Make Apps Basic Connection

Hi Makers,
I use a “basic” connection because my application does not manage OAuth. I use the following code:

“url”: “”,
headers: {
“x-api-key”: “{{parameters.apiKey}}”,
“Accept-Charset”: “UTF-8”,
“Content-Type”: “application/x-www-form-urlencoded”
“body”: {
“grant_type”: “access_token”
“type”: “urlencoded”,
“method”: “POST”,
“response”: {
“data”: {
“expires”: “{{}}”,
“accessToken”: “{{}}”,
“refreshToken”: “{{}}”

In modules I use connection variables.
Example :

“Authorization”: "Bearer {{connection.accessToken}}

I would like to know if it is possible to update a connection variable in a module?

Thanks for your help
