custom polling trigger won't work

[Ulf_W]

Hello together,

i am really getting frustrated with configure my own polling trigger in my custom connector.

I walked through the tutorial and finished it with success. Next Level was to implement my own trigger in my custom connector to the following API:

Rentman API Documenation

But everything i do the trigger occurs an error 403.

I understand it this way that the word “trigger” which power automate adds to the URL automatically is responsible for the error which means that the resource could not found. But what can i do to solve this, or isnt this the reason?

Anyway, it is important for me to get this polling trigger to run but I found not helpful content anywhere to this topic.

Maybe here is anyone who has expertise in this topic and can tell me what there runs in the wrong line.

This is the Response Header from the Test Area in the UI:

  "content-length": "766",

  "content-type": "application/json",

  "date": "Mon, 30 Nov 2020 10:04:19 GMT",

  "x-amz-apigw-id": "W0OBiFSkjoEFspg=",

  "x-amzn-errortype": "IncompleteSignatureException",

  "x-amzn-requestid": "cf33449c-7c4b-4abb-aec9-389bc0ffa83c",

  "x-ms-apihub-cached-response": "true"

Also some pics of my Setup below.

Would be great to get some feedback to know where I made my mistake….. 😊

KR and thanks in advance

Hi @Ulf_W 

Take a deep breath. You are doing wonderful. We will help you with this.

It seems like your polling request definition is incorrect. Note that the trigger url you gave is probably for webhook triggers. It should be a GET request from which you can get your request content. Please take a look at the documentation: Use a polling trigger for Microsoft Power Automate | Microsoft Docs

Also look into webhook documentation if you have any confusion: Use a webhook as a trigger for Azure Logic Apps and Power Automate | Microsoft Docs

Hey @murshed ,

thanks for your reply and your attempt to helping me with my problem.

Please allow me the following inquires:

1. Where is the point that you see that my definition is incorrect?

The Url ist set with the Verb GET.  

When is test this Request as an "Action" in the Definition i am able to request the content.

So i cant see the point where my URL is wront. It is a normal GET Request URL of the API which i try to poll.

2. Why it should be probably a Webhook URL?

You said it is probably a Webhook URL? What is the reason you mentioned this? The API dosn't have any Webhook Trigger possibility. That is the reason why i try to configure a polling trigger.

I read the documentation minimum three times and understand the polling trigger function the way that it should work with normal GET Requests and with referencing a state value in which could be a defined value of the response.

Is there any point where my thought are wrong?

KR and many thanks until here..... 🙂

hey together, small push for my still unsolved problem. Is there anyone who understands my problem?

Would be great to get a hint. BR

Struggling on the same problem. I managed to remove "trigger" in the url by tweaking the swagger editor (on path I simply removed trigger). It works, but I am getting other errors #frustrated

Hey pieronegridev, in the end i just use HTTP Premium Connector with Recurrence Trigger to Poll by myself.
