## Create **post** `/v1/opportunities` Creates a new opportunity record. The `$name` and `$stage` fields and the `$account` relationship are required. After creation, Lightfield automatically generates an opportunity summary in the background. The `$opportunityStatus` field is read-only and cannot be set via the API. The `$task` and `$note` relationships are also read-only — manage them via the `$opportunity` relationship on the task, or the `$account`/`$opportunity` note relationships instead. Supports idempotency via the `Idempotency-Key` header. **[Required scope](/using-the-api/scopes/):** `opportunities:create` **[Rate limit category](/using-the-api/rate-limits/):** Write ### Body Parameters - `fields: object { "$name", "$stage" } or map[string or number or boolean or 2 more]` Field values for the new opportunity. System fields use a `$` prefix (e.g. `$name`, `$stage`); custom attributes use their bare slug. Required: `$name` (string) and `$stage` (option ID or label). Fields of type `SINGLE_SELECT` or `MULTI_SELECT` accept either an option ID or label from the field's `typeConfiguration.options` — call the [definitions endpoint](/api/resources/opportunity/methods/definitions) to discover available fields and options. See [Fields and relationships](/using-the-api/fields-and-relationships/) for value type details. - `UnionMember0 = object { "$name", "$stage" }` - `"$name": string` Display name of the opportunity. - `"$stage": string` Pipeline stage (`SINGLE_SELECT`). Pass the option ID or label from the field definition. - `UnionMember1 = map[string or number or boolean or 2 more]` - `UnionMember0 = string` - `UnionMember1 = number` - `UnionMember2 = boolean` - `UnionMember3 = array of string or number or boolean or 2 more` - `UnionMember0 = string` - `UnionMember1 = number` - `UnionMember2 = boolean` - `UnionMember3 = array of unknown` - `UnionMember4 = map[unknown]` - `UnionMember4 = map[string or number or boolean or 2 more]` - `UnionMember0 = string` - `UnionMember1 = number` - `UnionMember2 = boolean` - `UnionMember3 = array of unknown` - `UnionMember4 = map[unknown]` - `relationships: object { "$account", "$champion", "$createdBy", 2 more } or map[string or array of string]` Relationships to set on the new opportunity. System relationships use a `$` prefix (e.g. `$account`, `$owner`); custom relationships use their bare slug. `$account` is required. Each value is a single entity ID or an array of IDs. Call the [definitions endpoint](/api/resources/opportunity/methods/definitions) to list available relationship keys. - `UnionMember0 = object { "$account", "$champion", "$createdBy", 2 more }` - `"$account": string or array of string` ID of the account this opportunity belongs to. - `UnionMember0 = string` - `UnionMember1 = array of string` - `"$champion": optional string or array of string` ID of the contact who is the internal champion. - `UnionMember0 = string` - `UnionMember1 = array of string` - `"$createdBy": optional string or array of string` ID of the user who created this opportunity. - `UnionMember0 = string` - `UnionMember1 = array of string` - `"$evaluator": optional string or array of string` ID of the contact who is the evaluator. - `UnionMember0 = string` - `UnionMember1 = array of string` - `"$owner": optional string or array of string` ID of the user who owns this opportunity. - `UnionMember0 = string` - `UnionMember1 = array of string` - `UnionMember1 = map[string or array of string]` - `UnionMember0 = string` - `UnionMember1 = array of string` ### Returns - `OpportunityCreateResponse = object { id, createdAt, fields, 2 more }` - `id: string` Unique identifier for the entity. - `createdAt: string` ISO 8601 timestamp of when the entity was created. - `fields: map[object { value, valueType } ]` Map of field names to their typed values. System fields are prefixed with `$` (e.g. `$name`, `$email`); custom attributes use their bare slug. - `value: string or number or boolean or 2 more` The field value, or null if unset. - `UnionMember0 = string` - `UnionMember1 = number` - `UnionMember2 = boolean` - `UnionMember3 = array of string or number or boolean or 2 more` - `UnionMember0 = string` - `UnionMember1 = number` - `UnionMember2 = boolean` - `UnionMember3 = array of unknown` - `UnionMember4 = map[unknown]` - `UnionMember4 = map[string or number or boolean or 2 more]` - `UnionMember0 = string` - `UnionMember1 = number` - `UnionMember2 = boolean` - `UnionMember3 = array of unknown` - `UnionMember4 = map[unknown]` - `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. ### Example ```http curl https://api.lightfield.app/v1/opportunities \ -H 'Content-Type: application/json' \ -H 'Lightfield-Version: 2026-03-01' \ -H "Authorization: Bearer $API_KEY" \ -d '{ "fields": { "$name": "$name", "$stage": "$stage" }, "relationships": { "$account": "string" } }' ```
