Contact Form 7 If Condition

Yes, you should be able access the form fields and field values with event.detail.inputs in addEventListener on wpcf7mailsent. You can then use the field values in the conditional statements and add the redirects you need. There’s a simple code sample in the plugin doumentation, https://contactform7.com/dom-events/, for looping the fields.

EDIT
Here’s a code example,

document.addEventListener( 'wpcf7mailsent', function( event ) {

  var inputs = event.detail.inputs,
      inputCount = inputs.length,
      firstCondition,
      secondCondition;

  for ( var i = 0; i < inputCount; i++ ) {
    if ( 'first-condition-field' == inputs[i].name ) {
      firstCondition = inputs[i].value
    } else if ( 'second-condition-field' == inputs[i].name ) {
      secondCondition = inputs[i].value
    }
  }

  if ( 'foo' == firstCondition && 'bar' == secondCondition ) {
    location = 'https://www.example.com/thank-you-1/';
  } else if ( 'bar' == firstCondition && 'baz' == secondCondition ) {
    location = 'https://www.example.com/thank-you-2/';
  }

}, false );
