OpenSend docs
List Broadcasts
List broadcasts. This page documents the OpenSend-owned API contract for GET /broadcasts.
GET /broadcasts
Authentication
Use an OpenSend API key in the Authorization header. Dashboard session cookies are not API credentials for public API clients.
Authorization: Bearer os_YOUR_API_KEYWhen to use it
Broadcast routes manage newsletter-style sends for an audience. They operate on the authenticated tenant and use the same contact, segment, topic, and suppression data as the dashboard. 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:
{
"id": "broadcast_123",
"name": "Product update",
"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.
