## update_custom_field_value

> serde_json::Value update_custom_field_value(field_id_or_key, custom_field_value_update_details, generate_changelog)
Update custom field value

Updates the value of a custom field on one or more issues.  Apps can only perform this operation on [custom fields](https://developer.atlassian.com/platform/forge/manifest-reference/modules/jira-custom-field/) and [custom field types](https://developer.atlassian.com/platform/forge/manifest-reference/modules/jira-custom-field-type/) declared in their own manifests.  **[Permissions](#permissions) required:** Only the app that owns the custom field or custom field type can update its values with this operation.  The new `write:app-data:jira` OAuth scope is 100% optional now, and not using it won't break your app. However, we recommend adding it to your app's scope list because we will eventually make it mandatory.
