Workday Integrations
Studio, EIB, Core Connectors and APIs linking Workday to payroll, benefits, identity and finance systems, with 200+ integrations built.
The integration team at Hazeberg holds Workday's Studio and Cloud Connect certifications, and the vendors on your list, from ADP and Okta to DocuSign, are usually ones we have connected before.

Integration capabilities
An integration is judged on its worst day, the night a vendor changes a file format or a release moves a field. We choose the right Workday tool for each connection, build it to fail loudly rather than quietly, and keep it working well past go-live.

Who it's built for
An integration has more owners than it first appears. Here is what changes for each of them.
Every integration listed with its owner, vendor, method and schedule.
Integration accounts and API clients that see only what they need.
Workday's own tools used before anything new is added to the estate.
New vendors added to proven patterns instead of one-off builds.
Failures flagged the moment they happen, with the reason attached.
Runbooks that let any team member resolve a failed run.
Integrations tested in the preview window before each update goes live.
Retries and error handling built in, not done at midnight.
A hire or change made in Workday reaches every system that needs it.
Payroll providers and benefit carriers get changes on schedule.
Systems that agree with each other, so less checking between them.
New starters get their accounts and tools before they arrive.
How we engage
The right route depends on whether integrations are part of a new Workday rollout, already live and causing trouble, or need a team to keep them running.
What we connect
Workday holds the record, but payroll providers, carriers, identity tools and many other systems need it too. These are the connections we build, with a vendor we have worked with wherever there is one.
Workday
Worker changes sent on the pay calendar, with results and payslips brought back into Workday.
Enrollments and life events sent to carriers without a spreadsheet in between.
Contributions and eligibility kept in step with pay and job changes.
Accounts opened for new starters on day one and closed the moment someone leaves.
Hired candidates arriving in Workday as new hires, ready for onboarding.
Offer letters and contracts signed, then filed back to the worker's record.
Payroll costs, bank files and supplier data flowing to and from the ledger.
Employees and managers asking Workday questions from Teams or Slack, under their own Workday security.

Questions
It depends on the job. EIB suits bulk loads and simple scheduled files, Core Connectors and Cloud Connect cover common vendor feeds with logic Workday already provides, Studio handles complex multi-step integrations, and REST or SOAP APIs suit real-time exchanges. We choose per connection and use Workday's own tools before building anything custom.
Yes. We start with an inventory of what each integration does, who owns it, how often it runs and how often it fails. Then we document and stabilize them, and give you a clear list of what to fix first.
Workday releases major updates twice a year and opens a preview window about five weeks before each one. Release testing is routine work at Hazeberg, not an extra: integrations are run in that window, so problems are fixed before the update reaches production.
Yes. Workday's APIs work with the integration platforms and API gateways IT teams already run. We decide case by case where the logic should live, and keep it inside Workday when Workday is the main source of the data.
Yes. Workday's REST APIs and reports can be exposed to an assistant in Teams or Slack, so people can check and update their Workday data from chat. Every action runs under the person's own Workday security, so the assistant never sees more than they could.
