Octopods now brings powerful messaging capabilities directly to your HubSpot workflows. Send WhatsApp Message Templates and SMS messages programmatically to your contacts, seamlessly integrating multichannel messaging into your existing HubSpot automation.


WhatsApp Message Templates

Templates are reusable WhatsApp messages that you can send to your contacts, with customizable variables that adapt to each recipient. These are useful for notifications, follow-ups, and customer service communications.

Once the 24-hour customer service window has expired, Message Templates are the only way you'll be able to reestablish contact with your customer. Click here for more information on the customer service window.

What you can do:

  • Send pre-approved WhatsApp message templates to your HubSpot contacts

  • Personalize messages with dynamic variables from HubSpot contact properties

  • Trigger WhatsApp messages based on HubSpot workflows and automation

  • Track message delivery status and sync conversations back to HubSpot

  • Create new HubSpot contacts when messaging new WhatsApp users

  • Assign conversations to specific HubSpot team members


SMS Messaging

Send direct SMS messages to your contacts for time-sensitive communications, alerts, and simple notifications that don't require WhatsApp's template approval process.

What you can do:

  • Send instant SMS messages to any phone number

  • Integrate SMS into your HubSpot workflows and sequences

  • Track delivery status and engagement in HubSpot

  • Create conversations in HubSpot from SMS interactions

  • Build custom SMS campaigns triggered by contact behavior

  • Reach contacts who may not use WhatsApp


How Does It Work?

Once your WhatsApp Business API account or SMS channel is connected to HubSpot through Octopods, we generate an API Key that can be used to access our messaging APIs.

You can retrieve your API Key directly from your Octopods dashboard, as follows:

Step 1: Select your channel

Navigate to your Octopods dashboard and select the WhatsApp Business account or SMS channel you want to integrate with HubSpot.

Step 2: You'll find the API key on the account screen

Your unique API key will be displayed on the account settings page. Keep this key secure as it provides access to send messages on behalf of your connected channel.
