Kommo phone integration

Not a standalone one. Calls are logged as notes and events on the entity card through POST /api/v4/calls. The endpoint does the phone matching and the attaching in the same request.

The call record is still created, but it is linked to nothing. Kommo's docs are explicit about this. If you want the call to be visible you have to create an incoming lead for that number yourself, which is what Allo does.

Because Kommo has two lookups with different rules. The Call event uses the last 8 digits and prefers contacts. Get contacts by phone uses the last 7 digits and prefers companies. Pick one path and use it everywhere, or you will get inconsistent attribution.

No. Kommo matches on trailing digits, so the country prefix is effectively ignored. That is convenient for matching and risky for anything else, because two numbers in different countries can share the last 8 digits.

Seven requests per second, enforced per IP address. Repeated violations return 403 for that IP rather than 429, so a badly behaved backfill can lock out everything else running from the same host.

Yes. Refresh tokens last three months, and an integration that goes unused for that long loses access and needs reauthorising. Low volume accounts are the ones that get caught.
