List an initiative's projects

GET/api/v2/workspaces/{slug}/initiatives/{pk}/projects/

Return the projects on an initiative as full project objects, paginated. The initiative's own project_ids gives you the ids. This list gives you the projects behind them in one call, so you don't have to fetch each project separately.

The list checks the initiative first, then each project's own visibility. An initiative you can't see returns 404. Projects you can't see are left out of the page. Archived projects stay in the list. Check archived_at to tell them apart.

This is the read half of the route. To change the projects on the initiative, POST to the same path, as described in Add or remove initiative projects, or replace the whole set with project_ids on Update an initiative.

This list takes no filters and no search. To go from an initiative to its work items in one call, use List an initiative's work items, or pass initiative_id to List work items across a workspace when you also need to filter them.

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.

pk:requiredstring (uuid)

The initiative whose projects you want to list.

Ordering

Rows come back in a fixed order, newest first by each project's own created_at, not by when the project joined the initiative. id breaks ties. The order is not configurable, and an order_by you send is ignored.

Pagination

per_page:optionalinteger

Page size. Defaults to 50, maximum 200.

offset:optionalinteger

Number of rows to skip from the start of the result set. Maximum 10000. Read the next value from the response rather than computing offsets yourself.

count:optionalboolean

Defaults to true. Set to false to skip the COUNT(*) behind total_count. The field is then omitted from the response.

Response shaping

fields and expand apply to the project rows, not to the initiative.

fields:optionalstring

Comma-separated list of fields to return on each row. Unrequested keys are omitted from the response, not returned as null, so absent means "not requested" and null means "actually null". id always comes back whether or not you name it.

Pass all for every requestable field. An unknown name is a 400 that lists the valid set and suggests the closest match, so a typo can't silently cost you the saving.

Requestable here: archive_in, archived_at, close_in, cover_image, cover_image_url, created_at, created_by_id, cycle_view, default_assignee_id, default_state_id, description, description_html, emoji, estimate_id, external_id, external_source, guest_view_all_features, icon_prop, id, identifier, intake_view, is_issue_type_enabled, is_time_tracking_enabled, issue_views_view, logo_props, module_view, name, network, page_view, priority, project_lead_id, start_date, state_id, target_date, timezone, updated_at, updated_by_id.

description_html is left off the rows by default. Name it in fields to get it back.

See Sparse fields.

expand:optionalstring

Comma-separated relations to embed alongside the ids: default_assignee (the user new work items are assigned to by default), project_lead (the project lead).

Expansion is separate-key: ?expand=project_lead keeps project_lead_id and adds a project_lead object next to it, so an id is never replaced by an object. An unknown value is a 400.

?fields= and ?expand= are independent namespaces. Relation names are not valid ?fields= tokens (and vice versa), and an expanded object survives field filtering. See Expanding relations.

Scopes
