Example of how to use webhooks with payload signing is missing

[franck102]

Despite searching through the entire documentation and SDK source code I cannot figure out how to enable payload signing for webhooks with the SDK?

There is a WebhookIdentity entity that we can configure on a webhook create request, but no API to create or retrieve it? And the WebhookEncryptionService lets you retrieve a public key, but how do you create the key pair in the first place?

A complete example would be most useful...

hi @franck102 , thank you for your question but I am not sure we understand what is the problem you are running into or trying to achieve with it.

How the payload signing can be used is defined here https://github.com/wallee-payment/java-sdk?tab=readme-ov-file#integrating-webhook-payload-signing-mechanism-into-webhook-callback-handler

Hi Thibault,

The sample you mention explains how to extract and verify the signature when receiving an event. I am not receiving a signature, and the state is always null... because I haven't found how to enable signatures.

[EDIT]: I found WebhookListenerCreate.enablePayloadSignatureAndState(true) which does enable signatures & state, problem solved.

So another issue, I have two problems after using this code to create my listener:

 WebhookListenerCreate listenerCreate = new WebhookListenerCreate();
        listenerCreate.entity(entity.id).url(urlId)
            .name("passmate-" + tenantId + "-" + entity.name() + "-" + deploymentId)
            .enablePayloadSignatureAndState(true)
            .notifyEveryChange(false);

        try {
            listenerService.create(spaceId, listenerCreate);
        }
        catch (IOException e) {
            _log.error("Could not create Wallee listener for " + entity.name(), e);
        }

1. in my space UI if I check the created listener it says "Every change to Transaction entities will be reported." - so notifyEveryChange(false) apparently had no effect

2. I am receiving lots of duplicate events, with distinct IDs and timestamps - e.g. below 2 CONFIRMED, 3 PROCESSING, ...
