Three phases take you from an unconnected Ashby instance to scores landing on candidate profiles. The first is done once, by an Ashby admin. The second repeats each time you add the assessment to a job, and the third is the day-to-day loop your recruiters run for every candidate.
Swap two API keys between Colare and Ashby to open the connection.
Add Colare as an activity on the interview-plan stage where the assessment belongs.
Send the assessment and read the score on the candidate's page, without leaving Ashby.
Setup starts in Colare's Settings and finishes in Ashby's Admin area. You'll move two keys: Colare's key into Ashby, and an Ashby key back into Colare. Done once, by an Ashby Organizational Admin.
In the Colare platform, go to Settings → Integrations. The Ashby card sits under Applicant Tracking Systems, alongside Greenhouse.

The card switches to Connecting… and a connection window opens over the page.
The window lists what Colare will read from Ashby, for example Read jobs: “We can read your job data.” Read it, then click Continue.

The window now shows two keys: a Colare API Key to add to Ashby, and an empty Ashby API Key field to fill in later. Click Copy next to the Colare API Key, and leave this window open.

In Ashby, go to Admin → Integrations → Marketplace and select Colare. The Integrations Marketplace link in the Colare window takes you straight there.
Paste the Colare API Key into the integration configuration. Click the refresh button under the input box to check the key works (it reads Test API Key when you hover over it), then click Update to save.

In Ashby, open Admin → API Keys (also linked from the Colare window) and create a new key with a name you'll recognise later, for example “Colare assessment integration”.
The key needs Api Keys → Read and Candidates → Write.

Copy the key, since Ashby shows it only once. Then paste it into the Ashby API Key field back in the Colare connection window and click Set up integration. That completes Phase 1.

Repeat this phase for every job that should use the assessment. It is not a one-time setup. That includes jobs that are already open and running: adding the activity to a live job is fine, and candidates already in the pipeline can be moved into the stage afterwards.
Open the job from Jobs, go to Interview Plan, and find the stage where the assessment belongs.

Click Add Activity to… → Add Activity, choose Colare under Integrations, select the assessment, and click Add.
Open the Automation tab on the activity and turn on Automate on Stage Entry. Every candidate who enters the stage is then invited without anyone sending the assessment by hand.
The day-to-day loop. Everything here happens inside Ashby. There's no need to open Colare to send an assessment or read a result.
Automatically: move the candidate into the assessment stage. With Automate on Stage Entry turned on, the invitation goes out on its own.
Manually: open the candidate, then New Activity → Assessment → Colare, select the assessment, click Add Activity, then Start Assessment and Start.

Once the candidate finishes, the score appears under the activity on their page, with a link through to the full Colare report.

Open the job's Candidate Pipeline, turn on Advanced, click Add Field to Match, and search for “Colare assessment score”.
The connection keeps working as long as both keys stay valid. If either key is deleted or changed, in Ashby or in Colare, the integration has to be set up again from step 1.
While setup or a reconnection is in progress, your team can keep sending assessments directly from Colare.
Ashby only lets admins manage integrations and API keys, so both halves of Phase 1 are out of reach for other roles.
Yes. Turn on Automate on Stage Entry, then move the candidates into the stage.
Yes. Add the activity to the live job's interview plan and move candidates in as usual.
Check that Phase 1 finished on both sides, then email support@colare.com.
Phase 1 is done once. After that, the only recurring work is adding Colare to each new job and sending the assessment for each candidate. Both happen entirely inside Ashby.
If a step doesn't match what you're seeing on screen, check with your Colare contact before working around it.
