Create an Access Code

Create an access code for a device by ID

/access_codes/create

post

Creates a new access code.

Authorizations

client_session_with_customerclient_sessionpat_with_workspaceconsole_session_with_workspaceapi_key

AuthorizationstringRequired

Bearer authentication header of the form Bearer <token>.

Body

application/json

device_idstring · uuidRequired

ID of the device for which you want to create the new access code.

namestringOptional

Name of the new access code. Enables administrators and users to identify the access code easily, especially when there are numerous access codes.

   Note that the name provided on Seam is used to identify the code on Seam and is not necessarily the name that will appear in the lock provider's app or on the device. This is because lock providers may have constraints on names, such as length, uniqueness, or characters that can be used. In addition, some lock providers may break down names into components such as `first_name` and `last_name`.

   To provide a consistent experience, Seam identifies the code on Seam by its name but may modify the name that appears on the lock provider's app or on the device. For example, Seam may add additional characters or truncate the name to meet provider constraints.

   To help your users identify codes set by Seam, Seam provides the name exactly as it appears on the lock provider's app or on the device as a separate property called `appearance`. This is an object with a `name` property and, optionally, `first_name` and `last_name` properties (for providers that break down a name into components).

starts_atstringOptional

Date and time at which the validity of the new access code starts, in ISO 8601 format.

ends_atstringOptional

Date and time at which the validity of the new access code ends, in ISO 8601 format. Must be a time in the future and after starts_at.

codestring · min: 4 · max: 9Optional

Code to be used for access.

Pattern: ^\d+$

syncbooleanOptionalDefault: false

attempt_for_offline_devicebooleanOptionalDefault: true

common_code_keystringOptional

Key to identify access codes that should have the same code. Any two access codes with the same common_code_key are guaranteed to have the same code. See also Creating and Updating Multiple Linked Access Codes.

prefer_native_schedulingbooleanOptional

Indicates whether native scheduling should be used for time-bound codes when supported by the provider. Default: true.

use_backup_access_code_poolbooleanOptional

Indicates whether to use a backup access code pool provided by Seam. If true, you can use /access_codes/pull_backup_access_code.

allow_external_modificationbooleanOptional

Indicates whether external modification of the code is allowed. Default: false.

is_external_modification_allowedbooleanOptional

Indicates whether external modification of the code is allowed. Default: false.

preferred_code_lengthnumber · floatOptional

Preferred code length. Only applicable if you do not specify a code. If the affected device does not support the preferred code length, Seam reverts to using the shortest supported code length.

use_offline_access_codebooleanOptionalDeprecated

is_offline_access_codebooleanOptional

Indicates whether the access code is an offline access code.

is_one_time_usebooleanOptional

Indicates whether the offline access code is a single-use access code.

max_time_roundingstring · enumOptional

Maximum rounding adjustment. To create a daily-bound offline access code for devices that support this feature, set this parameter to 1d.
