Payment Webhooks
Get transaction information with webhooks
Merchants has the possibility to subscribe to different events that affect a payment and to be notified directly when these events happen. When an event occurs in Easy; for example, a charge is made or a payment is refunded, this event can be sent along with the associated data directly to the merchant.
Configuring webhooks for a payment
Easy will send the event as a HTTP POST request to the URL specified by the merchant.
Webhooks are configured per payment and are specified in the create payment request.
When you subscribe to a webhook, Easy will try to send the request to the specified URL until the server responds with a 200 OK status code. If the server responds with anything else, or times out, a certain number of retries are made with increasing time between each attempt. Supported events for webhooks:
To register a webhook, use the following format:
"notifications": {
"webhooks": [{
"eventName": "payment.created",
"url": "string",
"authorization": "authorizationKey"
}]
}
The authorization field is used by Easy to set the authorization header of the http request when sending the webhook to the merchant site. This header should be verified by you to ensure that the request has come from the correct source.
Receive a webhook
It is very easy to receive a webhook. Just set up a new endpoint on the preferred site and read the JSON body of the request to get the event data.
C# code example:
public async Task<ihttpactionresult> Post()
{
var content = await Request.Content.ReadAsStringAsync();
dynamic eventData = JsonConvert.DeserializeObject(content);
return Ok();
}
Note that the webhooks need to be sent over HTTPS when designing the endpoint.
Webhook content
The webhook content will have the following format:
{
"id" : "f3d5043af4094d6887ee95bf16073958",
"merchantId" : "e718004345cc48cba095a235de85c359",
"timestamp" : "2018-01-12T09:40:19.8919+00:00",
"event" : "payment.refund.completed",
"data" : {
...
...
}
}
The data property inside will contain the event data for the specified event and will change accordingly.
See separate list for details on each event.
Responding to a webhook
To acknowledge the webhook sent from Easy, a 200 HTTP status code is required. Any other status code, even other 2XX codes, will be treated as a not successful attempt.
If the webhook was not successfully posted to you, Easy will continue to send the webhook with an increasing interval in time between each attempt. If your site still has not responded with 200 after this period, the webhook will not be attempted any more.
