Best practices for registration, scope, opt-out, and storage with Spoki and the WhatsApp Business API.*\n\n---\n\n**Opt-in** and **consent** are the foundation of compliant **WhatsApp** messaging. The **WhatsApp Business API** and **Spoki** require that you only message users who have agreed to receive messages. This guide covers **best practices** for collecting, storing, and respecting **opt-in** and **opt-out** so your **campaigns**, **support**, and **reminders** stay within the rules.\n\nYou will find links to [registration](https://spoki.io/registration), [pricing](https://spoki.io/pricing), [support](https://spoki.io/support), [book](https://spoki.io/book), and the [ROI calculator](https://spoki.io/roi-calculator)."},{"heading":"Why Opt-In and Consent Matter","level":2,"text":"**WhatsApp** and local laws (e.g. **GDPR**, telecom rules) require that businesses obtain **consent** before sending **WhatsApp** messages. Sending without **opt-in** can lead to **opt-out**, blocks, or policy violations. **Spoki** helps you store **opt-in** and process **opt-out** so every message you send is backed by clear **consent**. See [registration](https://spoki.io/registration) and [support](https://spoki.io/support).\n\n**What counts as opt-in:** The user must take a clear action (e.g. tick a box, click “Send me **WhatsApp** updates”, reply YES to a **template**) and understand what they will receive. Pre-ticked boxes or vague wording are not enough. **Spoki** and your **CRM** can record the date, source, and scope of **opt-in** so you have proof of **consent**. Use [book](https://spoki.io/book) for **consent** flow design."},{"heading":"Collecting Opt-In: Where and How","level":2,"text":"**Registration and forms:** When users **register**, subscribe, or fill a form (on your website, **Facebook**, or **Instagram**), ask explicitly: “Do you want to receive **WhatsApp** messages from us? (e.g. **order** updates, **support**, **offers**).” Store their **phone number** and **opt-in** (date, source, scope) in your **CRM** or **Spoki**. **Spoki** can sync with your **CRM** so **campaigns** and **support** only target contacts with **opt-in**. See [pricing](https://spoki.io/pricing) and the [ROI calculator](https://spoki.io/roi-calculator).\n\n**At point of action:** When a customer **books** an **appointment**, places an **order**, or requests **support**, ask: “Can we contact you via **WhatsApp** for confirmations and updates?” Record **opt-in** with the **booking** or **order** so you can send **templates** (e.g. **booking** confirmation, **order** status) only to those who agreed. **Spoki** helps you manage **opt-in** per use case (e.g. **support** only vs **marketing**). Use [support](https://spoki.io/support) for **consent** flows.\n\n**Double opt-in (optional):** For **marketing** or **campaigns**, you can send an **approved template** that asks the user to confirm (e.g. “Reply YES to receive **offers** via **WhatsApp**.”). Once they reply, you have a clear record of **opt-in**. **Spoki** delivers the **template** and can forward their reply to your **webhook** so you update your **CRM**. See [registration](https://spoki.io/registration) and [book](https://spoki.io/book)."},{"heading":"Scope and Transparency","level":2,"text":"**Scope:** Tell users exactly what they will receive (e.g. “**Order** and **shipping** updates”, “**Support** replies”, “**Campaigns** and **offers**”). Do not use **opt-in** for one purpose (e.g. **support**) to send another (e.g. **marketing**) unless they have agreed to both. **Spoki** helps you segment by **opt-in** scope so **templates** and **campaigns** match **consent**. See [pricing](https://spoki.io/pricing) and [support](https://spoki.io/support).\n\n**Transparency:** In your **privacy policy** or **terms**, state that you use **WhatsApp** for the purposes you described and that users can **opt-out** at any time (e.g. by replying STOP). **Spoki** processes **opt-out** so your lists stay clean; your **CRM** or **app** should also update when **opt-out** is received. Use the [ROI calculator](https://spoki.io/roi-calculator) to plan volume while respecting **opt-out** rates."},{"heading":"Managing Opt-Out","level":2,"text":"**In every message (or first of a series):** Include a short line such as “Reply STOP to unsubscribe” so users know how to **opt-out**. **Spoki** can detect **opt-out** (e.g. STOP, UNSUBSCRIBE) and update your list or forward the event to your **webhook**. Your **app** or **CRM** must then stop sending to that contact. See [support](https://spoki.io/support) and [book](https://spoki.io/book).\n\n**Honour opt-out immediately:** Once a user **opts out**, do not send them any more **WhatsApp** messages unless they **opt-in** again. **Spoki** helps you respect **opt-out** so **campaigns** and **support** stay compliant. Store **opt-out** with the contact so future **campaigns** skip them. Use [registration](https://spoki.io/registration) for **opt-out** handling."},{"heading":"Storing and Syncing Consent with Spoki","level":2,"text":"**Spoki** can store **opt-in** and **opt-out** for contacts you message. When you **connect** your **CRM** or **app** to **Spoki** (via **API** or **webhook**), keep **consent** in sync: when a user **opts in** on your site, add them in **Spoki** with the right scope; when they **opt-out** via **WhatsApp**, **Spoki** can notify your **webhook** so you update your **CRM**. This way **templates** and **campaigns** only go to contacts with valid **opt-in**. See [registration](https://spoki.io/registration) and [support](https://spoki.io/support).\n\n**Audit trail:** Keep a record of when and how each contact **opted in** (and **opted out** if applicable). This helps you demonstrate **consent** if asked and avoids messaging users who have **opted out**. **Spoki** and your **CRM** can maintain this **audit** so **WhatsApp** messaging stays compliant. Use [book](https://spoki.io/book) and [pricing](https://spoki.io/pricing) for **consent** and **CRM** setup."},{"heading":"Refreshing and Re-consent","level":2,"text":"Over time, **consent** can become outdated (e.g. **privacy** policy or use cases change). Where relevant, consider asking users to confirm **opt-in** again (e.g. via an **approved template**: “We’ve updated how we use **WhatsApp**. Reply YES to keep receiving messages.”). **Spoki** helps you send **templates** and record renewed **opt-in** so your **consent** stays current. Keep a log of **re-consent** dates in your **CRM** or **Spoki**. Use [support](https://spoki.io/support) and [book](https://spoki.io/book) for **re-consent** flows."},{"heading":"Pitfalls to Avoid","level":2,"text":"- **Assuming consent:** Do not message users just because they gave you their **phone number** or contacted you once. You need explicit **opt-in** for **WhatsApp** messages. **Spoki** helps you check **opt-in** before sending so **campaigns** stay compliant.\n\n- **Unclear scope:** Do not collect a generic “**WhatsApp** updates” and then send **marketing** if they only agreed to **order** updates. Be specific and segment in **Spoki** and your **CRM**.\n\n- **Ignoring opt-out:** When a user sends STOP, process it right away and stop all **WhatsApp** messages. **Spoki** can automate **opt-out** handling; **connect** your **webhook** so your **CRM** is updated. See [support](https://spoki.io/support) and [registration](https://spoki.io/registration)."},{"heading":"Conclusion","level":2,"text":"**Opt-in** and **consent** are non-negotiable for **WhatsApp** messaging. Collect **opt-in** clearly, define scope, honour **opt-out**, and keep **consent** in sync with **Spoki** and your **CRM**. **Spoki** works with the **WhatsApp Business API** so you manage **opt-in** and **opt-out** in one place.\n\nReady to get **opt-in** right?
