REST API for setting multi select field type in Azure DevOps

Sachin Sarawgi 1 Reputation point

Hi, I have installed the following plugin to support the multi-value type field in Azure DevOps,used%20to%20back%20the%20extension.

I am able to configure the option for this field by separating using "semicolon". like "A; B; C".
I can also see this field in my work item and able to set the values.

I need help with how can I update this multivalue type field through REST API.
I want to change the value of the work item which has this multi-value type field through REST API. I have already tried updating them using the following approaches

  1. "A; B"
  2. "A, B"
  3. "[A, B]"
  4. "A;B"
  5. "A,B"

It sets up the value which I am sending using option 1, but it adds those as an extra option though the option already exists with that value.
I can see extra spaces on the option which I am sending through REST API, but I have checked my JSON there is no extra space (using option 4).

    Hi @Sachin Sarawgi

    DevOps is currently not supported in the Q&A forums, the supported products are listed over here (more to be added later on).

    You can ask the experts in the dedicated forum over here:
