Hi there! 

 

I have this issue “Error while hydrating data from Kajabi: Unexpected end of JSON input” with Kajabi and Mailerlite. 

 

I would like a subscriber to move from a group to an other group when tag is added in Kajabi. 

 

Can you help me how can I fix this? 

 

Regards 

Csilla

Hi ​@Csilla Szabó, welcome to the Zapier Community 👋

 

I had a look, and it seems that you're running into a known bug with the Kajabi integration.

 

While there isn't a current workaround for this issue, I'm going to let the Kajabi team know that you have encountered this issue.

 

We will reach out as soon as we have any updates regarding this bug.

 

Please let us know if we can help out with anything else in the meantime!

Hi ​@Csilla Szabó 

Here is a workaround…

Zap trigger: Webhook - Catch Hook

This will generate a unique webhook URL to configure in Kajabi.

Prerequisites

To use the Kajabi app on Zapier, you must have:

  • An active Kajabi account (any paid plan - Kickstarter, Basic, Growth, or Pro). 
  • At least one purchase, form submission, or completed assessment on your Kajabi site (depending on the specific Zapier connection you want to create). 
  • A paid Zapier account, as Kajabi is a premium app on Zapier.
