VWO

VWO (Visual Website Optimizer) is a conversion optimization platform providing A/B testing, multivariate testing, and personalization. Its REST APIs expose account, user, campaign, and feature-flag resources, letting you read experimentation data into Nexla and manage feature flags programmatically.

Power end-to-end data operations for your VWO API with Nexla. Our bi-directional VWO connector is purpose-built for VWO, 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 VWO or any other destination. With comprehensive monitoring, lineage tracking, and access controls, Nexla keeps your VWO workflows fast, secure, and fully governed.

Prerequisites

Before creating a VWO credential, you need a VWO account with API access and an API token. VWO authenticates every API request with a token sent as a Bearer token in the Authorization header. API token access is available on VWO's Enterprise plan.

To obtain your VWO API token, follow these steps:

1. Sign in to your VWO account at app.vwo.com using your account credentials.

2. Open the developer tokens page at app.vwo.com/#/developers/tokens.

3. Generate a new API token, selecting the permission level (read or read/write) appropriate for how you intend to use the connector in Nexla.

4. Copy the generated token and store it securely. The token is not time-bound and remains valid until it is revoked.

The token authenticates your requests and grants access to VWO resources based on the permission level you selected. The Base URL for the VWO API is used to construct request endpoints. If your token is compromised, revoke it from the developer tokens page and generate a new one. For detailed information about VWO API authentication and available endpoints, see the VWO Developer Documentation.

Authenticate

Credentials required

Authenticate using VWO API key passed as Bearer token in Authorization header.

Field	Required	Secret	Description
API Key	Yes	Yes	VWO account API key for authentication.
Base URL	Yes	No	The base URL for the VWO API.

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 VWO API token in the API Key field. This token is sent as a Bearer token in the Authorization header for all API requests and must be kept confidential.

4. Enter the Base URL for the VWO API. This is used to construct the endpoint URLs for your requests.

   If your API token is compromised, revoke it from the VWO developer tokens page and generate a new one. The token grants access to your VWO account data based on its assigned permission level and should be treated as sensitive information.

   For detailed information about VWO API authentication, permissions, and available endpoints, see the VWO Developer Documentation.

5. 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 VWO connector tile, then select the credential that will be used to connect to VWO, and click Next; or, create a new VWO credential for use in this flow.
