URI Parameters
Parameter | Required | Type | Default | Description |
---|---|---|---|---|
id | true | uuid | null | The ID of the Reactor |
Request Parameters
Parameter | Required | Type | Default | Description |
---|---|---|---|---|
args | false | object | null | Arguments to provide to the reactor. |
callback_url | false | string | null | Indicates that the reactor should be invoked asynchronously and the result delivered as a webhook to this URL. See Asynchronous Reactors for more info. Enterprise DEPRECATED |
Reactor Request Parameters
The reactor will be executed with a req
object that contains the following properties
Parameter | Description |
---|---|
args | Detokenized arguments to provided to the reactor. |
configuration | A string key and string value map of all configuration name and values defined when creating the Reactor |
bt | A 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 Error Codes below for more details.
Reactor Response Object
Attribute | Type | Description |
---|---|---|
tokens | object | (Optional) Token(s) created from the tokenize block of the Reactor code response |
raw | object | (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.
Reactor Error Codes
Code | Meaning | Common Scenarios |
---|---|---|
400 | Bad Request |
|
401 | Authentication Error |
|
402 | Invalid Payment Method |
|
422 | Unprocessable Entity |
|
429 | Rate Limit Error |
|
500 | Reactor Runtime Error |
|
There are a few different root causes for why one of these errors may be returned from a reactor:
-
An error occurred within Basis Theory's reactor execution framework when processing your request. For example, this can occur if the reactor code is invalid and fails to compile (JavaScript code is validated before being executed) resulting in a
422
error, or if the providedargs
contain an invalid expression resulting in a400
error. -
An error occurred within your reactor code. For example, an HTTP call is made to an external API and they responded with an error, or a runtime error occurred within the code due to a bug. The following section details best practices when handling errors within reactor code.
