        "filename": "Receipt-123.pdf",
        "caption": "Your receipt is attached" }'

Send a verification code (OTP)

We generate the code, WhatsApp it to the number, and check it for you — no need to build code generation yourself.

curl -X POST https://wa.dynamicsoft.biz/api/v1/otp/send \
  -H "Authorization: Bearer wak_xxxxxxxx_yourkey" -H "Content-Type: application/json" \
  -d '{ "to": "923001234567" }'

Options: length (4–8), ttl_seconds, template (must contain {{code}}).

Verify the code

When the user types the code back, verify it (no WhatsApp number needed):

curl -X POST https://wa.dynamicsoft.biz/api/v1/otp/verify \
  -H "Authorization: Bearer wak_xxxxxxxx_yourkey" -H "Content-Type: application/json" \
  -d '{ "to": "923001234567", "code": "123456" }'

Returns { "valid": true|false, "attemptsLeft": n }. Codes are single-use, expire, and are attempt-limited.

curl https://wa.dynamicsoft.biz/api/v1/status -H "Authorization: Bearer wak_xxxxxxxx_yourkey"
