Hi, I’m using M2Web API, and have been receiving the following error message when I tried to do a UpdateTagForm for change a tag value: {“message”:“Internal error [Session does not exists]”,“code”:500,“success”:false}
I could do it twice, but all the remaining attempts failed. At the same time just receive “Done” response to the request for the first time, I started to receive “invalid login” when trying to enter to the M2Web portal.

Is this continuing to happen? If so, please go to https://mysupport@hms.se and create a case. Your local support team will be able to assist with account issues.

Try doing your request without the session id.

Do a stateless request.
Stateless requests: There is no login/logout. Instead of passing a session id to the web
services, the consumer sends its credentials (account, username and password) in every
call. This model frees the developer from maintaining sessions.

That is from RG-004-0-EN-(M2Web API Reference Guide)

I still cannot log in from the M2Web portal and the request to update me returns the success message but then in the viewer I realize that the value is not really changing.
Any explanation for this?

Since you are in Spain, I recommend opening a case at https://mysupport.hms.se so a local support person can help you. This is not a question that can be answered without more information, so please provide them with the actual call you are making, any error messages or screen shots that could be helpful. Thanks!

Also, did you see the suggestion from tedsch?
