Creating a custom connector - returns function instead of json

[Gareth1]

I'm in the process of creating a custom connector for the Australian ABN Lookup service. The issue I am running into is that the service returns the results wrapped in a callback function 

callback({"Abn":"","AbnStatus":"","Acn":"","AddressDate":null,"AddressPostcode":"","AddressState":"","BusinessName":[],"EntityName":"","EntityTypeCode":"","EntityTypeName":"","Gst":null,"Message":"Search text is not a valid ABN or ACN"})

I was wondering if anyone has come across a way to remove the callback section of the string in the connector so that valid JSON is returned to the flow

My other option with the lookup service is to return XML but I believe that this will cause other issues

Hi @Gareth1 

You could do the replace function to remove the callback text. Please see below.

The replace expression I used above is

replace(replace(variables('CallbackJSON'),'callback(',''),')','')

Hi @Gareth1 ,

I have made a test on my side and @abm 's solution is work, you could also take a try with substring() function, the screenshot of the flow as below:

The expression in the Compose 3 as below:

substring(outputs('Compose'),9,sub(length(outputs('Compose')),10))

Flow would run successfully as below:

Hi @v-alzhan-msft 

I ended up using your suggestion in case there are any brackets in the response that should be in there (such as company names)

I was hoping to handle this in a custom connector so that it could easily be shared by end users, however I could not find anything for this. The closest I could find was the policies however this seems a bit limited at the moment and doesn't have anything that I think might work here

Hi @Gareth1 ,

I'm afraid that it is not easy to handle it in the custom connector.

Hi @v-alzhan-msft 

I thought that might have been the case

Thanks for your help

Hi @Gareth1 did you ever find a solution to this? I need my flow to look up ABNs to verify they are valid.
