Bulk jobs run in the background. Follow this 3-step process.

Step 1: Submit Job

Option A: Upload File

POST /api/v1/bulk/file

{ "emails": ["a@b.com", ...], "webhook_url": "https://yoursite.com/callback" }

Step 2: Check Progress

Poll this endpoint until status: "complete".

Returns: { "status": "processing", "progress": 45 }
