# ACCESS SETTINGS

## Retrieve all recent access attempts

**This endpoint allows you to retrieve a list of all of the IP addresses that recently attempted to access your account either through the User Interface or the API.**

IP Access Management allows you to control which IP addresses can be used to access your account, either through the User Interface or the API. There is no limit to the number of IP addresses that you can add to your whitelist. It is possible to remove your own IP address from the whitelist, thus preventing yourself from accessing your account.

For more information, please see our [User Guide](http://sendgrid.com/docs/User_Guide/Settings/ip_access_management.html).

# CAMPAIGNS

## Create a Campaign

**This endpoint allows you to create a campaign.**

Our Marketing Campaigns API lets you create, manage, send, and schedule campaigns.

Note: In order to send or schedule the campaign, you will be required to provide a subject, sender ID, content (we suggest both HTML and plain text), and at least one list or segment ID. This information is not required when you create a campaign.

## Retrieve recipients matching search criteria

**This endpoint allows you to perform a search on all of your Marketing Campaigns recipients.**

* is a variable that is substituted for your actual custom field name from your recipient.

* If field_name is a 'reserved' date field, such as created_at or updated_at, the system will internally convert
your epoch time to a date range encompassing the entire day. For example, an epoch time of 1422835600 converts to
Mon, 02 Feb 2015 00:06:40 GMT, but internally the system will search from Mon, 02 Feb 2015 00:00:00 GMT through
Mon, 02 Feb 2015 23:59:59 GMT.

## Retrieve recipients matching search criteria using segment conditions

**This endpoint allows you to perform a search using segment conditions on all of your Marketing Campaigns recipients.**

Valid operators for search depend on the type of the field you are segmenting:

* **Dates:**
    * "eq", "ne", "lt" (before), "gt" (after)
        * You may use MM/DD/YYYY for day granularity or an epoch for second granularity.
    * "empty", "not_empty"
    * "is within"
        * You may use an ISO 8601 date format or the # of days.
* **Text:** "contains", "eq" (is - matches the full field), "ne" (is not - matches any field where the entire field is not the condition value), "empty", "not_empty"
* **Numbers:** "eq", "lt", "gt", "empty", "not_empty"
* **Email Clicks and Opens:** "eq" (opened), "ne" (not opened)

Field values must all be a string.

Search conditions using "eq" or "ne" for email clicks and opens should provide a "field" of either *clicks.campaign_identifier* or *opens.campaign_identifier*. The condition value should be a string containing the id of a completed campaign.

* **Numbers:** "eq", "lt", "gt", "empty", "not_empty"
* **Email Clicks and Opens:** "eq" (opened), "ne" (not opened)

# MAIL SETTINGS

## Retrieve all mail settings

**This endpoint allows you to retrieve a list of all mail settings.**

Mail settings allow you to tell Twilio Twilio SendGrid specific things to do to every email that you send to your recipients over Twilio SendGrid's [Web API](https://sendgrid.com/docs/API_Reference/Web_API/mail.html) or [SMTP Relay](https://sendgrid.com/docs/API_Reference/SMTP_API/index.html).

### GET /mail_settings


```php
$query_params = json_decode('{"limit": 1, "offset": 1}');
$response = $sg->client->mail_settings()->get(null, $query_params);

print $response->body() . "\n";
print_r($response->headers());
```
## Update address whitelist mail settings

**This endpoint allows you to update your current email address whitelist settings.**

The address whitelist setting whitelists a specified email address or domain for which mail should never be suppressed. For example, you own the domain example.com, and one or more of your recipients use email@example.com addresses, by placing example.com in the address whitelist setting, all bounces, blocks, and unsubscribes logged for that domain will be ignored and sent as if under normal sending conditions.

Mail settings allow you to tell Twilio Twilio SendGrid specific things to do to every email that you send to your recipients over Twilio SendGrid's [Web API](https://sendgrid.com/docs/API_Reference/Web_API/mail.html) or [SMTP Relay](https://sendgrid.com/docs/API_Reference/SMTP_API/index.html).

}');
$response = $sg->client->mail_settings()->address_whitelist()->patch($request_body);

# SENDER AUTHENTICATION

## Create an authenticated domain.

**This endpoint allows you to create a domain authentication for one of your domains.**

If you are creating a domain authentication that you would like a subuser to use, you have two options:
1. Use the "username" parameter. This allows you to create am authenticated subuser. This means the subuser is able to see and modify the created authentication.
2. Use the Association workflow (see Associate Domain section). This allows you to assign a domain authentication created by the parent to a subuser. This means the subuser will default to the assigned domain authentication, but will not be able to see or modify that authentication. However, if the subuser creates their own domain authentication it will overwrite the assigned domain authentication.

A domain authentication allows you to remove the via or sent on behalf of message that your recipients see when they read your emails. Authenticating a domain allows you to replace sendgrid.net with your personal sending domain. You will be required to create a subdomain so that Twilio SendGrid can generate the DNS records which you must give to your host provider. If you choose to use Automated Security, Twilio SendGrid will provide you with 3 CNAME records. If you turn Automated Security off, you will be given 2 TXT records and 1 MX record.

Email link branding allow all of the click-tracked links you send in your emails to include the URL of your domain instead of sendgrid.net.

For more information, please see our [User Guide](https://sendgrid.com/docs/ui/account-and-settings/how-to-set-up-link-branding/).

### POST /whitelabel/links/{id}/validate


```php
$id = "test_url_param";
$response = $sg->client->whitelabel()->links()->_($id)->validate()->post();
print $response->statusCode() . "\n";
print $response->body() . "\n";
print_r($response->headers());
```
## Associate a Link Branding

**This endpoint allows you to associate a link branding with a subuser account.**

Link branding can be associated with subusers from the parent account. This functionality allows
subusers to send mail using their parent's link brands. To associate a link branding, the parent account
must first create a branded link and validate it. The parent may then associate that branded link with a subuser via the API or the Subuser Management page in the user interface.

Email link branding allow all of the click-tracked links you send in your emails to include the URL of your domain instead of sendgrid.net.

For more information, please see our [User Guide](https://sendgrid.com/docs/ui/account-and-settings/how-to-set-up-link-branding/).

### POST /whitelabel/links/{link_id}/subuser


```php
$request_body = json_decode('{
  "username": "jane@example.com"
}');

## Update Event Notification Settings

**This endpoint allows you to update your current event webhook settings.**

If an event type is marked as `true`, then the event webhook will include information about that event.

Twilio SendGrid's Event Webhook will notify a URL of your choice via HTTP POST with information about events that occur as Twilio SendGrid processes your email.

Common uses of this data are to remove unsubscribes, react to spam reports, determine unengaged recipients, identify bounced email addresses, or create advanced analytics of your email program.
