You need to generate the API key in MailBluster if you want to integrate your app/website with MailBluster.

To generate the API key, you need to go to your Brand > Settings > API Keys then click Create new.

Type the API key name and then click Create API key

Once the API key is generated, copy the Key value and use it with your app/website.

The default rate limit for MailBluster Developer API is 10 requests/second and 100 requests/minute.

Lead hash is the md5 encrypted value of lead’s email. To obtain the MD5 hash value of your lead’s email, you can use various MD5 generator tools available online. One such tool is located at MD5 Hash Generator. Simply input the email address of your lead into the tool, and it will generate the corresponding MD5 hash value, which is known as {lead_hash}

Then, you will need to send a GET request to read the specific lead to this API endpoint:  https://api.mailbluster.com/api/leads/{lead_hash}

Check out this guide: https://app.mailbluster.com/api-doc/leads/read.

Please note: Some technical knowledge is required to implement this technique.

You can find information on the MailBluster Developer API by visiting the MailBluster documentation site. Navigate to the Developer API section under Resources > API Doc, where you’ll find detailed guides, API endpoints, usage examples, and other resources needed for integration. This documentation provides all the necessary information for developers to effectively use the MailBluster API, enabling management of leads, fields, products, and e-commerce activities from outside your MailBluster account. The API’s simple and intuitive design allows you to manage four key aspects of the platform: Leads, Fields, Products, and Orders.

A CORS error occurs when you make a request from an HTML form submission or an AJAX call. This happens because anyone can intercept the request and view the secret API key, which is why CORS restrictions exist.

If you are getting CORS errors, it means you are calling the MailBluster developer API directly from your frontend. Instead, you need to call the MailBluster developer API from your backend.

To resolve this, send the request from your backend using languages like PHP, Node.js, Python, Ruby, etc. You can test this with Postman or a similar API testing tool to ensure it works as expected.

Calling the MailBluster developer API from the frontend will not work due to CORS errors and the associated security risks. Exposing your API key publicly can lead to major security issues.

Always make API calls from your backend to keep your API key secure. This approach will prevent CORS errors and protect your API key from being exposed.

You cannot update multiple leads using MailBluster Developer API.
Only single lead can be added at a time. Same goes for update and delete while using the Developer API.

If you want to import more than one lead at a time, then you need to use the MailBluster main app.

Here is the API documentation for your assistance: https://app.mailbluster.com/api-doc.

MailBluster Developer API is not designed for sending and receiving emails, such as bulk emailing. However, it allows you to manage your leads, products, and e-commerce activities from outside your MailBluster account.

The API is specifically designed to control Leads, Fields, Products, and Orders. In simple terms, the Developer API is intended for collecting leads from the client’s website and managing related data. It is not capable of sending emails.

For further details on MailBluster Developer API, please visit: MailBluster API Documentation.

MailBluster by default, sends email at 90% rate. If a user requests to lower the send rate through support, then our Tech team can reduce it to 50%.

Pabbly is an integration tool that allows users to automate workflows between different applications without any coding. It helps connect apps like Google Sheets, MailBluster, and many others to automate tasks. Primarily, Pabbly requires 2 steps to initiate the automation process: Trigger and Action. Let’s integrate MailBluster with Pabbly to understand how it works.

First, click on Create Workflow.

Enter the Workflow Name.

Select Google Sheets from Choose App.

Then select New or Updated Spreadsheet Row from Trigger Event.

Now go to Google Sheets > Extensions > Add-ons > Get add-ons.

Click Save & Send Test Request. This will save the values you entered above and send the data to the selected app for processing. A response will be received once processing is complete.

Now, go to MailBluster, and in the Leads section, you will see that the email address has been added to Leads.

Go to your Google Sheets and add a new lead to test if it is automatically added to the MailBluster Leads.

As you can see, the lead above has been successfully added to the Leads section in MailBluster automatically.

As you can see, we have focused on connecting Google Sheets with MailBluster to streamline the automation process using Pabbly. Similarly, you can achieve this with the following options.

Make (formerly Integromat) is a visual, no-code automation platform that allows users to connect and automate tasks across various apps and services. It enables users to create workflows, known as scenarios, that streamline processes and remove repetitive tasks without requiring any programming skills.

Make operates with a system of triggers and actions to execute workflows from start to finish. A trigger is an event that initiates the workflow, telling Make when to begin running each step in the automation. Following a trigger, actions are the tasks Make carries out in response. By combining triggers and actions, ‘Make’ lets users build flexible, multi-step workflows that connect tasks across different applications seamlessly.

As you can see, we are going to demonstrate on how to connect MailBluster with ‘Make’ using Google Sheets. Similarly, you can accomplish this with the follow options as well.

MailBluster doesn’t provide direct sync support for the Shopify website yet.

But you can integrate MailBluster into Shopify using these two ways:

1. Using MailBluster developer API
You need to customize Shopify to send the lead information to MailBluster using the developer API when a customer signs up to your store. You need to have the technical knowledge to do this or need help from a software developer.

2. Using Make (formerly Integromat).
You need to create a scenario on Make to connect Shopify with MailBluster.

For both Shopify and MailBluster, you need to create a new connection on Make that is not shown in the video. For MailBluster, you just need to create a new API key from Settings > API Keys page from MailBluster and provide the Key in Make.

You can use MailBluster with OpenCart using a 3rd party tool called Make (formerly known as Integromat). The following link will help you with connectivity and integration using MailBluster: https://www.make.com/en/integrations/mailbluster.
Also, you can check out this detailed guide and how to use Make with MailBluster.

We also have a video tutorial on this which shows how to import Leads from Google Sheet to MailBluster using Make:
