Delete Contact

DELETE /contacts/{contact_id}

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_KEY

When to use it

Contact routes manage audience records for the authenticated tenant. Segment and topic relationship endpoints only affect the target contact and never expose another tenant's audience data. Delete or detach the target record for the authenticated tenant. Treat deletes as irreversible unless the resource-specific docs state otherwise.

Parameters

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

Request example

{
  "email": "ada@example.com",
  "firstName": "Ada",
  "lastName": "Lovelace"
}

Response

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

{
  "id": "contact_123",
  "email": "ada@example.com",
  "subscribed": true
}

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.
