To connect Nexla to Finnhub, you will need a Finnhub API key. Finnhub provides a free tier that includes 60 API calls per minute, real-time US stock quotes, company news, basic fundamentals, and more. Paid plans are available for higher rate limits and additional data coverage.
Your API key is displayed directly on the dashboard. Copy this key — it will be entered into Nexla during credential setup.
Your Finnhub API key grants access to all endpoints permitted by your plan tier. Treat your API key as a secret — do not share it publicly or commit it to source control. If your key is compromised, you can regenerate it from the Finnhub dashboard.
Finnhub enforces rate limits based on your subscription plan. The free tier allows 60 API calls per minute. For high-volume or real-time data use cases, review Finnhub's pricing page to determine the plan that best fits your needs.
To create a new Finnhub credential, after selecting the data source type, click the Add Credential tile to open the Add New Credential overlay.
Enter a name for the credential in the Credential Name field and a short, meaningful description in the Credential Description field.
Enter your Finnhub API key in the API Key Value field. This is the key you copied from the Finnhub dashboard in Prerequisites. The key is a unique alphanumeric string that identifies your account and authorizes access to the Finnhub API. Finnhub uses API key authentication, and the key is passed as the X-Finnhub-Token HTTP request header on every API call Nexla makes to the Finnhub API.
The API key is stored securely and is used by Nexla to authenticate all requests sent to the Finnhub API on your behalf. Nexla automatically includes the key as the X-Finnhub-Token header, so no additional configuration is needed.
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 creation and can be selected for use with a new data source.
To create a new data flow, navigate to the Integrate section, and click the New Data Flow button. Select the Finnhub connector tile, then select the credential that will be used to connect to the Finnhub instance, and click Next; or, create a new Finnhub credential for use in this flow.

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.
Finnhub data sources can also be manually configured to ingest data from any valid Finnhub API endpoint, including endpoints not covered by the pre-built templates, chained API calls, or sources that require custom date range parameters or additional query string values. 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 (GET for all Finnhub endpoints), endpoint URL, date/time and lookup macros, path to data, metadata, and request headers.
All Finnhub API endpoints use the base URL https://finnhub.io/api/v1/ followed by the endpoint path and query parameters. The Finnhub API key is automatically included in requests via the credential configured for this source — you do not need to append it manually to the URL or add the X-Finnhub-Token header yourself. Date/time macros are particularly useful for endpoints that accept from/to date range parameters (most Finnhub date fields use YYYY-MM-DD format), and many endpoints nest their data under a top-level key rather than returning a bare array — for example, $.data[*], $.earningsCalendar[*], $.ipoCalendar[*], or $.constituents[*]. For the complete list of Finnhub endpoints and their URL formats, see the Finnhub API documentation.
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 Finnhub 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.
