Connect any OpenAI model (GPT-4o, GPT-4 Turbo, GPT-4) to your WhatsApp with function calling, CRM sync and human handoff. No markup on tokens — pay OpenAI directly. Live in 10 minutes.
If your team is already locked into OpenAI, this is the fastest way to get it on WhatsApp.
ManyChat, Landbot and others use your OpenAI but charge a markup on top of the actual Anthropic/OpenAI cost. At serious volume, this doubles or triples your monthly AI bill.
Wazzap uses your OpenAI API key directly. You pay $19/mo for the platform + whatever you consume on OpenAI ($30-$120/mo typical). No surprises, no upsells, no hidden markup.
If you want your own agent with function calling on WhatsApp + CRM, you end up with a long project: function schemas, streaming, hosting, maintenance, error handling.
20+ native functions (compatible with Claude MCP): book, qualify, transfer, move pipeline, export. You choose which functions your agent can call. No code.
Most AI platforms on WhatsApp lock you into one provider. If OpenAI raises prices, drops quality or has downtime, you're stuck.
Wazzap supports OpenAI and Claude as first-class. Switch models with a toggle, per agent or per flow. No migration, no lock-in. Start with GPT-4o, test Claude, decide.
Access OpenAI's full catalog: GPT-4o (multimodal, fast), GPT-4 Turbo (more capable), GPT-4 (standard), GPT-3.5 (budget). Switch models with a toggle based on your use case.
The same function catalog as Claude MCP — but implemented with OpenAI function calling. Your GPT agent can book, qualify, move pipelines and more. Plug-and-play.
The customer sends a photo via WhatsApp and GPT-4o analyzes it: an invoice, a product, a screenshot, a photo of an issue. Smart replies based on the image — no OCR, no manual preprocessing.
The bot detects when to escalate to a human (complaint, high intent, frustration). Hands off with a context summary. Combinable: GPT-4o for complexity, GPT-3.5 for FAQs, human when needed.
No code, no building function schemas, no handling streaming.
You generate it at platform.openai.com (5 minutes). Paste it into Wazzap. If you don't have an account, we walk you through it. You pay tokens directly to OpenAI — Wazzap charges no markup.
Choose the model (GPT-4o recommended). Set the tone (formal, friendly). Activate which functions it can call (book, qualify, transfer). Upload your knowledge base (PDFs, URLs, FAQs).
Activate it on your number. Every conversation + every function call is logged. You can step in, tweak the prompt, switch models. Iterate with real data.
"My team was already locked into OpenAI for all our assistants and embeddings. Wazzap let us plug GPT-4o into WhatsApp in an afternoon without migrating any of the stack we already had."
"GPT-4o's vision capability changed my support: the customer sends a photo of the issue, GPT analyzes it and replies with the fix. Automatically resolved cases went up 40%."
"I compared Wazzap against ManyChat with the GPT add-on. Same model quality, but ManyChat charged me 3x the actual token cost. I migrated and saved $150/mo on my AI bill."
3 ways to get GPT answering WhatsApp — compared with real data.
| Wazzap + OpenAI | ManyChat / Landbot with GPT | Build custom | |
|---|---|---|---|
| Setup time | 10 minutes | 1-3 days | 2-4 months |
| Platform cost | $19/mo | $25-$300/mo | $$$$ developer |
| Markup on OpenAI tokens | 0% | 2-5x | 0% |
| Advanced function calling | ✓ 20+ functions | Limited | You build it |
| GPT-4o vision | ✓ Built-in | Limited | You build it |
| Multi-model (Claude + GPT) | ✓ Free toggle | ✗ Lock-in | You build it |
| CRM sync | ✓ Native (HighLevel/Chatwoot) | Via Zapier | You build it |
| Integrated human handoff | ✓ Smart | Manual | You build it |
| Built-in anti-ban | ✓ Spintax + proxies | ✗ | You build it |
| Response latency | 1-3 seconds | 3-10 seconds | Variable |
When NOT to use OpenAI in Wazzap? If your agent needs complex actions with multiple parallel tools, Claude MCP usually wins on reasoning quality. For simple FAQs + vision + cost-optimized setups, GPT-3.5 or GPT-4o are an excellent choice.
All these integrations come included in the same plan.
Alternative with native MCP. Combinable — toggle between the two.

See plans and pricingYes. You need a platform.openai.com account (free to create) and an API key. Token costs are paid directly to OpenAI — Wazzap charges no markup.
For 200-500 chats/day with GPT-4o, the typical cost is between $30 and $120 USD/mo in tokens. GPT-3.5 is ~10x cheaper if your case allows it. GPT-4o has a reasonable price and much better quality than GPT-3.5.
Every model available via API: GPT-4o, GPT-4 Turbo, GPT-4, GPT-3.5 Turbo, and embeddings (text-embedding-3 series). When OpenAI ships new models, we integrate them within days.
Yes. When a customer sends a photo via WhatsApp, GPT-4o analyzes it and replies based on what it sees. Useful for: invoice analysis, product identification, screenshots, photos of issues for support.
Yes. We support both as first-class. Toggle per agent, per flow or per message type. Native functions work with both models.
No. 0% markup. You pay $19/mo to Wazzap for the platform, and tokens go directly to OpenAI based on your usage. This is one of the reasons customers migrate from ManyChat (which charges a 2-5x markup).
Yes, we support invoking Assistants via API. If you already have Assistants configured in OpenAI with your knowledge base, you can point to them directly from Wazzap — no need to rebuild anything.
