Reference documentation for webhooks
Webhooks are designed for customers to manage their subscriptions and receive notifications about events. Events are triggered by the system to signal a change has occurred after a certain action is performed. By receiving notifications customers are able to react accordingly.
For example, customer can provide an endpoint in order to receive notification on direct bank transfer creation. Then instead of having to poll whether creation succeeded or not, it will be notified when direct bank data transfer successfully completes or fails.
The following list contains the event and primary ID field names as used when subscribing to webhooks and in the webhooks message, and short descriptions of the events. Currently, webhooks are mostly used for endpoints which require 2-factor authentication.
The search functionality can be utilized to search by category, event, primary ID, or description.
Category | Event | Primary ID | Description |
---|
Please read Webhooks section in complete API reference for more details.
Example of payload for push notification:
{
"eventType": "string",
"webhookUuid": "string",
"payload": "object",
"meta": {
"version": "string",
"timestamp": "long",
}
}
Let's say request for invoice payment was created for invoice with ID = 1 and transaction identifier = 123456789 was assigned. Then the transaction was confirmed, and now we would like to know if payment was created successfully or not.
To receive push notification via Webhook, user needs to first subscribe to the event it's interested in. Suppose user has already subscribed to INVOICE_PAYMENT_CREATED event by calling POST /webhooks with the following request body:
{
"url": "www.customerurl.com/myinvoicepaymentcreated",
"authenticationType": "HMAC"
"authenticationMeta": {
"sharedSecret": "1234567890",
"hashFunction": "SHA512"
}
"subscriptions": [
"INVOICE_PAYMENT_CREATED"
]
}
And API has sent a successful response with webhook uuid 0example-uuid-0000-0000-000000000000.
Result is sent to the provided URL for the registered event.
{
"eventType": "INVOICE_PAYMENT_CREATED",
"webhookUuid": "0example-uuid-0000-0000-000000000000",
"payload": {
"transactionIdentifier": "123456789",
"transactions": [
{
"paymentId": 123, // Identifier of created payment, provided by the application
"invoiceId": 1
}
]
},
"meta": {
"version": "latest"
"timestamp": "1672542755"
}
}
Note that payload in this case contains transaction identifier and body of the invoice payment response. Please check InvoicePaymentSummaries schema in complete API reference
Result is sent to the provided URL for the registered event.
{
"eventType": "INVOICE_PAYMENT_CREATED",
"webhookUuid": "0example-uuid-0000-0000-000000000000",
"payload": {
"transactionIdentifier": "123456789",
"errors": [
{
"status": 400,
"field": "payerBankAccount",
"message": "INVALID_PAYER_BANK_ACCOUNT"
}
]
},
"meta": {
"version": "latest"
"timestamp": "1672542755"
}
}
Instead of using Webhook, user calls PUT /payments/123456789/confirm
{
"transactions": [
{
"paymentId": 123,
"invoiceId": 1
}
]
}
{
"errors": [
{
"status": 400,
"field": "payerBankAccount",
"message": "INVALID_PAYER_BANK_ACCOUNT"
}
]
}
