# PUT /api/external/subscription — Set the creator’s subscription tier

> Creates or replaces the creator's subscription tier. This is a full replace: fields you leave out go back to their defaults (`trialDays` 0, no description or pitch, active).

- Source: https://www.dropfans.io/developers/reference/update-subscription
- Section: API reference
- OpenAPI: https://www.dropfans.io/developers/openapi.json

Creates or replaces the creator's subscription tier. This is a full replace: fields you leave out go back to their defaults (`trialDays` 0, no description or pitch, active).

Same rules as the dashboard: `priceUsd` is USD **dollars**, either `0` (free) or between $5 and $750. `isActive: false` pauses new sign-ups. Existing subscribers keep the price they signed up at.

## Authentication

`Authorization: Bearer dpfn_...` — an API key generated in the dashboard (Vault → API Connect). By default the key acts for the one account it belongs to. Missing or invalid keys return 401 `{"error":"Unauthorized","code":"unauthorized"}`.

Optional `X-Dropfans-Account: <account id>` — with a verified agency's own key, act for a creator or AI persona the agency manages (ids from GET /api/external/agency/creators); the agency needs `canEditProfile` on that account. The response echoes the account acted on in the same header.

## Request body (application/json)

| Field | Type | Required | Description |
|---|---|---|---|
| `priceUsd` | number | yes | USD dollars per interval. 0 = free; otherwise $5–$750. Rounded to cents. |
| `interval` | `monthly` \\| `weekly` | yes | Billing interval. |
| `trialDays` | integer |  | Free trial length in days. |
| `description` | string |  | What subscribers get (cut at 500 characters). |
| `pitchMessage` | string |  | Short pitch shown in the subscribe sheet (cut at 500 characters). |
| `isActive` | boolean |  | false pauses new sign-ups. |

Example — $9.99 a month:

```json
{
  "priceUsd": 9.99,
  "interval": "monthly",
  "description": "All my sets, first."
}
```

## Responses

### 200

The saved tier.

| Field | Type | Required | Description |
|---|---|---|---|
| `tier` | SubscriptionTier | yes | The tier now in effect. |

```json
{
  "tier": {
    "priceUsd": 9.99,
    "currency": "USD",
    "interval": "monthly",
    "trialDays": 0,
    "description": "All my sets, first.",
    "pitchMessage": null,
    "isActive": true
  }
}
```

## Errors

| Status | Body | When |
|---|---|---|
| 400 | `{"error":"priceUsd must be 0 (free) or at least 5"}` | `priceUsd` missing, not a number or negative. |
| 400 | `{"error":"The minimum price is $5. Set the price to free or at least $5."}` | Priced above 0 but below $5. |
| 400 | `{"error":"The maximum price on Dropfans is $750. To request an increase, contact support@dropfans.io."}` | Priced above $750. |
| 400 | `{"error":"interval must be 'monthly' or 'weekly'"}` | Missing or unknown interval. |
| 400 | `{"error":"trialDays must be a whole number from 0 to 30"}` | Bad trial length. |
| 400 | `{"error":"isActive must be true or false"}` | `isActive` is not a boolean. |
| 400 | `{"error":"Invalid JSON body"}` | The body is not valid JSON. |
| 401 | `{"error":"Unauthorized","code":"unauthorized"}` | Missing or invalid API key. |
| 400 | `{"error":"X-Dropfans-Account must be an account id (from GET /api/external/agency/creators), not a username.","code":"invalid_account_header"}` | `X-Dropfans-Account` is not an account id. |
| 403 | `{"error":"This key cannot act for that account.","code":"account_not_managed"}` | `X-Dropfans-Account` names an account this key cannot act for: not an agency’s own key, no ACCEPTED management, or the agency or account is suspended, banned or deleted (an unknown id gets the same answer). |
| 403 | `{"error":"The agency does not have permission for this on that account.","code":"permission_denied","permission":"canEditProfile"}` | With `X-Dropfans-Account`: the agency lacks `canEditProfile` on that account. |

## Rate limiting

Per-key fixed windows by tier (Personal 60/min · 5,000/day; approved apps 300/min · 50,000/day; Dropfans-operated integrations exempt). Read the live values from X-RateLimit-Tier, X-RateLimit-Limit, X-RateLimit-Remaining, X-RateLimit-Reset and their -Day variants; a 429 carries Retry-After and `{"error":"Rate limit exceeded","code":"rate_limited"}`. See [Rate limits](https://www.dropfans.io/developers/concepts/rate-limits.md).
