How to integrate MailerLite in automation workflow?

3 simple steps to make your MailerLite connected with other apps in automation workflows on WEXTL. Up to 10 minutes integration set up.

STEP 1

Select MailerLite in workflow

Pick MailerLite app in the workflow builder [4] - just one click to select the app.

STEP 2

Connect MailerLite

When prompted, authorize access to MailerLite in WEXTL once. MailerLite credentials are encrypted and never shared with WEXTL. Authorization will be reused in any future API calls [3].

WEXTL wants to integrate with your MailerLite account. Approve?

STEP 3

Build a workflow

Build your workflow with MailerLite yourself or with WEXTL® AI Builder. Connect MailerLite to any available integrations [5], or use HTTP node to go beyond them.

MailerLite

How MailerLite connects and integrates with WEXTL

Save and approve your credentials once — WEXTL® stores authorization information encrypted and reuses the authentication whenever MailerLite app is called in workflows. That allows your communication automations to run without your attention, per defined schedule [7]. Explore documentation [6] for a detailed list of fields that MailerLite supports.

Full MailerLite API documentation

The following table illustrates what fields MailerLite integration require during authorization flow inside our workflow builder [4].

Demonstration of MailerLite connection step inside WEXTL Workflow Builder [4].

Field	Type	Help
API TokenRequired	password	To get your API token: log in to MailerLite, go to Integrations (or click your profile > Integrations), select the API and click 'Generate new token', name it, then copy the token and paste it here. It is shown only once, so copy it immediately. Sent as a Bearer token.

Connect MailerLite to popular apps on WEXTL

Enter a name of the other app you want to sync with MailerLite below. Click on selected app to explore integration options with MailerLite. If the app you search for is not available in WEXTL yet, you can use HTTP node [10] instead to integrate it directly.

Example automation with MailerLite integration

Select Watch Form Subscribers trigger from MailerLite - this will be a starting point in your automation. Whenever event happens in MailerLite, workflow will start [7] from Watch Form Subscribers node.

Search for Create/Upsert Subscriber, connect it as the next step of integration sequence. You can use filters between Watch Form Subscribers and Create/Upsert Subscriber, so only important data pass from Watch Form Subscribers to the next step. WEXTL gives you full control over the process of MailerLite automation. All parts of workflow are visible on the canvas [4].

MailerLite on WEXTL has 106 modules for combining communication automations. Explore MailerLite documentation for more.

Frequently asked questions

Common questions about automating MailerLite in your workflows.

MailerLite has 15 triggers, including "Watch Automations", "Watch Campaigns", and "Watch Categories", and more. Triggers are start points of the workflow, and automations may start from them.

Integration has 91 actions, including "Fetch Cart", "Fetch Cart Item", and "Fetch Category", and more. Refer to our MailerLite Documentation for detailed inputs and outputs.

No. Most automations are built visually on the canvas by picking triggers, actions, and mapping fields. You can add custom JavaScript with Functions when advanced logic is needed — but our customers do that in rare cases [4].

Yes. Connections are authenticated per account, credentials are encrypted at rest, and you can enforce approvals and team-level access controls on any automation.

The MailerLite integration on WEXTL runs directly on its vendor public API — every field name, authentication method, and rate limit is controlled by MailerLite official API and covered in documentation [3]. WEXTL handles the request signing and pagination for you.

Absolutely. Where MailerLite provides native webhooks, you can use instant triggers to eliminate polling delay. For custom webhooks, WEXTL offers Custom Webhook node, so you can start automation whenever MailerLite or any other service sends event to webhook URL.

WEXTL is an AI-first visual canvas. The platform allows you to describe automation in plain text — and AI will wire nodes for MailerLite inside the workflow builder [4]. You can also use built-in workflow nodes (AI Agent, Human in the Loop, Condition, Aggregate Results) in pair with MailerLite modules to craft complex integration flows with branches, filtering, and conditional logic. There are absolutely no limits of what you can build.
