Header Injection Policy

Header Injection policy adds headers to a request or response

To Start with we will create an mule application and connect it with API manager – please see how we can connect the mulesoft application to API Manager

After deployment in Cloudhub the API manager configuration will come as Active

Now we will apply the policy

Select Header Injection

Now update the policy configuration

Information needed

• Inbound Header Map – Key-value pair for injecting headers at the beginning of the message processing
• Outbound Header Map – Key-value pair for injecting headers at the end of the message processing

Lets add the required header

Click apply

Now if I hit this API then I’ll get outHeader as HTTP header in response

To see if we are getting header in request, we will add a logger to log the received headers

Now we can see the header in request as well
