Payment Statuses

Session Statuses

Payment sessions can have the following statuses:

pending: Payment session created but not yet paid
paid: Payment successfully completed
failed: Payment attempt failed
cancelled: Payment session was cancelled
expired: Payment session has expired

Payment Statuses

Individual payment objects (created when processing a session) have these statuses:

processing: Payment is being processed by the payment provider
authorized: Payment has been authorized but not yet captured
succeeded: Payment completed successfully
cancelled: Authorized payment was cancelled before capture
failed: Payment processing failed

Status Flow:

Session starts as pending
When payment begins, a Payment object is created with status processing
Payment can transition to:
- authorized: Payment authorized but not captured
- succeeded: Payment completed successfully (either automatically or via Complete Payment)
- cancelled: Authorized payment was cancelled via Cancel Payment
- failed: Payment processing failed
Note: Whether payments automatically proceed from authorized to succeeded or require manual completion via Complete Payment is configured during game setup.
Session status updates based on final payment status:
- paid (if payment succeeded)
- cancelled (if session was cancelled manually via Cancel Session or after 3 cancelled payment attempts)
- failed (after 3 failed payment attempts)

Timestamp Fields

Both sessions and payments include relevant timestamp fields: Session timestamps:

created_at: When the session was created
paid_at: When the session was successfully paid (if applicable)
failed_at: When the session failed (if applicable)
expired_at: When the session expired (if applicable)
cancelled_at: When the session was cancelled (if applicable)

Payment timestamps:

created_at: When payment processing began
authorized_at: When payment was authorized (if applicable)
succeeded_at: When payment completed successfully (if applicable)
cancelled_at: When payment was cancelled (if applicable)
failed_at: When payment failed (if applicable)

Webhook Events

ToffeePay sends webhooks for the following payment-related events:

Session Events

session.created: When a payment session is created
session.paid: When a session is successfully paid
session.failed: When payment attempt related to this session fails
session.expired: When a session expires without payment
session.cancelled: When session is cancelled by user

Payment Events

payment.created: When a payment is created and processing begins
payment.authorized: When payment is authorized but not yet captured
payment.succeeded: When payment completes successfully
payment.cancelled: When an authorized payment is cancelled
payment.failed: When payment attempt fails

See the Webhooks page for implementation details and signature verification.

Open the Payment Page

Open the returned payment url in the browser or webview. The user will:

View the item details and total price
Pay using Apple Pay, Google Pay, or other supported methods
Be redirected back to your game via the return_url

Internationalization

You can customize the payment page language by adding a locale query parameter to the payment URL:

https://pay.toffeepay.com/sess_abc123?locale=es

The payment page will display all text (buttons, labels, error messages) in the specified language.

Handle Payment Notifications

ToffeePay notifies you of payment events through two methods:

Webhooks

When a payment is completed, ToffeePay sends a signed webhook to your backend. See the Webhooks page for detailed implementation. Sample Payload:

{
  "type": "payment.succeeded",
  "timestamp": "2023-06-01T12:05:00Z",
  "data": {
    // Payment object
  }
}

Return URL

After payment, the user is redirected to your specified return_url. This is typically a custom deep link that your game handles. Example:

"return_url": "mygame://payment-complete"

Frontend Events

The payment page emits events to the parent window via postMessage. This is useful for client-side integrations (e.g., if using an iframe or popup). Event Types: Payment Events (payload includes payment id):

toffeepay-payment-unreached
toffeepay-payment-success
toffeepay-payment-failed

Session Events (payload includes session id):

toffeepay-session-paid
toffeepay-session-failed
toffeepay-session-expired
toffeepay-session-cancelled
toffeepay-session-authorized

Cancel a Payment Session

You can cancel a payment session that is still in pending status:

POST /v1/sessions/sess_abc123/cancel
Authorization: Bearer <your_access_token>

Response:

{}

When a session is cancelled:

The session status changes to cancelled
The cancelled_at timestamp is set
A session.cancelled webhook event is sent
The session cannot be paid and the payment URL becomes invalid

Check Session Status

To confirm session status (especially when handling return URLs), you can use either endpoint:

