If you’re using MailBluster and need to access individual lead data, the first step is to obtain the lead hash. A lead hash is the MD5 encrypted value of your lead’s email address, and it’s required for making secure API requests. To obtain the lead hash, you can use any trusted MD5 generator tool available online. For example, visit MD5 Hash Generator, input the email address of your lead, and the tool will generate the corresponding MD5 hash—this becomes your {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}
Details can be found regarding API from the following link: https://app.mailbluster.com/api-doc/leads/read.
Please note: Some technical knowledge is required to implement this technique.
