Whatsapp Integration - Zoho Desk Knowledgebase

Integrating WhatsApp with Zoho Desk



WhatsApp is the world's most widely used instant messaging (IM) service app, with over 2 billion users. The ubiquity of this app is reason enough for businesses of all sizes to look at it as a channel for customer support. If your customers frequently contact your business through WhatsApp, you'll find significant benefit in integrating your WhatsApp Business Account with your Zoho Desk portal.

By integrating the WhatsApp IM feature, your agents can view WhatsApp conversations within Zoho Desk and respond to them right away. This feature also facilitates the conversion of WhatsApp conversations into tickets for your agents to work upon.




What is an embedded signup?

Embedded Signup is a way for Zoho Desk to let you onboard to the WhatsApp Business API directly from our website. This embedded signup process reduces the onboarding time of new and existing customers from days to minutes. With embedded signup, you own your WhatsApp Business Accounts (WABAs) and share access to them with Zoho desk. This allows you to use your WABAs and seamlessly integrate with other Facebook experiences, such as ads that click to WhatsApp. Additionally, the signup process is simplified by having all the steps in a single flow, from connecting your Facebook and WhatsApp business accounts to verifying the business phone number. You can learn more about this in the Onboarding Process section.

Yes, you no longer need to wait to complete the business verification process to start testing the API. Once signed up, you will have access to a trial experience during which you can send business-initiated messages to two phone numbers, and have up to ten customer-initiated conversations for the first 30 days. This trial is only valid for the first verified phone number for each WhatsApp Business Account.

How much should I pay?

Zoho Desk manages the billing and credit line for your WABAs. That said, there is the new Conversation-Based Pricing model announced by WhatsApp.

Business verification

During the unverified trial experience, you can only send business-initiated messages to two phone numbers, and have up to ten customer-initiated conversations for the first 30 days. After 30 days, you will no longer be able to send messages until you complete Business Verification and pass all WhatsApp checks.

In order to establish a fully-fledged instant messaging live conversation platform, you must get your Facebook Business Manager Account verified by providing all the necessary documents, including proof of legal entity and proof of access to the business. Only then will your expanded trial version be enabled, which allows a two-way conversation between you and a customer with 1500 customer-initiated messages. Please remember that a conversation is a 24-hour session of unlimited messaging with a given phone number.

WhatsApp channel statuses

Once you add a WhatsApp channel, its Edit page will indicate one of the following statuses based on your integration progress.

Hooray! Your Whatsapp Business Phone number is connected successfully. Your Facebook Business Manager account has been verified and enabled with the expanded trial version.
Whatsapp business account rejected! The documents that were submitted for validation have been rejected. Facebook rejected your Business account since it didn't meet the criteria they have determined. You must resubmit for verification after 35 days of the last submission.

How to edit the WhatsApp API business profile

Your WhatsApp Business Profile is important to your company’s growth. It acts as the digital storefront of your business, displaying key information that helps customers identify and trust your brand. Keeping it accurate and up to date can go a long way in establishing credibility and building strong customer relationships.

Updating your WhatsApp display name

When you change your WhatsApp display name in Meta’s WhatsApp Manager, Meta must review and approve the new name. After approval, your business phone number must be re-registered with WhatsApp to apply the updated display name.

Re-registration must be completed after Meta approves the new display name. Re-registering before approval does not apply the name change.

Applying the approved display name in Zoho Desk

Currently, re-registration requires assistance from the Zoho Desk support team. If Meta has approved your new display name but the previous name is still displayed, contact Zoho Desk support with the following details:

  • Your WhatsApp business phone number, including the country code.

  • Your previous display name and the newly approved display name.

  • A screenshot from WhatsApp Manager showing the approved name and any registration prompt.

The support team will coordinate the required re-registration and verify that the updated display name is reflected in Zoho Desk.

You do not need to repeat Embedded Signup to apply an approved display name change.

Access sandbox for testing

Zoho Desk offers businesses a WhatsApp Business sandbox, where you can send or receive prototype messages in a test environment before you go live, so you can analyze your API's functionalities. The WhatsApp sandbox helps you test numbers even before WhatsApp approves your business number and verifies your WABA, so you can get to work as soon as you're ready. This helps you to provide your customers an truly omni-channel support alongside understanding the apps best possible usage to maximize successful customer support interactions.
Alert
Effective October 1, 2026, WhatsApp (Meta) charges for service messages and for utility messages sent within an open 24-hour customer service window, which were free until then. Because of this pricing change, messaging through the WhatsApp sandbox is now restricted. If you try to send a message from the sandbox, you will see the error "You cannot message this user because sandbox messaging is restricted."



Frequently asked questions

Q1: What do I need to integrate WhatsApp with Zoho Desk?
You need a Facebook Business Manager account, a WhatsApp Business Account (WABA), and an eligible business phone number. The document also lists business verification as a prerequisite. You must have administrator privileges in Zoho Desk to configure the integration.
Q2: What is Embedded Signup?
Embedded Signup lets you connect your Facebook and WhatsApp Business accounts, create your business profile, and verify your phone number through a single onboarding flow. You retain ownership of your WABA and share access with Zoho Desk.
Q3: Where do I start the WhatsApp integration?
Go to Setup > Channels > Instant Messaging > WhatsApp, click Configure, and then click Integrate. Sign in to your Facebook account in the same browser before starting.
Q4: Can I use a number already registered with WhatsApp Messenger or the WhatsApp Business app?
For the standard WhatsApp Cloud API integration, you cannot use a number that is actively registered with WhatsApp Messenger or the WhatsApp Business app.
However, WhatsApp Co-Existence lets you connect a number already active in the WhatsApp Business app to Zoho Desk while continuing to use the app. Messages sent from Zoho Desk appear in the app, and messages sent from the app appear in the Zoho Desk inbox. This exception applies to the WhatsApp Business app, not WhatsApp Messenger.
If your number is already configured as a standard WhatsApp Cloud API channel, it cannot be used directly for Co-Existence. To switch:
  1. Remove the existing WhatsApp channel from Zoho Desk IM.
  2. Remove the number from the Meta Business console.
  3. Register the number in the WhatsApp Business app.
  4. Connect it to Zoho Desk as a WhatsApp Co-Existence channel through Embedded Signup.
Q5: How do I verify my WhatsApp Business phone number?
Choose Text Message or Voice Call, click Send Code, and enter the six-digit verification code received on your business phone number. Then click Verify.

Q8: What is the difference between deactivating and deleting a WhatsApp channel?
Deactivating a channel stops incoming and outgoing messages while preserving existing conversations. You can reactivate it later.
Deleting a channel preserves conversations as read-only, but agents can no longer respond to, transfer, or block those chats. The associated phone number becomes available to configure another channel.

The document lists these limits:
