Introduction

PostShiba is the email API Bento runs on.

PostShiba is the transactional email API that powers Bento. After we approve your account, you create a shared-IP cluster, verify a domain, and send from that domain.

You need an approved account, a verified domain, and either a platform application token or an SMTP credential. Then send transactional mail. These docs also cover clusters, inboxes, webhooks, and tenants.

Start here

1. Create an API key for REST calls.
2. Add a domain and publish DKIM plus return-path.
3. Send with HTTP or SMTP.

We review senders before you can create a cluster or an inbox. New clusters set ip_assignment to shared.
