Webhook Endpoints API
A webhook endpoint is a URL of yours that Subscriby posts events to, with the event families it subscribes to and a signing secret you verify each delivery against.
A webhook endpoint is a URL of yours that Subscriby posts events to, with the event families it subscribes to and a signing secret you verify each delivery against. An endpoint belongs to the team and may be narrowed to one project; the secret is shown exactly twice, in the answer to registering the endpoint and in the answer to rotating it, and never appears on a read.
Each endpoint carries its delivery health: the last success and failure, and disabled_at when Subscriby switched it off after too many consecutive failures or when someone paused it. Pause and resume are the dashboard's on/off switch, and events raised while paused are not queued or replayed; test enqueues a synthetic delivery so a new handler can be checked before real traffic; rotate secret revokes the old secret at once, so deploy the new one first. The delivery log and the replay of a dead-lettered row live under webhook deliveries.
Every member of the team may list and read endpoints, but only the member who registered one, or the team owner, may rotate, test, pause, resume or delete it. The same routes answer under the /v1/webhook-subscriptions alias so Zapier's subscribe and unsubscribe hooks can target them directly. Endpoint lifecycle emits no webhooks of its own, since that would be recursive.
Background
The webhook-subscriptions alias
GET, POST /v1/webhook-subscriptions and DELETE /v1/webhook-subscriptions/{endpoint} are 1:1 aliases of the list, create and delete endpoints below, so Zapier's subscribe and unsubscribe hooks can target them directly. They take the same abilities, bodies and answers and are not listed separately. The retired umbrella ability webhook-endpoint:manage still satisfies every route here on tokens that carry it; new tokens take the per-verb abilities.
Who may change an endpoint
Every member of the team can list and read the team's endpoints, but only the member who registered an endpoint, or the team owner, may rotate its secret, test it, pause or resume it, or delete it. A token minted by another member receives 403 FORBIDDEN on those calls; an endpoint outside the token's team is a 404 RESOURCE_NOT_FOUND, never a 403, so an id cannot be probed.

Query Parameters
The 1-based page to return. A page past the last answers an empty data array with meta.total still filled, so a loop can stop without guessing.
1 <= value1Rows per page, 1 to 100. A higher value clamps to the cap silently. Defaults to 15.
1 <= value <= 10015The column to order by. Defaults to created_at; a column the endpoint does not offer falls back to the default rather than failing.
"created_at"asc or desc. Defaults to desc.
"desc"Value in
- "asc"
- "desc"
Responses
200OKapplication/json
The team's endpoints without their secrets.
401UnauthorizedAUTHENTICATION_REQUIREDapplication/json
The request carries no bearer token, or one that is revoked, malformed, or minted for another environment (an sbt_test_ token on production).
403ForbiddenTOKEN_MISSING_ABILITYapplication/json
The token is valid but does not carry the ability this endpoint requires; error.context.required_ability names the one to grant. An endpoint that also checks who owns a row or which tier the account is on answers FORBIDDEN, TEAM_TIER_REQUIRED or CONNECTOR_TIER_REQUIRED with the same status, and says so in its own description.
429Too many requestsRATE_LIMITEDapplication/json
The token has spent its 300 requests a minute or 10,000 an hour; Retry-After says when the next one is accepted.
curl -X POST https://api.subscriby.net/v1/webhook-endpoints \ -H "Authorization: Bearer $SUBSCRIBY_TOKEN" \ -H "Idempotency-Key: $(uuidgen)" \ -H "Content-Type: application/json" \ -d '{ "name": "Zapier trigger", "url": "https://hooks.zapier.com/hooks/catch/...", "events": ["subscription.created", "payment.succeeded"] }'Answers 201 with the endpoint and, at the top level beside data, the plaintext signing secret.
The secret appears once. The plaintext
secret(prefixedwhsec_) appears at the top level of the response only here and on rotate-secret. Subsequent reads never surface it; copy it into your consumer's secret storage immediately.
Requires ability
The token must hold this ability, or the call is refused with 403.

Idempotent
Send the header on every call; the same key replays the original response for 24 hours.

In: header
Header Parameters
A key unique to this operation, such as a fresh UUID. The same key replays the original 2xx response for 24 hours (with Idempotent-Replay: true), so a retry after a timeout never repeats the write; the same key with a different body is refused with 409.
uuidRequest body
JSONWhat the request carriesRequiredapplication/json
A webhook endpoint to register: where to post, which events, and how to confine it. The signing secret is minted by Subscriby and returned once beside the endpoint.
Responses

201 with the resource and a top-level secret.
400Bad requestIDEMPOTENCY_KEY_MISSINGapplication/json
Every write needs an Idempotency-Key header. Send a fresh UUID per distinct operation.
401UnauthorizedAUTHENTICATION_REQUIREDapplication/json
The request carries no bearer token, or one that is revoked, malformed, or minted for another environment (an sbt_test_ token on production).
403ForbiddenTOKEN_MISSING_ABILITYapplication/json

404Not foundTENANT_MISMATCHapplication/json
With reason: missing_team_scope when the token carries no team scope.
409ConflictIDEMPOTENCY_KEY_REUSEDapplication/json
The key was already used in the last 24 hours with a different request body.
422Validation failedVALIDATION_FAILEDapplication/json
The payload broke a rule, and error.fields maps each offending key to its messages. A refusal from the domain, such as a plan that cannot go on sale or a member who cannot be removed, uses the same code with error.message saying why and no fields.
On this endpoint: VALIDATION_FAILED: when url is not https://, points at a private or reserved host, or exceeds 2,048 characters; when events is empty or names an unknown event; when allowed_ips holds an invalid address or range; when name is outside 3 to 100 characters.
425Too earlyIDEMPOTENCY_REPLAY_IN_PROGRESSapplication/json
The first request with this key is still running; retry in a few seconds and the original response is replayed.
429Too many requestsRATE_LIMITEDapplication/json
The token has spent its 300 requests a minute or 10,000 an hour; Retry-After says when the next one is accepted.
curl https://api.subscriby.net/v1/webhook-endpoints/$ENDPOINT_ID \ -H "Authorization: Bearer $SUBSCRIBY_TOKEN"The endpoint and its delivery health. The signing secret is never part of it; it exists in the create and rotate-secret responses only.
disabled_at populates when Subscriby auto-disables an endpoint after too many consecutive failures, or when the creator pauses it. last_success_at / last_failure_at track the most recent delivery outcomes. project_id is null for team-wide endpoints.

Webhook Deliveries API
Every event Subscriby posts to one of your webhook endpoints is a delivery: one row per endpoint per event, carrying the signed envelope that was sent, the target's response and where the row is on the retry ladder.
Webhook Events API
A read-only polling endpoint that surfaces the most recent webhook deliveries for a given event type.
