# View exemption certificate

**Element type: Required**

**Endpoints 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. This can be done by adding an`include=customers` filter in the [GetCertificate](https://developer.avalara.com/api-reference/avatax/rest/v2/methods/Certificates/GetCertificate/) request. You must also include your`companyId` and the certificate`Id` in the request URL.

```
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'
```
