Webhooks, API integration, and step-by-step setup for business messaging.*\n\n---\n\nConnecting your **apps**, **CRM**, or **e-commerce** platform to the **WhatsApp Business API** lets you send and receive **WhatsApp** messages from your own systems: **order** notifications, **support** replies, and **campaigns** in one place. With **Spoki** you get a simple path to **API** access, **webhooks**, and **template** management so your integration stays compliant and scalable.\n\nThis guide explains how to **connect your apps** to the **WhatsApp Business API**, what you need (account, **templates**, **webhooks**), and how **Spoki** helps. You will find links to [registration](https://spoki.io/registration), [pricing](https://spoki.io/pricing), [support](https://spoki.io/support), and the [ROI calculator](https://spoki.io/roi-calculator)."},{"heading":"What You Need Before Connecting","level":2,"text":"**Checklist:**\n\n- **WhatsApp Business API** access (e.g. via **Spoki**). You need a verified business and a **phone number** for **WhatsApp**.\n\n- **Approved templates** for outbound messages outside the **24-hour session**. **Spoki** guides you through **template** creation and approval.\n\n- **Opt-in:** Only message users who have agreed to receive **WhatsApp** messages. Store consent in your **CRM** or **Spoki**. See [registration](https://spoki.io/registration) and [support](https://spoki.io/support) for consent flows.\n\n- **An app or system** that can send **HTTP** requests (e.g. **REST API**) or receive **webhooks**. Most **CRMs**, **e-commerce** platforms, and custom apps support this.\n\n**Spoki** provides the **API** layer and **webhook** endpoints so you can **connect** your existing tools without building everything from scratch. Check [pricing](https://spoki.io/pricing) and [book](https://spoki.io/book) for your use case."},{"heading":"How the WhatsApp Business API and Spoki Work Together","level":2,"text":"The **WhatsApp Business API** has two main ways your **apps** interact with it:\n\n- **Outbound:** Your **app** sends a request (e.g. via **Spoki** or the provider’s **API**) to send a **template** or **session** message. **Templates** are for the first message or after the **24-hour** window; **session** messages are for replies within **24 hours** of the user’s last message.\n\n- **Inbound:** When a user sends a **WhatsApp** message, the **API** can send a **webhook** to your **app** (e.g. your server or **Spoki**). Your **app** then processes the message, updates the **CRM**, or triggers a reply.\n\n**Spoki** sits between your **apps** and the **WhatsApp Business API**: you **connect** your **CRM**, **e-commerce**, or custom code to **Spoki**, and **Spoki** handles **templates**, **sessions**, and **opt-in** so you stay compliant. Use [registration](https://spoki.io/registration) to get started and [support](https://spoki.io/support) for integration help."},{"heading":"Step-by-Step: Connecting Your App with Spoki","level":2,"text":"**1. Create your Spoki account and connect WhatsApp**\n\nComplete [registration](https://spoki.io/registration) and link your **WhatsApp** Business number. **Spoki** will guide you through business verification and **template** submission so you can send **approved** messages.\n\n**2. Get your API credentials and webhook URL**\n\nFrom **Spoki** you get **API** credentials (or **webhook** configuration) to send messages and receive **inbound** events. Your **app** will call **Spoki** to send **templates** or **session** messages, and **Spoki** can forward **inbound** messages to your **webhook** URL so your **app** can react (e.g. log in **CRM**, reply automatically).\n\n**3. Implement send and receive in your app**\n\n- **Send:** When your **app** needs to send a **WhatsApp** message (e.g. **order** confirmed, **support** reply), it calls **Spoki**’s **API** with the **template** name and parameters or the **session** message content. **Spoki** handles delivery and **24-hour** rules.\n\n- **Receive:** Configure your **webhook** in **Spoki** so **inbound** messages are posted to your **app**. Your **app** parses the event, updates your database or **CRM**, and can trigger a reply via **Spoki** within the **session** window. See [book](https://spoki.io/book) and [support](https://spoki.io/support) for examples.\n\n**4. Respect opt-in and templates**\n\nOnly send to users who have given **opt-in**. For the first message or after **24 hours** of inactivity, use only **approved templates**. **Spoki** helps you manage **opt-in** and **templates** so your **app** integration stays within WhatsApp’s policies. The [ROI calculator](https://spoki.io/roi-calculator) helps you estimate volume and cost."},{"heading":"Common Use Cases: CRM, E-Commerce, Support","level":2,"text":"- **CRM:** Your **CRM** sends **Spoki** a request when a **lead** opts in or when you want to send a **template** campaign. **Inbound** messages are sent to your **CRM** via **webhook** so agents see the full thread. **Spoki** and your **CRM** keep **opt-in** and **session** logic in sync. Links: [registration](https://spoki.io/registration), [pricing](https://spoki.io/pricing).\n\n- **E-commerce:** **Order** confirmation, **shipping** update, or **support** follow-up: your **e-commerce** platform calls **Spoki** to send **templates** or **session** messages. **Inbound** messages (e.g. “Where is my order?”) hit your **webhook**; your **app** can reply via **Spoki** within **24 hours**. Use [support](https://spoki.io/support) and [book](https://spoki.io/book) for design help.\n\n- **Support:** Incoming **WhatsApp** messages are delivered to your **app** via **webhook**. Your **app** can assign the chat to an agent, show history from your **CRM**, and send replies through **Spoki** as long as the **session** is active. After **24 hours**, the next outbound message must be a **template**. **Spoki** keeps this clear so your **app** does not break the rules."},{"heading":"Pitfalls to Avoid","level":2,"text":"- **Sending without opt-in:** Your **app** must only send to users who have consented. **Spoki** helps you store and check **opt-in** so your **API** or **webhook** logic stays compliant.\n\n- **Using free-form for the first message or after 24h:** The **API** requires **approved templates** in those cases. Your **app** should call **Spoki** with the correct **template** name and parameters; **Spoki** handles the rest.\n\n- **Ignoring webhook security:** Validate **webhook** requests (e.g. signature or token) so only **Spoki** can post to your **app**. **Spoki** and [support](https://spoki.io/support) can guide you.\n\n- **Not handling opt-out:** When a user sends STOP, your **app** must process it (e.g. update **CRM**, stop sending). **Spoki** can forward **opt-out** events to your **webhook** so your **app** stays compliant. See [pricing](https://spoki.io/pricing) and [registration](https://spoki.io/registration) to scale."},{"heading":"Testing and Going Live","level":2,"text":"Before going live, test your **webhook** with sample **inbound** events and confirm your **app** sends **templates** and **session** messages correctly. Use a staging or test number if **Spoki** offers one, and verify **opt-in** is checked before every send. Monitor the first days for delivery errors and **webhook** timeouts; **Spoki** and [support](https://spoki.io/support) can help you tune retries and timeouts. The [ROI calculator](https://spoki.io/roi-calculator) helps you plan capacity as you scale **API** and **webhook** traffic."},{"heading":"Conclusion","level":2,"text":"**Connecting your apps** to the **WhatsApp Business API** with **Spoki** gives you a single **API** and **webhook** layer for **templates**, **session** messages, and **opt-in**. Your **CRM**, **e-commerce**, or custom **app** can send and receive **WhatsApp** messages while **Spoki** keeps you within the rules.\n\nReady to **connect** your **apps**?
