Connect your AiSensy account to Bolna once, then send approved WhatsApp templates from any step of a workflow — no separate WhatsApp setup, no code.

​
What is AiSensy?

AiSensy is a WhatsApp Business API platform. It sits between your business and Meta’s official WhatsApp Business API — handling business verification, the approved sender number, template management, and message delivery, so you don’t have to build against Meta’s API yourself. The pieces of AiSensy that matter for this integration:
  • Project — your AiSensy workspace. Each project has its own WhatsApp Business number and its own API key.
  • Template — a pre-written message format that Meta reviews and approves. On WhatsApp, business-initiated messages must use an approved template.
  • Campaign — a launched instance of a template. This is what you actually select inside Bolna.

​
How AiSensy is integrated into Bolna

AiSensy is integrated directly into Bolna workflows. You paste your AiSensy project API key and project ID into Bolna once for authentication, and Bolna pulls in the list of WhatsApp campaigns running under that project. You pick a campaign, drop it into a workflow as an aisensy_whatsapp node, and Bolna sends that template on your behalf when the workflow reaches that step. That means a single workflow can mix voice and WhatsApp — for example, calling a lead, extracting how the conversation went, branching on the result, and following up hot leads on WhatsApp while the cold ones just end.

How to send a WhatsApp message in a Bolna workflow

1

Authenticate with your AiSensy project API key

  1. In AiSensy, open the project you want to send from.
  2. Go to Developer → Project API Keys.

  1. Copy the project API key.
  2. In Bolna, open your workflow, add the AiSensy WhatsApp node, and paste the key and project ID, then click Link AiSensy account.

The API key is scoped to one AiSensy project. If you run multiple projects (different numbers or brands), use the key for the project whose number should appear as the sender.
2

Select your campaign and send a test message

Once the key is accepted, Bolna fetches every campaign running under that project and shows them as a list.

Selecting an AiSensy campaign in the node inspector

  1. Select the campaign you want to use.
  2. Fill in any template variables (name, order ID, date — whatever your template uses). You can also use workflow fields as message variables.
  3. Send a test message to fire it to your own number and confirm the sender, wording, and variables all look right.
Always send a test before publishing. It’s the fastest way to catch a wrong variable order or a template that reads oddly once the placeholders are filled in.

Don’t have a campaign yet? Create one in AiSensy

A campaign needs an approved template first. Templates are reviewed by Meta, so budget time for this — approval is usually quick but not instant.

​
Create the WhatsApp template

1

Open Template Messages

  1. Log in to the AiSensy project the campaign should live under.
  2. From the left nav, select Manage (the gear icon), then Template Message.

Click Create Template in the top right, build your WhatsApp template following the on-screen instructions, then submit it for Meta review.Your submitted template appears under the All tab in the same section, with its current status.

Pick it up in Bolna

Head back to Bolna and refresh the campaign list — the new campaign is now selectable from the AiSensy WhatsApp node.

​
For developers: the aisensy_whatsapp node

If you’re building workflows through the Bolna API rather than the dashboard, the node type is aisensy_whatsapp. Its config fields (template_name, language, recipient, variables, campaign_name) and a full JSON example are documented in Workflow Nodes — including a note that the node is fire-and-forget for now, so there’s no delivery status to branch on yet.
