In some cases (for some status code), the webhook returns different status code as which was set.

I created simple integration Webhook->InvokeSQL for every return code.
For return 2xx codes, I used `INSERT INTO todo (task) VALUES ('test')` query in the invoke SQL step.
For 4xx and 5xx codes, I used `INSERT INTO contact (create_date) VALUES ('Red Hat')` query in the invoke SQL step.

After that, I published all integrations and invoked the webhooks.

202	204
204	204
400	200
