I cannot add an incoming webhook to ms teams channel

Question

Hello,

yesterday when I tried to add an incoming webhook I got the generic error message that "something went wrong".

Now when I hit "add" on the incoming webhook, I just get a blank page.

Following the network traffic, I found out that the request on

/connectors/IncomingWebhook/Manage/New?MailboxAddress=e880cc50-6518-49f2-9abd-549668ec3b86%401b94b413-6d28-42b0-bf1a-7bb10aa22440&client=SkypeSpaces&SSThread=19%3ApJFBJXqrH3tfd-wLD5uuJOE6xrwauZN_0znaj0OeEAg1%40thread.tacv2&HostName=teams.microsoft.com&culture=de-de&ssApiHost=de.ng.msg.teams.microsoft.com&iframe=true&SSTheme=default&isDesktopClient=false&enableConnectorApps=true&providerId=203a1e2c-26cc-47ca-83ae-be98f960b6b2

returns a server error 500.

We need this desperately. Thankful for any help!

Answer 1

We checked this from our side by creating a new incoming webhook and are able to create successfully.

Tested in Microsoft Teams version 24187.501.2981.3768. The client version is 49/24053101421.

FYI, O365 connectors within Teams will be deprecated and notifications from this service will stop. Learn more about the timing and how the Workflows app provides a more flexible and secure experience. If you want to continue receiving these types of messages, you can use a workflow to post messages from a webhook request. Set up workflow

Answer 2

We have the same issue:

When I hit "add" on the incoming webhook, I just get a blank page, sometimes there is also a message (dependng on the browser) "login.microsoftonline.com hat eine Verbindung verweigert"

I also need this feature.

Hi @Dennis B_

According to your case description, you encountered a server error 500 when adding an incoming webhook to a Microsoft Teams channel.

Teams tag is mainly focused on the general issue of Microsoft Teams troubleshooting. According to your description, your question is not in our support scope. The following suggestion is for your reference:

• Check the webhook URL: Make sure that the webhook URL you entered is correct and valid. If the URL is incorrect, it may cause a server error.
• Check permissions and network connection: Make sure that you have sufficient permissions to add a webhook to a Teams channel and that your network connection is normal. Sometimes network problems or permission restrictions may cause server errors.
• Retry the operation: If the problem persists, try to add the webhook again. Sometimes server errors may be temporary, and retrying may solve the problem.

If you still encounter problems, you can check Microsoft's official documentation for more details on creating incoming webhooks.
