Mailchimp Transactional is a separate service from Mailchimp’s main marketing platform. It’s specifically designed for sending transactional emails, which are automated messages triggered by specific events or user actions.

Prerequisite:
To use Mailchimp Transactional Email with Wiresk, you must have a Mailchimp account, you can create one here.
For more information about the integration, refer to Mailchimp API endpoint documentation.

A screenshot of the group management page in the Wiresk platform. It shows a list of groups with their name, key, flow count, and flow execution status. There is a search bar and a button to create a new group.

The group system in Wiresk is a way to organize and manage your users and Flows.

When you start with Wiresk (Admin account), you are automatically assigned to the default group. This default group can be renamed.

for users with Pro plan or higher, you can:

  • Assign users to specific Flows: Control who has access to and can edit different Flows.
  • Organize Flows: Group related Flows together for better management and visibility.
  • Manage permissions: Set permissions for different groups, determining who can create, edit, and view Flows.
  • Collaborate effectively: Facilitate collaboration among team members by assigning them to appropriate groups.
For more details about Group and Users, refer to Group system.

A connection to your Mailchimp is needed so we can sync it with our platform.

There are two ways to connect your app to Wiresk:

  • In “My apps” section, where you can manage your connections (select or create your group first to get access to this section, refer to the Group system ).
  • While building your Flow, you can easily establish a connection to your app directly within the Flow builder. This can be done during the setup of either a Trigger or a Method.

In this documentation, we will explain how to create a connection in “My apps” section, it is essentially the same as when creating it on-the-go.

On the left panel of Wiresk user interface, go to “My apps” and click on the (+) button. 

Search “Mailchimp” in the search field or scroll down the list of apps and choose the Mailchimp icon.

Give a name to your connection, here we will name it “Mailchimp Transactional”.

Select Mailchimp Transactional connection tab

Enter the Mailchimp Transactional API Key:

Then, click on “Create app” button, voila! You have connected Mailchimp Transactional to Wiresk.

You can now use this connection in your Flows.


After linking Mailchimp Transactional to Wiresk, you can start creating your Flows.

Select your Group, then on the Flow management screen click on “Create Flow”.

On the new screen, select your specific Trigger then configure it (refer to Trigger settings below).

As mentioned in “How to connect your app to Wiresk” above, during your Trigger settings, you can create a new connection to your apps at this stage.

An HTTP Trigger allows you to manually activate your Flows.

  • One-time tasks: For tasks that only need to be performed once, like sending a specific notification or updating a database record.
  • Ad-hoc actions: For actions that need to be triggered on demand, without relying on scheduled events or data changes.
  • Testing and debugging: For testing and debugging Flows without relying on external events or conditions.

Click on the red plus button (+) again to add a Trigger for testing your Flow, then click on the button “HTTP Trigger”.

Write a description and select your API key or create a new one.

Click on save.

Now you can use your HTTP Trigger to Manually run your Flow.

The Method will perform a specific task on a particular app or service you’ve connected to Wiresk like get info or send emails.

You can add at least 1 or multiple Methods for complex Flows (a maximum of 255 Methods).

On the Flow builder screen, click on the plus button (+) next to the Trigger icon.

To add Tools in your Flow, Follow the same step as adding the Methods. On the Flow builder screen, click on the plus button (+) then just click on the “Tool” tab and select the Tool that you want to add.


What will start your automation…

Keep in mind that, we have combined Mailchimp Transactional Triggers (formerly Mandrill) with Mailchimp Triggers.
You can distinguish between different Trigger types by their color. Triggers associated with Mailchimp Transactional Email will have a yellow Mailchimp logo. To use Mailchimp Triggers (Black on grey background logo), you must first establish a connection. See Mailchimp documentation here.
Depending on your Flow scenario, you can set up multiple Triggers. However, only one Trigger can be active at a time.

Setting up the recurrence rule or scheduler of your Trigger (if the Trigger is not a Webhook):

  • Regular intervals will monitor your Trigger by intervals in minute
  • Daily recurrence will monitor your Trigger by day and hour
  • Monthly recurrence will monitor your Trigger every month on a defined date and hour
  • Yearly recurrence will monitor your Trigger on a specific date and hour every year
  • Specific dates will start your Trigger on specific dates

After setting up the Trigger parameters (refer to how to define your parameters in the steps below), click on “Get sample”.

The “Get sample” allows you to extract a subset of data for validation. The data will be used to MAP your Method parameters according to your Flow. Refer to FIELD MAPPING documentation.


These Triggers will start your Flow automatically at a specific time or intervals instead of being triggered by events like Webhooks.
