After successful creation, an option `item` that can be directly used for publishing tasks is returned. All additional parameters on the platform side that "need to be created first and then selected" are processed through this interface. For example, Pinterest needs to create a Board first, and then use the returned Board as the publishing target `boardId`. Calling process: First call the ["Platform Publish Options"](/en/api-reference/get-api-v2-channels-platforms-platform-publish-options) interface (`GET /api/v2/channels/platforms/{platform}/publish-options`) to query what additional parameters the platform has; only fields whose return items contain `createSchema` are supported for creation. Put the `field` in the return item into the path parameter `field` of this interface, and organize the JSON request body according to the `createSchema`. For fields that do not need to be created, please call the ["Publish option optional values"](/en/api-reference/get-api-v2-channels-accounts-account-id-publish-options-field-values) interface to query and select. ## OpenAPI ````yaml /openapi/en/aitoearn.openapi.json post /api/v2/channels/accounts/{accountId}/publish-options/{field}/values openapi: 3.0.1 info: title: AiToEarn Open Platform API description: >- AiToEarn Open Platform API.
