In SendGrid, open Settings → API Keys and create a key with required access. For a signed Event Webhook, enable signature verification and retrieve its public verification key.
Configure in nodulz
In your instance, open Credentials, select the type above, name the credential and complete these fields:
text
apiKey, baseUrl, sendgridVerificationPublicKey
Save the credential, then select it on relevant nodes. URLs or parameters marked as node settings belong directly on that node.
Things to check
Sending needs Mail Send permission and a verified sender. The webhook public key does not replace the API key used for REST calls.
Verify an operation with expected permissions and data before publishing. Keep secrets out of logs and revoke them with the provider when no longer needed.
