I'm working with a client to integrate ZC with an api-enabled service. When a user registers with ZOHO, I also need to POST the user's contact data to the api. The api requires a checksum value in the POST request. The checksum is a combination of my admin name, api account name, and user email. However, it's created using the MD5 command. In PHP this is:
$test = "buzzap123256joe@gmail.com" ;
echo md5($test);
Gives a checksum: 9cc309fef02d2dc5e49c612838dbe20b
