Shopify cloaking : need help with webhook connection

Hello everyone, is anyone using payamix for shopify psp cloaking and know how to get this webhook code in order to connect the shop B ? the one I got on shopify don't work on payamix

From what I understand, the value Payamix is asking for is the webhook signing secret, not the webhook URL or API credentials. In Shopify, that secret is only available when you create or edit the webhook, so if you're trying to use an existing one, it may not be visible anymore. In that case, you usually need to generate a new webhook and use the new signing secret. If that still doesn't work, it sounds more like a Payamix integration issue than a Shopify one. I'd reach out to their support to confirm they're expecting Shopify's webhook secret and not a platform-specific token.

Maybe check the required webhook events on Payamix side, the Shopify webhook alone may not match their requirements.
