## Before you call it

1. Have a company admin create the key at app.payfit.com/integrations/hub/api with only the scopes the task needs. The key is shown once
2. POST the key to `https://oauth.payfit.com/introspect` to get `company_id`, then call `https://partner-api.payfit.com/companies/{companyId}/...`
3. Page lists with `nextPageToken` and `maxResults`, which defaults to 10 and stops at 50
4. Check before repeating a failed POST. There is no idempotency key, and `POST /absences` creates an absence that is already validated
5. A collaborator or contract created through the API stays incomplete until an HR admin finishes it in the PayFit app, and a new contract takes 2 to 5 minutes to appear

## Connect

```bash
curl --request GET --url https://partner-api.payfit.com/companies/{companyId} --header 'Authorization: Bearer YOUR-API-KEY'
```
