List Templates

List templates. This page documents the OpenSend-owned API contract for GET /templates.

GET /templates

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. Return a tenant-scoped collection. Use pagination parameters when available instead of assuming a fixed result size.

Parameters

limit and after may be used on collection routes when the route supports cursor pagination.

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.
