Setting Your Webhooks
Also in your api dashboard, you will see a section titled "Webhooks" Here you can define all your different webhooks
Receive webhooks will get triggered when a user replies to one of your messages. This webhook structure can be found in the Receiving Documentation
To increase security of your application, Sendblue offers users the ability to define a webhook secret in their dashboard. This way, a server can verify that every request they get is coming from Sendblue, rather than an unauthorized third-party.
How it works
Once you define a secret in your dashboard, all future inbound message webhook requests will contain a header called
sb-signing-secret. Check this against the secret you've defined before performing any sensitive actions.
Webhook secrets are entirely optional, but highly recommended.
