API v2.1 was deprecated more than four years ago (see API Important information) and now, we are in the process of finally retiring it. Once this API v2.1 is retired, you will no longer be able to obtain data via this version.
This article provides answers to the questions you may have and provides guidance with the migration process to the updated and supported API versions.
Why is 7pace retiring API v2.1?
Software is constantly evolving and so are its APIs. The TimeExport endpoint found in API v2.1 does not support pagination and includes all attributes in the response by default. This makes the API less than effective, which leads to occasional performance issues.
7pace provides more recent APIs that can provide the same data, but in an optimized way.
When will API v2.1 be shut down?
Starting on 1st December, 2022, tokens for API v2.1 will be gradually invalidated. Optional prolongation period of limited length (several months) can be requested by an e-mail sent to email@example.com.
How can I tell if I am sending API v2.1 requests?
The API endpoint and version are a part of URL your application is calling, and can be seen in the example, below.
What API should I use as replacement?
The safest way is to use the newest stable version of the API that is listed in our API documentation. Currently it is 3.2.
Note that the TimeExport endpoint no longer exists in the new APIs, you will therefore have to call different endpoints with a different structure of requests. We recommend reading the following documentation:
Choosing a specific endpoint of API v3.2 depends on your needs. The most frequent cases are listed below; the rest of the endpoints are described in the mentioned user guides.
- workLogsOnly endpoint will be the most effective if you only need to obtain worklogs.
- Choose workLogsWorkItems endpoint if you also need to obtain workitems (and, optionally, information about their parent item).
- Note: This endpoint also contains information of a direct parent item of the respective workitem. If you, however, need to obtain the whole hierarchy path for the requested workitem, please wait for a stable API version v3.2 that should be made publicly available during Q3/2022.
Will API v2.1 be shut down for on-prem, too?
If you run Azure DevOps and Timetracker on your own servers, you can continue using API v2.1. However, we do not guarantee that future versions of Timetracker will work with this API properly, and we will not provide troubleshooting support and bugfixing for API v2.1.
What are the differences?
|API version 2.1||API version 3.0 and higher||Comment|
|Limited filtering (start date, end date, flags)||Advanced filtering of records (by any attribute)||We recommend obtaining only updated records for a certain time period using filtering by EditedTimestamp - see Incremental refresh guide.|
|Not paginated||Paginated||Pagination is handled via @odata.nextLink property.
Certain tools - e.g. Excel, Power BI - handle the pagination automatically (you have to choose Odata feed as data source).
|API version in parameters, e.g.
|API version in the base URL, e.g.
|Returns all object attributes (properties) by default||Explicit selection of attributes is enforced due to a newer OData standard||See the respective documentation.|
|Single TimeExport endpoint to rule them all||Multiple endpoints suited for different use cases||See the preceding sections for more information about endpoints.|
