Version 7 of the API is already deprecated and will be removed on July 31, 2019

[Lefteris Chatzimparmpas]

Hello Todoist API users and partners,

Since today, we're returning a `Warning` header for all API requests using a version less than 7 (< v7):

curl -vs https://todoist.com/api/v7/sync -d token=$token -d sync_token='*' -d resource_types='["all"]' |& grep "warning: "
< warning: 119 - "Deprecated API version. Will be removed on 2019-07-31"

As you can see above, the version 7 of our API will be removed on July 31, 2019.

Additionally, all other endpoints using a version less than or equal to 7 will return gone after this date, which should be happening for a long time now.

In case you have an application making API calls to any version less than or equal to 7, we strongly recommend you to migrate to v8 as soon as possible to avoid downtime after July 31.

Please contact us if you need any additional information about the API and how to migrate.
