Publish Template

Publish a draft template. This page documents the OpenSend-owned API contract for POST /templates/{id}/publish.

POST /templates/{id}/publish

Authentication

Use an OpenSend API key in the Authorization header. Dashboard session cookies are not API credentials for public API clients.

http

Authorization: Bearer os_YOUR_API_KEY

When to use it

Template routes manage stored email templates. Published templates can be used by sends and broadcasts; draft and preview behavior depends on the renderer metadata stored with the template. Publish the current draft state so application sends can use the template intentionally.

Parameters

Path parameters identify the tenant-scoped resource. JSON body fields are validated by the route before any database write.

Request example

json

{
  "name": "Welcome",
  "subject": "Welcome to OpenSend",
  "html": "<p>Hello {{name}}</p>"
}

Response

Successful responses return JSON scoped to the authenticated tenant. A representative response shape is:

json

{
  "id": "template_123",
  "name": "Welcome",
  "status": "draft"
}

Errors

OpenSend returns structured errors for missing authentication, validation failures, not-found resources, quota/rate-limit conditions, and unexpected server failures. Treat 404 as either missing or not owned by the caller.

Self-hosting notes

Self-hosted deployments can use the same path on their own OPENSEND_BASE_URL. Run migrations before deploying code that expects new fields, and keep API keys in a secrets manager instead of committing them to source control.
