Import tasks into a project

Import tasks into a project from a JSON document (factuarea.tasks.v1, or an export of other task tools in a supported format).

The import is synchronous only and accepts up to 200 tasks per call: more than 200 returns 422, so split the file.
The report lists, per task, its index in the document, the created id and key or the error that prevented it; it has no mode or run_id because the API does not create background import runs.
Requires projects:write only: it creates tasks and comments even if the key has no tasks:write.
Requires an Idempotency-Key.

Client-generated opaque key (up to 255 characters; UUID v7 recommended) that makes retries safe: the first response is cached and replayed for repeats without re-executing the mutation. Reusing a key with a different body returns 409 idempotency_key_reused. See the Idempotency guide. Required on this operation: repeating it delivers an effect that cannot be taken back (an email sent, a file generated, a third-party call, a charge), so a request without this header is rejected with 422 idempotency_key_required before any business logic runs.

Length1 <= length <= 255

Factuarea-Version?string

Pin the API version (YYYY-MM-DD, Stripe-style date versioning) for this request; omit to use the key's pinned version, or the latest if none. Unsupported version → 400 unsupported_api_version; malformed → 400 parameter_invalid_format. The effective version is echoed in the Factuarea-Version response header. See the Versioning guide.

Formatdate

X-Active-Profile?string

Operate on behalf of a child company (gestoría master key): pass its public id (UUID v7) and the request runs against that child's data without changing the key's scope, tier or environment (omit to use the key's own company). Invalid UUID → 400 parameter_invalid_uuid; unknown or non-owned id → 404 profile_not_found. See the Acting on behalf guide.

Request Body

application/json

TypeScript Definitions

Use the request body type in TypeScript.

format?string

Format of the document: factuarea.tasks.v1, the format produced by GET /v1/projects/{project}/tasks/export. It may be omitted when the document is a {project, tasks} JSON file exported from another task manager, which is also accepted.

project?

Data of the source project (key, name, description and columns), as they appear in the exported document.

tasks*array<>

Tasks to import: between 1 and 200 per request. Each element is an object describing one task. Problems inside a task never reject the request: they are reported per task, as warnings or as a failed entry, in the response.

Items1 <= items <= 200

Response Body

`application/json`

Request example

const apiKey = process.env.FACTUAREA_API_KEY;if (!apiKey) throw new Error("Set FACTUAREA_API_KEY");const response = await fetch("https://api.factuarea.com/v1/projects/01931b3e-7c4a-7f2e-9a8b-3c5d6e7f8a01/tasks/import", {  method: "POST",  headers: { Authorization: `Bearer ${apiKey}`, ...{"Accept":"application/json","Content-Type":"application/json","Idempotency-Key":"erp-2026-public-api-v1-projects-tasks-import"} },  body: JSON.stringify({  "tasks": [    {}  ]}),});if (!response.ok) throw new Error(await response.text());if (response.status !== 204) console.log(await response.json());
