# A trial converts to a paying subscription.

`POST member.converted` (webhook)

### When this fires

A trial subscription successfully converts to a paying subscription: the subscription reaches `active` while the subscriber was previously in `trialing` status. Fires exactly once per conversion.

This event is currently emitted for **Stripe only**. Trials taken through PayPal, Paystack, Razorpay, Skrill, CeyPay, or CoinPayments do not produce a conversion event; detect those by watching `payment.succeeded` against a subscription you know began in trial.

### Caveats

- Pairs with `payment.succeeded` for the converting charge. `subscription.activated` does **not** fire at conversion; it already fired when the trialing subscription was first created.
- A subscriber who churns and starts a new trial later does not re-emit `member.converted` for the prior trial; each trial-conversion is its own bounded event.

### Related events

- `member.trial_joined`: predecessor.
- `subscription.activated`: fired earlier, when the trialing subscription was created; it does not repeat at conversion.

## Headers

- `SB-Signature` string, required
- `SB-Event-Id` string, required
- `SB-Event-Name` string, required
- `Content-Type` string, required
- `User-Agent` string, required

## Payload

- object: The envelope every event is delivered in.
  - `id` string, required: A ULID unique to the event, prefixed `evt_`. Every retry carries the same id, so it is the key to deduplicate on.
  - `type` 'member.converted', required: The event name, always `member.converted` here.
  - `created_at` string, date-time, required: When the event was emitted, server time, ISO 8601.
  - `api_version` string, required: The contract version of the payload shape, `2026-05-01` today. A breaking change to a shape ships under a new version.
  - `project_id` string, uuid, nullable, required: The project the event belongs to; null for team-scoped and billing events.
  - `data` object, required: The event-specific payload. Keys that do not apply to a given emission are omitted rather than sent as null, so check for presence.
    - `subscription_id` string, uuid, required: Subscription that converted.
    - `plan_id` string, uuid, required: Plan the subscription is on.
    - `subscriber_id` string, uuid, required: Subscriber's project-scoped user id.
    - `provider` string, required: Provider slug for the converting charge.

## Acknowledgement `2XX`

Your endpoint acknowledged the delivery. Any 2xx status within 30 seconds marks it delivered; the response body is ignored.

## Other responses

- `default`: Any other status, a connection failure, or no answer within 30 seconds counts as a failed attempt. The delivery is retried 8 times, after 10 seconds, 30 seconds, 2 minutes, 10 minutes, 1 hour, 6 hours, 1 day, 3 days; the last failure dead-letters it, and it can be retried from the dashboard or `POST /v1/webhook-deliveries/{delivery}/retry`. After 20 consecutive failures the endpoint is paused until it is resumed.
