Prerequisites
Before creating a Crunchbase Pro credential, you need to obtain an API user key from your Crunchbase account. The API user key is required to authenticate with the Crunchbase Pro API v4.
To obtain your API user key, you need to have a Crunchbase Pro account with API access enabled. Once you have access to your account, you can generate an API user key from your account settings. The API user key is used to authenticate all API requests to the Crunchbase Pro API v4 using the X-cb-user-key header. For detailed information about API key setup and authentication, refer to the Crunchbase API documentation.
Authenticate
Credentials required
| Field | Required | Secret | Description |
|---|---|---|---|
| API User Key | Yes | Yes | The Crunchbase API uses token-based authentication. Check out the Crunchbase API documentation URL for details on obtaining this key. |
Create a credential in Nexla
- After selecting the data source/destination type, click the Add Credential tile to open the Add New Credential overlay.
New Credential Overlay – Crunchbase Pro

-
Enter a name for the credential in the Credential Name field and a short, meaningful description in the Credential Description field.
-
Enter your Crunchbase Pro API user key in the API User Key field. This is the API user key you obtained from your Crunchbase Pro account settings. The API user key is sent in the
X-cb-user-keyheader to authenticate all API requests to the Crunchbase Pro API v4.Keep your API user key secure and do not share it publicly. The API user key provides access to your Crunchbase Pro account and should be treated as a sensitive credential. The Crunchbase Pro API uses token-based authentication, and the API user key is included in the
X-cb-user-keyheader for all API requests. -
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 Crunchbase Pro connector tile, then select the credential that will be used to connect to the Crunchbase Pro instance, and click Next; or, create a new Crunchbase Pro credential for use in this flow.
Endpoint templates
Nexla provides pre-built templates that can be used to rapidly configure data sources to ingest data from common Crunchbase Pro endpoints. Select the endpoint from which this source will fetch data from the Endpoint pulldown menu. Available endpoint templates are listed in the expandable boxes below. Click on an endpoint to see more information about it and how to configure your data source for this endpoint.
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
Crunchbase Pro data sources can also be manually configured to ingest data from any valid Crunchbase Pro API v4 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.
Crunchbase Pro API endpoints typically follow the pattern https://api.crunchbase.com/api/v4/{endpoint_path} and require API user key authentication in the X-cb-user-key header, which is handled automatically by your credential configuration. The JSON path to data varies by endpoint — for example, $.entities[*] extracts all items from an entities array, $[*] extracts all items from a root-level array, and $ extracts the entire root-level object. For detailed information about available endpoints, see the Crunchbase API documentation.
Once all of the relevant settings have been configured, click the Save button to save and create the new Crunchbase Pro 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.
