## Create **post** `/v1/tasks` Creates a new task record. The `$title` and `$status` fields and the `$assignedTo` relationship are required. If `$createdBy` is omitted it defaults to the authenticated user. The `$note` relationship is read-only — manage notes via their own relationships. Supports idempotency via the `Idempotency-Key` header. **[Required scope](/using-the-api/scopes/):** `tasks:create` **[Rate limit category](/using-the-api/rate-limits/):** Write ### Body Parameters - `fields: object { "$status", "$title", "$description", "$dueAt" }` Field values for the new task. Tasks only support the documented system fields, all prefixed with `$` (e.g. `$title`, `$status`). Required: `$title` (string) and `$status` (one of `TODO`, `IN_PROGRESS`, `COMPLETE`, `CANCELLED`). Call the [definitions endpoint](/api/resources/task/methods/definitions) to discover the available fields. See [Fields and relationships](/using-the-api/fields-and-relationships/) for value type details. - `"$status": string` Task status. One of: `TODO`, `IN_PROGRESS`, `COMPLETE`, `CANCELLED`. - `"$title": string` Title of the task. - `"$description": optional string` Description of the task in markdown format. - `"$dueAt": optional string` Due date as an ISO 8601 datetime string. - `relationships: map[string or array of string]` Relationships to set on the new task. System relationships use a `$` prefix (e.g. `$account`, `$assignedTo`); custom relationships use their bare slug. `$assignedTo` is required. Each value is a single entity ID or an array of IDs. Call the [definitions endpoint](/api/resources/task/methods/definitions) to list available relationship keys. - `UnionMember0 = string` - `UnionMember1 = array of string` ### Returns - `TaskCreateResponse = object { id, createdAt, fields, 4 more }` - `id: string` Unique identifier for the entity. - `createdAt: string` ISO 8601 timestamp of when the entity was created. - `fields: map[object { value, valueType } ]` Map of field names to their typed values. System fields are prefixed with `$` (e.g. `$name`, `$email`); custom attributes use their bare slug. - `value: string or number or boolean or 3 more` The field value, or null if unset. - `UnionMember0 = string` - `UnionMember1 = number` - `UnionMember2 = boolean` - `UnionMember3 = array of string` - `Address = object { city, country, latitude, 5 more }` - `city: optional string` City name. - `country: optional string` 2-letter ISO 3166-1 alpha-2 country code. - `latitude: optional number` Latitude coordinate. - `longitude: optional number` Longitude coordinate. - `postalCode: optional string` Postal or ZIP code. - `state: optional string` State or province. - `street: optional string` Street address line 1. - `street2: optional string` Street address line 2. - `FullName = object { firstName, lastName }` - `firstName: optional string` The contact's first name. - `lastName: optional string` The contact's last name. - `valueType: "ADDRESS" or "CHECKBOX" or "CURRENCY" or 11 more` The data type of the field. - `"ADDRESS"` - `"CHECKBOX"` - `"CURRENCY"` - `"DATETIME"` - `"EMAIL"` - `"FULL_NAME"` - `"MARKDOWN"` - `"MULTI_SELECT"` - `"NUMBER"` - `"SINGLE_SELECT"` - `"SOCIAL_HANDLE"` - `"TELEPHONE"` - `"TEXT"` - `"URL"` - `httpLink: string` URL to view the entity in the Lightfield web app, or null. - `relationships: map[object { cardinality, objectType, values } ]` Map of relationship names to their associated entities. System relationships are prefixed with `$` (e.g. `$owner`, `$contact`). - `cardinality: string` Whether the relationship is `has_one` or `has_many`. - `objectType: string` The type of the related object (e.g. `account`, `contact`). - `values: array of string` IDs of the related entities. - `updatedAt: string` ISO 8601 timestamp of when the entity was last updated, or null. - `externalId: optional string` External identifier for the entity, or null if unset. ### Example ```http curl https://api.lightfield.app/v1/tasks \ -H 'Content-Type: application/json' \ -H 'Lightfield-Version: 2026-03-01' \ -H "Authorization: Bearer $API_KEY" \ -d '{ "fields": { "$status": "$status", "$title": "$title" }, "relationships": { "foo": "string" } }' ```
