Process payment result

After the customer completes the payment process, the AppotaPay system notifies the result to the partner's system through 2 forms

note

• It is necessary to thoroughly check the parameters status, orderAmount, and signature to ensure they are valid before confirming the transaction as successful
• It is recommended to call the api to check the transaction status to ensure the most accurate updated results
• Use the 'signature' parameter to verify the integrity of the received data. The partner generates a signature from the data received from AppotaPay, then compares it with the 'signature' parameter sent by AppotaPay

Redirect URL

• Customers will be directed to the partner's URL passed through the API via the 'redirectUrl' parameter.
• On this page, the partner checks the data, transaction status, and displays notifications to the customer.

The parameters (query string) sent along with the URL

Method: GET

Params	Data type	Description
data	String	The transaction information is in base64encode & json_encode format.
signature	String	Signature to verify data integrity signature = HMAC_SHA256(data, secretKey)
time	String	Response time

IPN (Instant Payment Notification)

AppotaPay will send transaction notifications via the partner's API URL submitted to the API through the 'notifyUrl' parameter. The partner's server verifies the integrity of the data via the 'signature' parameter and then updates the status of the order

Header

{
    "Content-Type": "applicaton/json"
}

Response params

Method: POST

Params	Data type	Description
data	String	The transaction information is in base64encode & json_encode format

In both IPN & URL, when notifying the Partner, the data format will be the same.

Response format

• When confirming a successful transaction via IPN, the partner needs to respond to AppotaPay to confirm that they have received the result
• In case the partner does not respond successfully, AppotaPay will attempt to respond up to 3 times, with a 5-minute interval between each attempt.
• The response is considered successful when HTTP code = 200 and the status parameter in the response body = 'ok'.

Example success response

HTTP Code: 200

Body: {"status": "ok"}
