Using rest api to update custom field values

[İclal Aslan]

Using Postman to add all projects in Jira as options in a select list field via the REST API, and automatically updating the custom field whenever a new project is added.

Hi @İclal Aslan 

You can use such rest api endpoint: https://developer.atlassian.com/cloud/jira/platform/rest/v3/api-group-issue-custom-field-options/#api-rest-api-3-field-fieldid-context-contextid-option-put.

And you need to create a rule, which will add a new option with this endpoint every time when a new project is added.

Or you can just use the Project Picker field type for your purposes.

Hi @İclal Aslan ,

Welcome to the Atlassian Community!

As per my knowledge, solution is not straight forward. Please consider below steps to achive this.

Step1: Retrieve the list of all projects from a Jira Cloud instance using the REST API, you can use the /rest/api/2/project/search endpoint. This endpoint returns a paginated list of projects, and you'll need to handle pagination if you need to retrieve all projects.

Step2: Having Custom field ID and Context ID, using below REST End point you can update the custom field options with values received from Step1.

Please let me know if you still have any questions.
