WhatsApp providers

Connecting Twilio, Meta Cloud API, or a custom webhook as your WhatsApp provider.

EzFlow supports multiple WhatsApp providers so you can use the account you already have. Each provider connection is stored as an encrypted MessagingIntegration record. The SEND_WHATSAPP node references a connection by its ID.

Supported providers

Twilio

Use your Twilio WhatsApp-enabled number to send messages.

Credential	What it is
Account SID	Your Twilio account identifier
Auth Token	Your Twilio authentication token
From number	The WhatsApp-enabled phone number in E.164 format
Messaging Service SID	Optional — use a messaging service instead of a direct number

Meta Cloud API

Use Meta's official WhatsApp Business Cloud API directly.

Credential	What it is
Access Token	A permanent or long-lived system user token
Phone Number ID	The ID of the WhatsApp phone number in Meta Business Manager
WABA ID	Your WhatsApp Business Account ID
App Secret	Used to verify incoming webhook signatures
Verify Token	A secret string you set when registering the webhook in Meta

Webhook

Send via any provider that accepts an outbound HTTP call. EzFlow posts a request using the template you define.

Credential	What it is
URL	The endpoint that receives the outbound message request
Method	HTTP verb (`POST`, `PUT`, etc.)
Headers	Optional key-value headers (e.g. `Authorization`)
Auth Token	Optional bearer token appended to the `Authorization` header
Body template	JSON body template for the outbound payload
Status URL	Optional URL for delivery-status callbacks

Adding a WhatsApp provider

Go to Settings → Connections (or the Integrations page).
Click Add WhatsApp integration.
Choose a provider, fill in the credentials, and save.

EzFlow encrypts the credentials at rest. You can create multiple connections — for example, one per phone number — and select the right one in each SEND_WHATSAPP node.

SEND_WHATSAPP — the node that uses this connection to send messages
Integrations — general credential storage used by other nodes
