I am trying to add environment variables into Matillion via the Matillion API using the SimpleHTTPOperator in Airflow.

&nbsp;

I am using this base url (dox: [https://documentation.matillion.com/docs/2768621](https://documentation.matillion.com/docs/2768621)): http://\<InstanceAddress\>/rest/v1/group/name/\<groupname\>/project/name/\<projectName\>/environment/name/\<environmentName\>/variable/import

&nbsp;

Here is my code

 ![0694G00000KR5JsQAL_0D54G00008QNpFESA1](https://us1.discourse-cdn.com/flex002/uploads/matillioncommunity/original/1X/e5cf2e3cb206e837b57316733bed0bf48fff332c.png)

There is nothing wrong with my http\_conn\_id since I am able to update env vars via the POST [/set/instance](https://documentation.matillion.com/docs/2768621#2-4) API endpoint. However, I would like to import variables as opposed to just update them.

&nbsp;

The error I am getting is:

"ERROR - {“success”:false,“msg”:“Unrecognized token ‘objects’: was expecting (‘true’, ‘false’ or ‘null’)\n at [Source: (org.glassfish.jersey.message.internal.ReaderInterceptorExecutor$UnCloseableInputStream)

”

&nbsp;

I am not sure what ‘objects’ or ‘version’ in the post body is referring to.

&nbsp;

Any help would be much appreciated. Thank you.

Just answered my own question!

&nbsp;

For anyone interested, I just had to add 'json.dumps(env\_vars)' in the 'data' parameter of the DAG.
