I am attempting to create a custom connector for the Clio API (https://app.clio.com/api/v4/documentation). I was able to successfully authenticate and access the API in Postman, testing out quite a few different types of requests with good results.
Then I exported the collection to a Postman file and imported it into a new custom connector in my MS Flow account as instructed at https://docs.microsoft.com/en-us/connectors/custom-connectors/define-postman-collection. As part of that process, I entered the following settings:
Scheme: HTTPS
host: app.clio.com
Base URL: /
Within the custom connector requests, all the definitions looked acceptable, except that instead of having the fully qualified request URL, they did not include https://app.clio.com.
For example, one request should use the following address:
https://app.clio.com/api/v4/contacts.json
The field in MS Flow, where URL should be entered, is grayed out and only includes /api/v4/contacts.json and looks like this:
The grayed out field cannot be typed in. Instead, I have clicked "Import from sample," which leads to a window where I can type in the fully qualified URL. After I do that and click the "import" button, the window still lists the partial URL as shown above.
At first I thought that was intentional, since I had entered the host elsewhere for the connector, and I thought that Flow would put them together to send the request to the right URL. But it did not: when I tested the operation, I got a 404 error:
{
"error": "{\r\n \"code\": 404,\r\n \"message\": \"Unable to match incoming request to an operation.\",\r\n \"source\": \"msmanaged-na.azure-apim.net\",\r\n \"path\": \"\",\r\n \"clientRequestId\": \"500779d5-356d-4c79-bf96-caf2-f5bc2919\"\r\n}"
}
When I looked at the request, this is the URL:
https://msmanaged-na.azure-apim.net/apim/clio2.5fb03ce8462066f352.5fdeb6bc35b813689d/92053762-68ce-4c1d-9085-0785-0fd98c3b/api/v4/contacts.json?type=Person
So obviously Flow is not using the correct request URL, and I cannot figure out how to enter the fully qualified request URL. Can anybody tell me what I am doing wrong?
I found another comment where someone else is having the same problem: https://stackoverflow.com/a/48813209/7191369 so I'm not the only one. Thanks in advance for your help.
Edit:
After some additional searching, the address in the request (with https://msmanaged-na.azure-apim.net) is the required redirect URL for the proxy per this post: https://powerapps.microsoft.com/en-us/blog/custom-api-with-authentication/, and is used when processing OAuth. But the crappy part of this is that I can't see the request URL so I can't troubleshoot. Is there any way to see what request the proxy server is sending out to the Clio API?
