webhook - type

[slx299]

Hi

 I am new to webhooks, not sure what I am not doing right. I follow all steps from here

How to Trigger Power Automate on N:N Relationship in Dynamics 365 - (whizzwave.com)

When I register the webhook I get message :Error – Unable to retrieve the TypeName

I used 4 query string parameters as in example.

Then when I trigger the webhook from D365 I get message :
The webhook call failed because the http request received non=success httpStatus code. Please check your webhook request handler.

when HTTP request is received has the following structure
https://prodXX/workflows/YYY/triggers/manual/paths/invoke?api=2016-06-01

when I register the webhook I only need to set this
https://prodXX/workflows/YYY/triggers/manual/paths/invoke

+ 4 query string parameters ?

thank you

Hi @slx299 ,

Please follow step by step as below to troubleshoot the issue, 

1. Error - Unable to retrieve the TypeName:

   • This error typically occurs when there's an issue with the way you're configuring the webhook registration. It could be related to the format of the request or the parameters being passed.
   • Double-check the configuration of your webhook registration in Power Automate. Ensure that you've correctly set up the webhook URL and any required query string parameters.
   • Verify that the query string parameters you're passing match the expected format and are correctly mapped in your Power Automate flow.
   • Make sure that you're using the correct HTTP method (POST, GET, etc.) when setting up the webhook.

2. The webhook call failed because the HTTP request received a non-success httpStatus code:

   • This error suggests that the webhook call made from Dynamics 365 to Power Automate is not successful. It could be due to various reasons such as authentication issues, incorrect URL, or invalid parameters.
   • Double-check the webhook URL configured in Dynamics 365. Ensure that it matches the URL of the webhook registration in Power Automate, including any query string parameters.
   • Verify that the authentication credentials (if any) required for accessing the webhook endpoint are correctly configured.
   • Check if there are any additional error details provided in the response from Power Automate. This might give you more insights into what went wrong.

3. Webhook Registration:

   • When registering a webhook in Power Automate, you typically specify the base URL of your flow endpoint along with any required query string parameters.
   • Ensure that you've registered the webhook with the correct URL format and parameters as expected by your Dynamics 365 setup.

4. Debugging:

   • Use logging and debugging tools available in both Power Automate and Dynamics 365 to track the flow of requests and responses.
   • Check the logs or monitoring features in Power Automate to see if the webhook request is reaching your flow and if any errors are occurring during its execution.

Hope this should definitely help.

Hi

Thank you for reply, I am very new to webhook.

I was following the steps for the article

So I set the values as above.

This is my power automate url

https://prodXX/workflows/YYY/triggers/manual/paths/invoke?api=2016-06-01

It is created as "When HTTP request is received" not sure where I need to set the method as GET/POST

Thank you
