Update a project work item template

PATCH/api/v2/workspaces/{slug}/projects/{project_id}/work-item-templates/{pk}/

Project work item templates pre-fill new work items in one project. Update a project work item template. Work items already created from the template don't change.

The update is partial for the top-level fields. Send only the ones you want to change, and anything you omit keeps its current value. template_data is the exception. When you send it, it replaces the whole seed, as described under Body Parameters.

Path Parameters

slug:requiredstring

The workspace slug. It appears in your Plane URLs. In https://app.plane.so/my-team/projects/, the slug is my-team.

project_id:requiredstring

The project the resource belongs to. Accepts the project UUID or its bare identifier, for example ENG.

pk:requiredstring (uuid)

The project work item template id.

Body Parameters

description_html:optionalstring

Rich-text body as HTML. This is the field the Plane editor round-trips.

is_published:optionalboolean

Whether the template is published.

name:optionalstring

Display name.

Maximum 255 characters. Plane doesn't validate the top-level fields on update, so a longer name or a null returns 500 server_error.

short_description:optionalstring

The short description.

Nullable.

template_data:optionalobject

A new work item seed. It replaces the stored seed as a whole, so send every key you want to keep:

• name (string, required). Title of the work item created from the template. Maximum 255 characters.
• description_html (string). Resets to <p></p> when omitted.
• priority (string). One of urgent, high, medium, low, or none. Resets to none when omitted.
• state (object). Resets to {} when omitted.
• assignees (array). Resets to [] when omitted.
• labels (array). Resets to [] when omitted.
• type (object). Resets to {} when omitted.
• modules (array). Resets to [] when omitted.
• properties (array). Resets to [] when omitted.

Omit template_data entirely to leave the seed alone.

Response shaping

fields:optionalstring

Comma-separated list of fields to return. Unrequested keys are omitted, not returned as null. id always comes back. Pass all for every requestable field. An unknown name is a 400. See Sparse fields.

Requestable here: created_at, created_by_id, description_html, id, is_published, name, short_description, short_id, slug, template_data, template_type, updated_at, updated_by_id.
