# Good to know about Basis

This article gives you tips for building queries and reports that return the data you need, including how the API of this data source handles certain fields and metrics.

If you’re connecting to Basis, follow the instructions in our [connection guide](/v1/docs/basis-connection-guide). See [Basis metrics and dimensions](/v1/docs/basis-fields) for the fields available in this data source.

## Request limits and recommended refresh rate

**Request limit**: 75,000 requests per hour across all endpoints per API user.

**Recommended refresh window**: 2-3 days

## Historical range

There are no known limitations to the historical range of data you can pull with the Basis data source connector.

## Accounts in Basis

In the Basis connector, each Client is considered a separate account within the connection.

Your Supermetrics subscription determines the number of [data source accounts](/v1/docs/about-data-source-accounts) you can use simultaneously.

## Things to consider

### Basis DSP

This connector does not support reporting for customers that only use the Basis DSP product, as it has a different reporting API. We are planning to add support for this in the future.
