KLAVYIO modules are working well?

Hello,

is somenone using KLAVYIO module to create an email campaign?

KLAVYio is a platform like MAILCHIMP and BREVO.
For other projects I use BREVO module in the scenario, that is so easy, but for this project I have to use KLAVYIO.

In MAKE are available some klavyio modules.

My goals is: Take from google sheet data (Subject, content, images), and automate Campaigns scheduling these.

I tried to use KLAVYIO modules in MAKE, but my results are so poor.

SCENARIO:
First module used is a custom webhook, that goes to retrive the data from a google sheet.

Second is a KLAVYIO create campaign, that works creating a draft in Klavyio, and assagning other properties. One of this is an ID messages (that will be requested from the third KLAVYIO module), but without a Subject and content of the campaign. This first module is not sufficient to automate the proccess.

Third I retrieves data from KLAVYIO list campaign , so I can have the message ID.

4th module is KLAVYIO make an API calls.

See the screenshot:

In the Body field, I try a banch of JSON code, but without a solution.

I visited the API documentation in Klavyio but no solution found. I’m not a developer, and I have diffcult to read that language found there.

Is Someone using these modules, and what are the results?
Could you share the right JSON code, the right modles to use?

Best regards

Michele
