Send “PATCH” method with HTTP Adapter on CPI

Summary

Learn how use ‘PATCH’ method HTTP Adaper CPI

Introduction

These days I had some trouble with a requirement of an iflow trying connect to a Rest API through ‘PATCH’ method. So, I want to share how I overcome this requirement.

Problem:

• How HTTP adapter looks like

Picture 1

• Some methods are available on CPI as we can see picture 2 and looking in other tool like postman(picture 3) we can see other possibilities.

• So, when I try to send a message with any of these methods available on CPI to the endpoint with “PATCH” method I got a message like “method not allowed”

Solution:

• To solve that we need to create a “Content Modifier” declaring the header camel property “CamelHttpMethod” and the source value need to be filled with a method of your need, in my case was “PATCH”.

• After that, just need to adjust the Adapter choosing a dynamic method, insert the expression “${header.CamelHttpMethod}” and deploy your iflow
