Replace request payload json parameter

[vishnukolli551]

We are sending this request payload in body

Sample json:-

1. {
2. "employee": {
3. "name": "sonoo",
4. "salary": 56000,
5. "married": true
6. }
7. }

From above payload while "salary" place

1. {
2. "employee": {
3. "name": "sonoo",
4. "income": 56000,
5. "married": true
6. }
7. }

Backend service accepts only income pay load but i need to send request body as salary element

How to transform this payload in apigee before sending request

Can any one suggest me

Yes, you can do that kind of thing very simply; I recommend that you use a JS callout to perform that replacement. Here's what the JS code would look like:

/* global context */
/* jslint esversion: 6 */

var c = JSON.parse(context.getVariable('request.content'));
c.salary = c.income;
delete c.income;
context.setVariable(JSON.stringify(c));

And the JS policy configuration is also simple:

<Javascript name='JS-1' timeLimit='200' >
  <ResourceURL>jsc://modifyRequest.js</ResourceURL>
</Javascript>

On the doc page, you can learn how to add a JS policy to your API Proxy. There's a quick screencast describing the process.

@Dino-at-GoogleThanks it's working

I love it when that happens.

Is this correct ,context.setVariable(JSON.stringify(c)); ?

I think it should be something context.setVariable('request',JSON.stringify(c));

[dknezic]

context.setVariable('request.content', JSON.stringify(myMeaningfulVariableName))

You should probably use trace to confirm the content-length header is being generated correctly too
