Lambdas

Overview

This API has been available since 1.6.0

Lambdas are user defined JavaScript functions that may be executed at runtime to perform various functions. Lambdas may be used to customize the claims returned in a JWT, reconcile a SAML v2 response or an OpenID Connect response when using these external identity providers.

Search for Lambdas

This API has been available since 1.45.0

This API is used to search for Lambdas and may be called using the GET or POST HTTP methods. Examples of each are provided below. The POST method is provided to allow for a richer request object without worrying about exceeding the maximum length of a URL. Calling this API with either the GET or POST HTTP method will provide the same search results given the same query parameters.

Request

API Key Authentication
Search for Lambdas
GET /api/lambda/search ?body={body}&name={name}&type={type}

Request Parameters

bodyString

The case-insensitive string to search for in the Lambda function body. This can contain wildcards using the asterisk character (*). If no wildcards are present, the search criteria will be interpreted as *value*.

nameString

The case-insensitive string to search for in the Lambda name. This can contain wildcards using the asterisk character (*). If no wildcards are present, the search criteria will be interpreted as *value*.

numberOfResultsIntegerDefaults to 25

The number of results to return from the search.

orderByStringDefaults to name ASC

  • name - the Lambda name
  • engineType - the JavaScript execution engine for the Lambda
    • GraalJS
    • Nashorn

The order direction is optional. Possible values of the order direction are ASC or DESC. If omitted, the default sort order is ASC.

For example, to order the results by the insert instant in a descending order, use insertInstant DESC.

startRowIntegerDefaults to 0

The offset into the total results. In order to paginate the results, increment this value by the numberOfResults for subsequent requests.

For example, if the total search results are greater than the page size designated by numberOfResults , set this value to 25 to retrieve results 26-50, assuming the default page size.

Update a Lambda

This API is used to update an existing Lambda.

You must specify all of the properties of the Lambda when calling this API with the PUT HTTP method. When used with PUT, this API doesn’t merge the existing Lambda and your new data. It replaces the existing Lambda with your new data.

Utilize the PATCH HTTP method to send specific changes to merge into an existing Lambda.

The lambda type may not be changed.

API Key Authentication
Update the Lambda with the given Id
PUT /api/lambda/{lambdaId}
PATCH /api/lambda/{lambdaId}

When using the PATCH method, you can either use the same request body documentation that is provided for the PUT request for backward compatibility. Or you may use either JSON Patch/RFC 6902] or JSON Merge Patch/RFC 7396. See the PATCH documentation for more information.

When using the PATCH method with a Content-Type of application/json the provided request parameters will be merged into the existing object, this means all parameters are optional when using the PATCH method and you only provide the values you want changed. A null value can be used to remove a value. Patching an Array will result in all values from the new list being appended to the existing list, this is a known limitation to the current implementation of PATCH.
