TechUpServices developer API
Send WhatsApp messages and broadcasts with one simple API.
Version 1 supports direct WhatsApp sends and queued broadcasts. Use API keys from your dashboard with the same delivery engine that powers the main website.
Quick start
1. Create your API key
Go to
/dashboard/api, create a key, copy it once, and store it securely. The API requires `Authorization: Bearer <key>`.2. Call the messages endpoint
Use `POST https://api.techupservices.in/api/v1/messages/send` with one phone number, a comma-separated string, or an array of recipients. Start with text, then add template sends.
3. Queue broadcasts
Use `POST https://api.techupservices.in/api/v1/broadcasts` to queue Google Sheets, contact, list, or CSV-backed broadcasts and track progress with `GET /api/v1/broadcasts/:id`.
