Core API/Methods

Methods are used to execute actions and request data back from the API.

Launching

launch

Emulate the scanning of a token.

Parameters

Accepts two types of parameters:

• A string, in which case the string will be treated as the token text with all other options set as default.
• An object:

Key	Type	Required	Description
type	string	No	An internal category of the type of token being scanned. Not currently in use outside of logging.
uid	string	No*	The UID of the token being scanned. For example, the UID of an NFC tag. Used for matching mappings.
text	string	No*	The main text to be processed from a scan, should contain TapScript.
data	string	No*	The raw data read from a token, converted to a hexadecimal string. Used in mappings and detection of NFC toys.

These parameters allow emulating a token exactly as it would be read directly from an attached reader on the server. A request's parameters must contain at least a populated uid, text or data value.

Result

Returns null on success.

Currently, it is not reported if the launched TapScript encountered an error during launching, and the method will return before execution of TapScript is complete.

Mappings

Mappings are used to modify the contents of tokens before they're launched, based on different types of matching parameters. Stored mappings are queried before every launch and applied to the token if there's a match. This allows, for example, adding TapScript to a read-only NFC tag based on its UID.

mappings

List all mappings.

Returns a list of all active and inactive mappings entries stored on server.

Parameters

None.

Result

Key	Type	Required	Description
mappings	Mapping[]	Yes	List of all stored mappings. See mapping object.

Mapping object

Key	Type	Required	Description
added	string	Yes	Timestamp of the time mapping was created in RFC3339 format.
enabled	boolean	Yes	True if the mapping will be used when looking up matching mappings.
id	number	Yes	Internal database ID of mapping entry. Used to reference mapping for updates and deletions.
label	string	No	An optional display name shown to the user.
type	string	Yes	The method used to match a mapping pattern: exact: match the entire string exactly to the field. partial: match part of the string to the field. regex: use a regular expression to match the field.
match	string	Yes	The field which will be matched against: uid: match on UID, if available. UIDs are normalized before matching to remove spaces, colons and convert to lowercase. text: match on the stored text on token. data: match on the raw token data, if available. This is converted from bytes to a hexadecimal string and should be matched as this.
pattern	string	Yes	Pattern that will be matched against the token, using the above settings.
override	string	Yes	Final text that will completely replace the existing token text if a match was successful.
