Integration Methods
Option 1: REST API (per platform)
There is no single HTTP endpoint that accepts “all platforms in one request”. Each checker uses POST https://api.checknumber.ai/v1/tasks with a different task_type (for example ws for WhatsApp, tg for Telegram, viber for Viber, facebook for Facebook). See the matrix on the CheckNumber API documentation.
Example — submit a Telegram batch:
curl --location 'https://api.checknumber.ai/v1/tasks' \
--header 'X-API-Key: YOUR_KEY' \
--form 'file=@"./numbers.txt"' \
--form 'task_type="tg"'
Poll with POST /v1/gettasks and task_id for every product; download when status is exported.
Option 2: No-Code CSV Upload
- Create a CSV with phone numbers
- Upload to platform dashboard
- Select which platforms to check
- Download results with account status
Option 3: Bulk Callback (Recommended)
Provide a callback URL to receive results as they complete—ideal for large batches.

FAQ
Q: Which platform should I check first? A: Start with WhatsApp (covers 80%+ of contacts globally). Layer Telegram for tech audiences, Viber for Eastern Europe, and Facebook for email-to-account verification.
Q: Can I check all 45+ platforms in a single batch? A: Not in one request. Each platform requires a separate batch task (task_type). However, you can submit parallel tasks and merge results afterward. CheckNumber.AI handles millions of parallel checks daily.
Q: How accurate are these checks? A: Accuracy depends on platform APIs and network conditions. WhatsApp and Telegram typically report 95%+ accuracy; regional platforms vary by market penetration.
Q: What if my contact list has duplicates across platforms? A: Use deduplication logic in your ETL pipeline. Compare phone numbers + platform before storing results to avoid double-charging.
