reactor:update
The Patch Reactors endpoint uses a different content-type to support merge-patch operations. Requests need the Content-Type header to be set to application/merge-patch+json. Requests made with a different Content-Type header value will receive a 415 Unsupported Media Type response code. For more information on merge-patch, see RFC 7386.

Enterprise

Reactor Request Parameters

The reactor will be executed with a req object that contains the following properties

ParameterDescription
argsDetokenized arguments to provided to the reactor.
configurationA key-value map of all configuration name and values defined when creating the Reactor
btA pre-configured Basis Theory JS instance for the application defined with the Reactor. This will be null if no application was defined.

Response

Returns a Reactor Response if the Reactor completed successfully. Returns an error if the Reactor failed. Errors generated from Reactors will be translated to the common Basis Theory Error format. See Reactor Errors for more details.

Reactor Response Object

AttributeTypeDescription
tokensobject(Optional) Token(s) created from the tokenize block of the Reactor code response
rawobject(Optional) Raw output returned from the Reactor

Limitations

Head over to Rate Limits to learn more about Reactors limitations.

Detokenization

In order to use tokenized data within a reactor, the args parameter may contain one or more detokenization expressions. When any detokenization expressions are detected, Basis Theory will attempt to detokenize and inject the raw token data into the args forwarded to the Reactor function.

Reactor request args may contain a mixture of detokenization expressions and raw plaintext data.

Tokens containing complex data may be detokenized into a Reactor request, including Bank and Card token types. When tokens with complex data are detokenized, the entire JSON data payload will be included within the args. For an example, see Use Complex Tokens.

Validation is performed on the resulting request after detokenization, so several required request parameters may be supplied by detokenizing a single complex token that contains several of the request parameters.

At most, 100 tokens may be detokenized within a single Reactor request.

For more detailed examples about how to detokenize within Reactors, check out our Detokenization Examples.

Reactor Object

AttributeTypeDescription
iduuidUnique identifier of the Reactor which can be used to get a Reactor
tenant_iduuidThe Tenant ID which owns the reactor
namestringThe name of the reactor
codestringReactor code which will be executed when the Reactor is processed
configurationmapA key-value map of predefined configuration names and values accessible from the Reactor code
applicationApplication(Optional) This Application's API key is injected into a pre-configured BasisTheory JS SDK instance passed into the Reactor's runtime. Must be a public or private Application Type.
created_byuuid(Optional) The ID of the user or Application that created the Reactor
created_atstring(Optional) Created date of the Reactor in ISO 8601 format
modified_byuuid(Optional) The ID of the user or Application that last modified the Reactor
modified_atdate(Optional) Last modified date of the Reactor in ISO 8601 format

Reactor Code

All Reactor code snippets must export a function which takes in a request object and returns a response object. The snippet should be written in Javascript (targeting Node.js v16) and generally follows the following structure:

module.exports = async function (req) {
const { my_arg } = req.args; // access any args provided with the request
const { MY_CONFIG } = req.configuration; // access any static config defined on the Reactor

// do anything here!

return {
raw: {}, // non-sensitive data that should be returned in plaintext
tokenize: {}, // sensitive data that should be tokenized
};
};

Reactor Code Request Object

AttributeTypeDescription
argsobjectThe arguments that were provided when the reactor was invoked
configurationobjectA key-value map of all configuration name and values defined when creating the Reactor

Reactor Code Response Object

AttributeTypeDescription
rawobject(Optional) Raw output returned from the Reactor
tokenizeobject(Optional) A payload that will be tokenized to produce one or more tokens

The payload returned in the tokenize property will be tokenized in the same way that requests are tokenized via the Tokenize endpoint. For more information, see Tokenize.
