Authenticate with the iCIMS Talent Cloud API using OAuth 2.0 Client Credentials and search jobs

Steps

1. Work with iCIMS to provision an integration user account and obtain a client_id and client_secret for OAuth 2.0 Client Credentials Grant; store the client_secret in an environment variable.
2. POST to the iCIMS OAuth 2.0 token endpoint with grant_type=client_credentials, client_id, and client_secret to obtain an access_token; include the token as a Bearer in the Authorization header for all subsequent API calls.
3. To search for jobs, POST a searchJson filter body to https://api.icims.com/customers/{customerId}/search/jobs; include at least one filter (e.g., job.jobpost.isposted=true) as the Search API rejects filterless queries.
4. The Search API returns up to 1,000 system IDs per page sorted ascending by ID; paginate by appending a filter on job.id with operator > set to the last returned ID and repeating until fewer than 1,000 results are returned.
5. Fetch full job details for each system ID via GET /customers/{customerId}/jobs/{systemId}; use the staleness parameter on search requests to balance freshness against cache performance.
