Svix actions 37

Every Svix action below is a callable tool any Definable persona can invoke.

Create Application

Tool to create a new Svix application. Use when you need to register an application with specific settings.

Delete Svix Application

Permanently delete a Svix application by its ID or UID. Use this to remove an application and all its associated endpoints, messages, and webhooks. This action is destructive and cannot be undone.

Get Application

Tool to retrieve details of a specific Svix application by its ID. Use when you need application metadata after authenticating with Svix.

List Applications

Tool to list all applications. Use when you need to retrieve or paginate through your Svix applications.

Update Svix Application

Tool to update an existing Svix application by ID. Use when you need to modify properties like name, rate limit, UID, or metadata. Call after confirming the correct app_id.

Get Attempt Details

Tool to retrieve details of a specific message attempt. Use after confirming app_id, msg_id, and attempt_id.

List Message Attempts

Tool to list all delivery attempts for a specific message. Use after confirming message ID to debug attempts.

Create Endpoint

Tool to create a new Svix webhook endpoint. Use after obtaining the app ID to register your webhook receiver URL.

Delete Endpoint

Tool to delete an endpoint. Use when you need to remove a specific endpoint after confirming its application and endpoint IDs.

Get Endpoint

Tool to retrieve details of a specific endpoint. Use after confirming app_id and endpoint_id.

List Endpoints

Tool to list all endpoints for a specific application. Use after obtaining the application ID to retrieve its endpoints.

Patch Endpoint

Tool to partially update an endpoint’s configuration. Use when you need to adjust endpoint settings without full replacement.

Patch Endpoint Headers

Tool to partially update headers for a specific endpoint. Use when you need to add, modify, or remove custom headers after endpoint creation.

Recover Failed Webhooks

Tool to recover messages that failed to send to an endpoint. Use when you need to retry webhook delivery for failed events after identifying delivery failures.

Replay Missing Webhooks

Tool to replay missing webhooks for a specific endpoint. Use when some webhooks failed or were lost and need to be resent.

Get Endpoint Secret

Tool to retrieve the secret for a specific endpoint. Use after confirming app_id and endpoint_id.

Rotate Endpoint Secret

Tool to rotate the signing secret key for an endpoint. Use when you need to invalidate the current secret and generate or supply a new one. Call after confirming app_id and endpoint_id.

Send Example Message

Tool to send a test message for a specific event type to an endpoint. Use after setting up an endpoint to verify its configuration. Note: the endpoint's filter_types must include the event_type being tested; otherwise real events will not be delivered even if the example message sends successfully.

Get Endpoint Stats

Tool to retrieve basic statistics for a specific endpoint. Use after confirming app_id and endpoint_id.

Get Endpoint Transformation

Tool to retrieve transformation settings for a specific endpoint. Use after confirming app_id and endpoint_id.

Set Endpoint Transformation

Tool to set or update transformation settings for an endpoint. Use when you need to configure or toggle an endpoint's transformation code after creation.

Update Endpoint

Tool to update an existing endpoint or create it if it doesn't exist (upsert). Use when you need to modify endpoint settings like URL, rate limit, channels, or metadata. If the endpoint doesn't exist, a new one will be created with the specified endpoint_id as its uid.

Update Endpoint Headers

Tool to completely replace headers for a specific endpoint. Use when you need to set a full new header mapping.

Create Event Type

Create a new event type in Svix or unarchive an existing one. Event types are identifiers (like 'order.created', 'user.signup') that categorize the webhooks your application sends. Use period-delimited naming to group related events. Both 'name' and 'description' are required. Returns HTTP 409 if the event type already exists.

Delete Event Type

Tool to delete an event type. Use when you need to archive or permanently expunge a specific event type after confirming its name.

Get Event Type

Retrieve details of a specific event type by its name. Use this to inspect an existing event type's configuration, schema, and status. Event types define the categories of events that can be sent through Svix webhooks.

List Event Types

Tool to retrieve a list of all event types. Use when you need to inspect available event types, optionally including their JSON schemas. Use after authenticating the client.

Update Event Type

Update an existing event type's description, schema, feature flags, or archive status. Use this to modify event type configuration. The event type must already exist - use List Event Types or Get Event Type to find valid event type names.

Create Integration

Tool to create a new integration for a specific application. Use after confirming the application ID.

Delete Integration

Permanently delete an integration from a Svix application. This is a destructive operation that cannot be undone. Use when removing webhook integrations that are no longer needed. Requires both the application ID and the integration ID. Use 'List Integrations' first if you need to find the integration_id.

Get Integration

Tool to retrieve details of a specific integration. Use after confirming app_id and integration_id.

List Integrations

Tool to list all integrations for a specific application. Use after confirming the application ID, supporting pagination via limit and iterator. Use when you need to enumerate integrations.

List Messages

Tool to list all messages for a specific application. Use when you need to fetch or paginate messages after obtaining the application ID.

Create Source

Creates a new Svix Ingest source for receiving webhooks from external providers. A source generates an ingest URL that you can share with a webhook provider (e.g., GitHub, Stripe) as the destination for their webhooks. Svix will verify signatures based on the source type and forward the webhooks to your configured endpoints. Use 'genericWebhook' type to skip signature verification for providers not natively supported.

Frequently asked questions

What can I automate with Svix on Definable?

Anything Svix exposes through its API. Common developer tools workflows on Definable include triage issues, review pull requests, monitor builds. Personas can call any of the 37 Svix tools directly, then chain the result into another integration without you writing code.

How does Svix authentication work?

Svix uses API_KEY on Definable. You connect once from the integrations page, scoped to the permissions you choose, and from then on any persona that has the integration enabled can act on your behalf. Tokens are encrypted at rest and rotated automatically.

Is the Svix integration included in my Definable plan?

Yes — every Definable plan, including Starter, includes access to all 37 Svix tools. You only need a separate Svix subscription if Svix itself charges per seat or per API call.

Is using Svix through Definable secure?

Every call from a persona to Svix is logged with the user, persona, prompt, and response. Tokens never leave Definable's secrets vault, scopes are configurable per persona, and you can revoke access at any time from the integration page.

How do I get started with Svix on Definable?

Sign up for Definable, open the integrations page, find Svix, and connect via OAuth or API key. You can immediately attach Svix to any persona and start running workflows. The free Starter plan includes 5,000 credits/month.

What Svix actions does Definable expose?

Definable exposes all 37 Svix actions as callable tools — including `Create Application`, `Delete Svix Application`, `Get Application`, plus 34 more. Each tool gets a typed parameter schema so personas know exactly how to call it.
