The WhatsApp API for your business
Every industry uses WhatsApp in its own way. See the flow, the modules and the messages that make sense for yours.
WhatsApp API for Clinics and Medical Practices
An empty chair is lost revenue: patients who don't confirm, forget, or reschedule at the last minute wreck your calendar. Automate confirmations, reminders and follow-ups on WhatsApp without relying on the front desk typing them one by one. Connect the clinic's number in minutes, send confirmations and reminders on autopilot and watch the calendar fill back up. Create a free account and test with your number.
ViewWhatsApp API for Aesthetic Clinics
Your front desk loses half the day answering 'how much is it?' and confirming appointments on WhatsApp, while clients who had a procedure 3 months ago disappear because nobody called them back. An empty chair is money that does not come back. Connect your number, let appointment confirmations and follow-up reminders go out on their own, from the schedule you already use, and free your front desk to sell. Create a free account and test today.
ViewWhatsApp API for Lawyers and Law Firms
A client messages after hours, asks about the status of their case and disappears if nobody answers quickly. Every case that slips away because of a slow reply is a fee that walks out the door. Connect the firm's number in minutes, reply instantly and hand the lawyer only qualified clients. Create a free account and test with your number.
ViewWhatsApp API for Accounting Firms
Every month is the same chase for documents, and every tax deadline turns into hunting down the client who does not answer email. The firm lives putting out fires on the partner's personal WhatsApp. Connect the firm's number, automate due-date alerts and document requests and win back your team's hours. Create a free account and test it.
ViewWhatsApp API for Real Estate Agencies
A portal lead goes cold in minutes and lands on a WhatsApp number nobody monitors. Meanwhile, agents fight over who replies first and the viewing never gets confirmed. Connect the agency's number in minutes, reply before the competitor does and send agents only to clients ready to visit. Create a free account.
ViewWhatsApp API for E-commerce
Your customer buys and then goes silent until delivery, while the abandoned cart goes cold and "where is my order?" floods support. WhatsApp solves all three, but doing it by hand doesn't scale. Connect your store to WhatsApp in minutes, automate order alerts and cart recovery and sell more without growing the team. Create a free account.
ViewWhatsApp API for Agencies (White Label)
Your agency manages WhatsApp for dozens of clients, but each one needs a separate number, its own automation and a results report. Doing it by hand, one phone at a time, doesn't scale and puts every client's chip at risk. Deliver WhatsApp service and campaigns as a recurring offer, with a single dashboard for all clients. Create a free account and set up your first operation.
ViewWhatsApp API for SaaS and Developers
You want WhatsApp inside your product, but Meta's official API is bureaucratic and charges per conversation, and running Baileys on your own server becomes technical debt nobody wants to maintain. ZapZap API gives you a managed instance, REST and webhooks, with no session or reconnection handling on your side. Create an account, scan the QR code and make your first call in minutes. Docs with ready examples and no approval queue. Create a free account and try it.
ViewWhatsApp API for Info Products and Launches
You spent weeks on the campaign and the number drops right as the cart opens, when your whole list is waiting for the link. The bottleneck in your launch was never the copy, it's the WhatsApp infrastructure that has to hold the peak. Connect your numbers before the launch, warm them up early and send at a human pace to sell more on the day that matters. Create a free account.
ViewWhatsApp API for restaurants: more orders and returning customers
Friday 8 p.m., the restaurant's WhatsApp is packed with orders, customers asking about the menu, the delivery rider asking to confirm an address and nobody keeping up. By the end of the night, half of the "yes, I'll order" messages went unanswered and became a sale lost to the competitor down the street. Connect the restaurant's number in minutes, automate orders and delivery alerts and win customers back without app commissions. Create a free account.
ViewWhatsApp API for Schools and Courses
Your front desk answers the same enrollment question fifty times a day, class notices get lost in the group chat, and tuition runs late because nobody reminded the student in time. Centralize enrollment, class communication, support and billing on WhatsApp with an API that runs on your own numbers. Connect the school's number, turn prospects into enrollments and keep students close with automatic reminders. Create a free account and test it.
