Manually enrolls the contact into an active flow; this alias takes no request body, so use the email-flows route when you need `dynamic_context`. Fails with `409` if the contact is already in the flow (`campaign_flow_already_in_flow`), blocked by `no_reentry` (`campaign_flow_reentry_denied`), or the flow is not active (`campaign_flow_not_active`). ## OpenAPI ````yaml /api-reference/openapi.json post /v1/email-campaigns/{campaignId}/contacts/{contactId} openapi: 3.1.0 info: title: Tented API version: 1.0.0 description: >- The Tented public API: generate, publish, and manage AI-built web pages (tents), and run the email platform — contacts, reusable emails, one-time blasts, and triggered flows. ## Authentication Authenticate every request with a workspace API key: `Authorization: Bearer `. Keys are created in **Workspace Settings → API Keys** and are scoped to a single workspace. ## Asynchronous work Tent generation, bulk creation, and email AI generation return `202 Accepted` immediately. Poll the corresponding status endpoint (`GET /v1/tents/{tentId}`, `GET /v1/bulk-jobs/{bulkJobId}`, `GET /v1/emails/{emailId}/generations/{generationId}`) — no more than every 10 seconds. ## Pagination Email listings use cursor pagination (`cursor`/`next_cursor`). Blast, flow, and member listings use page pagination (`page`/`limit` with a `pagination` object in the response). ## Conventions Request and response fields are snake_case, with two exceptions: analytics query parameters (`tentIdOrAlias`, `daysBack`) and segment rule trees (camelCase keys such as `listId` and `timeWindow`). contact: name: Tented Support email: support@tented.ai servers: - url: https://api.tented.ai description: Production security: - bearerAuth: [] tags: - name: Tents description: >- Create, edit, publish, and manage AI-generated pages, including asset uploads and bulk creation. - name: Analytics description: Traffic analytics for single tents and the whole workspace. - name: Contacts description: >- Batch create, update, and delete contacts.
