{tocify} $title={Table of Contents} Introduction Most of the time, there is a need to have a configuration store where we can store key-value settings and consume stored settings from applications. Same is true with Logic app as well, in few scenarios we do need to have such store. Is there any way in Azure Logic App to create and use configurable values? In case of Logic app consumption - there is no such provision. Following post shows an example about how to do it with help of Azure Table storage - Using Azure Storage Account Table as Config Store  for Logic Apps Consum ..read more

{tocify} $title={Table of Contents}   The adoption of microservice architecture for building complex solutions on Azure is the trend these days. Although it offers greater scalability and reliability when compared to monolithic architectures, it becomes difficult to see how the data flows across the independent services involved in an application. Distributed Tracing was introduced to mitigate this significant drawback. So, this article will give you a high-level view of distributed tracing and points out a way to effortlessly achieve it for Azure/Hybrid applications built on top of mic ..read more

{tocify} $title={Table of Contents} Introduction One of the thing we need to identify while starting with any Integration project is whether the scenario demands for message based integration or event based integration. When there is need to sync the systems and data is involved, message based integration should be designed, whereas when some action is to be taken based on some state change then event based integration should be used. Message : Set of data produced by a system. Event : Is a notification about some objects state change.  As per the need, integration can be buil ..read more

{tocify} $title={Table of Contents} Introduction I stumbled upon a scenario where I had to decide whether a section of actions in Logic app workflow is to be executed or not based on a flag. If Flag is True, then execute those actions else no. Using IF Else is what is to be done, but the value(flag) to be checked is not part of data coming in.  It has to be stored somewhere which needs to be referred at runtime, as the flag value would be changed by Business Team as per their need. Now the question was where to store it? Options are in config file stored as blob, in a SQL Table bu ..read more

{tocify} $title={Table of Contents} Issue In a workflow there was a need to use already existing workflow(logic app) - thus added an action which calls a Logic app and all looked fine. Note : Only http trigger based logic app can be called. However, at run time, got the following error NestedWorkflowDoesNotContainResponseAction. To wait on nested workflow '3d9643d5977b44c48d632218e5f39407', it must contain a response action. Why it happened As the error says, " Nested Workflow Does Not Contain Response Action" - that means the child logic app which is been calle ..read more
