Domains

This API allows you to create, access, and validate domains programmatically.

GET /domains

Returns a list of domains under your account in JSON. See examples below.

Parameter	Description
limit	Maximum number of records to return. (100 by default)
skip	Number of records to skip. (0 by default)

GET /domains/<domain>

Returns a single domain, including credentials and DNS records. See examples below.

Parameter	Description
name	Name of the domain

PUT /domains/<domain>/verify

Verifies and returns a single domain, including credentials and DNS records. If the domain is successfully verified the message should be the following: Domain DNS records have been updated. For more information on verifying domains, visit the Mailgun User Manual.

POST /domains

Create a new domain. See examples below.

Parameter	Description
name	Name of the domain (ex. domain.com)
smtp_password	Password for SMTP authentication
spam_action	disabled or tag Disable, no spam filtering will occur for inbound messages. Tag, messages will be tagged with a spam header. See Spam Filter.
wildcard	true or false Determines whether the domain will accept email for sub-domains.

DELETE /domains/<domain>

Delete a domain from your account.

Parameter	Description
name	Name of the domain

GET /domains/<domain>/credentials

Returns a list of SMTP credentials for the defined domain.

Parameter	Description
name	Name of the domain
limit	Maximum number of records to return. (100 by default)
skip	Number of records to skip. (0 by default)

POST /domains/<domain>/credentials

Creates a new set of SMTP credentials for the defined domain.

Parameter	Description
name	Name of the domain
login	The user name, for example bob.bar
password	A password for the SMTP credentials. (Length Min 5, Max 32)

PUT /domains/<domain>/credentials/<login>

Updates the specified SMTP credentials. Currently only the password can be changed.

Parameter	Description
name	Name of the domain
login	The user name, for example bob.bar
password	A password for the SMTP credentials. (Length Min 5, Max 32)

DELETE /domains/<domain>/credentials/<login>

Deletes the defined SMTP credentials.

Note

Mailgun imposes a rate limit for the Domains API endpoint. Users may issue no more than 300 requests per minute, per account. See the resultant rate limit response below.

Parameter	Description
name	Name of the domain
login	The user name, for example bob.bar

GET /domains/<domain>/connection

Returns delivery connection settings for the defined domain.

Parameter	Description
name	Name of the domain

PUT /domains/<domain>/connection

Updates the specified delivery connection settings for the defined domain.

Parameter	Description
require_tls	If set to True this requires the message only be sent over a TLS connection. If a TLS connection can not be established, Mailgun will not deliver the message. If set to False, Mailgun will still try and upgrade the connection, but if Mailgun can not, the message will be delivered over a plaintext SMTP connection. The default is False.
skip_verification	If set to True, the certificate and hostname will not be verified when trying to establish a TLS connection and Mailgun will accept any certificate during delivery. If set to False, Mailgun will verify the certificate and hostname. If either one can not be verified, a TLS connection will not be established. The default is False.

GET /domains/<domain>/tracking

Returns tracking settings for a domain.

Parameter	Description
name	Name of the domain (ex. domain.com)

PUT /domains/<domain>/tracking/open

Updates the open tracking settings for a domain.

Parameter	Description
name	Name of the domain (ex. domain.com)

PUT /domains/<domain>/tracking/click

Updates the click tracking settings for a domain.

Parameter	Description
name	Name of the domain (ex. domain.com)

PUT /domains/<domain>/tracking/unsubscribe

Updates unsubscribe tracking settings for a domain.

Parameter	Description
name	Name of the domain (ex. domain.com)
