Custom Url Link

Hello,

I am new at Zoho and this feature may be built in but i can not find it.

I am trying to create a url link in the contacts page that links to an external site with the contact id appended to the url. ${Contacts.Email} will work if ${Contacts.Id} is not available. I need to do this so i can create a custom key for that user to use our software.

I come from Salesforce and they have a built in custom button/link function which made this feature easy.

The only work around i have been able to figure out is by using my api key and searching for the contact from my external site first then selecting the user and inserting the code into zoho from that external page. I really don't want my people to have to go to another site just to generate license keys for our software when append feature should be available in the url field.

In short i want a link that comes up on every contact page that says http://www.somesite.com?id=.${Contacts.Id}

Does anyone know if this is possible?

Thank you very much.
