Zoho Creator's v2 APIs are now live
Improvements that v2 brings
- OAuth-based authentication, which is more secure than the authtokens
- Support for the PATCH and DELETE methods
- Better structuring of the API request: form data is to be added to the request’s body in the JSON format
- Better error handling resulting from a more insightful set of error codes and messages
- Better performance in comparison to the current version (v1)
- No keyword restrictions

Documentation
The link name reference page is the same for v2 APIs as well
To ensure that you use the right domain in your API requests, the term base_url has been used in the documentation and linked to the Creator account's base URL
Other things to know
- v2 APIs accept only JSON inputs and return the response in the JSON format
- The request rate is the same for v2 APIs as well — 50 requests per minute per API endpoint per IP address
- Unlike v1, there's no limit to the response size in v2. However, v2 APIs can process a maximum of 200 records per request.
- The Get Record - Detail View API will not fetch the records displayed in the related data blocks (if any)
- For Creator 5 accounts, the view records API (v1) fetches data from the fields that are displayed in the quick view AND detail view.

To migrate your v1 implementations to v2, in short:
- Revisit the reasons for which you used our v1 APIs.
- Identify the scopes you'll require for those operations.
- Register the client applications that are to use the Creator APIs, by creating client credentials for them.
- Generate access and refresh tokens.
- Set up connections from your applications to Zoho Creator using the corresponding client credentials, scopes, and access tokens.
