Where to find it: Settings → Integrations → ATS → gear icon
Candidates are in the ATS but don't come into Klaaryo
Check in this order:
- Synchronization history: is the last Applications sync Completed?
- Daily usage and Monthly usage: if they're at the limit, syncing is stopped. See Read the sync history.
- Did the campaign come into Klaaryo? If not, see Choose which campaigns to sync.
- Is the application within the import period? See Which applications to import: period, start date and reference date.
- Is Candidate synchronization on, with times that cover the moment of the application?
Then use Resync now. If the candidate came in but stays "To contact", see Candidates who don't come in or stay "To contact".
Candidates arrive late
They arrive at the first sync after the application. Check times and days in When and how campaigns and candidates are synced. With ATSs connected through Kombo, like SAP SuccessFactors, data can arrive up to about 3 hours later.
The candidate moves forward in Klaaryo but the status doesn't change in the ATS
The Klaaryo status isn't mapped. See Map Klaaryo statuses to ATS statuses.
A campaign is active in Klaaryo but closed in the ATS (or the other way around)
The status is realigned at the campaign sync. If it's locked with the padlock, it stays as you set it. See Pause a campaign.
I closed the job ad in the ATS but I still have to hold interviews
The campaign in Klaaryo is paused and no more automatic invitations go out. You can invite manually, or ask your Klaaryo contact for a Campaign closing delay.
The campaign location always goes back to the one in the ATS
At every sync the locations are taken from the ATS. Fix the location in the ATS. If Use store names as location name is on, the candidate reads the location name: see Change the location name the candidate sees.
I added a status in the ATS but can't find it
Use Refresh statuses or Manage statuses in Status mapping.
I changed a campaign's invitation mode but it went back to how it was
At every sync the campaign takes back the values from the ATS settings. Change the Interview mode there. See Default values for campaigns and candidates.
