Webhook, template, messaggi di sessione e conformità. Guida pratica con Spoki.*\n\n---\n\nThe **WhatsApp Business API** lets you send and receive messages programmatically so you can build **chatbots**, **notifications**, and **support flows** inside your own apps. Connecting your **applications** to the **API** requires a business account, approved **templates** for outbound messages, and a way to handle **webhooks** when messages arrive.\n\nThis guide walks you through how to **connect your apps to the WhatsApp API**: setup, **templates** and **session** rules, **webhooks**, and how to stay compliant. Links to [registration](https://spoki.com/it/landing-registration), [pricing](https://spoki.com/it/pricing), [support](https://spoki.com/it/customer-support), and the [ROI calculator](https://spoki.com/it/roi-calculator)."},{"heading":"What You Need Before Connecting","level":2,"text":"You need a **WhatsApp Business Account** (or partner access), a **phone number** for the business, and a **server or service** that can receive **webhooks** and send API requests. Many teams use a platform like **Spoki** to manage the **API**, **templates**, and **opt-in** so they can focus on their app logic. For features and integrations see [Spoki features](https://spoki.com/it/features)."},{"heading":"How the WhatsApp Business API Works","level":2,"text":"You send messages via **HTTPS** to the API; you receive messages via **webhooks** (the provider calls a URL you specify when a message is sent to your number). For the **first message** to a user (or after the 24-hour **session** has expired) you must use an **approved template**. Once the user replies, you enter the **24-hour session window** and can send **session messages** (free-form) until the window closes. With **Spoki** you manage [registration](https://spoki.com/it/landing-registration), [book](https://spoki.com/it/book), and [pricing](https://spoki.com/it/pricing) and connect your app via webhooks or API. See [WhatsApp Business API](https://spoki.com/it/solutions) and [support](https://spoki.com/it/customer-support)."},{"heading":"Setting Up Webhooks","level":2,"text":"Your **webhook** URL must be **HTTPS**, respond quickly (e.g. 200 OK within a few seconds), and verify the request when the provider sends a **verification challenge**. Store incoming **messages** and **events** (read, delivered) and process them in your app (e.g. update your DB, trigger a bot reply). Never block the webhook thread with long tasks; queue work if needed. With **Spoki** you can configure webhooks and keep [registration](https://spoki.com/it/landing-registration) and consent in sync."},{"heading":"Using Templates and Session Messages","level":2,"text":"**Templates** are pre-approved message formats (e.g. “Hello {{1}}, your order {{2}} has shipped.”). Use them for the **first contact** or when re-engaging after 24 hours of inactivity. **Session messages** are for the conversation within 24 hours of the user’s last message; they don’t need pre-approval but must comply with WhatsApp policies. Design your **app** flow so the first outbound message is always a template; then switch to free-form for the rest of the session. Use the [ROI calculator](https://spoki.com/it/roi-calculator) to estimate impact. For [pricing](https://spoki.com/it/pricing), see the links provided."},{"heading":"Handling Inbound Messages in Your App","level":2,"text":"When a user sends a message, the **webhook** delivers it to your endpoint. Your **app** should: (1) identify the sender (phone number or contact ID), (2) load or create the conversation context, (3) decide the reply (e.g. from a bot, from a script, or from a human agent), and (4) send the reply via the API within the **session** window. If you take too long and the session expires, the next outbound message must use a **template**. With **Spoki** you can build these flows and connect [support](https://spoki.com/it/customer-support) and [registration](https://spoki.com/it/landing-registration) so your app and WhatsApp stay in sync."},{"heading":"Errors and Rate Limits","level":2,"text":"The **WhatsApp API** returns errors for invalid requests, missing templates, or policy violations. Handle them in your app: retry with backoff for transient errors, and fix content or template issues for permanent ones. Respect **rate limits** (messages per second per phone number) to avoid blocks. Log errors and monitor delivery so you can fix issues quickly. With **Spoki** you get a single place to manage [pricing](https://spoki.com/it/pricing), [book](https://spoki.com/it/book), and API usage."},{"heading":"Compliance and Best Practices","level":2,"text":"Respect **opt-in**: only send messages to users who have agreed to receive them. Include your **business name** and a way to **opt out** in templates. Handle **personal data** according to privacy regulations (e.g. GDPR). Store only what you need and allow users to request access or deletion. With **Spoki** you manage [registration](https://spoki.com/it/landing-registration) and consent so your **integration** stays compliant as you scale."},{"heading":"Conclusion","level":2,"text":"**Connecting your apps to the WhatsApp API** lets you automate support, notifications, and conversations. Set up **webhooks**, use **templates** for the first message and when the session has ended, and use **session messages** for the active dialogue. Keep **opt-in** and data handling compliant. With a platform like **Spoki** you can focus on your app logic while the API, templates, and consent are managed in one place."},{"heading":"Sfruttare al meglio la configurazione","level":2,"text":"Un unico pannello per la connessione all’**API WhatsApp Business**, i **template** e l’**opt-in** facilita la conformità e la scalabilità.
