Question from Reddit user:
Y’all before I waste my entire Saturday, I’d love to know if there’s a creative way to generate email campaigns via an API solution so I can use MAke.com/ zapier to send out an email.
Thanks in advance – I appreciate you guys!
Answer from Nabil:
The short answer is:
Absolutely yes, you can use Make.com or Zapier to trigger emails and campaigns in HighLevel via the HighLevel API.
There are two main ways to do this: either call the API endpoint for sending a one-off email, or more effectively, you can call the API endpoint that adds a contact to a specific pre-built Workflow or Campaign in HighLevel, letting HighLevel handle the sequence of emails.
The HighLevel API has specific endpoints like POST /v1/campaigns/{campaignId}/actions/addContact or POST /v1/emails/send that can be targeted using the HTTP module in Make.com or the Webhooks by Zapier action.
The long answer is:
The most creative and powerful way to do this is by leveraging HighLevel’s native Workflows in combination with an API call from your automation tool.
Instead of trying to build and manage complex email logic directly inside Make.com or Zapier, which is costly and difficult to maintain as your business grows, you simply tell HighLevel to start its own pre-defined automation.
In your HighLevel account, you build a Workflow that contains your entire email campaign – a welcome email, a wait step, a follow-up email, and so on.
You then configure the trigger for that workflow to be a specific event or contact tag.
From Make.com or Zapier, you use the HTTP module or Webhooks action to call the HighLevel API with a POST request that either creates a contact and immediately tags them, which then triggers the Workflow, or directly uses the addContact endpoint to insert an existing contact into that Campaign.
This method is incredibly robust because HighLevel manages the timing, deliverability, and tracking, freeing up your automation platform for other tasks.
A key reason this is an excellent and potentially cheap solution is that you can centralize your data processing using server-side tagging tools like Google Tag Manager paired with a hosting solution like Stape or Google Cloud Platform.
When a lead comes in from a form or an external source, instead of going straight to the automation platform, you first send the data to a server container, which is often free or very low-cost.
This server acts as a clean data layer, enriching or cleaning the data, then sending a final, clean payload to your Make.com or Zapier webhook, which in turn calls the HighLevel API.
This allows you to control all your data logic and third-party API calls from one centralized, stable server environment, reducing errors, improving data quality, and cutting down on the number of complex steps you need to pay for in high-volume, multi-step Zaps or Make scenarios.
