Getting BadRequest (Unauthorized) error from ESM rest api v2 during get query result


I'm using ESM rest API v2 on ESM V11 and I sent a detailed query (qryExecuteDetail) and then I got a succeeded query details result.

I was waiting for the query to get completed (by using qryGetStatus).

When it finished, I started to fetch the query results data by separated pages of 100 items per page (by using qryGetResults).

The query returned with 2400 items thus I need to call the qryGetResults method 24 times to complete the receiving of all the data.

After the 14th page (and it's pretty consistent), I'm getting an unauthorized error from the ESM rest client. I assume it is related to the client's token validity but I don't sure what exactly to do.

Re: Getting BadRequest (Unauthorized) error from ESM rest api v2 during get query result


This is actually very interesting...  Are you using python ?


I would suggest to add a exception handling part, re-login, re-do you query (qryExecuteDetail + wait qryGetStatus), and continue fetching the pages from the 14th until the next unauthorized error, and so on...

Here is a list of string matches that can be use to detect various authorization errors from ESM responses text :

"Not Authorized User",
"Invalid Session",
"Username and password cannot be null",


Are you getting one of those ? 


If you are using python, I recommend you to check out msiempy, the ESM API python wrapper. It can significantly reduce your time spent coding script for the ESM API !
