Batch Execution in APIM

Question

I have created a API which is masking the url of backend service.
The BE API is REST API and is expecting a batch execution.

Ex - The request coming from FE - https://abc.pqr.com:443/$batch - POST operation
This request would have payload like

1. GET EntityA Http /1.1
2. GET EntityA Http /1.1
3. POST EntityA Http /1.1

APIM url - https://azure-api.com:443/resource - masked url and will send the payload.

But I want to add a check that if the payload has all GET method then only allow request to be sent to BE or else if it has any other method like PUT, POST then error out the request and do not send to BE.

In APIM how do i achieve this using policy.

@Suresh Thakur, Kirti You could perform a validation by checking the contents of the request body using policy expresions and then leverage the choose policy to return a response in case the request body isn't as required or forward the request as usual.
