Keeping up-to-date contacts in both Zoho CRM and Google Contacts is now made easy with the Contacts Synchronization feature. It helps you to configure one-way or two-way sync schedules that will automatically sync contact details. Also, you can specify the list to which the contacts should be transferred and map fields as required. Please note that if you delete the sync configurations and again synchronize the contacts, then duplicate records will not be created based on the email address that is mapped.

Step 1 

1. Choose the module to sync with Google. Three modules will be listed in the drop-down : Contacts, Leads and Vendors.
   
2. Choose one of the Sync Options.
   
1. 2 Way Sync
   
2. 1-Way: Zoho CRM Contacts to Google Contacts
   
3. 1-Way: Google Contacts to Zoho CRM Contacts
   
3. Select one of the following option when there is a conflict in contacts in both the places.
   
1. Zoho CRM contact will overwrite the Google contact
   
2. Google contact will overwrite the Zoho CRM contact
   
4. Choose the synchronization Frequency from the drop-down list.
   
5. Click Next.
   

Step 2 

1. Map the fields in Google and Zoho CRM.
   
2. Click the Map More Fields link, to add more fields and map them.
   
3. At the bottom, under Select additional fields to sync with Google, you can select custom fields from the drop-down to sync with Google.
   
4. Click Next.
   

Step 3 

1. Enter the default value for the Last name field and all mandatory fields. Click Add Fields to add default values for optional fields. Select the field and enter the value.
   
2. Click Save.
   

Note : We will now allow partially-active syncs because of Google's limitations on the number of records that can be synced. Since Google only provides 25000 for any sync process, once this limit is reached, we will stop pushing records from Zoho CRM to Google. 

Note:

1. The synchronization of contacts from Zoho CRM to Google and vice versa will take a while to complete based on the number of contacts. We request you to wait for a few minutes and then check if the contacts have been synchronized.
   
2. Please note that if you delete the sync configurations and again synchronize the contacts, then duplicate records will not be created based on the email address that is mapped.
   
3. Check the Last Sync Time in the Contacts Synchronization page to see if the sync was performed.
   
4. Based on the roles and access privileges, the contacts will be synchronized.
   
5. First time you can synchronize maximum 10,000 contacts. For the consecutive syncs, maximum 500 contacts will be synchronized.
   
6. The criteria to search duplicate records are based on the Email field value (primary email field in contacts) in Zoho CRM and Email (Work) field value in Google Contacts.

2. In Zoho CRM, go to Marketplace > Google > Contacts.
