Snowflake REST Data Connector in JMP 19

Feli — Mon, 16 Feb 2026 08:47:43 GMT

I was wondering if anybody has used the new Snowflake REST Data connector in JMP 19 to connect to a Snowflake database successfully.

The documentation on how to use it (JMP 19 Help ) is a bit sparse and generic and now I am left wondering on how to best configure the data connector for my Snowflake data base and if there is anything I have to change on the Snowflake side since I am mostly getting Login failed error messages .

How were you able to get it running?

The 405 error occurs when Snowflake changes from Synchronous to Asynchronous processing due to loads on the data server or length (time) of query. This has been now been addressed.
The upcoming JMP 19.1 and JMP 20 releases now handle this.
You can join the JMP 20 EA program and try it as soon as the first EA comes out.

Additionally, I assume you're using username/password login?
That is similar to traditional database managed logins, so you have to make sure you have an account there.

JMP can use OAuth2 logins as well, but you'll probably want to contact tech support for guidance.
