In this document we want to share with you a clear guideline to create a message using your WhatsApp API from your CRM.

  • The CRM is the core of your business.
  • You can create segments and launch a campaign.
  • Obviously, email is dead, phone calls are dead. You can use WhatsApp to notify your users with a message about their status.
  • WhatsApp is a very personal channel and you need to be very careful with the content and messages you are going to send. So please select the users and message with care.

Why you should use it

  • Why you should use it: Sending a whatsapp can be difficult, so we’ve simplified the api to to make hassle free

How to use it

  • How to test it: You can test it by having you crm send a whatsapp to a predefined number like your own



HEADER Authorization: xxxxx_your_key_xxxxxx


   “to”: 34622814642,

   “template”: “your_360_template_id”,

   “apikey”: “your_360_apikey”,

   “namespace”: “your_360_namespace_same_for_all_templates”,

   “language”: “en”,

   “apikeyManyContacts”: “your_many_contacts_apikey”,

   “manyContactsName”: “The many contacts inbox tag you wish to use”,

   “params”: [




   “button_params”: {

       “type”: “url”,

       “url”: “xxx.pdf”



Params: are the template variables like the same of your client or perhaps the order ID.

Button_params: this property is optional and only used if your template has a button


200 = OK

Otherwise the corresponding error code is sent with any available information

Do I need to buy a whatsapp API or just having a whatsapp account is enough?

WhatsApp API is only required for some automated services like campaigns and when you use our PrestaShop, woo-commerce, or Magento modules.

Can we use this for whatsapp email campagins?

You can add a link to your agent in an email or you can use “campaigns” to send outbound messages to your users. For that, you need WhatsApp API and there are some restrictions.

Number verification and API?

Verifying your number and having the API is a single step. Many people ask us for verification as if it were on Instagram or Twitter. There is no JUST verification.

  • It is done against Facebook
  • You have to be a registered company
  • It has a cost
  • You pay per conversation

What I need before starting the verification?

To make sure that we do the process as fast and easy as possible, there are some things we need to take care of before starting.

  • Make sure you need it
  • Number without a WhatsApp account
  • Facebook business ID connected on Facebook manager
  • Bussines details on official document
  • Prove of owning the phone number ( Bill for example)

Can I use my current number?

No. We recommend using a brand new telephone number or a number that never before had WhatsApp.

Verification needs to be done with a number that does not have WhatsApp, Facebook rules.

Take the opportunity to register a number just for that. It can be fixed or mobile.

Can I use WhatsApp APP?

No, The API is used with applications such as:


  • Trengo
  • Rocket Chat 


  • Zapier
  • Any type of code

Can I send mass messages?

But the focus of WhatsApp is to use it as a notification tool or as a reminder. Commercial spam is not welcome.

✅ Reminders
✅ Recover carts
✅ Notifications based on CRM status
✅ Recurring shipments (every week do this)

Costs, deadlines?

  • Verification: $200 a year. 2 weeks.
  • Services: Depends on each provider
  • Inbox: Standard price $15 per agent / month
  • Conversation cost: 0.04 push conversation (variable)

Use cases for necessity

Inbound + Outbound

Inbound –> We attract clients with campaigns where the entry route is WhatsApp

Outbound –> I have a client portfolio and I want to activate it

When visitors want to chat , do they have to put their phone/WhatsApp number to start the conversation?

When you create a form you can add a phone field, but this is completely optional. You do not need to add this field mandatory.