Get Session (Full Details)

GET /v1/sessions/sess_abc123
Authorization: Bearer <your_access_token>

Response:

{
  "id": "sess_abc123",
  "url": "https://pay.toffeepay.com/sess_abc123",
  "status": "paid",
  "user_id": "player_42",
  "game_id": "space_shooter",
  "item": {
    "title": "50 Gold Coins",
    "price": 499,
    "currency": "USD"
  },
  "tax": {
    "amount": 50
  },
  "created_at": "2023-06-01T12:00:00Z",
  "paid_at": "2023-06-01T12:05:00Z"
}

Get Session Status (Status Only)

GET /v1/sessions/sess_abc123/status
Authorization: Bearer <your_access_token>

Response:

{
  "id": "sess_abc123",
  "status": "paid"
}

Status handling:

If status is paid, grant the items and show success
If status is pending, show a waiting screen
If status is failed, cancelled or expired, inform the user and offer to retry

Complete Payment

When your game wants to control when an authorized payment is captured, use Complete Payment. This is useful for scenarios where you want to authorize payment but only capture it after fulfilling the order (e.g., confirming item availability).

POST /v1/payments/pay_xyz789/complete
Authorization: Bearer <your_access_token>

Response:

{}

Cancel Payment

Cancel an authorized payment before it’s captured. This releases the hold on the customer’s payment method.

POST /v1/payments/pay_xyz789/cancel
Authorization: Bearer <your_access_token>

Response:

{}

Get Payment Details

Retrieve details of a payment:

GET /v1/payments/pay_xyz789?with_extra_data=true

  {
    "id": "pay_xyz789",
    "session_id": "sess_abc123",
    "status": "succeeded",
    "amount": 499,
    "currency": "USD",

    "succeeded_at": "2023-06-01T12:05:30Z",
    "extra_data": {
      "real_amount": 499
    }
  }
]

Tax Handling

ToffeePay automatically calculates and applies taxes based on the customer’s location. Tax information is included in session responses when the session is completed.

Tax Structure

The tax object in session responses contains:

amount: Tax amount in cents (same currency as the item price)

Example

For a \

4.99 item with \\

0.50 tax:

{
  "item": {
    "price": 499,
    "currency": "USD"
  },
  "tax": {
    "amount": 50
  }
}

The customer will be charged the total amount (item price + tax = $5.49 in this example). Note: Tax calculations are handled automatically during payment processing. The tax amount is determined at the time of payment based on the customer’s billing address.

Image Requirements

Item images must meet these requirements:

Format: PNG, JPG, WebP
Size: ≤ 300 KB recommended
Encoding: Base64 with MIME prefix or direct URL

Base64 format:

data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAA...

URL format:

https://yourgame.com/images/gold-coins.png

Best Practices

Authentication: See Authentication for access token management
Idempotency: Use Idempotency-Key header to prevent duplicate operations
Webhook verification: Always verify webhook signatures (see Webhooks)
Error handling: Implement proper error handling for all payment statuses
User experience: Show loading states and clear success/failure messages
Security: Use HTTPS for all webhook endpoints and return URLs
Testing: Use sandbox mode for development and testing

Error Handling

Common payment errors and how to handle them:

invalid_game_id: Check your game registration and access token (see Authentication)
invalid_currency: Ensure currency code is supported (USD, EUR, etc.)
invalid_price: Price must be a positive integer in cents
invalid_image: Check image format and size requirements
session_expired: Payment session has expired, create a new one
insufficient_funds: User’s payment method was declined

Testing

Use ToffeePay’s sandbox environment for testing:

Use sandbox access tokens (different from production)
Test with various payment methods and failure scenarios
Verify webhook delivery and signature verification
Test return URL handling in your game client

Test Codes

We don’t send real SMS messages for validating OTP in the sandbox environments. We have a static value: 466577 that can be used for getting access.

Test Cards

Use these test card numbers in sandbox mode for testing payments: Mastercard

Number: 5100 0600 0000 0002
Expiry: 12/2029
CVC: 737

Visa

Number: 4400 0000 0000 0008
