connection.
// A single REST object, once connected, can be used for many PayPal REST API calls.
// The auto-reconnect indicates that if the already-established HTTPS connection is closed,
// then it will be automatically re-established as needed.
let rest = chilkat::Rest::new();
let b_auto_reconnect = true;
if rest.connect("api.sandbox.paypal.com", 443, true, b_auto_reconnect).is_err() {

    return;
}

// ----------------------------------------------------------------------------------------------
// The code above this comment could be placed inside a function/subroutine within the application
// because the connection does not need to be made for every request.  Once the connection is made
// the app may send many requests..

// To capture a particular amount, build JSON such as this:
let json = chilkat::JsonObject::new();
json.set_emit_compact(false);
let _ = json.update_string("amount.currency", "USD");
let _ = json.update_string("amount.total", "6.70");
// is_final_capture is optional and indicates whether to release all remaining funds that the authorization holds in the funding instrument.
let _ = json.update_bool("is_final_capture", true);
println!("{}", json.emit().unwrap_or_default());

// The JSON created by the above code:

// 	{ 
// 	  "amount": { 
// 	    "currency": "USD",
// 	    "total": "6.70"
// 	  },
// 	  "is_final_capture": true
// 	}

// This is the OAuth2 Authorization header, not to be confused with a PayPal credit card authorization...
let _ = rest.add_header("Authorization", &sb_auth.get_as_string().unwrap_or_default());
let _ = rest.add_header("Content-Type", "application/json");

// The authorization ID is added to the path.
// The authorization ID is obtained from payment records as shown here: Find Authorizations
let sb_path = chilkat::StringBuilder::new();
let _ = sb_path.append("/v1/payments/authorization/authorization_id/capture");
let num_replaced = sb_path.replace("authorization_id", "6HG91590AX913463C");

let sb_json_request = chilkat::StringBuilder::new();

let sb_json_response = chilkat::StringBuilder::new();
