Adding "Yes" in the captureOnly action code is to be used as a separate transaction after Authorization Only payment transaction is processed and successful.

"captureOnly":"yes" 📷 will update a previous Authorization for Capture. Transaction usually follows an Authorization Only transaction within a few hours or days. An authorization usually “falls off” a consumer’s card in about a week making the funds available to the consumer again and thus increasing the “open to buy” amount on the card.
