I have created a webhook type in in zoom and trying to validate the endpoint as shown in the document below. But I am not able to get the verification done.
The URL that I am trying to validate : https://nextgen--agilebrain.sandbox.my.salesforce-sites.com/zoomRecordings/services/apexrest/sampleWebh
Hashing code :
String signature = EncodingUtil.base64Encode(Crypto.generateMac(‘HmacSHA256’, Blob.valueOf(plaintoken), Blob.valueOf(csecret)));
Reference documentation: https://marketplace.zoom.us/docs/api-reference/webhook-reference/#validate-your-webhook-endpoint
How To Reproduce
Click the validate button from the webhook only app.