ViewWhatsApp API for Gyms and Studios
Members vanish after the third month, plans expire and nobody warns them, and the trial class booked by message turns into endless rescheduling. Your gym loses memberships not for lack of new members, but because the front desk WhatsApp cannot keep up with the people already in your base. Connect the gym's number, reach out to members who went quiet and confirm trial classes automatically to get more people training. Create a free account.
ViewWhatsApp API for Pet Shops and Vet Clinics
Your grooming schedule is full of no-show gaps, owners forget their pet's vaccine date and the front desk spends the day typing confirmations on WhatsApp. ZapZap API connects your system to WhatsApp and handles reminders, confirmations and follow-ups on its own, while your team serves whoever is at the counter. Connect the pet shop's number, remind owners on the right date and sell repeat visits on autopilot. Create a free account and test with your number.
ViewWhatsApp API for Psychologists and Therapists
Silent no-shows and last-minute reschedules punch holes in your schedule and drag down the month's revenue. Session confirmation, reminders and care for patient confidentiality all live in your head, between one appointment and the next. ZapZap API automates this contact over the WhatsApp your patient already uses, and you decide what gets sent, with the care professional confidentiality calls for. Connect your practice's number, let reminders and confirmations run on their own and spend your time on the people in session. Create a free account and test it.
ViewWhatsApp API for Dentists and Dental Clinics
An idle chair because a patient did not confirm, a cleaning recall nobody remembered to book and an expensive quote gone cold in silence. Your clinic needs a WhatsApp that confirms, reminds and reactivates on its own, without a receptionist typing all day. Connect the clinic's number, send confirmations and recall reminders on their own and keep the chair busy. Create a free account and test with your number.
ViewWhatsApp API for Barbershops and Salons
An empty chair is money that never comes back. Clients forget their appointment, vanish on weekends, and you end up chasing confirmations one by one on the front desk WhatsApp. ZapZap API sends appointment confirmations, alerts the waitlist you keep when a gap opens and calls back the clients who disappeared, without you ever stopping work. Connect your number, put confirmations and reminders on autopilot and fill the empty slots. Create a free account and test with your number.
ViewWhatsApp API for Insurance Brokers
You sell the policy once, but the relationship lasts all year: quotes that go quiet, renewals that expire without a warning, clients anxious about the status of a claim. When follow-up depends on your memory, renewal commission turns into churn. ZapZap puts every stage on WhatsApp automatically, with each book of business organized by number. Connect your number, keep track of every renewal date and answer quote leads before another broker does. Create a free account and test it.
ViewWhatsApp API for travel agencies and tour operators
The client asks for a quote at 10 pm on Friday, goes quiet over the weekend and reappears on Monday buying the package from the competitor who answered first. The itinerary gets lost in email, the voucher arrives buried among 40 other messages and the traveler still calls on departure day asking where to check in. Your agency lives on urgency and WhatsApp is the channel that decides the sale. Connect the agency's number, answer travelers while they are still deciding and close more packages. Create a free account and test with your number.
ViewWhatsApp API for optical stores: sell more glasses, build loyalty
Glasses sitting ready on the bench for days and the client never shows up to pick them up. An eye exam that becomes a no-show because nobody confirmed it. ZapZap API puts your store's WhatsApp on autopilot: pickup notices, exam confirmations and lens change reminders go out on their own, without anyone typing one by one. Connect the store's number, automate pickup alerts and yearly recalls and sell more to existing clients. Create a free account and test it.
ViewWhatsApp API for Solar Energy Companies
The lead asks for an electricity bill simulation, vanishes after the quote and the site visit goes unconfirmed. The WhatsApp API for solar energy companies organizes that entire funnel: it qualifies consumption, follows up on the panel quote at the right pace, confirms the visit and turns a happy customer into a referral, all for R$15 per active number per month, with no per-message charge. Connect the company's number, qualify simulation leads and send sales reps only to people who can sign. Create a free account and test with your number.
ViewWhatsApp API for fashion and apparel stores
Your customer asks if the dress comes in size S, disappears for two days and comes back when it is already sold out. The collection launch stays stuck in a Story that 90% of your list never saw. The store's WhatsApp turns into a box of questions about size, color and shipping that nobody can answer at the moment of the sale. Connect the store's number, send news to past buyers and recover stalled sales. Create a free account and test with your number.
