Same rules as the **Accept** modal on the CPL Campaigns page: - **Trial campaigns** need `trial_days`, chosen from the campaign's own list (default list: 1, 3, 7, 14, 30, 90, 180, 360). - **OT tracking-link campaigns without a predefined link** need `fallback_url`: the OnlyFans page a fan lands on, `https://onlyfans.com/…`, max 255 characters. Other campaigns ignore both fields. Returns the campaign as one `/api/marketer/cpl/campaigns` row with `status` = `accepted`. **Errors** (`status: "error"`, HTTP 200): - `404` `Order not found`. - `422` `Choose a trial period: 1 | 3 | 7 | 14 | 30 | 90 | 180 | 360` (the list is the campaign's own), `Fallback URL is required and must start with https://onlyfans.com/`, or the platform's message when the campaign can no longer be accepted. - `403` Access denied: missing / unknown key, or the account is not an active partner. - `429` Rate limit exceeded (30 writes per minute per key, see the `Retry-After` header). - `503` Service is temporarily unavailable: the platform did not answer in time. The action may still have been applied, check the matching read endpoint before repeating it. Same as **Accept** on the CPL Campaigns page. `order_id` is the `cplo_…` public id from [`/api/marketer/cpl/campaigns`](/docs/partners/api/cpl-campaigns); the campaign must be in `waiting` status. ## Conditional fields Two fields are required only for some campaigns, exactly like the Accept modal: | Field | When it is required | | -------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------- | | `trial_days` | Trial campaigns. Must be one of the campaign's allowed values; the default list is 1, 3, 7, 14, 30, 90, 180, 360 | | `fallback_url` | Campaigns on an OT tracking link without a predefined link. The OnlyFans page a fan lands on: must start with `https://onlyfans.com/`, max 255 characters | Other campaigns ignore both. `comment` is optional and shown to the client. ## Errors | Message | Meaning | | -------------------------------------------------------------------- | --------------------------------------------------------------- | | `Order not found` | Unknown id, not your campaign, or a numeric internal id (`404`) | | `Choose a trial period: 1 \| 3 \| 7 \| …` | `trial_days` missing or not in the campaign's list (`422`) | | `Fallback URL is required and must start with https://onlyfans.com/` | `fallback_url` missing or invalid (`422`) | | Platform text | The campaign can no longer be accepted (`4xx`) | ## OpenAPI ````yaml api/openapi-partners.json POST /api/marketer/cpl/campaigns/accept openapi: 3.0.2 info: title: OnlyTraffic Marketer API version: 2.1.0 description: >- Partner (marketer) API for OnlyTraffic. **Authentication:** pass your API key in the `Authorization` header (`Authorization: your-api-key` or `Authorization: Bearer your-api-key`). Create keys in the partner cabinet: Tools -> API (https://partners.onlytraffic.com/tools/api). Up to 5 named keys per account, each **Full** or **Read-only**, with an optional expiry. Keys start with `ot_partners_` and are shown once, at creation. Read-only keys cannot call the `POST` endpoints (`error_code` 403, message `This API key is read-only`). An older legacy key keeps working with full access until you delete it on the same page. **Pagination:** all list endpoints accept `offset` (default 0) and `limit` (default 50, max 1000) as query parameters or JSON body fields. **Dates:** every timestamp field has two variants — an ISO 8601 string (`*_at`) and a Unix timestamp integer (`*_at_ts` / `*_ts`). **Writes:** a Full-access key reads and writes. Write endpoints are `POST` with a JSON body, accept public ids only (`revc_…`, `cplo_…`) and answer with the updated object in `data`. Rate limit: 120 requests per minute for reads, 30 per minute for writes, per account (shared by all its keys). servers: - url: https://partners.onlytraffic.com security: [] tags: - name: RevShare description: RevShare campaigns and financial data - name: CPL description: Cost-Per-Lead orders placed against your offers - name: CPC description: Cost-Per-Click orders and the category catalog - name: Subscribers description: Fans acquired through your campaigns - name: Stats description: Dashboard-style statistics widgets (fans, income, conversion) - name: Write description: >- Write API: start / stop / update campaigns and accept / reject / stop CPL campaigns (same key, same rules as the cabinet) paths: /api/marketer/cpl/campaigns/accept: post: tags: - Write summary: Accept a CPL campaign description: >- Accepts a waiting campaign placed on your CPL offer.
