The API is used in the following process.
However, after you change the password of your Microsoft account, you will not be able to send messages to Teams.
You can get a token or update it with a refresh token.
The following APIs will generate error Unauthorized.
https://graph.microsoft.com/v1.0/teams/{team_id}/channels/{channel_id}/messages
If I change the password of my Microsoft account, will I not be able to use the Teams API?
I would appreciate it if someone could tell me.
@Keita Yamashiro ,
As we are mainly responsible for general question of Microsoft Teams, your question related to API is not in our scope. I will change office-teams-windows-itpro tag to office-teams-app-dev tag. Hope you get better response.
We are tracking an issue where changing password can result into it taking a long time to get access to the API again (upto 1 day). For now if you wait for a day you should get access to the API again.
Thank you for your answer.
I see that if I wait up to 24 hours, it will be available.
This makes sense, because when I tested it myself, I found that sometimes it took only an hour before I could use it, and other times it took 24 hours before I could use it.

Microsoft (personal) accounts are not supported for that endpoint, as documented here: https://learn.microsoft.com/en-us/graph/api/channel-post-messages?view=graph-rest-1.0&tabs=http
You need to use a work/Office 365 account. Other than that, make sure you have the required permissions.
Thank you for your answer.
I made a mistake, I am trying with Office365, not Microsoft account. So before I changed the password, I can send messages to Teams without any problem.
After changing the password, I can't send any more.
Have you cleared your token cache after the password change?
Thanks for the reply.
I have not cleared the cache of the token.
After changing the password, the token is retrieved again using the following API.
/oauth2/v2.0/token
If I am using the API, how do I delete the token cache?
