Question

How can I pass an API Management REST response from one step to another in an Azure Logic App?

David Downing 706

I have my REST API registered with API Management. I added a 'get' call in a Logic App step. I'm trying to use the response in the next step, to make another REST API call.

I'm using the 'Built-in' 'Azure API Management' connector for both REST calls.

The second step needs the content from the 'get' REST call to make the 'post' call.

When I run the Logic App I'm getting the following error:

Any idea what I'm doing wrong?

Thank you.

I am guessing that you need to set the Content-Type header appropriately. If that is not it you need to provide some more information.

I'm not able to determine how to set the content type within a Logic App step.

There isn't a place to add a Header? I haven't used the API Managment connector before so can't help with details. Have you verified the API Management endpoint by using a tool like Postman or similar to make sure all is working properly on that side?

The API Management endpoints are all working. It's just a matter of taking the output from one step as the input to another step and correctly making the REST calls. There aren't many settings for these steps.

Thank you for replying.

so is the issue providing a value inside the body of a Post which I see the one not working is? Maybe the values go under Parameters and they are key/value json pairs? Just guessing though but that is what I would try. A http Post typically has the values in the body but this connector may take them under Parameters, or is there a body section. If that is where they go it might be useful to use a 'Compose' action to build the 'Parameters' value.

You don't show what the response of the 'Get' looks like - do the values there show up in the 'Dynamic Content' section? Maybe from your question you are new to Logic Apps and aren't aware of how to get the response values out....... If you know how to call the endpoint in API Management with Postman you can use the HTTP Connector instead of the API Management one to make the calls. I think understanding what calling the API looks like may be useful in how to format the data in either case.

Someone else will have to help you, I think I could figure it out but would need to see detail of what is needed to be accomplished. The 'Get' response and what the 'Post' is expecting in the body at least.

My requirement is to use the API Management, so I'll just keep digging.

Thank you again for your responses.
