Populate form with CRM Contact data?

Populate form with CRM Contact data?

Greetings,

I'm trying to populate this form (attached) with CRM Contact data. I am a Zoho One customer (paid) which means I have the Enterprise editions, so it's not an account limitation.

I'm working strictly with deluge scripts.

I can default the Email field like this:
input.Email = zoho.loginuserid;

My goal is to get the first and last names and default the Zoho_CRM field from the corresponding CRM contact record using this script:
crmContactRecord = zoho.crm.searchrecordsbypdc("Contacts","email",zoho.loginuserid);

I've tried parsing the response, but either get null or the dreaded {"4834":"Invalid Ticket Id"}.

From all the other threads I've read, they talk about auth tokens. Since I'm working with deluge, I fail to see the need for auth tokens.

Can anyone help me with this?

Thanks!
