Can't filter leads by custom field in Kommo "Search Leads" module

Questions

Hi! I’m trying to build a scenario where I search for a Kommo lead using a custom field (booking_id) that comes from SimplyBook.

Here’s what I’m doing:

  • I save the booking_id (e.g. 82) in a custom text field in the lead when it’s created.
  • Later, when I receive a cancellation event from SimplyBook, I try to find the corresponding lead by filtering on that custom field in the “Search Leads” module.

What I’ve tried:

  • Using the “Custom Fields Values” input with:
    {“1292792”: “82”}

(Where 1292792 is the internal ID of the booking_id field, confirmed inside Kommo.)

  • I’ve also tried with other formats like {“booking_id”:“{{1.booking_id}}”} and others..
  • All other filters are disabled (e.g., no “Closest Task at”, etc.).

Problem:
The module returns an error:

[400] Bad Request: Invalid filter for current account

It seems like the “Custom Fields Values” input is either not supported in my Kommo account, or I’m not formatting it correctly.

  • I confirmed that the field exists and has the correct value.

Has anyone successfully filtered Kommo leads by custom field using Make? Or is this simply unsupported?

Thanks in advance :folded_hands:
