How to Tiger Another local integration flow when OData response is empty

[itsravi]

Hi All

Need help regarding calling local integration flow .when the response payload is empty

we have scenario where we need to handle the empty response during the get operation of the request reply odata service .

if record not found it should go branch A.and trigger the process call

If record found it should go to the branch B, .

sample flow

For example :

if we query the odata end point using get operation for a filed email id , if the email is exits in the odata system it responds with payload or else a empty payload is returned.

EX:

$select=URI&$filter=URI eq test@gmail.com query.png

sample payload:

if record is found: record.png

If record not found response is empty-record.png

So experts need you help , can some guide me through the steps to achieve the requirement

Thanks

Use below XPATH in the router to check empty response -

//CustomerCollection/exist(Customer) = 'False'

Thanks,
