So I got the job to integrate Zoho CRM with a customer application. The documentation tells me to generate a "Self-Client" or how to generate an access token with user intervention, but the system should access the CRM API without this intervention and I am not able to generate a new Self-Client when the other should get invalid. Is it possible to access the API without these? Or is there a work around? I found only SDKs for PHP, Java and others, but not for ruby. Is there a ruby SDK planned?
