# Check offers went to one person once

GET

/v1/addresses/{address}/offers

```js
const url = 'https://api.proxymail.qa/v1/addresses/k7f2x9ab12cd%40mailclub.dev/offers';
const options = {
  method: 'GET',
  headers: {
    'Proxy-Mail-QA-Test': 'sign-up%20%E2%80%BA%20sends%20one%20code',
    Authorization: 'Bearer <token>'
  }
};

try {
  const response = await fetch(url, options);
  const data = await response.json();
  console.log(data);
} catch (error) {
  console.error(error);
}
```

```sh
curl --request GET \
  --url https://api.proxymail.qa/v1/addresses/k7f2x9ab12cd%40mailclub.dev/offers \
  --header 'Authorization: Bearer <token>' \
  --header 'Proxy-Mail-QA-Test: sign-up%20%E2%80%BA%20sends%20one%20code'
```

For each sender, its coupons at this address and which version of the address each went to: `plain`, `capitals` or a `+tag`. Mail to all of them reaches one inbox, so an offer that reached two or more versions was given to one person more than once: `reused` is true, `passed` false, and with a run, that fails it. Gmail’s dot trick can’t be tested here: on these domains a dot makes another address. In Labs: answers 403 until the key’s creator switches on Marketing and offer emails in Account settings → Labs.

## Parameters

### Path Parameters

**address**

required

string format: email

The test address, URL-encoded. A variant also works: capitals, or a +tag (k7f2x9ab12cd+o’[brien@mailclub.dev](mailto:brien@mailclub.dev)). It acts on the plain address; waiting on a +tag variant, or listing its messages, only finds mail sent to that variant.

#### Example 

```plaintext
k7f2x9ab12cd@mailclub.dev
```

### Header Parameters

**Proxy-Mail-QA-Run**

string format: uuid

A run’s id (POST /v1/runs): adds what this call saw to the run. If it can’t be added (the run finished, or isn’t in this project), the call still works and the Proxy-Mail-QA-Run-Warning response header says why.

**Proxy-Mail-QA-Test**

string

<= 600 characters

With Proxy-Mail-QA-Run: the test this call belongs to, percent-encoded (encodeURIComponent), up to 200 characters once decoded. The run’s report shows it beside what the call saw.

#### Example 

```plaintext
sign-up%20%E2%80%BA%20sends%20one%20code
```
