Copy page as markdown [View .md](https://distribution.tech/docs/api/post-plans-id-lines.md) ## Overview Add a creator to a plan awaiting approval by its unit\_id (a format's unit\_id from creators\_search or creator\_get), at that format's current all-in price, the same as the brand adding it in the workspace. Leave out plan\_id (REST: POST /api/v1/plans/current/lines) to add to the brand's newest plan awaiting approval, or to start a plan for this creator when none waits; that also needs the mandate to allow starting a campaign, and counts toward the brand's 3 new campaigns in 24 hours. Only approved creators on sale can be added (not\_approved otherwise). A creator who would take the plan's all-in total over the mandate's maximum plan total, or this month's signed spend plus that total over its monthly cap, is refused (mandate\_refused, over\_max\_plan\_total or over\_monthly\_cap) and the plan is left as it was. A creator who would take the plan's all-in total over its campaign's budget is refused for everyone (conflict, reason over\_budget, with budget\_cents and remaining\_cents, the room left before this creator) and the plan is left as it was; pick a creator priced within remaining\_cents or remove one first. Returns the new line\_id and the plan as plan\_quote returns it. Needs an idempotency\_key. Scope: campaigns:write. MCP tool: plan\_add\_creator. Endpoint `POST https://app.distribution.tech/api/v1/plans/{id}/lines` Scope `campaigns:write` Changes data Yes, send an Idempotency-Key header MCP tool [plan\_add\_creator](https://distribution.tech/docs/mcp/tools/plan-add-creator) ## Parameters | Name | In | Type | Required | Description | | --- | --- | --- | --- | --- | | `id` | path | string (uuid) or one of "current" | Yes | A plan id, or current: the brand's newest plan awaiting approval, or a new plan started for this creator. | | `Idempotency-Key` | header | string | Yes | 8 to 128 letters, digits or . \_ : -. Retry with the same key and the same request to get the same answer; it never runs twice. | ## Request body | Name | Type | Required | Description | | --- | --- | --- | --- | | `unit_id` | string (uuid) | Yes | A format's unit\_id from /creators. | JSON body, every field ``` { "unit_id": "" } ``` ## Request with curl Set `DISTRIBUTION_API_KEY` to a key from Developers with the `campaigns:write` scope, and each path variable to an id from an earlier answer. The body carries the required fields. curl ``` curl -X POST "https://app.distribution.tech/api/v1/plans/$PLAN_ID/lines" \ -H "Authorization: Bearer $DISTRIBUTION_API_KEY" \ -H "Idempotency-Key: $(uuidgen)" \ -H "Content-Type: application/json" \ -d '{ "unit_id": "" }' ``` ## Response `200` OK. The body has these fields: | Name | Type | Required | Description | | --- | --- | --- | --- | | `line_id` | string (uuid) | Yes | | | `plan` | object | Yes | A plan as the person sees it and as an agent signs it (v1-product-spec 8.5 Quote). | 200 response body, every field with its type ``` { "line_id": "", "plan": { "plan_id": "", "campaign_id": "", "version": 0, "status": "awaiting_approval", "currency": "", "launch_window_start": "", "launch_window_end": "", "terms_fingerprint": "", "total_cents": 0, "totals": {}, "lines": [ { "id": "", "creator": { "id": "", "name": "", "handle": "", "profile_url": "", "avatar_url": "", "followers": 0 }, "creator_id": "", "unit_id": "", "stage_id": "planned", "stage": "", "channel": "", "channel_label": "", "format": "", "deliverable": "", "scheduled_date": "", "price_cents": 0, "vetting": "", "reason": "", "expected_views_low": 0, "expected_views_high": 0, "on_sale": false } ], "payment_options": [ { "rail": "checkout", "label": "", "clears": "" } ], "agent_payment": "checkout", "brand_terms": { "current_version": "", "current_number": 0, "url": "", "accepted_for_this_key": "", "accepted_number_for_this_key": 0 }, "mandate": { "key_id": "", "version": 0, "max_plan_cents": 0, "monthly_cap_cents": 0, "channels": [ "" ], "may_approve": false, "may_exceed_budget": false, "expires_at": "", "updated_at": "", "spent_this_month_cents": 0, "terms_version": "", "terms_accepted_at": "", "terms_accepted_email": "" }, "policy": { "allowed": false, "refusal": {} }, "blocked_lines": [ "" ], "over_budget": { "budget_cents": 0, "total_cents": 0, "over_by_cents": 0 }, "order": {}, "valid_while": "terms_fingerprint_unchanged" } } ``` ## Errors | Status | When | | --- | --- | | `400` | A parameter is not valid: details.problems names each field and what it accepts. | | `401` | No API key, an unknown one, or a revoked one. | | `403` | The key lacks the scope, or the mandate refuses (mandate\_refused, with the limit and how much over). | | `404` | No plan, line or creator of yours has that id. | | `409` | conflict (with a reason), idempotency\_conflict, or in\_progress (Retry-After). | | `422` | unprocessable: the body is readable but a value cannot be used (a blank or too long name, a campaign that cannot be planned yet); details.problems names each field when there are several. | | `429` | Too many requests for this key in the current minute (60); Retry-After and RateLimit-Reset say when to try again. On POST /campaigns and on POST /plans/current/lines when it starts a plan: the brand's 3 new campaigns in 24 hours are used (details.reason daily\_campaign\_limit); details.resets\_at and Retry-After say when the limit reopens, a rolling 24 hours from the first of them, not a calendar day; archiving or deleting a campaign does not give its slot back. On GET /creators and GET /creators/{id}: a creator read limit is used (details.reason per\_minute, daily\_lists, daily\_reveals, daily\_seen or locked). daily\_seen is your workspace's one pool of 300 creator views a day (300 different creators shown or opened since midnight UTC), shared by the app and every API key of the brand: details.scope workspace and details.limit 300; a creator already seen today, in the app or through any key, still opens and costs nothing. The other reasons are this key's own limit (details.scope key) or the brand's ceiling over all its keys (details.scope api). | | `500` | internal: the request failed on our side. Retry it with the same Idempotency-Key. | | `503` | unavailable: writes are not available right now (for an approval: payments are not open yet). | ## Related endpoints - [`POST /plans/{id}/approve`](https://distribution.tech/docs/api/post-plans-id-approve): Approve and get the pay link - [`POST /plans/{id}/dates`](https://distribution.tech/docs/api/post-plans-id-dates): Move a plan's dates - [`GET /plans/{id}/quote`](https://distribution.tech/docs/api/get-plans-id-quote): A plan as you sign it - [`DELETE /plans/{id}/lines/{line_id}`](https://distribution.tech/docs/api/delete-plans-id-lines-line-id): Remove a creator - [`POST /plans/{id}/lines/{line_id}/swap`](https://distribution.tech/docs/api/post-plans-id-lines-line-id-swap): Swap a creator ## Get access Keys are created in Developers once your brand is approved.
