Signature

To ensure authenticity and data integrity of incoming requests KolibriPay requires these requests to be signed. This signature is based on a Hash-based Message Authentication Code (HMAC) calculated using a request's key-value pairs and a secret key, which is known only to you and KolibriPay.

Before sending a POST, UPDATE or DELETE request to KolibriPay, you calculate a signature and add it as a request parameter. When a request comes in, KolibriPay calculates the same signature based on the received key-value pairs and the secret key stored by KolibriPay. By verifying that both signatures are equal, KolibriPay ensures that the request is not tampered.

Similarly, you can validate responses from KolibriPay by calculating the corresponding signature and comparing it with the signature in the response. This allows you to verify that the events were sent by Kolibri and not by a third party.

Preventing replay attacks

A replay attack is when an attacker intercepts a valid payload and its signature, then re-transmits them. To mitigate such attacks, KolibriPay includes a timestamp in the response body. Because this timestamp is part of the signed payload, it is also verified by the signature, so an attacker cannot change the timestamp without invalidating the signature. If the signature is valid but the timestamp is too old, you can have your application reject the payload. We suggest a 5 minutes tolerance between the timestamp and the current time.

Calculate & Verify Signature

Each signed response includes a kolibripay-signature header. This header contains a signature. You should always compare the signature in the header to the expected signature.

Below are some examples that illustrate how to determine the expected signature.

All the examples output the following signature: qnR8UCqJggD55PohusaBNviGoOJ67HC6Btry4qXLVZc=\nThis signature is the result given the values of secret and Message. Take notice of the capital M.

To verify KolibriPay signature, replace secret with your secret key and replace Message with the raw request or response body.

Test Mode

Before processing live payments, we recommend testing your integration first by using the test mode. To enable the test mode simply include a header called test-mode with it's value set to true instead of the kolibripay-signature header.

The following endpoints support the test mode:

Update Transaction
Delete Transaction

Webhook

KolibriPay can send webhook notification events to your server to notify you when the status of a transaction changes. This is useful for purposes like determining when to fulfill the goods and services purchased by your customer.

To handle a webhook notification event, you will have to expose an endpoint on your server and configure a corresponding webhook endpoint in the KolibriPay dashboard.\nThis endpoint on your server has to be able to receive HTTP POST requests.\nNotification events are signed by KolibriPay. The signature can be found in each event’s kolibripay-signature header

The following example shows a notification payload containing the transaction status :

{\n    \"accountNr\": \"20003000\",\n    \"amount\": 1000,\n    \"amountPaid\": 1000,\n    \"currency\": \"ang\",\n    \"id\": \"eG2be22kWOXwubHRRmLZ\",\n    \"status\": \"success\",\n    \"timestamp\": 1597669104352\n}
