Everything about WhatsApp message templates: categories, creation, approval process, examples by industry, and best practices.
Step-by-step troubleshooting for WhatsApp Business API signup — switching BSPs, deleting numbers, creating new WABAs, and registering numbers.
Setting up WhatsApp Business API through WhatsTeam should be a straightforward process, but certain situations can cause complications during signup. Whether your number is already connected to another Business Solution Provider (BSP), registered on a personal WhatsApp account, or linked to a different Meta portfolio, each scenario requires a specific resolution path.
This comprehensive guide walks you through the most common issues encountered during WhatsApp signup and provides clear, step-by-step instructions to resolve them so you can get your business up and running on WhatsTeam as quickly as possible.
Before starting the WhatsApp signup process on WhatsTeam, make sure you have the following items ready. Completing this checklist beforehand will save you time and prevent the most common blockers.


Tip: Having all these items prepared before you begin will dramatically reduce the likelihood of encountering errors during the signup process.
One of the most frequent issues occurs when your phone number is already registered with another WhatsApp Business Solution Provider (BSP). WhatsApp enforces a strict one-provider-per-number policy, meaning a single phone number can only be active on one BSP at any given time.

You will typically see one of the following error messages during signup:
This situation arises when:

The resolution depends on your current setup. You have two main paths:
Both paths are described in detail in the following sections.
If your number is currently managed by another BSP and you want to move it to WhatsTeam, you need to perform a formal migration. This process involves coordination between your current provider, Meta, and WhatsTeam.

| Factor | Migration (Same WABA) | Fresh Start (New WABA) |
|---|---|---|
| Templates | Preserved | Must recreate |
| Messaging limit | Preserved | Starts at 1K/day |
| Quality rating | Preserved | Starts fresh |
| Display name | Preserved | Must re-approve |
| Downtime | Minutes | Minutes to hours |

Recommendation: Whenever possible, migrate using the same WABA to preserve your messaging limits and template approvals. This is especially important for businesses with high daily message volumes.
Before you can register your number on WhatsTeam, you must remove it from its current WhatsApp account. The process differs depending on whether your number is on the Cloud API or you plan to use Coexistence mode.
The Cloud API path involves completely removing the number from its current WhatsApp registration so it can be freshly registered on WhatsTeam.




Warning: Deleting a phone number from a WABA is permanent. All message history, active conversations, and pending messages associated with that number will be lost. Make sure you have exported any necessary data before proceeding.

If the number was also used on the WhatsApp or WhatsApp Business mobile app:

The Coexistence path allows you to keep using the WhatsApp Business mobile app on your phone while simultaneously connecting the same number to WhatsTeam through the Cloud API. This is ideal for businesses that want to maintain their existing WhatsApp presence while gaining API capabilities.

Coexistence only works with the WhatsApp Business app (green icon with a "B"), not the standard WhatsApp consumer app. If you are using the regular WhatsApp app, you must first migrate to the WhatsApp Business app.

Before connecting through Coexistence, disable all auto-reply features in your WhatsApp Business app:
Unlike the Cloud API path, you should not delete the number from the mobile app. The number stays active on the app while you connect it to WhatsTeam through the Embedded Signup process.
With the mobile app still active, proceed to the WhatsTeam signup process. During the Embedded Signup, select the Coexistence option when prompted. Detailed steps for this process are covered in our dedicated Coexistence guide.

If you are starting fresh or your previous account cannot be recovered, you will need to create a new WhatsApp Business Account. There are two primary methods to do this through WhatsTeam.
The Embedded Signup (ES) flow is the fastest and most recommended method. It creates your Meta Business Account and WhatsApp Business Account in a single streamlined process directly within the WhatsTeam platform.





If you prefer to create your WhatsApp Business Account directly through Meta before connecting to WhatsTeam, you can do so via the Meta Business Suite.



When using Coexistence mode, you may need to link your WhatsApp Business Account to a specific Meta Business Portfolio. This step ensures that the WABA is properly associated with your business identity and that billing, permissions, and compliance are correctly configured.


After linking, verify that:

In some cases, you may need to register a phone number that was previously used on a different WhatsApp account. This process requires careful execution to avoid errors.

Before attempting to re-register a number:
Go to Meta Business Suite and verify the number does not appear under any WhatsApp Business Account. If it still shows up, complete the deletion process described earlier in this guide.



The release process is usually instant once you delete the number from the previous WABA. However, in some cases, Meta's systems may take up to 24 hours to fully propagate the change. If you still encounter issues after 24 hours, contact WhatsTeam support at support@whats.team.
Yes, this is exactly what Coexistence mode enables. You can keep using the WhatsApp Business mobile app while also sending and receiving messages through WhatsTeam's API. However, there are some feature limitations in Coexistence mode. Refer to our dedicated Coexistence guide for full details.
If you keep the same WABA, your approved templates will be preserved. If you create a new WABA, you will need to submit all templates for approval again, which can take up to 24 hours per template.
If you delete a number from a WABA and register it under a new WABA, your messaging limit resets to the default tier (typically 1,000 business-initiated conversations per 24 hours). To preserve your messaging tier, migrate the number within the same WABA whenever possible.
This error usually indicates a temporary issue with Meta's verification service. Try the following:
Yes, a brief "Pending" status is normal while Meta processes the registration. This typically resolves within 5-15 minutes. If the status remains "Pending" for more than an hour, try refreshing your connection in the WhatsTeam dashboard or contact support.
