Questions we get asked most often about WhatsApp Business API, bulk SMS, OTP delivery, DLT compliance, IVR, lead generation and implementation timelines — answered clearly.
The WhatsApp Business API is designed for medium to large businesses that need to send messages at scale, automate conversations and integrate WhatsApp into their CRM or backend systems. Unlike the regular app, the API does not have a native interface — it operates through platforms and partners like WEBozINDIA, enabling template-based messaging, two-way journeys and automation triggers. The app is limited to a single device and manual operation.
For most businesses, WhatsApp API setup takes between 3 and 7 business days from the time we receive your business documents and Facebook Business Manager details. This includes account verification, phone number registration and initial template submission. Template approval from WhatsApp typically takes 24 to 48 hours.
You can send pre-approved template messages for notifications, alerts, order updates, appointment reminders, OTPs, and marketing campaigns (with user opt-in). Once a user replies, you can have a free-form two-way conversation within a 24-hour session window. Rich media — images, videos, PDFs, buttons and list messages — are all supported.
Promotional SMS is used for marketing purposes — offers, campaigns, product launches and event announcements. It is governed by TRAI DLT rules and typically cannot be sent to DND numbers. Transactional SMS is used for service-related communication like OTPs, booking confirmations, payment alerts and account updates. Transactional messages can be sent to DND numbers and have stricter content requirements.
Promotional SMS cannot be sent to numbers registered on the TRAI National DND registry. Transactional SMS — for OTPs, alerts, and service updates — can reach DND numbers because they carry service-critical information the user has consented to receive. We help you route messages correctly from the start to avoid delivery failures and compliance issues.
For transactional SMS, delivery typically happens within 1 to 5 seconds of submission for most operators. Promotional SMS has slightly longer delivery windows depending on operator load and time of day. Our infrastructure is built with multiple operator routes and fallback logic to maintain high delivery rates even during peak traffic.
DLT (Distributed Ledger Technology) is TRAI's mandatory compliance framework for commercial SMS in India. Every business that sends promotional or transactional SMS must register as a Principal Entity on a TRAI DLT platform, register their sender IDs (header) and pre-register all message templates. Without DLT registration, your messages will be blocked by operators. We handle the entire registration process for you.
Typically you need: your company's GST registration certificate, PAN card, authorized signatory details, company incorporation or LLP certificate, and a signed authorization letter. WEBozINDIA guides you through the exact document list for your business type and manages submission and follow-up with the DLT platform.

That depends on the workflow. We can qualify the lead, send automated follow-up, route it to the right sales owner, push it into CRM and track the outcome for reporting.
Pricing varies by service, volume and configuration. Bulk SMS is typically priced per message based on monthly volume brackets. WhatsApp API has a per-conversation pricing model set by Meta, plus our service fee for setup, management and automation. IVR and voice services are priced per minute or per call. We share a detailed proposal once we understand your use case and expected volumes — no hidden charges.
There is no rigid long-term lock-in for most services. Bulk SMS operates on a prepaid credit model — you top up as you go. WhatsApp API setup involves a one-time onboarding fee, then ongoing service charges based on usage. We are straightforward about what you are committing to before any work begins.
Yes. For most services, we can run a small test batch before you commit to a full rollout. This lets you verify delivery quality, check template formatting and confirm integration points work as expected. Reach out and we will set up a test run suited to your use case.
