v4/domains

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

GET /domains

Parameter Description
authority Filter the list by a given DKIM authority name
state Filter the list by a given state. Can be active, unverified or disabled
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.

PUT /domains/<domain>/verify

Places the domain in an unverified state and triggers the verification process. Returns a single domain, including credentials and DNS records. If the domain is successfully verified the domain’s state will be ‘active’. 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, block, or tag

If disabled, no spam filtering will occur for inbound messages.

If block, inbound spam messages will not be delivered.

If tag, inbound messages will be tagged with a spam header. See Spam Filter.

The default is disabled.

wildcard

true or false

Determines whether the domain will accept email for sub-domains when sending messages.

The default is false.

force_dkim_authority

true or false

If set to true, the domain will be the DKIM authority for itself even if the root domain is registered on the same mailgun account

If set to false, the domain will have the same DKIM authority as the root domain registered on the same mailgun account

The default is false.

dkim_key_size

1024 or 2048

Set the length of your domain’s generated DKIM key

The default is 1024

ips An optional, comma-separated list of IP addresses to be assigned to this domain. If not specified, all dedicated IP addresses on the account will be assigned. If the request cannot be fulfilled (e.g. a requested IP is not assigned to the account, etc), a 400 will be returned.
pool_id The id of the IP Pool that you wish to assign to the domain. The pool must contain at least 1 IP. (Note: IP Pools are only available on certain plans; see http://mailgun.com/pricing)
web_scheme

http or https

Set your open, click and unsubscribe URLs to use http or https

The default is http

PUT /domains/<domain>

Update domain parameters. See examples below.

Parameter Type Description
spam_action String

disabled, block, or tag

If disabled, no spam filtering will occur for inbound messages.

If block, inbound spam messages will not be delivered.

If tag, inbound messages will be tagged with a spam header. See Spam Filter.

The default is disabled.

web_scheme String

http or https

Set your open, click and unsubscribe URLs to use http or https

The default is http

wildcard Boolean

true or false

Determines whether the domain will accept email for sub-domains when sending messages.

DELETE /domains/<domain>

Delete a domain from your account.

POST /domains/<domain>/credentials

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

Parameter Description
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
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.

GET /domains/<domain>/connection

Returns delivery connection settings for the defined domain.

PUT /domains/<domain>/connection

Updates the specified delivery connection settings for the defined domain.

Parameter Description
require_tls

true or false

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 cannot, the message will be delivered over a plaintext SMTP connection.

The default is false.

skip_verification

true or false

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.

PUT /domains/<domain>/tracking/open

Updates the open tracking settings for a domain.

Parameter Description
active yes or no
PUT /domains/<domain>/tracking/click

Updates the click tracking settings for a domain.

Parameter Description
active

yes``or ``no

If set to yes, links will be overwritten and pointed to our servers so we can track clicks.

PUT /domains/<domain>/tracking/unsubscribe

Updates unsubscribe tracking settings for a domain.

Parameter Description
active true or false.
html_footer Custom HTML version of unsubscribe footer.
text_footer

Custom text version of unsubscribe footer.

Mailgun can automatically provide an unsubscribe footer in each email you send and also provides you with several unsubscribe variables. You can customize your unsubscribe footer by editing the settings in the Control Panel. See Open and Click Bot Detection for more details.

PUT /domains/<domain>/dkim_authority

Change the DKIM authority for a domain.

Parameter Description
self

true or false

Change the DKIM authority for a domain.

If set to true, the domain will be the DKIM authority for itself even if the root domain is registered on the same mailgun account

If set to false, the domain will have the same DKIM authority as the root domain registered on the same mailgun account

Note

Use with caution: Do not forget to change the corresponding DNS record. It can take 24-48 hours for DNS changes to propagate. Changing the DKIM authority of an active domain affects its current deliverability.

Update the DKIM selector for a domains

PUT /domains/<domain>/dkim_selector
Parameter Description
dkim_selector change the DKIM selector for a domain.

Update the CNAME used for tracking opens and clicks

PUT /domains/<domain>/web_prefix
Parameter Description
web_prefix change the tracking CNAME for a domain.
