All API calls give a 404


We recently started to get errors like 'error not found in insightly' for API calls that used to work fine.

So I thought to run a few tests in bash, for instance:


curl -v -X GET \
  -H 'Content-Type: application/json' \
  -H 'Authorization: Basic MY_AUTH_HEADER' \$1


where $1 would be a an email address present in our insightly setup.

All I get is '404 - File or directory not found.'

Same for any other call or when using python.

Could you tell me what changed so we can fix this?

Thanks in advance,

    Version 2 of our API has been retired, officially on April 29, 2016, but we closed it down a few weeks ago. API v2 users were notified via email with this information a few months prior to the official date.

    The latest version of the API (v2.2) is in beta and offers substantial improvements in performance, functionality and ease of use, so we encourage you to check it out.

    While we strongly recommend updating to v2.2, the easiest option to keep your integration up and running is to migrate to v2.1. The migration should be almost seamless as v2 and v2.1 are operationally very similar.

    Please, sign up for our API email list to stay up to date with any future announcements:

    Best Regards,
