# Access Your Customer Data

Once Your Customer has successfully completed the Onboarding Flow and granted Consent so that you, as The Client, can access their data, their Consent status will have changed.

You can then use the Consent ID when calling API.1 to retrieve data from Your Customer's Accounting System.

**What you need for each request:** the Consent ID and the API Key you created in the Client Portal. Use them to access any API.1 endpoint and filter or list invoices. Accounting API requests are scoped by Consent: the Consent ID is included in the request path (for example `.../consents/{consentId}/...`). See the [API Reference](https://apidocs.zwapgrid.com/) for the exact URL structure.

For full endpoint details, see the [API Reference](https://apidocs.zwapgrid.com/) section of our documentation.
