**Step 1: Log in to your DoubleTick account**\ Open the DoubleTick login page and enter your registered login phone number. Enter the OTP received, and log in using **Primary Owner access**. **Step 2: Go to Manage Channels in Settings**\ On the left side, hover over the navigation panel and click on **Settings**. Inside Settings, click on **Manage WABA**. **Step 3: Click on "Add Number"**\ On the top-right corner, click the green **Add Number** button. **Step 4: Choose Embedded Signup method**\ In the pop-up, click **Add Number using Embedded Signup**. When asked to choose an onboarding method, select the second option, **Connect WhatsApp API Number**, then click **Confirm and Proceed**. **Step 5: Log in to Facebook**\ Meta will redirect you to Facebook. If you're already logged in, it will show **Continue with \[Your Profile Name]** — click **Continue**. **Step 6: Select Business Portfolio**\ Click the dropdown and select the portfolio where you want to onboard this new number. Business Name, Website, and Country will auto-fill from the selected portfolio. Click **Next**. **Step 7: Select or create WhatsApp Business Account (WABA)**\ If you want to add the number to an existing WABA, select it from the dropdown. If you want to create a new WABA instead, choose **Create a New WhatsApp Business Account**. **Step 8: Select or create WhatsApp Business Profile**\ Use an existing profile, or click **Create a New WhatsApp Business Profile**, then click **Next**. **Step 9: Enter business profile details**\ Fill in the WhatsApp Business Account Name, Display Name, and Business Category, then click **Next**. **Step 10: Add your new phone number**\ Click **Add a New Number**, select your country code, and enter the new phone number you want to onboard. {% hint style="warning" %} The number must **not** be active on WhatsApp Messenger or the WhatsApp Business App. It should be unused at the time of onboarding. {% endhint %} **Step 11: Verify the number**\ Choose a verification method — **Text Message (SMS)** or **Phone Call** — and click **Next**. Enter the OTP received via your chosen method.
**Step 12: Finish onboarding**\ After OTP verification, click **Finish**. Meta will show "Connecting your account with DoubleTick…", and once complete, your number will reflect as **Connected Successfully**. Your additional phone number is now onboarded and ready to be used inside DoubleTick for messaging, campaigns, automation, and support. #### Key takeaways * This flow is for adding a new WhatsApp API number to a DoubleTick account that already has at least one number connected. * You must be logged in with Primary Owner access to complete this process. * The number must not be active on WhatsApp Messenger or the WhatsApp Business App before onboarding. * You can either use an existing WABA and Business Profile, or create new ones during onboarding. #### FAQs **Do I need Primary Owner access to onboard an additional number?**\ Yes. You must be logged in with Primary Owner access to complete this process. **Can I add the new number to my existing WABA?**\ Yes. When prompted, choose your existing WhatsApp Business Account instead of creating a new one. **What happens if the number is already active on WhatsApp?**\ Onboarding will fail. The number must not be active on WhatsApp Messenger or the WhatsApp Business App before you start. **How do I verify the new phone number?**\ Choose Text Message or Phone Call as your verification method, then enter the OTP you receive. **How do I know the number connected successfully?**\ After clicking Finish, the number will reflect as **Connected Successfully** once DoubleTick finishes connecting the account. #### Related topics * [How to onboard a phone number on Cloud API](/get-started-with-doubletick/onboarding/how-to-onboard-a-phone-number-on-cloud-api.md) * [Prerequisites for Onboarding](/get-started-with-doubletick/prerequisites-for-onboarding.md) * [How to Manage Channels](/settings/how-to-manage-channels.md) --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://learn.doubletick.io/get-started-with-doubletick/onboarding/onboard-an-additional-waba-on-cloud-api.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
