How can we help?

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.

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.

You can configure the pop-up’s timing and choose its position—left, center, or right—at the beginning, middle, or bottom of the page.

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.
