MessagingConnect with an API key

WhatsApp Cloud API (Meta) voice AI integration

The WhatsApp Cloud API (Meta) integration connects your AI voice and chat agents to WhatsApp Cloud API (Meta), so they can read whatsapp messages on a live call. It's a messaging connector that runs as a tool the agent calls mid-conversation — you connect with an api key, attach it to an agent, and it acts in real time without a human in the loop.

What your agent can do with WhatsApp Cloud API (Meta)

Read WhatsApp messagesread whatsapp

Read the most recent WhatsApp messages exchanged with a contact — each with its sender and timestamp. Use during a call to recall what the user has sent you over WhatsApp.

Inputs

FieldTypeDescription
limitintegerHow many recent messages to return (default 10, max 50).
tostringContact phone number with country code, e.g. +919876543210. Omit to use the current caller.
List WhatsApp templateslist_templates whatsapp

List approved WhatsApp message templates and their variables.

Send WhatsApp templatesend_template whatsapp

Send an approved WhatsApp template message (works outside the 24-hour window). Fill the template variables in order.

Inputs

FieldTypeDescription
button_copy_codestringOnly for a template with a COPY_CODE (offer / coupon) button — this is the code the recipient taps to copy, e.g. SAVE20. Leave empty for a URL button, a quick-reply button, or no buttons.
button_copy_code_indexstringWhich button the code belongs to, counting from 0, when the template has more than one. Leave empty if the copy-code button is the first one.
button_indexstringLeave empty unless the template has more than one button. WhatsApp numbers buttons from 0 in the order they appear on the template, and the value above fills the one you name here — naming the wrong one sends a working link on the wrong button.
button_url_suffixstringOnly for a template whose URL button ends in a placeholder — this is the part appended to the button's URL. Leave empty for a static button, a quick-reply button, or no buttons.
header_mediastringPublic URL of the file shown in the template header. Only for templates whose header is an IMAGE, VIDEO or DOCUMENT. WhatsApp fetches it at send time, so it must be reachable without a login.
header_media_typestringUsually left empty — it is worked out from the URL. Set it when the link has no file extension (a signed CDN URL), because WhatsApp needs the right type or it rejects the send.
header_textstringOnly for a template whose header is TEXT and contains a placeholder — e.g. a header reading "Hi {{1}}". This is the value that fills it. Leave empty for a media header, a static header, or no header.
languagestringLanguage code, e.g. en or en_US
template*stringApproved template name
to*stringRecipient phone with country code, e.g. +919876543210
variablesarrayBody variable values in order ({{1}},{{2}},…)
Send WhatsApp messageSend WhatsApp

Send a WhatsApp message to a phone number. Use for confirmations, payment links, addresses, or any details the caller should have in writing.

Inputs

FieldTypeDescription
message*stringThe exact message text to send
to*stringRecipient phone number with country code, e.g. +919876543210

What you'll need to connect WhatsApp Cloud API (Meta)

Connect with an API key. In Telenow, open Integrations → WhatsApp Cloud API (Meta) and provide:

  • Permanent access token
  • Phone number ID
  • WhatsApp Business Account ID — From Meta Business Manager → WhatsApp Accounts. Enables fetching + sending message templates.
  • Meta App ID (optional) — From developers.facebook.com → your app → Settings → Basic. Only needed to create templates with an image, video or document header — those upload their sample file to the app that owns the number.
