<br>PhonePe Charge APIs are used primarily for offline organized merchants. PhonePe APIs are integrated with the merchant Billing POS. A merchant can request a payment from a customer by sending a collect request to the user's PhonePe app.
A merchant does Offline Integration primarily for:
<b>Accepting Payment at Offline Stores</b>: The merchant sends collect request at the time of checkout.
<b>Offline Delivery</b>: The merchant sends the collect request at the time of checkout. The customer receives a notification on their PhonePe app and completes the payment once the good/service is delivered.
