API /session v3 no longer works

[tfyfe]

Hi, I have been using the REST API for some months now successfully and as of this week it has stopped working. 
 

I am trying to login to my demo account. I receive the following error in my app and also on the API companion. 

 

V2 of the /session API works fine with the same username, password, api key etc.  
 

URL

https://demo-api.ig.com/gateway/deal/session

Headers

Name=Value

Content-Type=application/json; charset=UTF-8

Accept=application/json; charset=UTF-8

X-IG-API-KEY=my api key

Version=3

Body

{
    "identifier": "my username",
    "password": "my password"
}

 

Result

HTTP 401

status: error


content-length: 50
content-type: application/json

 

{
    "errorCode": "error.security.oauth-token-invalid"
}

Had the same issue. I emailed the helpdesk and they said

That is a known issue that our team is currently investigating.  You  can reference

INC0761055 should you need an update on it.

I have the same issue, started yesterday evening:

trading_ig.rest.IGException: HTTP error: 401 {"errorCode":"error.security.oauth-token-invalid"}

I run everything via git/container and therefore  confident I have not changed anything.

I do run multiple sessions (3x) using the same account, wondering if this is now being stopped.

I have not had a single issue for more than a year.

Yeah, I have exactly the same issue.  Waiting on this to be resolved by IG asap.

I have the same issue and it is sourced from IG server. How many people have this issue out there?

[AndrewT]

This issue appears to be resolved now. It is working for me now.

The posts here enabled me to achieve what seems to be a workaround for the problem by switching to using V2. I am not sure there is any disadvantage to this.

[AndrewT]

I spoke too soon, the /session endpoint is fixed but other endpoints (/prices) still having issues

I had this issue yesterday actually, The API needs to be better documented. It seems to be abandoned but VERY helpful and useful for some of us. The only way I find out is by literally looking at the JSON responses as the documentation is out of date.

same issue. it works on and off at the moment. An hour ago it worked, now not anymore again

[Shellman]

Same for me, it stopped working this week with no changes to my code base. 
I can sort of get the api companion working at labs.ig,com but i can't for the life of me figure out how that can work by my code doesn't. 

[Craig]

Mine is still broken

[TheGuru12]

v3 has never worked for me I am on v2 and that works fine. Possibly because the documentation is wrong.
