3. Update an artifact

As seen in the previous section Query the artifacts, retrieving information is done through GET requests while update operations are done through POST, PUT, PATCH or DELETE requests.

  • POST: create a resource,

  • PUT: Update a resource,

  • PATCH: Update partially a resource,

  • DELETE: delete a resource.


The difference between PUT and PATCH is minimal. Usually the PUT takes the whole resource as arguments, whereas the PATCH takes only what need to be modified. Usage of PUT vs PATCH will depends on the route.

3.1. Basic usage

To update an artifact we have to provide an artifact representation (take the one coming from the GET /artifacts/:id as an example) with updated values.

$ curl -XPUT --header 'Content-type: application/json' \
    --header 'X-Auth-AccessKey: tlp.k1.1026…'
    -d '{"values":[{"field_id": 694, "bind_value_ids": [597]}], "comment": {"body": "some comments", "format": "text"}}' \

HTTP/1.1 200 OK
values correspond to the new field values :
  • 694 is the id of our Status field

  • 597 is the id of the value Delivered

comment is to add a new follow-up :
  • body is the follow-up’s content

  • format is the follow-up’s format


Remember that you can get the id of the fields and values by getting the structure of the tracker thanks to the route trackers/123.

The server returned a 200 status code, meaning that the artifact is successfully updated.


3.2. Conclusions

Now we are able to:

  • Do authenticated calls

  • Do a basic GET to retrieve information (projects, trackers, artifacts, …)

  • Handle pagination

  • Update a resource with a PATCH or PUT

That’s it! You have most of the resources needed to use the various REST routes provided by Tuleap. We strongly suggest that you use the API explorer (https://tuleap.example.com/api/explorer/) which documents all the routes and let you try them on the fly without having to manage an authentication token or type a curl command.

It’s the end of this REST API Quick Start, you can now use your favorite programming language to enhance Tuleap capabilities.

Happy hacking!
