Recently started getting General Error 6500 in Zoho Projects API

We have a program that loops through a list of a few of our projects and fetches the time logs.
This was working for a few months, but about a day or two ago, we noticed that the time entries are no longer being returned. When I run our script manually, I see all the API calls are returning a General Error 6500.

I thought this could be due to the API call limit so I tried with a newly-generated auth token and it worked at first, but when I tried again I see the errors. Strangely it sometimes works for a few calls and then continues returning errors.

I've already done everything I can think of to minimize the number of API calls. Is there something else I can do to resolve this?

    • Announcing the Zoho Projects API

      Today we're excited to announce the API for Zoho Projects where any developer can extend the project management and collaboration capabilities through our APIs and can build their own customized applications for their business needs. We've tried to make the API follow the REST (Representational State Transfer) principles and generate a XML/ JSON object which allows you to access / read / write Zoho Projects data from third-party systems like Google/Yahoo gadgets, web sites, billing & invoicing systems,
    • Have you moved to REST API?

      Dear API Users, The Documentation of our Rest API is available here . All future development will be done to this version. We are deprecating the older API today. Its documentation will no longer be available and we will also be stopping the calls to this API soon. Thanks, Prasanna
