Svix

Svix is an enterprise-ready webhooks service that lets applications send webhook messages to their users' endpoints reliably and at scale. It manages applications, endpoints, event types, messages, and delivery attempts, handling retries, signature verification, and delivery monitoring on your behalf. This connector uses the Svix REST API to read webhook infrastructure and delivery data into Nexla, and to create applications, endpoints, event types, and messages.

Power end-to-end data operations for your Svix API with Nexla. Our bi-directional Svix connector is purpose-built for Svix, making it simple to ingest data, sync it across systems, and deliver it anywhere — all with no coding required. Nexla turns API-sourced data into ready-to-use, reusable data products and makes it easy to send data to Svix or any other destination. With comprehensive monitoring, lineage tracking, and access controls, Nexla keeps your Svix workflows fast, secure, and fully governed.

Prerequisites

Before creating a Svix credential, you need a Svix account and an API key. Svix authenticates every API request with a bearer token, sent in the Authorization header as Bearer <your-api-key>.

To obtain your Svix API key, follow these steps:

1. Sign in to the Svix Dashboard.

2. Open the API Access page.

3. Copy the API key for the environment you want to connect. Svix issues a separate API key per environment, and every organization starts with a development environment key that is intended only for development and internal testing, not for production systems.

Svix serves several regions from distinct API hosts. The endpoint templates in this connector target the EU region host (api.eu.svix.com), so use an API key issued for your EU environment. Treat your API key like a password, since it can make any API call on behalf of your account. Svix lets you create multiple keys per environment and set expiration dates, which supports rotating keys without downtime. For more detail, see the Svix API keys documentation and the Svix API reference.

Credentials required

Field	Required	Secret	Description
API Key	Yes	Yes	API key.

Create a credential in Nexla

1. After selecting the data source/destination type, click the Add Credential tile to open the Add New Credential overlay.

2. Enter a name for the credential in the Credential Name field and a short, meaningful description in the Credential Description field.

3. Enter your Svix API key in the API Key field. This key is sent as a bearer token in the Authorization header for all requests to the Svix API and must be kept confidential.

   If your API key is compromised, revoke it from the API Access page in the Svix Dashboard and issue a new one. Because keys are scoped per environment, make sure the key you enter belongs to the environment and region you intend to connect.

4. Click the Save button at the bottom of the overlay. The newly added credential will now appear in a tile on the Authenticate screen during data source/destination creation.

Use as a data source

To create a new data flow, navigate to the Integrate section, and click the New Data Flow button. Select the Svix connector tile, then select the credential that will be used to connect to Svix, and click Next; or, create a new Svix credential for use in this flow.

Endpoint templates

Once the selected endpoint template has been configured, click the Test button to the right of the endpoint selection menu to retrieve a sample of the data that will be fetched. Sample data will be displayed in the Endpoint Test Result panel on the right, allowing you to verify that the source is configured correctly before saving.

Manual configuration

Svix data sources can also be manually configured to ingest data from any valid Svix API endpoint, including endpoints not covered by the pre-built templates, chained API calls, or custom request parameters. Select the Advanced tab at the top of the configuration screen, and follow the instructions in Connect to Any API to configure the API method, endpoint URL, date/time and lookup macros, path to data, metadata, and request headers.

Once all of the relevant settings have been configured, click the Create button in the upper right corner of the screen to save and create the new Svix data source. Nexla will now begin ingesting data from the configured endpoint and will organize any data that it finds into one or more Nexsets.

Use as a destination

Click the + icon on the Nexset that will be sent to the Svix destination, and select the Send to Destination option from the menu. Select the Svix connector from the list of available destination connectors, then select the credential that will be used to connect to Svix, and click Next; or, create a new Svix credential for use in this flow.

Endpoint templates

Nexla provides pre-built templates that can be used to rapidly configure destinations to send data to common Svix endpoints. Select the endpoint to which data will be sent from the Endpoint pulldown menu. Then, click on the template in the list below to expand it, and follow the instructions to configure additional endpoint settings.

[Rest API] Create Application

Create a new application (consumer app) to send webhooks to. Each record from your Nexset is sent as a separate request to create an application.

• Send the application payload as JSON in the request body, in the format expected by the Svix API.

[Rest API] Create Message

Send a webhook message to all endpoints subscribed to the application. Each record from your Nexset is sent as a separate request to create a message.

• Requires an Application ID to identify which application will send the message.
• Send the message payload as JSON in the request body, in the format expected by the Svix API.

[Rest API] Create Endpoint

Create a new endpoint to receive webhook messages for an application. Each record from your Nexset is sent as a separate request to create an endpoint.

• Requires an Application ID to identify which application the endpoint belongs to.
• Send the endpoint payload as JSON in the request body, in the format expected by the Svix API.

[Rest API] Create Event Type

Create or update an event type definition. Each record from your Nexset is sent as a separate request to create or update an event type.

• Send the event type payload as JSON in the request body, in the format expected by the Svix API.

[Rest API] Delete Application

Delete an existing application by its ID. Each record from your Nexset triggers a separate request to delete an application.

• Requires an Application ID to identify which application to delete.

Deleting an application permanently removes it and its associated endpoints and messages in Svix. Confirm the Application IDs in your Nexset before activating this destination.

Manual configuration

Svix destinations can also be manually configured to send data to any valid Svix API endpoint. Select the Advanced tab at the top of the configuration screen, and follow the instructions in Connect to Any API to configure the API method, data format, endpoint URL, request headers, attribute exclusions, record batching, and response webhooks.

Svix APIs expect JSON payloads for create operations. Ensure each Nexset record matches the request body structure documented in the Svix API reference for the endpoint you are targeting.

Save & activate

Once all endpoint settings have been configured, click the Done button in the upper right corner of the screen to save and create the destination. To send the data to the configured Svix endpoint, open the destination resource menu, and select Activate.

The Nexset data will not be sent to the Svix endpoint until the destination is activated. Destinations can be activated immediately or at a later time, providing full control over data movement.
