subscription.trial_started
Trial-enabled plan starts free window.
When this fires
A subscriber starts a trial on a trial-enabled plan. Three paths emit it: a cardless trial, an access-code redemption against a trial plan, or a Stripe checkout that begins in a trial window.
Trial checkouts through the other providers (PayPal, Paystack, Razorpay, Skrill, CeyPay, CoinPayments) do not currently emit this event; only Stripe reports the trialing status transition back to Subscriby.
Pairs with
member.trial_joined: both fire together when a subscriber starts a trial on the cardless-trial and access-code paths.
The data keys differ by path. Absent keys are omitted entirely, not sent as null.
Caveats
- On the cardless-trial and access-code paths this is paired with
subscription.createdandmember.trial_joinedfor the samesubscription_id. On the Stripe path it is paired withsubscription.activatedinstead, and nomember.*join event fires. - Plans with
trial_days = 0skip this event entirely.

Ability to subscribe
A token needs this to subscribe an endpoint to the event.
Header Parameters
t=<unix seconds>,v1=<hex>: the HMAC-SHA256 of "<t>.<raw body>" under the endpoint's secret. Verify it before acting, and refuse a t more than 300 seconds from now. During a secret rotation a v0= signature under the previous secret may precede v1=.
The event's ULID, bare. The envelope's id is the same ULID prefixed evt_, so strip the prefix before comparing. Deduplicate on it: a retry carries the same id.
The event name, the same as the envelope's type.
Always application/json.
Always Subscriby-Webhooks/1.0.
Payload
JSONWhat Subscriby posts to your endpointapplication/json

The envelope every event is delivered in.
Responses
2XXAny success status
Your endpoint acknowledged the delivery. Any 2xx status within 30 seconds marks it delivered; the response body is ignored.
defaultAny other status
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.
