@q2uantum You have to enable wrap with "wrap": true on the block you want the complete text. So for example the following
{"type": "TextBlock","wrap": true,"text": "${MESSAGE}"}
I haven't found anything (so far) to enlarge the Adaptive card.

q2uantum · 2024-07-10T12:26:10Z

Thanks @ronnyheymans The wrap: true will help me for now. I will keep looking myself for options to enlarge the Adaptive card

whanklee · 2024-07-10T18:19:31Z

If you create a new flow with workflows and change the json structure of the script it works again

create flow with following steps :

Open Workflows in teams

+new flow

choose notifications at the left

select "Post to a channel when a webhook request is received"

at the set up your flow part choose the team and channel where you want to post

create the flow

change ths JSON part in the script to the following : JSON="{"type":"message","attachments":[{"contentType":"application/vnd.microsoft.card.adaptive","contentUrl":null,"content":{"$schema":"http://adaptivecards.io/schemas/adaptive-card.json","type":"AdaptiveCard","version":"1.2","body":[{"type": "TextBlock","text": "${TITLE}"},{"type": "TextBlock","text": "${MESSAGE}"}]}}]}"

More info on the structure of an adaptive card : https://learn.microsoft.com/en-us/adaptive-cards/authoring-cards/getting-started More info on webhook json body structure : https://learn.microsoft.com/en-us/connectors/teams/?tabs=text1#example Adaptive Card designer : https://adaptivecards.io/designer/

Yes, it works.
What about "themeColor": "${COLOR}"? I tried adding this parameter, however, nothing happened.

q2uantum · 2024-07-10T18:39:18Z

@whanklee You can add \"color\": \"<options>\"

are:

Default
Dark
Light
Accent
Good
Warning
Attention

chusiang · 2024-07-12T10:47:24Z

@q2uantum Thank you for your share, I can send message to Chat via Workflows now, but I have no permission to send to Channel, so I can't verify it now.

I have put the script of teams-chat-post-for-workflows.sh .

[ [email protected] ~]
$ ./teams-chat-post-for-workflows.sh "https://prod-XXX.weXXXX.logic.azure.com:443/workflows/1XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXf/triggers/manual/paths/invoke?api-version=2016-06-01&sp=%2Ftriggers%2Fmanual%2Frun&sv=1.0&sig=BXXXXXXXXXF-fXXXXXXXXXXXXXXXXXXXXXXXXXXXXX4" "Workflows" "Default" "Send from XXXXX-ubuntu."

ronnyheymans · 2024-07-12T11:04:25Z

@chusiang You have a typo in the script :
{ "type": "TextBlock", "text": "${MESSAGE}", "warp": true } should be
{ "type": "TextBlock", "text": "${MESSAGE}", "wrap": true }

chusiang · 2024-07-12T11:17:02Z

@ronnyheymans Thank you for feedback, I have fixed it.

chusiang · 2024-07-15T09:23:02Z

I have leaved a comment to share this new script on Retirement of Office 365 connectors within Microsoft Teams | Microsoft Developer Blogs post, maybe it can help someone.

I guess, it's working now, because I am the owner role in this Teams.

Thanks chusiang , is it possible remove the user name from message ?

chusiang · 2024-07-17T10:14:56Z

Hi @wengzy , I think you need the title like "chusiang via Workflows", I can not see some options for it now.

lp-maximus · 2024-07-19T13:26:34Z

I'm also successfully using your script to post, but my backend monitoring tool has checks against Windows drive pathing. When those checks pass their data to ${TITLE} or ${MESSAGE} it contains a \ in the drive path. This is breaking the JSON with a "Bad JSON escape sequence: \ . Path 'attachments[0].content.body[1].text" error. I've tried a couple of things to correct this issue, but haven't been able to get around it. Any thoughts?

chusiang · 2024-07-22T03:00:22Z

Hi @lp-maximus,

I think we need add Escape Character for \ on L60 in teams-chat-post-for-workflows.sh.

https://gist.github.com/chusiang/895f6406fbf9285c58ad0a3ace13d025#file-teams-chat-post-for-workflows-sh-L60

I have also escape the \ char, maybe it can help you.

