Step 4: Set up webhooks

Adyen sends webhooks that contain JSON objects to your Salesforce payment gateway adapter. To receive these webhooks:

In your Salesforce OMS Org, go to Setup > User Interface > Sites and Domains - Sites, and then select Site.
Select New.
Enter a label, for example Adyen.
Enter a unique value for the default web address, for example http://dev-myorganization--sandbox.cs17.force.com/adyen.
Select Active.
Select an Active Site Home Page, for example, UnderConstruction.
Select Guest Access to the Payments API.
Select Save to save your changes and make sure the site is active.
Go to Public Access Settings > Custom Metadata Type Access.
Select Edit and enable the Adyen Adapter metadata type by moving it to the Enabled column.
Select Save.
Construct the webhook endpoint URL. For this you need:
- The URL of your Salesforce site.
- The Payment Gateway Provider ID you got when creating the Payment Gateway Provider record.
For example:

In your Customer Area, go to Developers > Webhooks. If you want to configure webhooks for a merchant account, switch to that merchant account.
Select Webhook.
From the list of webhooks, next to Standard webhook, select Add.
Under General, configure the following:

Setting Description

Enabled Select the toggle to enable or disable the webhook.

Version The webhook version.

Description Your description of the webhook.
Under Server configuration, configure the following:

Setting Description

URL The webhook endpoint URL you constructed.

Method JSON

Encryption protocol The latest TLS version in the list.
Under Events, select CAPTURE, and REFUND.
Select Save configuration.

In your Customer Area, go to Developers > Webhooks.
Next to Standard webhook, select the edit webhook icon .
Select Test Configuration.
If you're on a company account, select a Merchant account from the dropdown list.
In the Event dropdown list, select the event code.

If your webhook configuration is correct, it shows a successful HTTP response status code, for example ResponseCode: 200.
