Connecting my bot through Webhooks to Integromat, I can get an user id. How can I pass this attribute as a custom variable?
In this way I could implement the following "if statement":
If User ID is equal to 1234567, then go to This Interaction".

How i would like my bot to work:
The user writes /start and ONLY the first time, his/her User ID will be sent to my Google Sheets Spreadsheet.
When the user presses a button, through an if statement, some users will skip an interaction and he/she well be redirected directly to another interaction.

How can I do that through Integromat? Thank you.

I already managed to get the user id of the user through the Webhooks, I would need to know how to pass it as a custom variable, thank you.
