Tools

Get Endpoint Headers

Retrieve the custom HTTP headers configured for a webhook endpoint, including the names of sensitive headers that Svix redacts.

Create Application

Create a new consumer application in Svix. Applications represent your customers and are the target for webhook messages. Assign a custom UID (e.g., your internal customer ID) to enable stateless usage without storing Svix IDs.

Create Endpoint

Create a new webhook endpoint for an application. Endpoints are target URLs that receive webhook messages. Configure event type filtering, channels, and custom headers.

Precheck Message

Check whether a message with the given event type and channels would be sent to any active endpoint before creating it.

Get Application

Retrieve details of a specific consumer application by ID or UID. Returns the application's name, metadata, rate limit, and timestamps.

Recover Failed Messages

Bulk-recover all failed messages for an endpoint since a given date. This resends all messages that have exhausted their retry attempts. Use this after an outage or endpoint misconfiguration to replay missed webhooks.

Get Endpoint Stats

Get delivery statistics for a specific endpoint including counts of successful, pending, failed, and sending attempts. Also retrieves the endpoint's signing secret for webhook verification.

Delete Application

Permanently delete a consumer application and all its associated endpoints and messages. This action cannot be undone.

Get Endpoint Transformation

Retrieve the JavaScript transformation configured for an endpoint and whether it is enabled.

Update Application

Update an existing consumer application's name, UID, rate limit, or metadata. Provide the application ID or UID to identify which application to update.

List Event Types

List registered event types in your Svix environment. Event types categorize webhook messages and allow consumers to subscribe to specific events.

Expunge Message Content

Delete the stored payload for a message while preserving delivery metadata. Use this for retention and privacy workflows.

Send Message

Send a webhook message to a specific application. The message will be dispatched to all matching endpoints of that application. Optionally auto-create the application if it doesn't exist by including application details.

Get Message

Retrieve a webhook message by Svix message ID or event ID. Optionally include the payload content for debugging or audit workflows.

List Attempts by Endpoint

List delivery attempts targeting a specific endpoint across all messages. Useful for diagnosing endpoint health and delivery patterns.

Rotate Endpoint Secret

Rotate an endpoint's webhook signing secret. Provide a specific secret or omit it to let Svix generate one.

Get Endpoint

Retrieve a webhook endpoint's URL, filtering, throttle, status, metadata, and timestamps by ID or UID.

List Attempts by Message

List delivery attempts for a specific message. Shows the status, response, and endpoint for each attempt. Use this to debug delivery failures or verify successful delivery.

Delete Event Type

Archive (soft-delete) an event type. Archived event types are hidden from consumers but can still be referenced by existing messages.

Update Endpoint Transformation

Set, unset, enable, or disable the JavaScript transformation associated with an endpoint.

Get Event Type

Retrieve an event type by name, including schemas, feature flags, grouping, and lifecycle state.

Get Endpoint Secret

Retrieve an endpoint's webhook signing secret for signature verification.

Get Portal Access

Generate a short-lived App Portal URL for a specific application. The portal lets your customers manage their endpoints, debug delivery, and inspect/replay past webhooks — all without needing a Svix account.

Update Endpoint

Update an existing webhook endpoint's URL, event type filters, channels, rate limit, or other configuration.

Import Event Types from Open API

Create or update Svix event types from an OpenAPI document's webhooks section. Supports dry runs to preview changes without modifying event types.

List Applications

List consumer applications in your Svix environment. Applications represent your customers, each receiving their own webhook messages. Use this to browse or search for applications before managing their endpoints or messages.

List Endpoints

List all webhook endpoints for a specific application. Returns endpoint URLs, filtering configuration, and status.

List Messages

List webhook messages sent to an application. Filter by event type, channel, or time range. Use this to audit message history or debug delivery issues.

Delete Endpoint

Permanently delete a webhook endpoint from an application. The endpoint will no longer receive messages.

Update Endpoint Headers

Replace the custom HTTP headers sent with webhook deliveries for an endpoint.

Update Event Type

Update an event type's description, schemas, archive/deprecation state, feature flags, or group name.

Create Event Type

Register a new event type in Svix. Event types are the primary way for webhook consumers to configure which events they receive. Optionally include a JSONSchema (Draft 7) to define the expected payload shape.

Resend Message

Manually resend a specific message to a specific endpoint. Use this to retry a single failed delivery without recovering all messages.
