I'm using the dynamics CRM REST API to create projects, and manage some actions on Microsoft Projects online.
We're using labels, which we can apply to tasks, to signify various things.
Via the API I can read labels, and I can read and write the labels that have been assigned to each task (msdyn_projecttask).
The bit I haven't succeeded with is creating an API call which will change the text of a label from the default (Pink, Red, Yellow etc.) to something more useful.
Currently I'm having to manually edit the label text via the Project User Interface (e.g. see below).
Once I've renamed the label, when I fetch them via the API I can see the changed text, but I can't figure out a way to change it.
I'm able to fetch the project labels via:
GET orgXYZABC.api.crm4.dynamics.com/.../msdyn_projectlabels
(where {projectId} is the msydn_projectid of my project)
Which returns data like:
Share
Report{
"@odata.context":"https://orgXYZABC.api.crm4.dynamics.com/api/data/v9.1/$metadata#msdyn_projectlabels",
"value":[
{
"@odata.etag":"W/\"21783358\"",
"_owningbusinessunit_value":".....",
"statecode":0,
"msdyn_colorindex":192350000,
"statuscode":1,
"_createdby_value":"....",
"_ownerid_value":".....",
"_owningteam_value":".....",
"modifiedon":"2022-11-02T13:32:26Z",
"_modifiedby_value":"....",
"versionnumber":21783358,
"_msdyn_projectid_value":".....",
"createdon":"2022-11-02T13:32:26Z",
"msdyn_projectlabelid":"625eb1b2.....",
"_owninguser_value":null,
"overriddencreatedon":null,
"importsequencenumber":null,
"_modifiedonbehalfby_value":null,
"msdyn_projectlabeltext": "Label One",
"utcconversiontimezonecode":null,
"_createdonbehalfby_value":null,
"timezoneruleversionnumber":null
},
....
]
}
I've tried:
PATCH orgXYZABC.api.crm4.dynamics.com/.../msdyn_projectlabels({labelId}})
(where {labelId} is one of the msdyn_projectlabelid values returned above)
headers: [
"If-Match: *",
"OData-MaxVersion: 4.0",
"OData-Version: 4.0",
"Accept: application/json",
"Authorization: ...",
"Content-Type: application/json; charset=utf-8"
]
body: {
"msdyn_projectlabeltext": "Test Label 1"
}
But it fails and says:
"We\u2019re sorry. You cannot directly do 'Update' operation to 'msdyn_projectlabel'. Try editing it through the Resource editing UI via Project."
And I've tried:
PATCH https://orgXYZABC.api.crm4.dynamics.com/api/data/v9.1/msdyn_projectlabels
headers: [
"If-Match: *",
"OData-MaxVersion: 4.0",
"OData-Version: 4.0",
"Accept: application/json",
"Authorization: ...",
"Content-Type: application/json; charset=utf-8"
body: {
"msdyn_projectlabeltext": "Test Label 1"
"msdyn_projectlabelid@odata.bind": "/msdyn_projectlabels({labelId})"
}
Which fails, saying:
"The requested resource does not support http method 'PATCH'."
Also tried:
PUT https://orgXYZABC.api.crm4.dynamics.com/api/data/v9.1/msdyn_projectlabels({labelId})/msdyn_projectlabeltext
headers: [
"OData-MaxVersion: 4.0",
"OData-Version: 4.0",
"Accept: application/json",
"Authorization: ...",
"Content-Type: application/json; charset=utf-8"
]
body: {
"value": "Test Label 1"
}
But it fails with the same error as above.
There doesn't seem to be any documentation for this anywhere, if you google "msdyn_projectlabel" or "msdyn_projectlabels" (in quotes) you don't get a single result!
Anyone out there have any knowledge on whether this is possible / how to succeed?