ViewWhatsApp API for driving schools: full calendar, fewer no-shows
The student enrolls, disappears for weeks and comes back lost about the next lesson. The CFC (driving school) front desk spends the morning calling to confirm practical lessons, announce the DETRAN (state traffic authority) exam and chase overdue installments. Every unanswered call is an idle instructor slot and an installment turning into a default. Connect the school's number, automate reminders and payment follow-ups and get students there on time. Create a free account and test with your number.
ViewWhatsApp API for lenders and credit correspondents
A credit lead replies once and vanishes. Documents arrive in pieces, the simulation is slow, the installment comes due and nobody warns. Every minute of silence is a proposal the competitor closes first. ZapZap API puts simulation, document collection, approval notices and billing to run on WhatsApp without you typing. Connect your number, reply before competitors do and hand analysts only complete proposals. Create a free account and test with your number.
ViewWhatsApp API for Nutritionists and Nutrition Clinics
Patients vanish after the first appointment, forget the follow-up and the meal plan becomes a lost PDF in the chat. You answer scheduling requests during your lunch break and still try to remember who needs a weight reassessment this month. WhatsApp became reception, medical record and post-appointment care all at once, all on your fingertips. Connect your practice's number, let reminders and check-ins run on their own and keep patients on track. Create a free account and test it.
ViewWhatsApp API for franchises and multi-unit networks
Your brand sells the same everywhere, but each franchisee answers their own way. One unit takes 3 hours, another sends a 5 minute voice note, another disappears on weekends. The lead headquarters paid to generate cools down in the hands of whoever answers without a script. Here you provision a WhatsApp number for each unit, set the service standard through the AI and the Flow Builder, and gather the network's audience into WhatsApp groups with the Gatekeeper. The network speaks one language, and you see what each city is doing. Connect each unit's number, keep the same message across the network and track everything in one place. Create a free account and test with one unit.
ViewWhatsApp API for media buyers and performance agencies
You deliver the click, the client answers on WhatsApp and nobody knows what became a sale. Meta optimizes in the dark, the report turns into chat screenshots and the client blames the campaign. Give each client a number of their own, answer the ad lead right away, record the sale and send the conversion event back to Meta, all in a dashboard the client opens on their phone without creating an account. R$15 per active number per month, no per-message fee. Create the account and connect the first number.
ViewWhatsApp API for automation and CRM resellers
You sell automation, CRM or customer service and need one WhatsApp number per client, created without manual work and delivered with your client's look. Create instances by API, store the client identifier on each one, send the connection link and deliver a portal with their name, logo and color. Your cost is R$15 per active number per month, with no per-message fee and no volume tier, so your margin is a multiplication. Create the account and test it with one client.
ViewWhatsApp API for lead and sales operations
A lead operation lives on volume: many contacts, several numbers, one team answering. A single number concentrates all the risk and all the bottleneck, and a chip that drops midday takes the target down with it. Spread sending across your numbers, answer and qualify with AI, send each lead to the CRM by webhook and keep the cost at R$15 per active number per month, with no per-message fee. Create the account and connect the first numbers.
ViewWhatsApp API for multi-location businesses
Every store, branch or clinic has its own WhatsApp, and headquarters sees none of them. One location answers in minutes, another the next day, and the customer does not know who they are talking to. Keep one number per location in one account, with AI and flows in the brand's standard, limited access for whoever answers at each site and a fixed cost of R$15 per active number per month. For franchise networks, see the franchise page too. Create the account and connect the first location.
ViewWhatsApp for agencies that build with AI
You already build automations with Claude Code, Cursor or Codex and you need a WhatsApp base your AI can read and your client can use. Here every client's numbers sit in a single dashboard, each client's ad leads are recorded, the client follows everything in a portal on their phone, appointment messages are scheduled in the chat, and the API comes with OpenAPI, Postman, SDKs, an MCP server and llms.txt. GM Solutions Hub, the agency of ZapZap's founder, uses ZapZap with its own clients. R$15 per active number per month, no per-message fee. Create the account and connect your first client.
