Vertical Solutions is hosted at multiple data centers. Therefore, the API domain URL varies for each data center. This makes integration simpler and avoids conflicts between browser extensions and the user's current session.
The various domains and their respective API domain URLs are:
US: https://{your-solution-name}.zohoplatform.com
EU: https://{your-solution-name}.zohoplatform.eu
When you made an Authorization Request using the below authorization URL,
https://{Your_Solution_Name}.zohoplatform.com/clientoauth/v2/{Portal_ID}/auth?scope=ZohoCRM.modules.ALL,ZohoCRM.settings.ALL&client_id={client_id}&response_type=code&access_type={"offline"or"online"}&redirect_uri={redirecturi}
the response to the request was:
{redirect_url}?code={unique_code}
The, the domain-specific URL to fetch all CRM Leads is
EU domain: "https://zylkercorp.zohoplatform.eu/crm/v4/Leads"
US domain: "https://zylkercorp.zohoplatform.com/crm/v4/Leads"
You must make the authorization request from https://{your-solution-name}.zohoplatform.com for the EU domain. After the request is successful, the system automatically redirects you to your domain.
