Retry Mechanism in APIGEE API

[#1]

I am trying to call backend service. I have to handle a situation in which if I will get the INVALID_SESSION_ID fault from backend service I need to call the backend service with new Session ID. is it possible to call the backend service again in such scanario if yes, how to do it.

Pls check this link http://apigee.com/docs/api-services/cookbook/implementing-http-clients-javascript

You can use javascript to make http calls .

waitForComplete() on first send and based on the response you can take necessary action .

Thanks. It helped me a bit.

However is there any pointers how to send the SOAP request and parse it using the java script code.

If you can share similar code for Java as well then I can tryout that as well.

If you want to parse SOAP request /response in java , that is pretty much possible but its better you use XSL or jsc as it will be easy if your payload is big and even trouble shooting will be better .

Depends on what you are comfortable with though .

Thanks again for reply.

I have to call one or two service from APIGEE depend on the condition. Here is the scenarios.

1. Client -> APIGEE -> Login Service -> APIGEE -> Backend Service -> APIGEE -> Client

2. Client -> APIGEE -> Backend Service -> APIGEE ->Client

3. Client -> APIGEE -> Backend Service -> APIGEE -> Login Service -> APIGEE -> Backend Service -> APIGEE -> Client

Login Service will be call when The session id is not available in Key Value map of APIGEE or the session id in invalid.

So i thought to put this all logic in javascript. however login service is SOAP service and backend service is REST service.

I was not able to send the payload and not able to parse it using javascript.
