Credentials

Add an Instica EPR API credential with an API key. A key starting with ik_test_ works against the sandbox. The credential test calls the whoami operation.

The Instica EPR node

• SKU: get many, get one, and import a CSV from a binary field.
• Volume: import a CSV and optionally wait for the import job, which fails the node if the job fails.
• Obligation: get many results.
• Report: generate (opens a period, runs the checks and seals it), list periods, and download a report file into a binary field.

The Instica EPR Trigger

The trigger starts a workflow from the events you pick, using the same event list as the Webhooks page. Activating the workflow creates a webhook endpoint and keeps its signing secret in the workflow. Deactivating it deletes the endpoint.

Every delivery is checked against the Instica-Signature header before the workflow runs. A request with a missing, wrong or old signature gets a 401. Events can arrive more than once, so use the event id to skip repeats.
