Sidecar Preprocess POST Request Call To Lambda Function with Client Request (Specifications)

Sidecar to Lambda Function Connection

Field	Required Field Yes/No	Type	Description/Value	Example	Notes
`region`	Yes	string	AWS region where Lambda function is hosted.	`region: eu-west-1`
`functionARN`	Yes	string	AWS ARN to make Lambda function invocation.	`functionARN: arn:aws:lambda:eu-west-1:190954361614:function:LambdaBasicAsync`
`roleARN`	Yes	string	Role ARN which needs to be used for generating assume role credentials.	`roleARN:arn:aws:sts::680833432085:role/tibco_sidecar_connector_fn1`	Role Name must begin with `"tibco_sidecar_connector"`
`externalIdKey`	Yes	string	`ExternalID` specified in trust policy of role in IAM will be stored in AWS Parameter Store using Key and Value pair. Key for External ID needs to be specified in this parameter. Using this key, value for External ID will be retrieved from AWS Parameter Store.	`externalIdKey :tibco/prod/trustKey`	Inclusion of external ID strengthen security of AWS Lambda invocation. As external ID is secure parameter, it is stored in the AWS Parameter Store using secure string. This external ID specified in the trust policy of role which we want to assume in IAM. For successful generation of assume role credentials, this external ID must be sent to AWS Lambda. Please make sure that this external ID is present in all regions of Boomi AWS Parameter Store.
`sessionName`	No	string	AWS Lambda session through assume role is created with this name.	`sessionName:assume-role-lambda-access-poc`	If not specified, session name will be specified in the AWS Lambda Request as `"TIBCO_Mashery_SideCar_Connector"`
`expirationDuration`	No	integer	Assume Role credentials expiration duration in minutes.	`expirationDuration:15`	Default value: 60 minutes.

Supported Optional Configurations

Field	Required Field Yes/No	Type	Description/Value	Example	Notes
`synchronicity`	No	string	This parameter specifies whether request sent to AWS Lambda should be synchronously or asynchronously. If AWS Lambda function needs to be invoked synchronously, then its value should be request-response. If AWS Lambda function needs to be invoked asynchronously, then its value should be Event.	`synchronicity:request-response`	Possible values for `synchronicity`: `request-response`, `event`. Default value: `request-response`
`include-response-headers`	No	string	Specifies API client response headers to be included in the lambda sidecar input.
`skip-response-headers`	No	string	Specifies API client response headers to be skipped in the lambda sidecar input. This option is mutually exclusive with `include-response-headers`.
`require-eavs`	No	string	Specifies the mandatory application EAVs that must be set to a non-empty value before the request can be handled. These values are also included in the lambda sidecar input.	`require-eavs: eav_1,eav_2,eav_3`	The EAVs ARE case-sensitive, and must be included exactly as they are known in Cloud API Management. All Application level EAVs configured must be present and set in Cloud API Management, otherwise block the call.
`include-eavs`	No	string	Specifies the application EAVs to be included in the Lambda function input, if they are present.
`require-packageKey-eavs`	No	string	Specifies the mandatory package key EAVs that must be set to a non-empty value before the request can be handled. These values are also included in the lambda sidecar input.		All Package Key EAVs configured must be present and set in Cloud API Management, otherwise block the call.
`include-packageKey-eavs`	No	string	Specifies the package key EAVs to be included in the Lambda function input, if they are present.
`max-payload-size`	No	string	Max payload size that can be sent to Lambda function in KB.	`max-payload-size: 50`	Default value: 10 Max is 1024 KB (1 MB).

`expand-input`	No	string	Specifies what other values need to be included while sending request to Lambda function, such as `requestPayload`, `remoteAddress`, `token`, `operation`, `routing`.	`expand-input: requestPayload, operation`
`sidecar-param-<parameter name>`	No	string	In case parameter map needs to be sent to AWS Lambda request, define multiple parameters in the format `sidecar-param-<parameter_name>:<parameter_value>`.	`sidecar-param-parameter_x:This is string` `sidecar-param-parameter_y:true` `sidecar-param-parameter_z:1234`	Sidecar policy validates whether parameter value is string, boolean, integer or float, and adds that parameter to the request payload sent to AWS Lambda function. The following parameter map will be added in the request JSON sent to AWS Lambda function: `{"params":{"parameter_x":"This is string", "parameter_y":true, "parameter_z":1234}}`
`failSafe`	No	boolean	Specifies whether failure of Lambda function should result in error or not. If `failSafe` is not specified and the lambda function throws an error, then error will be sent to client.	`failSafe: true`	Default value: `false`
`enable_error_set`	No	boolean	Specifies whether error code and error message sent by policy should be overridden by defined error sets.	`enable_error_set: true`	Default value: `false`
`timeout`	No	integer	Specifies timeout for Lambda function in milliseconds.	`timeout : 500`	If timeout parameter is not specified, timeout will occur according to endpoint timeout. Sum of timeout specified in pre and post input configuration should be less than endpoint timeout. In case of timeout, `504_Gateway_Timeout` error will occur.
