# View exemption certificate

Learn how to view customers associated with an exemption certificate using the GetCertificate endpoint.

**Element type:** Required

**Endpoints/Models used:** [GetCertificate](https://developer.avalara.com/api-reference/avatax/rest/v2/methods/Certificates/GetCertificate/)

Your integration must allow users to view the customers that are associated with an exemption certificate. Do this by adding an `include=customers` filter in the [GetCertificate](https://developer.avalara.com/api-reference/avatax/rest/v2/methods/Certificates/GetCertificate/) request. Also include your `companyId` and the certificate `id` in the request URL.

**Example**

```
curl
  -X GET
  -H 'Accept: application/json'
  -H 'Authorization: Basic ${btoa(`:`)}'
  -H 'Content-Type: application/json'
  'https://sandbox-rest.avatax.com/api/v2/companies/{companyId}/certificates/{id}?$include=customers'
```