- MESSAGE=$(echo ${TEXT} | sed 's/"/\"/g' | sed "s/'/\'/g")
+ MESSAGE=$(echo ${TEXT} | sed "s/'/\'/g" | sed 's/"/\"/g; s/\\/\\\\/g')

Good luck.

ehouston3 · 2024-07-23T05:15:16Z

Chusiang,
Thanks for sharing your script. I was able to look at the JSON you used in your scripts and back-track it to a Microsoft Article that had the working sample JSON for incoming webhooks and most of the requirements for making a successful Adaptive Card post in Teams. There are a lot of samples for AdaptiveCard from Microsoft articles that do not work as-is in Teams. They must have the required bits from the article The JSON in the incoming webhook section below is the only JSON formatting that's been successful so far for me.

https://learn.microsoft.com/en-us/microsoftteams/platform/webhooks-and-connectors/how-to/connectors-using?tabs=cURL%2Ctext1#send-adaptive-cards-using-an-incoming-webhook

In combination with using the "body" sections of the samples from AdaptiveCards.io, I've made a lot of progress in posting various types of messages with different formatting. The examples that used data binding don't seem to be supported in Teams. The article above also calls out the elements in the schema that are and are not supported.

Additionally, for those using GitLab the webhooks work from there if the workflow accepts POSTS from "anyone"

lp-maximus · 2024-07-23T12:38:04Z

@chusiang,
Your code changes worked great for me, much appreciated.

cowbe0x004 · 2024-07-24T12:05:32Z

@chusiang thanks for your post, any idea how to get rid of the footnote message "... used a Workflow template to send this card. Get template" and to change the Workflow logo ?

You can remove the message by copying the Workflows to a new one. A new webhook url will be created. I have the original one turned off.

ehouston3 · 2024-07-24T15:43:21Z

Additionally, if you create the workflow without using a template, the footer advertisement for templates won’t be present. I think it’s there to promote the use of workflow templates to save time. You can assemble the same components that are in the template and not have to worry about the footer advertisement.

chusiang · 2024-07-25T14:02:26Z

Thanks for feedback from @cowbe0x004 and @ehouston3 ,
I have tried to remove the footer, but something is working and something not.

If we want to stop show (or remove) the footer:

Manual create the workflows, not from template. #gistcomment-5131921
Clone the working one from template, and use the new one. #gistcomment-5131697

I think the answer is clean now.

How to send a message on Microsoft teams with new line character? With \n not working. What should I use?

chusiang · 2024-09-11T14:37:58Z

Hi @whanklee , please try \n\n, it's working on https://adaptivecards.io/designer .

{
  "type": "TextBlock",
  "text": "It doesn't wrap by\n\n default",
  "weight": "bolder"
},

whanklee · 2024-09-11T14:45:00Z

Hi @chusiang,
\r\n\r\n works well.

Reference:

How to use sed to find and replace text in files in Linux / Unix shell - nixCraft

Hi,

In my case I'm passing to the script an output of another script, which takes sql query result and concats with another line having an escaped newline:
query-db-and-pass-to-teams-script.sh
MESSAGE="$SQL_RESULT" # Which is a 5 line string, 1st 4 ending with literal newlines.
MESSAGE+="\nAnother line here"
${TEAMS_SCRIPT} "$WEBHOOK_URL" "$TITLE" "$COLOR" "$MESSAGE"

So when this $MESSAGE is passed to your script, several issues occur at this line:
MESSAGE=$(echo ${TEXT} | sed "s/'/\'/g" | sed 's/"/\"/g; s/\\/\\\\/g')

If we use echo ${TEXT} - it will eat all literal newlines. Had to use echo "${TEXT}" to avoid that.
s/\/\\/g turns my concated escaped newline in "\nAnother line here" into "\\\\nAnother line here"

P.S.
echo "No status specified."
Was it meant "No color specified."?

chusiang · 2024-09-19T09:02:19Z

Hi @alaxelmck,

I have update to No color specified., it's typo with I copy from my old script like slack-chat-post.sh .

About support output of another script part, I have no idea now.
