Hi,

Our web developer has asked if I can set up API access into Zoho CRM, so he can run GET requests against the contacts.

I've found the help document here: https://www.zoho.com/crm/developer/docs/api/get-records.html

Which gives me the API Get URL and the header, but I can't figure out how to create the API Authentication token.

I've gone to https://api-console.zoho.com.au/ and logged in with a CRM account.  I've set up (I believe) the API for access.  

My API Authentication configuration:

 - Server-based Application

 - Name: CRMAPILink

 - HomePage URL: Just our default business website

 - Authorised Redirect URIs:  Just our default business website

When I use postman to try to GET from https://www.zohoapis.com/crm/v2/Contacts and add an Authorization header with 1000.{ClientID}.{ClientSecret} I just get an authentication failed message.

I'm not sure if my Authorization header is incorrect, or if the API key creation was incorrect.  Could someone pleasae shed some light?

Thanks 

Luke
